Global energy security is a growing worldwide concern in the presence of high economic policy uncertainty (EPU) that can be addressed by advancing sustainable energy diversification (ED) practices. Energy security can be estimated by combining ED and EPU indices; hence, this study uses a dataset covering three continents and 26 countries from 1995 to 2023 to measure energy security employing this approach. The study employs quantile regression and panel data analysis, finding a positive relationship between EPU and ED. The results reveal that when EPU increases, the spectrum of energy sources declines, negatively impacting energy security. Other factors of globalization, Gross Domestic Product, gross capital formation, and the labor force also have an impact on the spectrum of energy sources. To obtain a sustainable level of ED, policymakers should increase investment in gross capital formation because economic growth and openness via pro-global policies have less impact on ED. This study also demonstrates that labor capital shifts have a significant effect on ED. The quantitative results reveal the importance of clear and precise economic policies for increasing investment in carbon-free energy security. [Display omitted] [ABSTRACT FROM AUTHOR]

In the early period of Yi Dynasty of Korea, currency and physical transactions were parallel, and the market order was chaotic. During the reign of Emperor Taejong, the Banknote Law was established and carried out, and measures such as replacing physical objects with paper money, establishing joint purchase houses and determining the crime of hiding cloth were adopted to enhance currency credit. Although the law promoted circulation, monetary reform was not smooth. In this study, based on the economic historical data of the dynasty and the game theory method, the author find that the Yi Dynasty tries to improve the relationship between the state and the grassroots society and explore new economic policies through national finance and monetary reform. The failure of monetary reform is not only a policy failure, but also a consequence of uneven distribution of interests among different subjects. [ABSTRACT FROM AUTHOR]

The recovery of the global economy in the aftermath of COVID-19 faces enormous challenges. Ensuring stable income growth of the population has become an important means for developing countries to ensure sustained economic development. Raising the overall income of the population is a public initiative that benefits all citizens; therefore, governments of developing countries should promote the implementation of relevant public policies and the provision of public goods to ensure that existing economic instruments can benefit the entire population. In this regard, public space, as a typical form of public good, may play an important role in promoting the benefits of existing economic policies for all residents. This paper examines how residents' use of public space contributes to their income growth through social capital. Hypotheses are tested based on an econometric analysis of 1565 questionnaires received from Chinese workers. The results show that residents' use of public space can indeed be an important way to increase their income, which is realized through the enhancement of social capital. The research presented in this paper provides a new influence variable of public space to improve residents' income. Further, it improves people's understanding of the three classical concepts—public space, social capital, and income—by establishing the logical connection and theoretical explanation of physical space, emotional space, and value space in human society. The conclusions of this paper highlight the important role of public space in urban and rural development planning. [ABSTRACT FROM AUTHOR]

Purpose: The farm sector is crucial for rural poverty alleviation, alongside the non-farm sector, which contributes to mitigating risks associated with crop failures. This paper investigates the effects of public policies on productive employment within both the farm and non-farm sectors in sub-Saharan Africa. Design/methodology/approach: A meta-analysis is conducted exclusively on the results of the Partnership for Economic Policy (PEP)-funded studies under the Policy Analysis on Growth and Employment (PAGE II) initiative. Selected studies focused on the impact of public policies on productive employment in rural farm and non-farm sectors, encompassing a total of nine sub-Saharan Africa countries in: Benin, Burkina Faso, Cote d'Ivoire, Democratic Republic of Congo, Ghana, Lesotho, Nigeria, Senegal and South Africa. Findings: The results indicate that public investments in rural areas and public policies that facilitate access to productive resources are likely to enhance productive employment. The overall effect size is positive and significant, ranging from 2% to 10% increases in productive employment. Sources of variation include the sector of activity and the policy instrument. In addition, the policy effects are gender-sensitive and seem more consistent in the non-farm sector. Research limitations/implications: Although the selected working papers addressed several aspects of productive employment, other aspects warrant further investigation. Policies involving restrictions or regulations have received little attention in the impact analysis. Researches to fill this gap would be important. Another suggestion for further research is the analysis of the relative importance of non-farm employment in rural areas in developing countries. It is always assumed that rural households depend heavily on agriculture for their subsistence. Originality/value: The contribution of the paper lies in the comparative analysis of numerous public policies implemented in nine distinct countries. By consolidating data from fourteen 14 different experiences into a single study, the paper offers valuable insights on factors that determine policy effectiveness and contribute to understanding what worked for whom and why.

This article from Economic Policy provides a summary of five papers that contribute to our understanding of economic and policy issues. The first paper examines the impacts of historical conflicts on the current conflict in Ukraine, emphasizing the importance of demining, preserving social cohesion, and addressing gender imbalances and conflict-related sexual violence. The second paper evaluates the effectiveness of legislation aimed at restricting the mobility of unemployed individuals within specific areas of a city, finding that these laws are ineffective and have unintended negative consequences. The third paper analyzes the macroeconomic impact of structural reforms in Italy, showing that these reforms can lead to increased productivity and GDP growth. The fourth paper presents a comprehensive analysis of China's foreign lending practices, highlighting unconventional confidentiality clauses and collateral arrangements used by Chinese lenders. The final paper explores the question of higher education subsidies, finding that increased subsidies can have positive fiscal and welfare impacts in many countries. These papers offer evidence-based recommendations and policy lessons for policymakers in various contexts. [Extracted from the article]

Green bonds are relatively new in the financial market compared to other financial securities but are useful in financing environmentally friendly projects. Just like other financial securities, green bonds are affected by various factors, such as economic policy uncertainty. Our aim of this paper was to conduct a systematic literature review of the impact of economic policy uncertainty on green bonds. We sought to do a thorough analysis of the existing literature on the assessment of the impact of economic policy uncertainty on green bonds and the techniques used in assessing the impact. Our findings showed that economic policy uncertainty had a strong impact on the green bond, with its intensity varying by location. This impact tended to be more pronounced in periods of heightened uncertainty. Also, our findings highlighted that the assessment of the impact of economic policy uncertainty on green bonds gained popularity in 2019, with China emerging as a prominent contributor. However, other countries, such as Finland, even though they had few published papers, their citations signified the production of quality papers in this field. Additionally, we found that the application of the quantile analysis method was utilized by many recent studies, which signified its importance in this field. Our findings highlighted the importance of considering appropriate techniques in assessing the impact of economic policy uncertainty on green bonds while taking into account the paper quality.

Commodities are usually used to diversify portfolios. However, their prices are affected by uncertain phenomena such as economic crises, political events, climate risk, etc. This paper examines how Climate and Economic Policy Uncertainty (measured by the CPU and GEPU indices, respectively) affect to wheat prices in the spot and future markets. By combining the wavelet transform and coherence analysis it is possible to see, graphically, the relationship between two time series and also to analyze it at different time frequencies. Although wheat spot and future prices have a similar behavior, the main results obtained in this paper show that the relationships between CPU and GEPU with future prices are stronger than with spot prices. Furthermore, futures and CPU exhibit synchronous movements, whereas futures and GEPU demonstrate antiphase behavior. However, in both cases (futures and spots) their relationship with CPU/GEPU is bounded to several time periods and some frequencies. [ABSTRACT FROM AUTHOR]

Financial market (6 papers) The paper "Do the RMB exchange rate and global commodity prices have asymmetric or symmetric effects on China's stock prices?" It suggests that hedge fund strategies' betas respond more to illiquidity uncertainty than to illiquidity risk during crises, illiquidity and VIX shocks are the major drivers of systemic risk in the hedge fund industry. Specifically, China's stock prices are more sensitive to increases than decreases in global commodity prices. [Extracted from the article]

When scholars investigate the legacy of John Maynard Keynes's Treatise on Probability (1921) for the development of Keynes's thinking, the attention usually focuses on the connections among Keynes's probability theory, his conception of decision-making under uncertainty, and the theory of the functioning of the macroeconomic system that derives from it—through the marginal efficiency of capital, the preference for liquidity, and the self-referential functioning of financial markets. By contrast, this paper aims to investigate the connections between Keynes's probability theory, on the one hand, and his economic policy recommendations, on the other. It concentrates on the policy recommendations defended by Keynes during the Great Depression but also after the General Theory. Keynes's economic policy can be understood as a framework for decision-making in situations of uncertainty: fiscal policy aims to induce private agents to change their "rational" probability statements, while monetary policy aims to allow more weight to these statements.

For the past 50 years, state and local governments in North America heavily subsidized the construction of professional sports facilities despite the fact that only private activity takes place in these facilities. Proponents of these subsidies frequently claim that they are justified because they represent viable local economic development projects. A proponents claim a new facility will "pay for itself" by generating large tangible economic benefits, including increases in tax revenues. This paper summarizes the existing literature that contains no evidence supporting these claims, along with a new literature containing evidence that professional sports events cause a number of negative urban congestion externalities like increased crime and traffic. The paper also documents trends in subsidization over the past 50 years and discusses reasons why these subsidies persist. The paper emphasizes the role played by my research in this area.

The inherent complexity of policy decision-making structures may prevent the interface between science and policy from functioning smoothly and evidence-based policies from actually being implemented, even when the results are understood and accepted by political leaders. Given the medium-run perspective of their research question, the main findings suggest that a combination of demand-side and supply-side fiscal policy measures might be more efficient as purely demand-side policies as the former policy mix also increases potential and not only actual output.

The COVID-19 pandemic has triggered unprecedented economic challenges worldwide, prompting governments to implement various expansionary economic policies to mitigate its adverse effects. Expansionary policies typically involve measures such as increased government spending, tax cuts, policy and interest rate cuts, and monetary stimulus packages to boost economic activity and support businesses and households during times of economic downturn. This research paper explores the relationship between current inflation rates and the effectiveness of expansionary economic policies adopted during the pandemic. The hypothesis posits that expansionary policies increase inflation rates across different countries. Through a comparative analysis of various countries' approaches, the study identifies the impact of these policies on inflation. Findings reveal varied effects, emphasizing the importance of contextual factors. This cross-country analysis will include developed and developing economies to understand the implications across different economic contexts. This study contributes to understanding the interplay between expansionary policies and inflation dynamics during the pandemic. [ABSTRACT FROM AUTHOR]

This study contributes to income equality (IE) literature by examining four important issues. First, the study examines the effects of foreign bank presence (FBP) on IE. Second, the paper identifies the minimum threshold level of FBP which can lead to IE. Third, the effect of economic freedom on IE was investigated. Fourth, the paper determines whether economic freedom interacts with FBP to minimise IE. The findings are based on macro data for 33 African countries from 1995 to 2020. The findings from the two-stage system generalised method of moment indicate that unconditionally, FBP reduces income inequality. Also, results from the threshold effect reveal that whilst FBP reduces income inequality, if it exceeds 52%, it may contribute to it. Additionally, the study reveals that economic freedom dampens IIE. Furthermore, economic freedom conditions FBP to reduce IE. Based on these findings, policymakers are advised to exercise caution in attracting foreign banks and to promote local financial institutions. Policymakers are also advised to implement policies to promote economic freedom. [ABSTRACT FROM AUTHOR]

China is currently focusing on the cooperative control of air pollution and CO2 emissions, as well as the mitigation of economic policy uncertainty (EPU). By using panel data from 282 cities spanning from 2003 to 2017 and a newly constructed city-level EPU index, a spatial Durbin, two-way fixed-effects model is employed, with the aim of estimating the impact of EPU on the synergistic emissions intensity (SEI) of air pollutants and CO2. Additionally, this paper investigates the potential channels through which EPU influences SEI. It also explores how pressures related to environmental protection and economic development affect the impact of EPU on SEI. The results indicate that a unit increase in EPU will result in a rise in the SEI of local cities, adjacent cities, and total cities by 930.9%, 69,162.7%, and 70,093.6%, respectively. Moreover, the channel analysis suggests that EPU exacerbates SEI by undermining the upgrading of the industrial structure, augmenting industrial structure distortion, and escalating labor market distortion. Furthermore, the effect of EPU on SEI may be lessened by an increase in environmental protection pressure, while an increase in economic development pressure may exert a positive influence. Finally, this paper concludes by recommending that policymakers should prioritize the maintenance and stability of economic policies, facilitate the advancement of the industrial structure, enhance the efficiency of labor resource allocation, and underscore the significance of managing urban air pollution and CO2 emissions.

This paper contributes to the still unresolved issue of the growth impact of government size by analysing a historical panel data set of 17 developed countries that ranges from 1880 to 2016. The unique feature of the long-time dimension allows for conducting a kind of natural experiment. Government size is closely related to economic-policy paradigms. The time span covers different economic policy paradigms, in particular, ‘laissez-faire’ before World War II and Keynesian economic policy after World War II. Before WW II government size is small, after WW II it is (has grown) big. Furthermore, this paper contributes to filling a gap in the literature by testing the non-linear hypothesis (Armey curve). We take particular attention to a key shortcoming of panel-data analysis – parameter or individual heterogeneity. Overall, this analysis suggests a systematic positive, albeit quite small, linear relationship of government size with economic growth. As a consequence, rather than concentrating their attention to the sheer size of government, policy makers are advised caring for an efficiently run and high)quality government sector as a prerequisite for a steady growth path.

In the aftermath of recent populist upheavals in Europe, nationalist economic policies challenge the overly positive view on economic integration and the reduction of trade barriers established by standard economic theory. For quite a long time the great majority of economists supported trade liberalisation policies, at least those actively engaged in policy advice or public debates. In this paper, we examine the elite economics discourse on trade policies during the last 20 years regarding specific characteristics of authors, affiliations, citation patterns, the overall attitude towards trade, as well as the methodological approach applied in these papers. Our analysis yields the following results: First, the hierarchical structure of economics also manifests in the debate about trade. Second, while we found some indications of a shift towards more empirically oriented work, quite often empirical data is solely used to calibrate models rather than to challenge potentially biased theoretical assumptions. Third, top economic discourses on trade are predominantly characterised by a normative bias in favour of trade-liberalisation-policies. Forth, we found that other-than-economic impacts and implications of trade policies (political, social and cultural as well as environmental issues) to a great extent either remain unmentioned or are rationalised by means of pure economic criteria.

Economic policy uncertainty has had an important impact on trade and sustainable economic development. Especially in some specific industries, uncertainty has increased dramatically. The extant related literature mainly analyzes the nexus between uncertainty and trade across different industries and focuses less on a specific industry. Using Chinese customs data on HS 8-digit products over the period of 2000–2013, this paper first investigates the impact of both foreign economic policy uncertainty (EPU) and domestic intra-industry trade on China's mechanical and electrical product exports to 23 trading partners and applies pooled OLS regressions to conduct an empirical study. This paper finds that EPU has a significant inhibition effect on mechanical and electrical product exports; conversely, intra-industry trade can both significantly promote exports and alleviate the inhibition effect of EPU. In addition, the export impact of EPU varied with different trade patterns. It can significantly inhibit processing exports, while it has no effect on ordinary exports. The results of this paper indicate that in the context of increasing uncertainty, our findings could have far-reaching policy implications for China to build a new development pattern of domestic and international dual circulation.

Data factors have become one of the five essential production factors, but their role in economic growth has always been ambiguous. Starting from AI technologies, this paper establishes an endogenous growth model of data factors affecting economic growth, constructs the generation path and value path of data factors, and estimates the value of new data factors at the provincial level in China from 1999 to 2018 accordingly. Based on theoretical analyses and empirical tests, it clarifies that data factors have a "two-dimensional driving effect" on China's economic growth, that is, data factors can drive growth both directly through its own economic growth effect and indirectly by promoting technological progress. Furthermore, this paper makes three extended discussions, aiming to make a trial study on the impacts of local government big data transaction platforms on data factors and their growth effects, discuss whether it is possible to reduce the uncertainties of local economic policy based on the nature of data factors, and make a preliminary survey of the output elasticity of data factors between 1999 and 2018.

In this paper we analyse why an understanding of the global 'non-system', in which we now live, took so long to arrive after the Bretton Woods system collapsed in 1971. We first describe how knowledge of how an inflation-targeting regime would operate—what we call 'Taylor-rule macroeconomics'—was only gradually created during the 1970s, 1980s, and 1990s. We then describe how, subsequent to this, an awareness emerged, also gradually, of how the international non-system might work, depending, as it does, on Taylor-rule macroeconomics being already in place. We then discuss the Great Moderation, making clear that a well-functioning global non-system would require not just inflation targeting and floating exchange rates in each country, but also adequate fiscal discipline, and a satisfactory form of financial regulation. We describe how a well-functioning version of this global non-system would actually fit together. We then discuss how this non-system has responded to two enormous challenges of the last 15 years, namely the Global Financial Crisis and the Covid pandemic. This discussion of what has happened in the recent past provides the background to a discussion, in the companion paper by Subacchi and Vines in this issue of the Oxford Review of Economic Policy , of the challenges that the global non-system will face in the future.
