This paper investigates the long-run nexus between wealth inequality and aggregate output using a DSGE model in which wealth inequality endogenously affects individual entrepreneurship incentives, thereby influencing aggregate output. Our model passes the indirect inference test against the UK data from 1870 to 2015. We find that shocks to aggregate TFP, entrepreneurial barriers, government grant support and general government spending played significant roles in shaping historical inequality dynamics in the UK. Directly removing entrepreneurial barriers or indirectly providing government grant support to the private sector such as through inclusive loan subsidies are effective means of reducing inequality and stimulating output growth.

This paper evaluates the economic resilience of 52 economies based on 16 indicators in three dimensions (including the government, enterprises, and the public) and calculates their disaggregate output scores using the data envelopment analysis (DEA) method to measure and compare their economic resilience in the early stage of the COVID-19 pandemic. The evaluation results show that 23 of these economies had no room for further improvement in the overall economic resilience performance at that time. Germany’s economic resilience performance, ranking 24th, is second only to these 23 economies, whereas Australia and Belgium are just behind Germany. These are the better performers among the 52 economies. Meanwhile, this paper also validates the notion that the construction of an economic resilience index is more suitable than the IMD World Competitiveness Index and the WEF Global Competitiveness Index in assessing the economic resilience of those economies during the COVID-19 pandemic. Therefore, it is more suitable for the sample countries to refer to the efficiency of each indicator in this article to formulate policy directions and goals, in order to strengthen their economic resilience under the epidemic. However, under the limitations of the COVID-19 epidemic at the time of writing this paper, the economic resilience scores measured in this paper still belong to resistance measures rather than recovery measures.

In the context of the increasing interdependence of countries due to the development of international trade, a relevant question arises as to whether it is necessary to conduct independent monetary policies for each country or whether it is advisable to coordinate these policies. This question becomes a key in the debate on optimal monetary policy strategies in open economies. The aim of this study is to analyze the impact of asymmetric aggregate demand shocks on the appropriateness of monetary policy coordination in a simple stochastic model of two interacting countries. The analysis of equilibrium states of the monetary authorities’ interaction strategies under study was carried out analytically by minimizing the loss function and solving one-period static optimization problems. The equilibrium states of macroeconomics of interacting countries under coordination of monetary policy and in cases of lack of coordination (Nash and Stackelberg equilibrium) in the presence of asymmetric, serially uncorrelated demand shocks have been analyzed. It is proven that the response of inflation to asymmetric demand shocks is smaller in the case of coordinated policy than in the case of non-cooperative policy. The loss function analysis shows that the compensation of demand shocks is found to be more costly in Nash equilibrium than in the case of monetary authority coordination policy. The analysis of the monetary authorities’ interaction strategies showed that the real exchange rate plays an important role in balancing supply and demand in the two economies.

How are unemployment and output affected if wages are set on the sector level rather than firm level? We take a new look at this question, allowing for heterogeneous firms and rent-sharing motives. Without these motives, employment and output are lower under sector-level wage-setting due to higher wage markups. With rent-sharing motives, however, firm selection is higher under sector-level wage-setting, which tends to increase employment and output, thus counteracting the markup effect. Simulations show that the firm-selection effect decreases the difference between the two unionization structures substantially but it does not change the signs of the effects on output and employment.

India is among the largest and fastest-growing economies in the world. To continue its growth, energy is and will continue to be one of its most important considerations. With a population of over one billion, India is the third largest consumer of petroleum on the globe. To maintain this ranking, India imports a large percentage of its total oil consumption. Given India’s current position as a large importer of oil, how does oil price volatility affect the Indian economy? This paper examines the effect of oil price volatility on inflation, economic growth, and the stock market in India. Statistical tests suggest that the overall price level, the real effective exchange rate, and oil prices are negatively related to aggregate output in the long run. Granger causality test results derived from a vector error correction model support bidirectional causality between oil prices and aggregate output, indicating that a change in oil prices also affects aggregate output in the short run.

Probably because of their interpretability and transparent nature, synthetic controls have become widely applied in empirical research in economics and the social sciences. This article aims to provide practical guidance to researchers employing synthetic control methods. The article starts with an overview and an introduction to synthetic control estimation. The main sections discuss the advantages of the synthetic control framework as a research design, and describe the settings where synthetic controls provide reliable estimates and those where they may fail. The article closes with a discussion of recent extensions, related methods, and avenues for future research.

The paper argues that many of the exaggerated claims that globalization has been an important factor in lowering inflation in recent years just do not hold up. Globalization does, however, have the potential to be stabilizing for individual economies and has been a key factor in promoting economic growth. The paper then examines four questions about the impact of globalization on the monetary transmission mechanism and arrives at the following answers: (i) Has globalization led to a decline in the sensitivity of inflation to domestic output gaps and thus to domestic monetary policy? No. (ii) Are foreign output gaps playing a more prominent role in the domestic inflation process, so that domestic monetary policy has more difficulty stabilizing inflation? No. (iii) Can domestic monetary policy still control domestic interest rates and so stabilize both inflation and output? Yes. (iv) Are there other ways, besides possible influences on inflation and interest rates, in which globalization may have affected the transmission mechanism of monetary policy? Yes.

Long-run growth in many models is the product of two terms: the effective number of researchers and their research productivity. We present evidence from various industries, products, and firms showing that research effort is rising substantially while research productivity is declining sharply. A good example is Moore’s Law. The number of researchers required today to achieve the famous doubling of computer chip density is more than 18 times larger than the number required in the early 1970s. More generally, everywhere we look we find that ideas, and the exponential growth they imply, are getting harder to find.

We provide evidence that democracy has a positive effect on GDP per capita. Our dynamic panel strategy controls for country fixed effects and the rich dynamics of GDP, which otherwise confound the effect of democracy. To reduce measurement error, we introduce a new indicator of democracy that consolidates previous measures. Our baseline results show that democratizations increase GDP per capita by about 20 percent in the long run. We find similar effects using a propensity score reweighting strategy as well as an instrumental-variables strategy using regional waves of democratization. The effects are similar across different levels of development and appear to be driven by greater investments in capital, schooling, and health.

This paper studies the relationship between public debt expansion and economic growth and investigates whether the debt-growth relation varies with the level of indebtedness. We contribute theoretically by developing tests for threshold effects in the context of dynamic heterogeneous panel data models with cross-sectionally dependent errors. In the empirical application, using data on a sample of forty countries over the 1965–2010 period, we find no evidence for a universally applicable threshold effect in the relationship between public debt and economic growth. Regardless of the threshold, however, we find significant negative effects of public debt buildup on output growth.
