Does the introduction of stock exchange markets boost economic growth in African countries?

We assess whether the introduction of private equity capital markets affects economic growth in African countries. We address this issue by focussing on stock exchange markets as the predominant type of new equity markets, using a Diff-in-Diff regression method. The analysis uses a panel data set from 48 Sub-Saharan countries over the time range of 1970–2018. 23 countries are part of the “treated” group – which introduced international stock exchanges – and 25 “untreated” countries serve as the control group. Our results show that when compared with the time period prior to the introduction of stock exchange markets, GDP per capita rises by the amount of 532 US$ (around 40% of the Sub-Saharan average) after the introduction of equity capital markets in the treated countries. Over the ten years post introduction, the effect is hump-shaped, with effects becoming statistically significant from the first year after implementation, with a peak in the 5th year, and it then becomes statistically insignificant from then onwards.     

World economic convergence: Does the estimation methodology matter?

An extant empirical literature produces evidence on economic convergence using methods that assume an underlying deterministic trend. Competing approaches that assume a stochastic trend, however, produce only limited evidence of economic convergence. In this paper we address this puzzling feature of the literature by providing a comprehensive analysis of economic convergence using three methodologies that cover all possible underlying assumptions: deterministic, stochastic, and combination trends. We also develop a method for an overall Stochastic Convergence Rate Index, that combines the outcomes of alternative stochastic tests and provides a single measure of the intensity of stochastic convergence. We consider 135 economies over the period 1980–2017. We find that economic convergence occurs at a global level through the formation of convergence clubs, and economic convergence emerges as a deterministic rather than a stochastic process. Tests that ignore deterministic trends tend to understate the evidence for convergence.     

Growth under exchange rate volatility: Does access to foreign or domestic equity markets matter?

Employing a firm-level dataset, this paper explores the effects of exchange rate volatility on the growth performances of domestic versus foreign, and publicly traded versus non-traded private manufacturing firms in a major developing country, Turkey. The empirical results using dynamic panel data estimation techniques and comprehensive robustness tests suggest that exchange rate volatility has a significant growth reducing effect on manufacturing firms. However, having access to foreign, and to a lesser degree, domestic equity markets is found to reduce these negative effects at significant levels. These findings continue to hold after controlling for firm heterogeneity due to differences in export orientation, external indebtedness, profitability, productivity, size, industrial characteristics, and time-variant institutional changes.     

Immigration and economic freedom of the US states: Does the institutional quality of immigrants' origin countries matter?

When people immigrate to the United States from countries with less economic freedom, they do not dampen economic freedom in their destination states. We use the Economic Freedom of North America report to rate the economic freedom of US states, and we group immigrants by how far below the United States their origin countries score in the Economic Freedom of the World report. Our major findings hold true even when states receive immigrants from countries with far less economic freedom. Most relationships between immigration and the US states' economic freedom scores are neither statistically nor economically significant.     

Intraday bidirectional volatility spillover across international stock markets: does the global financial crisis matter?

This article studies volatility spillover between the US and the three largest European stock markets (Frankfurt, London and Paris) around the time of the recent Subprime crisis. In order to investigate the impact of the latter, we break our sample down into two sub-periods: a pre-crisis period and a post-crisis period, using a structural break test that has the advantage of endogenously testing for further breaks in the data. Unlike previous studies that have frequently investigated this issue using low frequency data, our article makes use of intraday data. Accordingly, using Threshold generalized autoregressive conditional heteroscedasticity (GARCH) model estimations, we find weak evidence of volatility transmission between the two regions before the Subprime crisis. However, during the post-crisis period, we record returns and volatility spillover from US to European markets and vice versa at different times of the trading day, indicating that the two regions became more dependent during the recent Subprime crisis, a finding that supports the contagion hypothesis between the US and European stock markets.     

Measuring inefficiency in the presence of bad outputs: Does the disposability assumption matter?

Multiple approaches to incorporate environmental pollution in production technologies have been proposed. In this paper, we analyze the consequences of these theoretical models for applied research. Our comparison focuses on alternative disposability assumptions imposed on bad outputs and their effects on the measurement of productive efficiency. Using empirical data on electricity generation in the US, we quantify and analyze differences among the theoretical models. Moreover, Monte Carlo simulations are conducted to evaluate the ability of the models to correctly estimate inefficiency given varying specifications of the pollution-generating process.     

Transmission of shocks across global real estate and equity markets: An examination of the 2007–2008 housing crisis

This study analyses the impact of the 2007–2008 U.S. financial crisis on the structure of interdependence among several major global real estate and equity markets. Moreover, it performs a step-by-step comparative analysis to evaluate similarities and differences in the convergence patterns of global real estate markets vis-à-vis global equity markets. Long-run results indicate that global real estate markets were less integrated than global equity markets prior to the crisis. Since the crisis, however, both global real estate and global equity markets have become highly integrated with the U.S. real estate and equity markets, respectively, and have fully converged. Short-run analyses indicate that during the pre-crisis period, global real estate markets were highly exogenous and independent. In contrast, global equity markets were comparatively more interdependent with one another and more endogenous. After the crisis, however, both global real estate and equity markets reacted strongly to shocks emanating from the U.S. markets, although the impact of the U.S. real estate market on the global real estate market is more pronounced than the effect of the U.S. equity market on the global equity markets. Finally, the study shows that U.S. real estate and equity markets are the channels of transmission or the sources of trends that drive global markets over the long-run and the short-run.     

Idiosyncratic and international transmission of shocks in the G7: Does EMU matter?

This paper analyzes the transmission of shocks across the Group of Seven industrialized countries (G7) before and after the introduction of the euro. We estimate global vector autoregressive (VAR) models for different periods to investigate changes in the domestic and international adjustment of macroeconomic variables following supply, demand, and nominal shocks. The shocks are identified with robust sign restrictions, which we derive from a small open economy dynamic stochastic general equilibrium (DSGE) model. Specifically, we analyze the adjustment of output, inflation, and the real effective exchange rate following those shocks. Our results indicate that changes in the adjustment are due to global convergence rather than to regional‐specific convergence.     

The effect of immigration on unemployment in Europe: Does the core-periphery dualism matter?

The migrant crisis is one of the most challenging tasks the EU has ever faced. This paper uses a Panel Error Correction Model to assess the direction of the impact of immigration on domestic unemployment, in the short and in the long run, for a sample of 15 EU countries between 1997 and 2016. We test for different effects in core and periphery countries based on differences in macroeconomic fundamentals and labor market characteristics. In the long run, immigration is found to reduce unemployment in peripheral countries only, whereas in the short run, we find that immigration reduces unemployment for the whole sample. However, country-specific coefficients based on interactions with labour market characteristics indicate that short-run impacts are larger in Scandinavian and Anglo-Saxon countries. Conversely, Italy, Greece and Portugal show the smallest impacts. Our results suggest that negative sentiments toward immigration due to labour market competition are mostly unjustified.     

Graduate employment: Does the type of higher education institution matter?

The paper analyses whether the type of institution from which students graduate has an impact on their unemployment propensity. It uses official data on the Portuguese higher education system, for 2018, at the program/institution level, which provides information on graduate unemployment, as well as demographic and socioeconomic background information. A fractional probit model on graduates’ propensity for unemployment is estimated. Results suggest that polytechnic graduates face higher unemployment propensity than university graduates, maintaining inequalities present in students’ previous trajectories. Policies targeting socioeconomic segregation need to address not only access to higher education but also the transition to the labor market.     

Does size matter? Implications of household size for economic growth and convergence

We assess the effects of changes in household size on the long‐run evolution of living standards and on cross‐country convergence. When the observed changes in average household size across countries are taken into consideration, growth in living standards is slower throughout the 20th century as compared to a measure based on per capita GDP. Furthermore, the speed of divergence between different countries before 1950 is faster and the speed of convergence after 1950 is slower after adjusting for the evolution in household size.     

Could the global financial crisis improve the performance of the G7 stocks markets?

Financial crises are normally associated with negative effects on financial markets. In this article, we investigate whether the most recent global financial crisis (GFC) had any positive impact on the G7 (Canada, France, Germany, Italy, Japan, the United Kingdom and the United States) indices. To conduct the analysis we employ the mean–variance (MV) analysis, CAPM statistics, Hurst exponent, runs test, multiple variation ratio test and stochastic dominance (SD) tests. Our MV and CAPM results conclude that most of the G7 stock indices are significantly less volatile. The results from Hurst exponent, run tests and multiple variation ratio confirm that efficiency improved in the post-GFC period. Finally, our SD results conclude that there is no arbitrage opportunity and the markets are efficient due to the GFC, and, in general, investors prefer investing in the indices after the GFC. Overall, we conclude that the GFC led to markets that are more efficient and mature, confirming that crises can also have positive impacts on stock markets. These findings provide important information for investors and market regulators.     

Does the star power matter?

This study investigates the role of superstars in the Korean movie industry. We apply a two-step approach: the first step is to test the significance of the star power during 1988–1999 in Korea; the second step is to estimate the magnitude of star power. The appearance of a star actor increases the probability of a hit or success by 15–19% and star power is higher than a director power. A domestic award is associated with positive performance. We find that the top 15 players among 68 actors and actresses significantly impacts on the success of movies.     

COVID-19 fatalities and internal conflict: Does government economic support matter?

This study examines the association between COVID-19 mortality rates and internal conflict and investigates the possible moderating role of government economic support during the pandemic years of 2020 and 2021. Our main hypothesis suggests that countries with lower levels of government economic support are more likely to experience a positive correlation between higher COVID-19 mortality rates and the emergence of internal conflict. Using cross-country data from over 100 countries and controlling for various factors that may influence internal conflict, our analysis provides some support for this hypothesis. The results suggest a possible moderating role for government economic support, with the evidence indicating a weakening or elimination of the association between COVID-19 mortality rates and internal conflict when government economic support is adequate. However, the moderating effect of government economic support is not always significant, and caution is needed when interpreting the results. Our analysis also highlights the potential risks associated with low levels of government economic support during the pandemic. Specifically, we find that in countries where the government's macro-financial package in response to the pandemic is less than approximately 25% of GDP, there is a possible risk of growth in civil disorder resulting from increased COVID-19 deaths per million.     

On the impact of inflation on output growth: Does the level of inflation matter?

This paper investigates the growth effects of inflation on a wide sample of countries, including both industrialized and emerging economies. Relying upon the estimation of smooth transition and dynamic GMM models for panel data, our findings offer strong evidence that inflation non-linearly impacts economic growth. More specifically, there exists a threshold beyond which inflation exerts a negative effect on growth, and below which it is growth enhancing for advanced countries.     

Does the stock market cause economic growth? Portuguese evidence of economic regime change

The relationship between stock market and economic growth is tested for Portugal (1993–2011), which is a small open economy dependent on bank financing. The relationship between economic growth and bank financing is also appraised. Using Vector Autoregressive (VAR) modeling, Granger causality, variance decomposition and impulse response function are discussed. The physical replacement of the currency, as a consequence of the integration in the European Monetary Union, proves to be an economic regime change. The effect of the subprime crisis was also proved. There is evidence of Granger bidirectional causality between the stock market and economic growth. Meanwhile, there was no evidence of causality running from bank financing to economic growth.     

Economic policy uncertainty in the US: Does it matter for the Euro area?

We investigate the effects of a US economic policy uncertainty shock on some Euro area macroeconomic aggregates via Structural VARs. We model the indicators of economic policy uncertainty recently developed by  Baker et al. (2013) jointly with the aggregate price indexes and alternative indicators of the business cycle for the two above indicated economic areas. According to our SVARs, a one standard deviation shock to US economic policy uncertainty leads to a statistically significant fall in the European industrial production and prices of −0.12% and −0.06%, respectively. The contribution of the US uncertainty shock on the European aggregates is shown to be quantitatively larger than the one exerted by an Euro area-specific uncertainty shock.     

Does timing of decisions in a mixed duopoly matter?

We determine the endogenous order of moves in a mixed price-setting duopoly. In contrast to the existing literature on mixed oligopolies we establish the payoff equivalence of the games with an exogenously given order of moves if the most plausible equilibrium is realized in the market. Hence, in this case it does not matter whether one becomes a leader or a follower. We also establish that replacing a private firm by a public firm in the standard Bertrand?CEdgeworth game with capacity constraints increases social welfare and that a pure-strategy equilibrium always exists.     

Does the role of observer countries in the regional trade agreement matter for intra-regional trade ?

This article investigates the effects of trade by observed economies on the intra-regional trade by South Asian Association for Regional Cooperation (SAARC) members using Poison pseudo maximum likelihood estimator (PPML) gravity models with panel data over the period 2008–2014. Eight SAARC members and eight observed countries, including the EU, are analysed in capturing the trade effect of observed economies on intra-regional trade in SAARC. This article provides an empirical measure of observers’ trade, FDI and Official development assistance (ODA) with SAARC if the exports and imports of observers to/from SAARC have positive or negative signs for intra-regional exports and imports. The results show that the exports and imports of observers to SAARC members have positive effects on bilateral exports among the members. The FDI of observers reduces the bilateral intra-imports in SAARC and ODA also has a negative effect on bilateral exports among the members. These results imply that the imports by SAARC members from observer countries increase intra-regional trade in the region. The FDI and ODA increase and decrease intra-regional trade in SAARC, respectively, implying that the policies for both FDI inflow from observers and efficient aid management are needed to increase regional welfare. The study also recommends that trade between SAARC members and its observers help to increase intra-regional trade in SAARC.
