The Unassuming Economist

From a dissertation paper by Sebastian Stephan Leue:

“The three economic drivers of globalization are the free flow of labor, goods, and capital. Together they have shaped three waves of globalization over the last 200 years. This dissertation encompasses all three waves of globalization between 1877 and 2020, and it investigates its three main economic drivers: International migration, trade, and investment. Every chapter brings forward new insights to each of the three drivers separately. Chapters 1 and 2 provide novel and causal solutions to open questions to our fundamental understanding of migration and international trade, by exploiting two natural experiments over the long run. Chapter 1 contributes to the fundamental understanding of the causal effect of income on migration in the context of economic development. Chapter 2 revisits the distance puzzle in international trade. Chapter 3 examines the role of politics in Chinese exports of critical medical goods during the COVID-19 pandemic. Finally, Chapter 4 evaluates the economic impact of the annual meeting of the World Economic Forum in Davos, Switzerland. This dissertation further aims to provide new perspectives to all three economic drivers through causal empirical research. It introduces four spatially and temporally granular datasets that provide the foundation of novel insights to the globalization nexus through quasi-experimental methods.”

“This study examines the impact of macroeconomic fundamentals on the House Prices in twelve selected African countries, using time series data spanning from 2000 to 2020. The study employs Westerlund Error Correction Based Panel Cointegration test to examine the impact of some domestic (RINTR, RGDPGR, EXR, SP) and foreign (USRINTR, WRGDPGR, WOP) macroeconomic fundamentals on House Price Index. Findings from the study reveal that there is a long-run relationship between the House Price Index and The macroeconomic fundamentals. The research work also confirms that foreign macroeconomic fundamentals are better determinants of House Price than the domestic macroeconomic fundamentals in the selected African countries during the period under review.”

“Economic growth is often associated with welfare gains through job creation. However, the number and quality of new job opportunities created in a growing economy vary across countries and sectors, due in great part to changes in labor productivity. This paper provides estimates of country and sector-specific GDP-employment elasticities based on data from the past two decades, including an evaluation of the predictive power among alternative methodological approaches. The results show that employment elasticities of growth vary significantly across countries and sectors, but are in most cases below 1.0, implying that employment grows less than GDP due to increasing productivity. Across sectors, agriculture has mostly lower elasticity values, becoming negative for more than one-third of developing countries. In addition, increases in labor productivity are associated with reductions in informal employment. These empirical results are in line with the implications of a theoretical model about the relationship between GDP growth, job creation, and labor productivity in economies with varying levels of productivity and informality.”

“This paper uses the dynamic connectedness framework to investigate the interrelationship between the decomposed oil supply, demand and risk shocks that Ready (2018) developed and the stock market returns of emerging market economies. For this purpose, we use daily data from 11 October 2001 to 5 April 2021. Novel empirical methodologies, including wavelet quantile correlation (WQC), cross-quantilogram analysis, nonparametric causality-in-quantile approaches, contemporaneous R² connectedness approach and generalized R² connectedness approaches, are employed. The results show that oil price fluctuations significantly impact the economic performance of emerging market economies, reflecting historical events. Demand price shocks are regarded as net transmitters within the system, whereas supply and risk price shocks are net receivers of spillovers. Concurrently, our findings indicate a considerable degree of dynamic connectedness among the stock markets of emerging market economies. In particular, the stock markets of Brazil, Mexico, and Argentina have been identified as net transmitters of spillovers. In contrast, the stock markets of Turkey, South Korea, Malaysia, Indonesia and India are classified as net receivers of spillovers. Furthermore, we examine and document the advantages of diversified portfolios that include all sector indices, including oil price shocks and emerging market economy stock markets, in terms of portfolio performance. The insights offered here are valuable for investors and policymakers striving to enhance their strategic approaches in today’s interconnected global financial context. The results show that oil price fluctuations significantly impact the economic performance of emerging market economies and reflect historical events. Demand shocks affecting the stock market indices of Brazil, Argentina and Mexico tend to act as net spillover transmitters. In contrast, supply shocks affecting the stock market indices of Indonesia, South Korea, India, Turkey and Malaysia mainly act as net spillover receivers. Net pairwise interconnectedness analysis reveals that, except for crisis periods, interactions between financial markets or macroeconomic indicators are evenly distributed. Thus, systemic risk is lower, and markets act independently. Empirical findings obtained using WQC generally show the presence of negative correlations at long-time scales and low quantiles, which is considered an indicator of the safe-haven feature associated with the asset in question. The hedge feature is observed to be evident only at long time scales. The results of the cross-quantilogram analysis show mixed evidence of correlation in all stock indices, especially in the weekly lag structure, compared to daily and monthly lags. Finally, non-parametric Granger causality test results show that stock returns are insensitive to oil price fluctuations, making these markets attractive for investors seeking diversification strategies. These findings provide valuable recommendations for investors seeking sustainable equities in a volatile oil market.”

From a paper by Akhilesh Kumar Sharma, and Sushil Kumar Rai:

“The empirical results from the applied models do not confirm an inverse relationship between output growth and the unemployment rate with an unexpected positive sign of Okun’s coefficient. The evidence of preference for more capital-intensive techniques in the Indian economy is also strongly supported by the results of the expanded form of Okun’s law with a statistically significant positive coefficient of GDP and labour productivity.”
