Finance and Wealth Inequality

Journal of International Money and Finance,

Abstract
Using a global sample, this paper investigates the determinants of wealth inequality capturing various economic, financial, political, institutional, and geographical indicators. Using instrumental variable Bayesian model averaging, it reveals that only a handful of indicators robustly matters and finance plays a key role. It reports that while financial depth increases wealth inequality, efficiency and access to finance reduce inequality. In addition, redistribution and education are associated with lower inequality whereas wars and openness to international trade contribute to greater wealth inequality.

Has Labor Income Become More Volatile? Evidence from International Industry-Level Data
Claudia M. Buch
German Economic Review,
Nr. 4,
2013
Abstract
Changes in labor market institutions and the increasing integration of the world economy may affect the volatility of capital and labor incomes. This article documents and analyzes changes in income volatility using data for 11 industrialized countries, 22 industries and 35 years (1970–2004). The article has four main findings. First, the unconditional volatility of labor income has declined in parallel to the decline in macroeconomic volatility. Second, the industry-specific, idiosyncratic component of labor income volatility has hardly changed. Third, cross-sectional heterogeneity is substantial. If anything, the labor incomes of high- and low-skilled workers have become more volatile relative to the volatility of capital incomes. Fourth, the volatility of labor income relative to the volatility of capital income declines in the labor share. Trade openness has no clear-cut impact.

The Term Structure of Sovereign Default Risk in EMU Member Countries and Its Determinants
Stefan Eichler, Dominik Maltritz
Journal of Banking and Finance,
Nr. 6,
2013
Abstract
We analyze the determinants of sovereign default risk of EMU member states using government bond yield spreads as risk indicators. We focus on default risk for different time spans indicated by spreads for different maturities. Using a panel framework we analyze whether there are different drivers of default risk for different maturities. We find that lower economic growth and larger openness increase default risk for all maturities. Higher indebtedness only increases short-term risk, whereas net lending, trade balance and interest rate costs only drive long-term default risk.

Regional Origins of Employment Volatility: Evidence from German States
Claudia M. Buch, M. Schlotter
Empirica,
Nr. 1,
2013
Abstract
Greater openness for trade can have positive welfare effects in terms of higher growth. But increased openness may also increase uncertainty through a higher volatility of employment. We use regional data from Germany to test whether openness for trade has an impact on volatility. We find a downward trend in the unconditional volatility of employment, paralleling patterns for output volatility. The conditional volatility of employment, measuring idiosyncratic developments across states, in contrast, has remained fairly unchanged. In contrast to evidence for the US, we do not find a significant link between employment volatility and trade openness.

Openness and Income Disparities: Does Trade Explain The 'Mezzogiorno' Effect?
Claudia M. Buch, P. Monti
Review of World Economics,
Nr. 4,
2010
Abstract
We use Italian regional data to answer the question whether trade affects within-country income differentials. In Italy, the more affluent Northern regions trade more with the rest of the world than the poorer ones in the Southern “Mezzogiorno” regions. Prima facie, there is a positive correlation between external trade and per capita income. Studying this relationship empirically requires taking into account the endogenous component of trade. We argue that panel cointegration models can complement instrumental variables techniques to account for the endogeneity of trade in a panel context. Both methods show a positive link between trade openness and the level of income per capita.

Openness and Growth: The Long Shadow of the Berlin Wall
Claudia M. Buch, Farid Toubal
Journal of Macroeconomics,
Nr. 3,
2009
Abstract
The question whether international openness causes higher domestic growth has been subject to intense discussions in the empirical growth literature. This paper addresses the issue in the context of the fall of the Berlin Wall in 1989. We analyze whether the slow convergence in per capita incomes between East and West Germany and the lower international openness of East Germany are linked. We address the endogeneity of openness by adapting the methodology proposed by Frankel and Romer (1999) to a panel framework. We instrument openness with time-invariant exogenous geographic variables and time-varying exogenous policy variables. We also distinguish the impact of different channels of integration. Our paper has three main findings. First, geographic variables have a significant impact on regional openness. Second, controlling for geography, East German states are less integrated into international markets along all dimensions of integration considered. Third, the degree of openness for trade has a positive impact on regional income per capita.

Does Export Openness Increase Firm-level Output Volatility?
Claudia M. Buch, Jörg Döpke, H. Strotmann
World Economy,
Nr. 4,
2009
Abstract
There is a widespread concern that increased trade may lead to increased instability and thus risk at the firm level. Greater export openness can indeed affect firm-level volatility by changing the exposure and the reaction of firms to macroeconomic developments. The net effect is ambiguous from a theoretical point of view. This paper provides firm-level evidence on the link between openness and volatility. Using comprehensive data on more than 21,000 German manufacturing firms for the period 1980–2001, we analyse the evolution of firm-level output volatility and the link between volatility and export openness. Our paper has three main findings. First, firm-level output volatility is significantly higher than the level of aggregate volatility, but it displays similar patterns. Second, increased export openness lowers firm-level output volatility. This effect is primarily driven by variations along the extensive margin, i.e. by the distinction between exporters and non-exporters. Variations along the intensive margin, i.e. the volume of exports, tend to have a dampening impact on volatility as well. Third, small firms are more volatile than large firms.

Trade's Impact on the Labor Share: Evidence from German and Italian Regions
Claudia M. Buch
IAW Discussion Paper No. 46,
2008
Abstract
Has the labor share declined? And what is the impact of international trade? These
questions are not only relevant in an international context they also matter for
understanding the regional distribution of incomes in a given country. In this
paper, we study two regions with trade exposures that differ from the rest of the
country, and which display distinct changes in the labor share. East German and
Southern Italian regions have a degree of international openness which is below
the countries’ averages. At the same time, there has been a more pronounced
decline in the labor share in East Germany than in West Germany. In Southern
Italy, the labor share has increased in recent years. We show that increased trade
openness is not the main culprit behind changing labor shares.

The Great Risk Shift? Income Volatility in an International Perspective
Claudia M. Buch
CESifo Working Paper No. 2465,
2008
Abstract
Weakening bargaining power of unions and the increasing integration of the world economy may affect the volatility of capital and labor incomes. This paper documents and explains changes in income volatility. Using a theoretical framework which builds distribution risk into a real business cycle model, hypotheses on the determinants of the relative volatility of capital and labor are derived. The model is tested using industry-level data. The data cover 11 industrialized countries, 22 manufacturing and services industries, and a maximum of 35 years. The paper has four main findings. First, the unconditional volatility of labor and capital incomes has declined, reflecting the decline in macroeconomic volatility. Second, the idiosyncratic component of income volatility has hardly changed over time. Third, crosssectional heterogeneity in the evolution of relative income volatilities is substantial. If anything, the labor incomes of high- and low-skilled workers have become more volatile in relative terms. Fourth, income volatility is related to variables measuring the bargaining power of workers. Trade openness has no significant impact.
