This study examines the influence of country and industry factors on the cross-sectional variance and correlation structure of returns. I use new data on emerging markets’ stocks obtained from the Emerging Markets Data Base. I find that emerging markets’ returns are mainly driven by country factors, as it was shown previously in studies for mature markets, and that cross-market correlation is n...

While most research on hedging has focused on foreign currency exposures, analysis of jet fuel price exposure in the airline industry and the effects of both financial and operational hedging on this exposure provides valuable insights into risk management. Exposure and hedging in the airline industry is relatively straightforward compared to foreign exchange hedging by multinationals. We inves...

There is a general interest in using this type of steel in the automotive industry due to its unique material properties such as super toughness and super ductility, although its chemical properties also play a vital role. It has a high content of Mn (more than 25%) and about 3% Si ...

Since both events were almost certainly caused by the entry and market penetration of (largely) foreign owned car producers, this stylized fact raises interesting qu...

Using a simple two-firm, two-period model, we analyze for a developing economy the process of entrepreneurial entry, that is, entry by new firms into an industry that did not previously exist in that country, focusing on the choice between formal and informal status. Thus we explore issues such as how informality may enable an entrepreneur to test the profitability of an industry without incurr...

INTRA-INDUSTRY TRADE AS AN INDICATOR OF LABOR MARKET ADJUSTMENT A growing body of recent empirical research uses measures of change in intra-industry trade as indicators of labor market adjustment. In this paper, we argue that the theoretical foundations for this work are problematic. To make this argument we develop a simple model with both interand intra-industry trade and adjustment. We defi...

In this study we analyze the evolution of operating cost inefficiency for the English and Welsh water industry over the period 1995-2001 by estimating an heteroskedastic stochastic variable cost frontier. The main aim of this paper is to provide an overall picture of the industry cost inefficiency, as we consider both the water and sewerage companies and the smaller water only companies. The ma...

We find that: i) This restriction is strongly rejected by the data. ii) Many industry betas are negative, while almost all country betas...
