The purpose of this paper is to develop a model that integrates inventory and labor decisions. We extend a model of inventory behavior to include a detailed specification of the role of labor input in the production process and of the costs associated with it. In particular, we distinguish...

This paper studies the impact of credit rating agency (CRA) downgrade announcements on the value of the Euro and the yields of French, Italian, German and Spanish long-term sovereign bonds during the culmination of the Eurozone debt crisis in 2011-2012. The employed GARCH models show that CRA...

Past observational studies of the associations of area-level/contextual social capital with health have revealed conflicting findings. However, interpreting this rapidly growing literature is difficult because estimates using conventional regression are prone to major sources of bias including...

We review the Stata statistical package and evaluate its suitability for applied research.

We empirically examine the influence of risk on firms' capital structure adjustments. The process of adjustment is asymmetric and depends on the type of risk, its magnitude, the firm's actual leverage with respect to its target, and its financial status. We show that firms with financial...

We use single equation and simultaneous instrumental variable models to explore if individuals smoke during times of stress (i.e., motivation effect) and if they are successful in self-medicating short-term stress (i.e., self-medication effect). Short-term stress is a powerful motivator of...

We evaluate alternative models of the volatility of commodity futures prices based on high-frequency intraday data from the crude oil futures markets for the October 2001-December 2012 period. These models are implemented with a simple GMM estimator that matches sample moments of the realized...

We examine the effect of scheduled macroeconomic announcements made by China on world financial and commodity futures markets. All announcements related to Chinese manufacturing and industrial output move stock markets, energy and industrial commodities as well as commodity currencies. News...

This paper empirically examines the role of diversification in export markets on firm-level R&D activities. We show that geographical sales diversification across different regions of the world induces UK firms to increase their R&D expenditures, as firms must innovate and develop new products...

By 1989 the Michigan Panel Study on Income Dynamics (PSID) had experienced approximately 50 percent sample loss from cumulative attrition from its initial 1968 membership. We study the effect of this attrition on the unconditional distributions of several socioeconomic variables and on the...
