From an empirical point of view, it is difficult to distinguish between fluctuations provoked by random shocks and endogenous fluctuations determined by the nonlinear nature of the relation between economic aggregates. For this purpose, chaos tests are developed to investigate the chaotic phenomena of basic features: nonlinearity, fractal attractor, and sensitivity to initial conditions. The ap...

This paper models the determinants of exporting (both in terms of export propensity and export intensity), with a particular emphasis on the importance of absorptive capacity and the endogenous link between exporting and undertaking R&D. Based on a merged dataset of the 2001 Community Innovation Survey and the 2000 Annual Respondents Database for the UK, our results suggest that establishment s...

We examine investment behavior when firms face costs in the access to external funds. We find that despite the existence of liquidity constraints, standard investment regressions predict that cash flow is an important determinant of investment only if one ignores q. Conversely, we also obtain significant cash flow effects even in the absence of financial frictions. These findings provide suppor...

Both financing and risk management involve promises to pay that need to be collateralized, resulting in a financing versus risk management trade-off. We study this trade-off in a dynamic model of commodity price risk management and show that risk management is limited and that more financially constrained firms hedge less or not at all. We show that these predictions are consistent with the evi...

Recent work in the real options approach to investment has argued that firms face significant opportunity costs when entry costs are largely irreversible, and these costs equal the value of an option to defer investment. This study seeks to examine empirically these claims by investigating the interactive effects of uncertainty and irreversibility on the likelihood of entry into new business by...

Emerging markets exhibit high returns to capital, the ‘Lucas Paradox,’ alongside volatile growth rate regimes. We investigate the role of long-run risks, i.e., risk due to fluctuations in economic growth rates, in leading to return differentials across countries. We take the perspective of a US investor and outline an empirical strategy to identify risky growth shocks and quantify their implica...
