Simple exchange rate models based on economic fundamentals were shown to have a difficulty in beating the random walk when predicting the exchange rates out of sample in the modern floating era. Using methods from machine learning -- sequential adaptive ridge regression -- that prevent...

High frequency arbitrage opportunities arise when the price of one asset follows, with a lag, changes in the value of another related asset due to information arrival. These opportunities are toxic because they expose liquidity suppliers to the risk of being picked off by arbitrageurs. Hence,...

The authors provide possibility results on the aggregation of beliefs and tastes for Monotone, Bernoullian and Archimedian preferences of Cerreia-Vioglio, Ghirardato, Maccheroni, Marinacci, and Siniscalchi (2011). The authors propose a new axiom, Unambiguous Pareto Dominance, which requires that...

The paper aims to contribute to the longstanding technology-push vs. demand-pull debate and to the literature on renewable energy diffusion and renewable energy policy assessment. The authors argue that in addition to the traditional push-pull dichotomy, the drivers of technological change must...

This paper shows that collateral constraints restrict firm entry and post-entry growth, even in the long-run. The authors' empirical strategy uses French administrative data and exploits cross-sectional variation in local house-price appreciation as shocks to the value of collateral available to...

The authors examine the effect of a hospital's objective (i.e., non-profit versus for-profit) in hospital markets for elective care. Using game-theoretic analysis and queueing models to capture the operational performance of hospitals, they compare the equilibrium behavior of three market...

This paper investigates the determinants of value and growth investing in a large administrative panel of Swedish residents over the 1999-2007 period. The authors document strong relationships between a household's portfolio tilt and the household's financial and demographic characteristics....

Confronted by increasingly tight budgets and a broad range of alternative options, policy makers need empirical methods to evaluate the effectiveness of policies aimed at supporting the diffusion of renewable energy sources (RES). Rigorous empirical studies of renewable energy policy...

The authors use large reductions of import tariffs to examine how incumbent firms modify investment when the threat of entry by foreign rivals intensifies. Incumbents reduce investment by 7.2% of capital in response to higher entry threat. This effect is robust, pervasive, and likely causal....

Political activism positively affects firm innovation. Firms that support more politicians, politicians on Congressional committees with jurisdictional authority over the firms’ industries and politicians who join those committees innovate more. The authors employ instrumental variables...
