This paper provides the first evidence that value-added education accountability schemes induce dynamic distortions. Extending earlier dynamic moral hazard models, I propose a new test for ratchet effects, showing that classroom inputs are distorted less when schools face a shorter horizon over...

Using firm-level data this paper analyzes the transformation of India's economic structure following the implementation of economic reforms. The focus of the study is on publicly-listed and unlisted firms in manufacturing and services industries. Detailed balance sheet and ownership information...

It is now well known that the Sharpe ratio and other related reward-to-risk measures may be manipulated with option-like strategies. In this paper we derive the general conditions for achieving the maximum expected Sharpe ratio. We derive static rules for achieving the maximum Sharpe ratio with...

Industry cost and demand conditions can vary across countries leading to differences in industry market structure, including the distribution of output and productivity across firms and the magnitude of entry and exit flows. It has been argued that despite many outward similarities, two of the...

We decompose the cross-sectional variance of firms' book-to-market ratios using both a long U.S. panel and a shorter international panel. In contrast to typical aggregate time-series results, transitory cross-sectional variation in expected 15-year stock returns causes only a relatively small...

Financial variables such as cash flow and cash stocks are robust and quantitatively important explanatory variables for investment at the firm-level. A large body of recent empirical work attributes these findings to capital market imperfections. This interpretation is controversial, however,...

This paper documents a new empirical regularity: teacher value-added increases within-teacher when accountability incentives are strengthened. That finding motivates a strategy to separate value-added into incentive-varying teacher effort and incentive-invariant teacher ability, combining rich...

This paper studies the economics behind the investment in information technologies (IT) by U.S. commercial banks in the past decade. By linking banks' IT spending to their lending technologies, we analyze the distinctive natures of banks' dealings with information across various lending...

Databases play a central role in evidence-based innovations in business, economics, social, and health sciences. In modern business and society, there are rapidly growing demands for constructing analytically valid databases that also are secure and protect sensitive information in order to meet...

We investigate how firms manage financial default risk (on debt) and operational default risk (on delivery obligations). Financially constrained firms reduce operational hedging through inventory and supply chain in favor of cash holdings. Our model predicts that firms' markup increases with...
