A strategy to convert quotas to tariffs is to auction the quota rights and use the realized auction prices as guides to setting tariffs. In the 1980s, New Zealand employed auctions to allocate quota licenses. We analyze the relationship between tariff-equivalents and auction prices for auctions with resale. Using panel data from New Zealand’s quota license auctions, we estimate the expected val...

We examine the impact of a large number of Japanese government-sponsored research consortia on the research productivity of participating firms by measuring their patenting in the targeted technologies before, during, and after participation. Consistent with the predictions of the theoretical literature on research consortia, we find consortium outcomes are positively associated with the level ...

The paper contributes to the measurement of poverty and vulnerability in three ways. First, we propose a new approach to separating poverty into chronic and transient components. Second, we provide corrections for the statistical biases introduced when using a small number of periods to estimate the importance of vulnerability and transient poverty. Third, we apply these tools to the measuremen...

In this paper, we present an alternative root-n consistent estimator for panel data fixed-effects binary choice models. The proposed estimator relaxes one of the key conditions that are required for the consistency of the estimator proposed in Honoré and Lewbel (2002), and is shown to be consistent and asymptotically normally distributed under some sufficient conditions. An easy to compute cons...

Demsetz and Lehn (1985), Morck, Shleifer, and Vishny (1988), and McConnell and Servaes (1990) report different empirical findings regarding ownership structure and corporate profitability. In this paper, we re-estimate the relation between management ownership and firm's value after controlling for the history of management ownership as well as inter-firm differences using panel data. Further, ...

The price of oil, which is typically thought to have a strong effect on the Russian economy, was also quite ...
