In this paper we analyze the interaction of income and preference heterogeneity in a political economy framework. We ask whether the presence of preference heterogeneity (arising, for example, from different ethnic groups or geographic locations) affects the ability of the poor to extract...

We document the establishment and evolution of a cooperative norm among workers using evidence from a natural field experiment on a leading UK farm. Workers are paid according to a relative incentive scheme under which increasing individual effort raises a worker's own pay but imposes a negative...

In this paper we examine the main challenges in promoting an effective market economy. While the paper ranges widely across the spectrum of economic institutions and policies, the central theme is the importance of macroeconomic stability for economic growth in the medium and long run....

Interactions between economic development and financial development are studied by looking at the roles of financial institutions in selecting R&D projects (including both imitation and innovation). Financial development is regarded as the evolution of the financing regimes. The effectiveness of...

The concept of time discounting introduces weights on future goods to make these less valu- able. Famously, both the specic functional form of time discounting and its normative sta- tus are contested. To address these problems, this paper provides a measurement-theoretic framework of...

We develop new tests of the capital asset pricing model which are valid under the assumption that the distribution generating returns is elliptically symmetric; this assumption is necessary and sufficient for the validity of the CAPM. Our test is based on semiparametric efficient estimation...

A unifying theme in the literature on organizations such as public bureaucracies and private non-profits is the importance of missions, as opposed to profit, as an organizational goal. Such mission-oriented organizations are frequently staffed by motivated agents who subscribe to the mission....

We develop inference tools in a semiparametric regression model with missing response data. A semiparametric regression imputation estimator, a marginal average estimator and a (marginal) propensity score weighted estimator are defined. All the estimators are proved to be asymptotically normal,...

Cointegrated bivariate nonstationary time series are considered in fractional context, without allowance for deterministic trends. Both the observable series and the cointegrating error can be fractional processes. The familiar situation in which the respective integration orders are 1 and 0 is...

In a number of econometric models, rules of large-sample inference require a consistent estimate of f(0), where f (?) is the spectral density matrix of yt = ut?xt, for covariance stationary vectors ut, xt. Typically yt is allowed to have nonparametric autocorrelation, and smoothing is used in...
