The invisibility of information precludes a direct test of attention allocation theories. To surmount this obstacle, we develop a model that uses an observable variable – the state of the business cycle – to predict attention allocation. Attention allocation, in turn, predicts aggregate investment...

We propose a new way of estimating a stochastic frontier model with time-varying firm effects. By means of nonparametric smoothing of categorical data we allow for completely unspecified time-varying firm effects. Furthermore it is well established that smoothing of cell probabilities of sparse...

We propose that the takeover market mitigates agency conflicts by creating acquisition opportunities for successful managers, allowing shareholders to reduce monetary incentives. As a consequence, shareholders commit to finance not ony profitable but also some unprofitable takeovers. While board...

This research examines the economic origins of Islam. It empirically demonstrates that Muslim countries, virtual countries and ethnic groups, exhibit highly unequal regional agricultural endowments. This particular type of geography (i) determined the economic aspects of the religious doctrine upon...

This paper aims to identifiy heterogeneous causal effects of an ordered discrete variable chosen by individuals, without relying on parametric assumptions. The proposed nonparametric restrictions have set identifying power of the value of the nonseparable structural function. When applied to an "...

Within the penalized model selection (PMS) approach the selected model is defined by minimization of penalized empirical risk. Such procedures enjoy nice algorithmic properties especially if both the empirical risk and the penalty function are convex functions of the parameter. A number of ``...

Aggregation of information provided by experts is usually conceived as independent from the decision maker's preferences. We argue that this entails a substantial loss, insofar as it precludes the possibility to take into account simultaneously the decision maker's attitude towards disensus among...

Maternal deaths accounted for over 15% of all deaths of women in prime age years until the mid-1930s in the U.S. Starting in 1936, the maternal mortality rate dropped dramatically, reaching modern levels by the early 1950s. The female-male differential in life expectancy at age twenty rose from one...
