The paper provides a complete characterization of the turnpike property of optimal paths in the (reduced form) aggregative model of intertemporal allocation. The characterization allows one to identify precisely the bifurcation point between globally stable and cyclical long-run optimal...

Data dependent bandwidth choices for zero frequency spectral density estimators of a time series are shown to be an important source of nonmonotonic power when testing for a shift in mean. It is shown that if the spectral density is estimated under the null hypothesis of a stable mean using a...

Capital allocation decisions are made on the basis of an assessment of creditworthiness. Default is a rare event for most segments of a bank's portfolio and data information can be minimal. Inference about default rates is essential for efficient capital allocation, for risk management and for...

We study a one-sector stochastic optimal growth model, where the utility function is iso-elastic and the production function is of the Cobb-Douglas form. Production is affected by a multiplicative shock taking one of two values. We provide sufficient conditions on the parameters of the model...

Employment brings access to many types of benefits, both financial and psychological. Besides a wage, one can earn a sense of pride or a feeling of connection with her society or fellow employees. How attached one is to the labor market is not an issue that the usual unemployment rate deals...

In this paper, we offer an instance of (topologically) chaotic optimal behavior in a twosector model with irreversible investment, originally formulated by Robinson, Solow and Srinivasan. Our result follows from the theory of turbulence in non-linear dynamical systems, and relies only on the...

Kernel smoothing techniques have attracted much attention and some notoriety in recent years. The attention is well deserved as kernel methods free researchers from having to impose rigid parametric structure on their data. The notoriety arises from the fact that the amount of smoothing (i.e.,...

This paper demonstrates how our sense of identity can emerge out of mere markers of social distinction that may have no innate significance, but, nevertheless, spread to various aspects of our lives and be the root of conflict. The basis of such conflicts could arise from the use of race to form...

Many countries have legislation which make it costly for firms to dismiss or retrench workers. In the case of India, the Industrial Disputes Act, 1947, requires firms that employ 50 or more workers to pay a compensation to any worker who is to be retrenched. This paper builds a theoretical model...
