We provide a result for non-emptiness of the core in NTU games. We use a payoffs-dependent balancedness condition, based on transfer rate mappings. Going beyond the non-emptiness of standard core, existence of some refined solution is proved, including specific core allocations and...

In competitive economies with private firm ownership, incomplete markets, and firm shareholders changing over time, several firm objectives have been proposed. Some are useful to understand efficiency of equilibria, and others are explicitly consistent with majority shareholder control or...

The paper examines a new possibility of output gaps in an economy without any rigidity. The driving force behind the new possibility is non-cooperative behavior of consumers. The paper shows that there is a possibility that when a fundamental shock hits an economy this non- cooperative nature...

We use CEX repeated cross-section data on consumption and income, to evaluate the nature of increased income inequality in the 1980s and 90s. We decompose unexpected changes in family income into transitory and permanent, and idiosyncratic and aggregate components, and estimate the contribution...

The current literature offers two views on the nature of the income process. According to the first view, which we call the “restricted income profiles” (RIP) model (MaCurdy, 1982), individuals are subject to large and very persistent shocks, while facing similar life-cycle income profiles...

This paper studies competitive equilibria of a production economy with aggregate productivity shocks and with a continuum of consumers subject to borrowing constraints and individual labor endowment shocks. The dynamic economy is described in terms of sequences of aggregate distributions. The...

Previous papers on time-inconsistent procrastination assume projects are completed once begun. We develop a model in which a person chooses whether and when to complete each stage of a long-term project. In addition to procrastination in starting a project, a naive person might undertake costly...

This paper presents a model of smoking choice in which rationality is bounded by limitations in intertemporal computational abilities. The model is applied to the youth decision to initiate smoking. Lifetime smoking paths of representative smokers indicate that youths may experience a reduction...
