Distributed lag models are an important tool in modeling dynamic systems in economics. In the analysis of composite forms of such models, the component models are ordered in parallel (with the same independent variable) and/or in series (where the independent variable is also the dependent...

For a large class of demand and cost functions, we characterize the limit equilibrium set under Bertrand oligopoly when entry is exogenous. Unless average cost is constant, we find that the folk theorem of perfect competition necessarily fails. We also relate our results to those in Novshek and...

We examine if the folk theorem of perfect competition holds under Bertrand competition (when firms supply all demand), both when entry is exogenous, as well as when it is free. Inter alia, we also characterize the limit equilibrium sets.

Little is known about how children of high-income expatriate families, often from rich nations, adapt to temporary residence in a severely polluted city of the developing world. We use a six-year panel of 6,500 students at three international schools in a major city in north China to estimate...

This paper presents a forecasting exercise that assesses the predictive potential of a daily price index based on online prices. Prices are compiled using web scrapping services provided by the private company PriceStats in cooperation with a finance research corporation, State Street Global...

In Closing the Case on Closure in Cole's Model Randall Jackson and Moss Madden critique my solution to the time-lagged regional input-output model. My rebuttal demonstrates that they: i) interpret my model incorrectly, ii) are inconsistent in their own specification, and iii) make inapplicable...
