This paper models individual choices of social groups and the formation of group identity, and examines the conditions with which the group identity reinforces the productivity of individuals. A social group is defined as a network that provides with a market for interactions to its members....

In this paper we study hedonic games where each player views every other player either as a friend or as an enemy. Two simple priority criteria for comparison of coalitions are suggested, and the corresponding preference restrictions based on appreciation of friends and aversion to enemies are...

We examine the formation of networks among a set of players whose payoffs depend on the structure of the network. We focus on games where players may promise or demand transfer payments when forming links. If players may only make such transfers on the links they are directly involved with, then...

This paper assesses the effects of agency costs and asymmetric information in credit markets. Asymmetric information and agency costs occur whenever lenders delegate control over resources to borrowers, leading to adverse selection, moral hazard and monitoring costs because of the inability to...

USAGE is a 500 industry dynamic computable general equilibrium model of the US economy being developed at Monash University in collaboration with the US International Trade Commission. In common with the MONASH model of Australia, USAGE is designed for four modes of analysis: Historical, where...

In this paper, we propose the use of bootstrapping methods to obtain correct critical values for dating breaks. Following the procedure proposed in Banerjee, Lazarova and Urga (1998), we consider the case of estimating a system with two or more marginal processes and a conditional process....

In this paper, we consider testing marginal distributional assumptions. Special cases that we consider are the Pearson's family like the Gaussian, Student, Gamma, Beta and uniform distributions. The test statistics we consider are based on the first moment conditions derived by Hansen and...

In this paper it is shown that "classical" tests can become asymptotically inadmissible (i.e. we show that there exist uniformly better tests) if the information matrix becomes stochastic: A typical example is the augmented Dickey-Fuller test for unit roots (in case of no deterministic trend. We...

The notion of cointegration was developed by Engle and Granger (1987), and since then has been considered important in the recent development of time series econometrics. Many statistical methods have been developed for the analysis of the cointegrated systems, and several methods of estimating...

A correctly specified time series model can be used to transform the data set to obtain an i.i.d. sequence of random variables, assuming that the true parameter values are known. In reality, however, one only has an estimated model and must therefore address the sampling error associated with...
