Indices of voting power are intended to measure the a priori degree of in.uence that a voter or party can expect to have in framing legislation or passing motions. Commonly used measures include those proposed by Shapley and Shubik (1954), Banzhaf (1965) and Deegan and Packel (1978). This paper...

We examine a two-sector model characterized by monopoly provision in market 1 and perfect competition in market 2. We follow the set up in Martin (1999), but we consider the case where goods 1 and 2 can be either substitutes or complements. With this framework, we analyse the profit sacrifice...

The orthodox assumption in the banking literature is that capital requirements are a binding constraint on banking behaviour. This is in conflict with the empirical observation that banks hold a bu¤er of capital well in excess of the minimum requirements. This paper develops a model where...

This paper develops univariate and multivariate forecasting models for realized volatility in Australian stocks. We consider multivariate models with common features or common factors, and we suggest estimation procedures for approximate factor models that are robust to jumps when the...

We present theoretical and empirical results on consumption during an unemployment spell.

As is amply documented, there appears to be a large discrepancy between the marginal propensity to purchase food out of cash income and that out of food stamps. In this paper, we have examined both the formal and empirical bases of the claim that marginal welfare stigma explains this puzzling...

No distinction is made between the marginal social cost of public funds (MCF) and the shadow value of government revenue in the public finance literature. Their separate roles are demonstrated in this paper, where the MCF is used as a scaling coefficient to account for changes in tax...
