We discuss a problem concerning Dasgupta, Hammond, and Maskin''s (1979) definition of a rich domain and a very well-known result they established for these domains: on rich domains, if a social choice function is implementable in Nash strategies, then it is truthfully implementable in dominant...

The Netherlands is well known for its high employment growth and corresponding low unemployment rate. At various occasions the so-called Dutch miracle has been applauded, together with the underlying ‘Polder model’. A feature that initially was less recognised in the international debate,...

This paper is concerned with polynomial time approximations schemes for the generalized geometric problems with geographic clustering. We illustrate the approach on the generalized traveling salesman problem which is also known as Group-TSP or TSP with neighborhoods. We prove that under the...

This paper studies and assesses the impact of G3 Central Bank interventions on the DEM/USD exchange rate properties using daily realized moments of exchange rate returns (obtained from intraday data) for the period 1989-2001. Event studies in terms of the realized moments for the intervention...

In this paper we present a new iterative auction, the bisection auction, that can be used for the sale of a single indivisable object. We will show that the bisection auction is computationally more efficient than the classical English auction while it still preserves all characteristics the...

The growth of Internet technology and electronic commerce has not been matched by theoretically-guided social science research. Clear and well designed consumer research is needed to describe, explain, and predict what will happen to this changing landscape. The primary purpose of this study is...

In this paper we consider the p-coverage problem on the real line. We first give a detailed description of an algorithm to solve the coverage problem without the upper bound p on the number of open facilities. Then we analyze how the structure of the optimal solution changes if the setup costs...

This paper proposes a new duration-based backtesting procedure for VaR forecasts. The GMM test framework proposed by Bontemps (2006) to test for the distributional assumption (i.e., the geometric distribution) is applied to the case of VaR forecast validity. Using simple J-statistics based on...

In voting problems where agents have well behaved (Lipschitz continuous) utility functions on a multidimensional space of alternatives, a voting rule is threshold strategy-proof if any agent can only obtain a limited utility gain by not voting for a most preferred alternative,given that the...
