We propose a structural econometric evaluation for auctions with discrete increments. Although very common in practice, this kind of mechanism raises many theoretical difficulties. First, there are no closed form equilibriumstrategies. Thus the econometrician cannot rely on a single formula to...

We propose a test for spatial correlation in Probit models that is a joint test for exclusion of spatially lagged-dependent variables and absence of spatial-error correlation. We give a maximum-likelihood justification for the test but use a simulations approach rather than relying on its...

Analyses the influence of value judgements in the mechanics of testing econometric theories against empirical data. The orthodox view of mainstream, positive economics is that value judgements play no part in the above process. Contests this view; defines value judgements and shows the orthodox...
