Many historians now reject quantitative methods as inappropriate to understanding past societies. It is argued here, however, that no sharp distinction between qualitative and quantitative concepts can be drawn, as almost any concept used to describe a past society is implicitly quantitative....

Most of the voting models restrict themselves to the analysis of symmetric equilibria, i.e. equilibria in which ‘similar’ voters make ‘similar’ voting decisions. In this paper we investigate this assumption under costly plurality voting. In any pure strategy equilibrium, if two active...

Peering decisions between Internet Service Providers contain substantial non-measurable aspects requiring trust and informal cooperation among peering partners. We study whether spatial agglomeration is observed between Internet peers. Our empirical analysis of the bilateral peering decisions at...

Many constitutions specify procedures that allow critical decisions to be made with a different rule from day-to-day decisions. We propose a theory of constitutional rules that explains why. The theory is based on the assumption that the type of decision can be observed, but not verified. We...

In this paper we study concentration in the European Internet upstream access market. Measurement of market concentration depends on correctly defining the market, but this is not always possible as Antitrust authorities often lack reliable pricing and traffic data. We present an alternative...

The same fuels are taxed at widely different rates in different countries while different fuels are taxed at widely different rates within and across countries. Coal, oil and gas are all used to generate electricity, but are subject to very different tax or subsidy regimes. This paper considers...

Central bank independence and transparency have become best practice in monetary policy. This paper cautions that transparency about economic information may not be beneficial in the absence of central bank independence. The reason is that it reduces monetary uncertainty, which could make the...

This paper studies a game theoretic model where agents choose between two updating rules to predict a future endogenous variable. Agents rationally choose between these predictors based on relative performance. Conditions for evolutionary stability and stability under learning are found for the...

We study the properties of generalized stochastic gradient (GSG) learning in forwardlooking models. We examine how the conditions for stability of standard stochastic gradient (SG) learning both di1er from and are related to E-stability, which governs stability under least squares learning. SG...

The Low Pay Commission is the institution created in 1997 to introduce Britain’s first National Minimum Wage. The paper places the Commission in historical perspective and provides a summary assessment of the initial impact of the Minimum Wage. It describes and analyses the development of the...
