GDP is a closely watched indicator of the current health of the economy and an important tool of economic policy. It has been called one of the great inventions of the 20th Century. It is not, however, a persuasive indicator of individual wellbeing or economic progress. There have been calls to...

Ever since the early days of National Income accounting we can observe periodic surges of demands to fix the measurement of GDP to better reflect progress, welfare or even happiness. In recent years even Presidents and Prime Ministers in Europe have joined the chorus of the discontent. In this...

The welfare contributions of the digital economy, characterized by the proliferation of new and free goods, are not well-measured in our current national accounts. We derive explicit terms for the welfare contributions of these goods and introduce a new metric, GDP-B which quantifies their...

This article investigates the purpose and workings of EU competition law and policy: how does the protection of competition promote welfare? It scrutinizes the claim that sustainable consumption and production (SCP) requires flexible rather than strict enforcement of Article 101 TFEU. Flexible...

The paper provides a rigorous derivation of the "welfare triangle approximation" (WTA), which is at the center of cost benefit analysis. The result is generalized by showing that the WTA is one of two dual expressions, one of which approximates the change in real consumption, the other the...

We show that the entry of a second firm in a horizontally differentiated market (ala Hotelling) may harm consumers as prices increase and consumer's surplus possibly decrease. We first derive the price and the consumer's surplus of a monopoly which is located at the center of the market. When a...

I examine the circumstances under which a sophisticated time-inconsistent decisionmaker (i) will not or (ii) need not severely miscoordinate her behavior across time, in the sense of following a course of action which fails to be Pareto-optimal for the sequence of temporal selves of the...
