In many markets, firms make their products complex through add-on features, thus making them difficult to evaluate and compare. Does this product obfuscation lure buyers into buying overpriced products, and if so, why does competition not eliminate this practice? More generally, under which...

We review the vast literature on social preferences by assessing what is known about their fundamental properties, their distribution in the broader population, and their consequences for important economic and political behaviors. We provide, in particular, an overview of the empirically...

Are initial competitive advantages self-reinforcing, so that markets exhibit an endogenous tendency to be dominated by only a few firms? Although this question is of great economic importance, no systematic empirical study has yet addressed it. Therefore, we examine experimentally whether firms...

Previous experimental work provides encouraging support for some of the central assumptions underlying Hart and Moore (2008)'s theory of contractual reference points. However, existing studies ignore realistic aspects of trading relationships such as informal agreements and expost renegotiation....

Economists have traditionally treated preferences as exogenously given. Preferences are assumed to be influenced by neither beliefs nor the constraints people face. As a consequence, changes in behaviour are explained exclusively in terms of changes in the set of feasible alternatives. Here we...

In many markets, firms make their products complex through add-ons, thus making them difficult to evaluate and compare. How does this product obfuscation affect competition, sellers' profits, and buyers' welfare? We study these questions in a competitive experimental market in which sellers have...

It is not common for an entire scholarly literature to be based on a fallacy, that is, 'on faulty reasoning; misleading or unsound argument'. The 'fiscal theory of the price level', recently re-developed by Woodford, Cochrane, Sims and others, is an example of a fatally flawed research...

The paper considers ways of avoiding a liquidity trap and ways of getting out of one. Unless lower short nominal interest rates are associated with significantly lower interest volatility, a lower average rate of inflation, which will be associated with lower expected nominal interest rates,...

The paper first reviews the budget identities of the fiscal and monetary authorities and the solvency constraint or present value budget-constraint of the consolidated public sector, for closed and open economies. It then discusses the new conventional wisdom concerning the fiscal roots of...

Debt neutrality is said to occur if, given a program for public spending on current goods and services over time, the real equilibrium of the economy (private consumption, investment, relative prices, etc.) is independent of the pattern of government borrowing and lump-sum taxation over time....
