Optimistic irrationality and overbidding in private value auctions

Bidding one’s value in a second-price, private-value auction is a weakly dominant solution (Vickrey in J Finance 16(1):8–37, 1961), but repeated experimental studies find more overbidding than underbidding. We propose a model of optimistically irrational bidders who understand that there are possible gains and losses associated with higher bids but who may overestimate the additional probability of winning and/or underestimate the potential losses when bidding above value. These bidders may fail to discover the dominant strategy—despite the fact that the dominant strategy only requires rationality from bidders—but respond in a common sense way to out-of-equilibrium outcomes. By varying the monetary consequences of losing money in experimental auctions we observe more overbidding when the cost to losing money is low, and less overbidding when the cost is high. Our findings lend themselves to models in which less than fully rational bidders respond systematically to out-of-equilibrium incentives, and we find that our model better fits the effects of our manipulations than most of the existing models we consider.     

Inflation perceptions and expectations in Sweden – Are media reports the missing link?

We analyze the interrelation between consumers' quantitative inflation perceptions and expectations as well as actual inflation rates in Sweden. The role of media reports about inflation is emphasized. Structural vector error correction models show stable cointegration between actual, perceived and expected inflation. Impulse responses and forecast error variance decompositions suggest strong interaction between perceived and expected inflation, with a lesser role for actual inflation. Media effects are generally small, but imply an asymmetric reaction of inflation expectations and perceptions to news on increasing vs. decreasing inflation. Thus, to anchor inflation expectations, central banks should explore better communication channels to inform consumers about actual inflation.     

New Keynesian dynamics in a low interest rate environment

Recent research has found that the dynamic properties of the New Keynesian model are unorthodox when the nominal interest rate is zero. Improvements in technology and reductions in the labor tax rate lower economic activity and the size of the government purchase output multiplier is very large. This paper provides evidence that these results are not empirically relevant. We show that a prototypical New Keynesian model fit to Japanese data exhibits orthodox dynamics during Japan's episode with zero interest rates. We then demonstrate that this specification is more consistent with outcomes in Japan than alternative specifications that have unorthodox properties.     

The value of information in monotone decision problems

We study the information preferences and information demand of decision-makers facing uncertainty. We focus on monotone decision problems in which the posterior beliefs induced by the decision-maker’s information can be ordered so that higher actions are chosen in response to higher signal realizations. We provide necessary and sufficient conditions for decision makers with different classes of payoff functions to prefer one information structure to another. We also provide conditions under which two decision-makers in a given class can be ranked in terms of their information demand. Applications and examples are given.     

Asymmetry in government bond returns

Is there asymmetry in the distribution of government bond returns in developed countries? Can asymmetries be predicted using financial and macroeconomic variables? To answer the first question, we provide evidence for asymmetry in government bond returns in particular for short maturities. This finding has important implications for modeling and forecasting government bond returns. For example, widely used models for yield curve analysis such as the affine term structure model assume symmetrically distributed innovations. To answer the second question, we find that liquidity in government bond markets predicts the coefficient of skewness with a positive sign, meaning that the probability of a large and negative excess return is more likely in a less liquid market. In addition, a positive realized return is associated with a negative coefficient of skewness, or a small probability of a large and negative return in the future.     

The Increasing Selectivity of Foreign Aid, 1984–2003

The Monterrey Consensus includes the idea that foreign aid is more effective when targeted to countries with sound institutions. We examine the extent to which foreign aid, bilateral and multilateral, is “selective” in terms of democracy and property rights/rule of law. We find that multilateral assistance is more selective than bilateral aid in targeting countries with good rule of law. “Selectivity” is a new phenomenon. During 1984–89, both bilateral and multilateral aid had significant negative relationships with rule of law; by 2000–03 this had shifted to a significant positive relationship for multilateral aid, and a positive but statistically insignificant relationship for bilateral aid.     

GENDER, TECHNOLOGY AND ENVIRONMENT IN AGRICULTURE

The authors analyze the impacts of Southern Latin America integration on Brazilian agriculture. The first part describes the creation of MERCOSUL and its consequences on Brazilian agriculture. Two types of effects are investigated: how MERCOSUL may have induced improvements in the level of competitiveness of the local production of wheat; and the strategies for productive reintegration developed by wheat producers and other economic agents. Some conclusions are presented discussing agricultural diversification as an alternative to economic integration in southern Latin America.     

Regional Taxation and Retailing: The Economic Geography of the Internet

It is well established in the economics literature that before-tax prices are not independent of sales-tax rates. This paper shows that a sales-tax imposed in a high tax region can decrease the tax-included price for a buyer in a low tax region who purchases from a seller in the high tax region. Therefore, it may be more profitable for Internet retailers to be located in high tax regions. An empirical analysis shows that automobile manufacturers in the European Union (EU) set higher before-tax recommended prices for countries with low indirect taxes. This may contribute to the explanation of the flow of Internet automobile sales from high tax countries to low tax countries in the EU.
