International Pricing in a Generalized Model of Ideal Variety

We examine international markups and pricing in a generalized version of an "ideal variety" model. In this model, entry causes crowding in variety space, so that the marginal utility of new varieties falls as market size grows. Crowding is partially offset by income effects, as richer consumers will pay more for varieties closer matched to their ideal types. We show theoretically and confirm empirically that declining marginal utility of new varieties results in: a higher own-price elasticity of demand (and lower prices) in large countries and a lower own-price elasticity of demand (and higher prices) in rich countries. The model is also useful for generating facts from the literature regarding cross-country differences in the rate of variety expansion.     

DETERMINISTIC, STOCHASTIC, AND SEGMENTED TRENDS IN AGGREGATE OUTPUT: A CROSS-COUNTRY ANALYSIS

This paper examines whether output per capita in 126 countriesis better described as trend or difference stationary, usingappropriate finite-sample critical values. Depending upon whetherone uses solely a test with a trend stationary null, or solelyone with a difference stationary null, very different conclusionsare obtained. This outcome suggests that it is useful to considerthe tests complementary, rather than competing. We find thatwhen a definite characterization of GDP can be made, it is verylikely to indicate a difference stationary process. However,the likelihood of making definite conclusions does vary positivelywith both income level and data quality.     

The Mode of Acquisition in Takeovers: Taxes and Asymmetric Information

We develop a model in which the mode of acquisition conveys information concerning the value of the bidder. The model incorporates the possibility that offers containing both cash and stock can be made in a setting consistent with the U.S. tax code. We demonstrate that bidders with unfavorable private information about their equity value choose offers containing some stock to avoid the capital gains tax consequences of cash offers. The model yields a number of unique predictions about the construction of acquisition offers. We present evidence consistent with the model.     

The Work Program and Priorities of the AASB

The workload of the AASB has not diminished since adoption of the IASB's standards and will not diminish in the foreseeable future. However, the nature of the AASB's work has changed, with a particular focus on the public-sector and private not-for-profit sector priorities.     

Reinforcement Learning and Savings Behavior

We show that individual investors over‐extrapolate from their personal experience when making savings decisions. Investors who experience particularly rewarding outcomes from 401(k) saving—a high average and/or low variance return—increase their 401(k) savings rate more than investors who have less rewarding experiences. This finding is not driven by aggregate time‐series shocks, income effects, rational learning about investing skill, investor fixed effects, or time‐varying investor‐level heterogeneity that is correlated with portfolio allocations to stock, bond, and cash asset classes. We discuss implications for the equity premium puzzle and interventions aimed at improving household financial outcomes.
