Shortfall aversion

Shortfall aversion reflects the higher utility loss of spending cuts from a reference than the utility gain from similar spending increases. Inspired by Prospect Theory's loss aversion and the peak‐end rule, this paper posits a model of utility from spending scaled by past peak spending. In contrast to traditional models, which call for spending rates proportional to wealth, the optimal policy in this model implies a constant spending rate equal to the historical peak when wealth is relatively large. The spending rate increases when wealth reaches a model‐determined multiple of peak spending. In 1926–2015, shortfall‐averse spending is smooth and typically increasing.     

Taxes and capital structure: evidence from firms' response to the Tax Reform Act of 1986

While the theoretical relation between taxes and capital structurehas been extensively analyzed, the empirical evidence on thisissue has thus far been inconclusive. One of the main difficultiesconfronting previous empirical studies of the cross-sectionalrelationship between taxes and leverage was the control of interveningvariables. The Tax Reform Act of 1986 (TRA), which drasticallychanged the tax regime, provides a unique opportunity to assessthe interaction between taxes and leverage decisions in a controlledenvironment. We test the relationship between leverage and certaintax-related variables for a large sample of companies in theyears surrounding the enactment of the TRA. The results supportthe tax-based theories of capital structure. The findings indicatethat there exists a substitution effect between debt and nondebttax shields, and that both corporate and personal tax ratesaffect leverage decisions.     

If Time Is Money Is It a Common Currency? Time in Anglo,Asian, and Latin Cultures

ABSTRACT

Social time affects the timing and frequency of purchases, the hours consumers patronize businesses, and how long consumers expect products to last. Understanding how culturally based social time attitudes differ will help marketers tailor their offerings and messages to consumers whose concepts of time differ. This exploratory study combined related streams of time literature to examine constructs of social time differences across cultures. Drawing upon a sample of 1377 respondents from six countries representing three cultural groups (Anglo, Latin, and Asian), the study explores the similarity and differences of cultural social time differences among these three groups.     

The default heuristic in strategic decision making: When is it optimal to choose the default without investing in information search?

Many studies have shown that decision makers have a tendency to choose the default or standard action among several possible actions. The article develops a model to explore under what conditions it is optimal for a firm facing a strategic decision problem to choose the default action without investing in obtaining more information that allows a more accurate decision. The model shows that the strategy to follow the default without additional information (“the default heuristic”) is more likely to be optimal when the cost of obtaining information is higher, and when the variation in possible outcomes is lower. The model also analyzes the optimal level of information search, showing that if the firm chooses to obtain information at all, it will invest in more accurate information when the cost of obtaining information is lower and when the variation in possible outcomes is lower.     

Contagious Speculation and a Cure for Cancer: A Nonevent that Made Stock Prices Soar

A Sunday New York Times article on a potential development of new cancer-curing drugs caused EntreMed's stock price to rise from 12.063 at the Friday close, to open at 85 and close near 52 on Monday. It closed above 30 in the three following weeks. The enthusiasm spilled over to other biotechnology stocks. The potential breakthrough in cancer research already had been reported, however, in the journal Nature , and in various popular newspapers (including the Times ) more than five months earlier. Thus, enthusiastic public attention induced a permanent rise in share prices, even though no genuinely new information had been presented.     

RETURNS TO SCALE IN RETAIL TRADE*

This paper attempts to estimate genuine scale effects in retail trade from a cross section of retail stores in Israel. This is done by estimating a simple production function for several retail branches and employing the faithful old direct Cobb-Douglas structure with value added as output and labor and capital inputs. And indeed despite the well-known peculiarities of the retail industry, a cross section estimation produces “normal” production-function estimates with reasonable input elasticities. The estimates also identify marked increasing returns-to-scale parameters, higher in food and lower in branches less affected by consumer participation and geographical dispersion. These increasing returns may explain a good part of the increase in sales per unit of inputs observed in time series.     

Capital asset pricing in an overlapping generations model

This paper attempts to contribute to two rapidly growing branches in economic theory: asset pricing and “overlapping generations” models. The model is formulated and it is shown that equilibrium prices exist, and some of their properties are discussed. Then the model is applied to an asymmetric information environment to see if randomness in the number of informed agents could confuse the uninformed. Surprisingly, it could not.
