This paper studies the competition between Web 2.0 communities in a game theoretic framework. We model three important features of these institutions: (i) firms' content is usually user-generated; (ii) consumers' content preferences are governed by local network effects, and (iii) consumers have strong tendencies to multi-home. Our analyses reveal that ex-ante identical community sites can acquire differentiated market positions that spontaneously emerge from user-generated content.

During the 2014 EPIC Conference, Allen Batteau and Robert J. Morais led a workshop entitled “Toward Conceptual, Methodological, and Ethical Standards of Practice in Business Anthropology.” This article summarizes the objectives and results of the workshop.

The paper investigates the long-run consequences of multichannel shopping on customers' spending. Using data from a major US catalog company which introduced an online channel, our results validate previous findings that multichannel customers spend more than mono-channel customers in the short run. However, the difference in spending dissipates over time with multichannel customers reverting to their regular consumption pattern in 3 years.

Shortfall aversion reflects the higher utility loss of a spending cut from a reference point than the utility gain from a similar spending increase, in the spirit of Prospect Theory's loss aversion. This paper posits a model of utility of spending scaled by a function of past peak spending, called target spending. The discontinuity of the marginal utility at the target spending corresponds to shortfall aversion.

This essay analyzes some problems that accounting standard setters confront in erecting barriers to managers bent on boosting their firms' financial reports through financial engineering (FE) activities. It also poses some unsolved research questions regarding interactions between preparers and standard setters. It starts by discussing the history of lease accounting to illustrate the institutional disadvantage of standard setters relative to preparers in their speeds of response.

We comment on Gilovich and colleagues' program of research on happiness resulting from experiential versus material purchases, and critique these authors' interpretation that people derive more happiness from experiences than from material possessions. Unlike goods, experiences cannot be purchased, and possessions versus experiences do not seem to form the endpoints of the same continuum.

Six years after the passage of the 2008 Troubled Asset Relief Program, commonly known as TARP, it remains hard to measure the total social costs and benefits of the assistance to banks provided under TARP programs. TARP was not a single approach to assisting weak banks but rather a variety of changing solutions to a set of evolving problems. TARP's passage was associated with significant improvements in financial markets and the health of financial intermediaries, as well as an increase in the supply of lending by recipients.

We analyze strategic speculators' incentives to trade on information in a model where firm value is endogenous to trading, due to feedback from the financial market to corporate decisions. Trading on private information reveals this information to managers and improves their real decisions, enhancing fundamental value. While this feedback effect increases the profitability of buying on good news, it reduces the profitability of selling on bad news, and thus has an asymmetric effect on trading behavior.

We consider a non-stationary variant of a sequential stochastic optimization problem, where the underlying cost functions may change along the horizon. We propose a measure, termed variation budget, that controls the extent of said change, and study how restrictions on this budget impact achievable performance. We identify sharp conditions under which it is possible to achieve long- run-average optimality and more refined performance measures such as rate optimality that fully characterize the complexity of such problems.
