DISCRETE CHOICE AND RATIONAL INATTENTION: A GENERAL EQUIVALENCE RESULT

This article establishes a general equivalence between discrete choice and rational inattention models. Matějka and McKay (2015) showed that when information costs are modeled using the Shannon entropy, the choice probabilities in the rational inattention (RI) model take the multinomial logit form. We show that, for one given prior over states, RI choice probabilities may take the form of any additive random utility discrete choice model (ARUM) when the information cost is a Bregman information, a class defined in this article. The prior information of the rationally inattentive agent is summarized in a constant vector of utilities in the corresponding ARUM.     

Conflict heterogeneity in Africa

The economic development literature widely concurs that conflicts have adverse economic consequences that contribute to poverty, disinvestment and lower human capital leading to widespread inequality and lower economic growth. As such, understanding the nature of conflict has been an important focus for political leaders, policymakers and researchers alike. However, the existing literature does not typically distinguish between the effects of conflict determinants on conflicts by type of actor or aggressor (i.e. state, group and civilian-based). Using panel data analysis for 46 African countries from 1997 to 2017, and a comprehensive geo-referenced Armed Conflict Location and Event Data (ACLED) conflict dataset, we find evidence of variation in the determinants' effects on conflicts by actor types. For the full sample of countries, we find that military expenditure decreases civilian-based conflicts; globalisation increases both state- and civilian-based conflicts while state fragility increases group-based conflicts. On the other hand, income per capita increases all three types of conflicts. At regional level, we find variation in the effects of military expenditure and globalisation on state- and civilian-based conflicts. However, we find little variation in the effects of the determinants on group-based conflicts across the regions. The findings highlight the nuances in conflicts by actor types and their causes which need to be accounted for when formulating conflict resolution policies.     

The Moral Disillusionment Model of Organizational Transgressions: Ethical Transgressions Trigger More Negative Reactions from Consumers When Committed by Nonprofits

Journal of Business Ethics - We tested whether the impact of an organizational transgression on consumer sentiment differs depending on whether the organization is a nonprofit. Competing hypotheses...     

Navigating compromise: How founder authenticity affects venture identification amidst organizational hybridity

Founders of hybrid ventures encounter organizational tensions that can compel compromise in both their organizations' and their own personal values. Such compromises may, in turn, undermine founders' identification with their ventures. In a multi-case study analysis we examine why social entrepreneurs differ in their responses to organizational tensions, both at the firm- and individual-level, and how such differences relate to their venture identification. Specifically, our findings reveal that strategic decisions made in the context of values-based complexity are often accompanied by concerns regarding founder authenticity—that is, judgments about the alignment between founders' actions and the commitments or responsibilities associated with their identities as entrepreneurs. Yet, because founders differ in the basis from which they seek to maintain such alignment, these differences shape both hybridity management and subsequent venture identification. By unpacking such differences, our findings contribute new theory, bridging recent scholarship on founder authenticity with longstanding research on organizational identification and hybrid organizing.     

On the quest for supply chain transparency through Blockchain: Lessons learned from two serialized data projects

The ability to look into the supply chain has long enticed SCM scholars and practitioners. The possibilities created by such visibility are endless—from risk reduction and continuity planning to inventory management and cost reduction, nothing is off the table when end‐to‐end visibility is a possibility. Because of such enticements, there is usually much buzz in the industry every time a new technology that promises visibility and transparency is brought forward. Yet, years later, stories sometimes emerge that said technologies either failed to deliver or were not everything they were made out to be. Blockchain is yet another emerging technology in this space. Some consultants promise that it will be the final answer to the transparency and visibility woes that companies currently face. Yet, there is little empirical investigation regarding how the technology may benefit adopters, what the bottlenecks may be, and to what extent it may be able to deliver on these promises, without massive system‐wide upgrades of extant hardware and computing prowess. The current study takes a step in this direction by investigating a blockchain‐driven proof of concept across an industry consortium to identify promises, possibilities, and challenges of blockchain.     

THE EFFECT OF MARIJUANA DISPENSARY OPENINGS ON HOUSING PRICES

We evaluate the effect of medical and recreational dispensary openings on housing prices in Denver, Colorado. Using an event study approach, we find that the introduction of a new dispensary within a half‐mile radius of a new home increases home prices by approximately 7.7% on average. The effect diminishes for homes further from new dispensaries but is consistent over time. Our results provide important and timely empirical evidence on the socioeconomic impacts of marijuana legalization. (JEL R32, R38, R5)     

TESTING THE QUANTAL RESPONSE HYPOTHESIS

We develop a nonparametric test for consistency of player behavior with the quantal response equilibrium (QRE). The test exploits a characterization of the equilibrium choice probabilities in any structural QRE as the gradient of a convex function; thereby, QRE‐consistent choices satisfy the cyclic monotonicity inequalities. Our testing procedure utilizes recent econometric results for moment inequality models. We assess our test using lab experimental data from a series of generalized matching pennies games. We reject the QRE hypothesis in the pooled data but cannot reject individual‐level quantal response behavior for over half of the subjects.     

USING A LAPLACE APPROXIMATION TO ESTIMATE THE RANDOM COEFFICIENTS LOGIT MODEL BY NONLINEAR LEAST SQUARES*

Current methods of estimating the random coefficients logit model employ simulations of the distribution of the taste parameters through pseudo‐random sequences. These methods suffer from difficulties in estimating correlations between parameters and computational limitations such as the curse of dimensionality. This article provides a solution to these problems by approximating the integral expression of the expected choice probability using a multivariate extension of the Laplace approximation. Simulation results reveal that our method performs very well, in terms of both accuracy and computational time.     

Trends,random walks,and tests of the permanent income hypothesis

Recent studies find that consumption is excessively sensitive to income. These studies assume that income is stationary around a deterministic trend. The data, however, do not reject the hypothesis that disposable personal income is a random walk with drift. If income is indeed a random walk, then the standard testing procedure is greatly biased toward finding excess sensitivity. Moreover, if income follows either a more general non-stationary process or a borderline stationary process, this procedure is also seriously biased.
