Resumo O objetivo deste estudo foi avaliar a saliência, a relevância e a determinância da carne bovina para os consumidores de Dracena (SP), por meio de dois métodos de mensuração. A saliência foi determinada pelo método de elicitação livre (EL), a relevância e a determinância foram calculadas pelo modelo multinomial logit, com dados de um experimento de escolha discreta de melhor-pior (EEDMP) do caso 2. Para comparar as determinâncias, as preferências também foram estimadas empregando-se o modelo Probit, mediante declarações de intenções de compra de carne bovina. No momento da compra, o atributo mais saliente é a cor da carne, ao passo que o sabor e a textura são os atributos mais salientes durante o consumo. Resultados mostram ainda discrepâncias entre a determinância obtida pelo EEDMP e pelas intenções de compra. As preferências expressadas pelas intenções de compra se aproximam mais da literatura especializada, o que indica que a carne saborosa, macia e vermelha brilhante é a mais apreciada entre os consumidores. Ainda é prematuro fazer recomendações do uso concatenado da EL e do EEDMP para estimar as três dimensões das características de um produto, como a carne bovina.

Voter Choice

A key concept of social choice is the idea of the Condorcet point or core. For example, consider a voting game with four participants so any three will win. If voters have Euclidean preferences, then the point at the center will be unbeaten. Earlier spatial models of social choice focused on deterministic voter choice. However, it is clear that voter choice is intrinsically stochastic. This chapter employs a stochastic model based on multinomial logit to examine whether parties in electoral competition tend to converge toward the electoral center or respond to activist pressure to adopt more polarized policies. The chapter discusses experimental results of the idea of the core explores empirical analyses of elections in Israel and the United States.

Translating party pledges into coalition agreements is a crucial goal of after-election coalition negotiations. Full adoption is the best result for the bargaining party, while limited adoption is a kind of compromise forced by coalition partners, and non-adoption can be seen as a defeat. The question of what undermines the compromise and defeat in coalition agreements is, however, rarely answered. This article formulates hypotheses concerning the effect of consensual pledges among coalition parties, and party and voter-issue salience on parties’ ability to adopt their pledges and adopt them fully or partially. The effect of party level characteristics is considered. The analysis is provided on a new dataset of narrow Czech coalition party pledges in three governments established after elections in 2006, 2010 and 2013. Multinomial logit regression is used for the statistical analysis.

Joint Pricing

In this article, we investigate a joint pricing and inventory problem for a retailer selling fresh agriproducts (FAPs) with two-period shelf lifetime in a dynamic stochastic setting, where new and old FAPs are on sale simultaneously. At the beginning of each period the retailer makes ordering decision for new FAP and sets regular and discount price for new and old inventories, respectively. After demand realization, the expired leftover is disposed and unexpired inventory is carried to the next period, continuing selling. Unmet demand of all FAPs is backordered. The objective is to maximize the total expected discount profit over the whole planning horizon. We present a price-dependent, stochastic dynamic programming model taking into account zero lead time, linear ordering costs, inventory holding, and backlogging costs, as well as disposal cost. Considering the influence of the perishability, we integrate a Multinomial Logit (MNL) choice model to describe the consumer behavior on purchasing fresh or nonfresh product. By way of the inverse of the price vector, the original formulation can be transferred to be jointly concave and tractable. Finally we characterize the optimal policy and develop effective methods to solve the problem and conduct a simple numerical illustration.
