Liquidity protection versus moral hazard: the role of the IMF

A game between the IMF, a country and atomistic private investors is motivated by recent crises including that in Argentina. The one stage game has no Nash equilibrium in pure strategies. Considering an equilibrium in mixed strategies, conditions are derived on whether the IMF should exist. A “cooperative first best” may be supported in a repeated game by a “minimum punishment strategy” but breaks down as the probability of insolvency rises. Countries are likely to deviate in bad times placing the IMF in an “impossible position”. The international financial architecture (IFA) remains incomplete.     

The Tragic Consumer: A Nietzschean Reading of Irremediably Unsatisfactory Consumption

This essay criticizes the romantic ethic of consumption (Campbell, 1987) from the tragic perspective (Nietzsche, 2006). By tragic, we refer to the constant tension between Apollo and Dionysius (Nietzsche, 2006, p. 47). It is suggested that the romantic ethic of consumption, which orders our existence, is associated with Apollonian ideals, thus, creating a protective and individuating illusion against the chaotic, the amorphous, and the contradictory—characteristics associated with the Dionysian. What has been considered as the romantic-Apollonian ethic of consumption promises to satiate our desires (Campbell, 2006), even though this is not possible since incompleteness is inherent to the individual (Freud, 1996, 1997). This ethic may prove frustrating for some consumers since the satiation of wills has a transient effect and the individual therefore remains in a state of desire. In cases like these, an alternative to the romantic meaning would be the adoption of a tragic conception of consumption, a conception consubstantiated in the knowledge of its uselessness as a strategy to recover a lost completeness. Thus, this article describes the figure of the tragic consumer, the one who knows the chaotic side of the act of consuming, but who reaffirms his or her will, either consuming—since he perceives that there is no escape from the logic imposed by consumption—or by choosing to abandon specific categories of goods that do not respond to the reiteration of his will. As a practical instance for the development of this critique, we have reflected on the phenomenon of category abandonment (Suarez & Chauvel, 2012).     

Separation of powers and the tax level in the U.S. states

We estimate a nonlinear and discontinuous relationship between the tax level and the degree of alignment between the legislature and the governor, measured as the number of seats in the legislature that belong to the governor's party. In the states with the line‐item veto, the tax level jumps at the point where the government switches from divided to unified. With a regression discontinuity design, we show that this jump can be interpreted as a causal effect. We propose a simple model to account for this nonlinear relationship. The sequential nature of the budget bargaining game, that is, the legislature proposes and the governor cuts with the line‐item veto, implies that the tax level is determined by the overlap between the supporters of the governor and the supporters of the legislative majority. Changes in the size of the overlap determine the tax level.     

Influences of visual attributes of food packaging on consumer preference and associations with taste and healthiness

Two experiments designed to investigate how the shape and colour of packaging, and product category, conjointly impact consumers’ product and packaging expectations are reported. In Experiment 1, the shape (rounded vs. angular) and visual appearance (greyscale, red‐to‐yellow and blue‐to‐green colour schemes) of the packaging were manipulated. Dependent measures were preference (willingness to purchase the product, how attention‐capturing the packaging is, and the pleasantness of the design) and any taste associations. In Experiment 2, shape (rounded vs. angular), colour (red‐to‐yellow vs. blue‐to‐green colour schemes), and product category (buttery vs. cereal cookies) were manipulated. In this case, the dependent measures were the perceived product healthiness and the preference of consumers. The results of Experiment 1 revealed that packaging colour influenced product preference. Red‐to‐yellow and blue‐to‐green colour schemes and angular packaging were preferred over greyscale and round packaging. Colour also influenced taste associations, while shape only influenced ratings of expected sweetness. In Experiment 2, packaging shape and product category influenced product preference. In particular, rounded packaging and the packaging of buttery cookies were preferred over angular packaging and the cereal cookies packaging. The healthiness of the product was rated higher for the rounded and red‐to‐yellow packaging containing a buttery product. Taken together, these results highlight the important role played by colour, shape, and category on the expectations and associations elicited by viewing product packaging.     

Two applications of wild bootstrap methods to improve inference in cluster‐IV models

Microeconomic data often have within‐cluster dependence, which affects standard error estimation and inference. When the number of clusters is small, asymptotic tests can be severely oversized. In the instrumental variables (IV) model, the potential presence of weak instruments further complicates hypothesis testing. We use wild bootstrap methods to improve inference in two empirical applications with these characteristics. Building from estimating equations and residual bootstraps, we identify variants robust to the presence of weak instruments and a small number of clusters. They reduce absolute size bias significantly and demonstrate that the wild bootstrap should join the standard toolkit in IV and cluster‐dependent models.     

Second-order ambiguous beliefs

This paper axiomatizes models of second-order ambiguous beliefs in the original domain of preferences of Anscombe and Aumann (Ann Math Stat 34:199–205, 1963) by weakening the first-stage independence postulate. The models we propose include the second-order subjective expected utility (SOSEU) of Seo (Econometrica 77:1575–1605, 2009) as a particular case. We characterize the intersection of our models of second-order ambiguity with the canonical models of (first-order) ambiguity aversion and provide a further generalization of SOSEU by relaxing the completeness axiom.     

Relevance of trade facilitation in emerging countries' exports

The objective of this article is to analyse trade flows in emerging nations with a maritime boundary, where trade facilitation plays a decisive role in their international development. In order to detect possible patterns in performance, we apply the economic approach of gravity models using the World Bank Logistic Performance Index (LPI) as a good proxy of trade facilitation. The results of the estimation lead to the conclusion that the more complex the transportation of goods is, the more influential the logistics indicator, trade facilitation being most prominent in Middle East exporters.     

Logistics performance and export competitiveness: European experience

Logistics performance has become a decisive factor in export competitiveness. At the same time, and as a result of the continuous enlargement processes it has undergone, the European Union (EU) is a very interesting case to study how the reforms that enhance logistics performance have affected exports. Therefore, this paper aims to analyse the importance of logistics performance in regard to EU exports over the period 2005–2010 in an attempt to identify possible advances on behalf of Member States. Several gravity equations are estimated using the Logistics Performance Index (LPI) and its components as characteristic proxy variables of trade facilitation. In order to avoid the possible heterogeneity caused by sample bias, the two-stage model proposed by Heckman is used. The estimations of the gravity models using the two-stage Heckman model for all 26 EU countries have led us to conclude that logistics was more important for exporting nations than importing nations in both 2005 and 2010, reinforcing the interest in the exporter side of the paper. In reference to the components of the LPI, Competence and Tracking has acquired greater importance in recent years, in keeping with the weak domestic demand in European countries and the search for new international markets.     

Mixture models of choice under risk

This paper is concerned with estimating preference functionals for choice under risk from the choice behaviour of individuals. We note that there is heterogeneity in behaviour between individuals and within individuals. By ‘heterogeneity between individuals’ we mean that people are different, in terms of both their preference functionals and their parameters for these functionals. By ‘heterogeneity within individuals’ we mean that the behaviour may be different even by the same individual for the same choice problem. We propose methods of taking into account all forms of heterogeneity, concentrating particularly on using a Mixture Model to capture the heterogeneity of preference functionals.
