A systemic approach to modelling and estimating demand for money(ies)

This article uses a consumer theory-based systemic approach to model the demand for monetary liquid asset holdings in Chile. We implement the suggestions and caveats of aggregation theory for the estimation of a demand system for liquid assets (monies) in static, dynamic and time-varying parameters setups. Our results are robust and theoretically consistent with consumer theory restrictions, as a system derived from a utility maximizing framework and a quasi concave utility function. In our estimations, we find stability of interest rate elasticities, in contrast to previous related literature. We also document evidence that long (short) maturity rates are associated to less (more) liquid assets.     

Measuring Market Conduct in the Brazilian Cement Industry: A Dynamic Econometric Investigation

Indirect assessments of market conduct have become widespread in the New Empirical Industrial Organization—NEIO literature. Recently, Steen and Salvanes (1999, Int J Ind Organ 17:147–177) provided a flexible dynamic econometric formulation of the approach advanced by Bresnahan (1982, Econ Lett 19:87–92) and Lau (1982, Econ Lett 10:93–99). The present paper considers a similar approach applied to regional cement markets in Brazil under more favorable data availability, and attempts to address part of the concerns that usually emerge with respect to the NEIO literature. In particular, issues pertaining to structural stability and the control for the number of competing firms are addressed. The evidence clearly indicates non-negligible and distinct market power in different regions and also distinct conduct patterns in the short and long run.      

Consumers’ Social Media Brand Behaviors: Uncovering Underlying Motivators and Deriving Meaningful Consumer Segments

The current research identifies the range of social media brand behaviors (i.e., brand touch points) that consumers can exhibit on social media, and subsequently queries a representative sample of consumers with regard to such behaviors. The analysis reveals four underlying motivators for consumers’ social media behaviors, including brand tacit engagement, brand exhibiting, brand patronizing, and brand deal seeking. These motivators are used to derive meaningful consumer segments identified as content seekers, observers, deal hunters, hard‐core fans, posers and, respectively, patronizers, and described through co‐variates including brand loyalty, brand attachment, and social media usage. The findings are critically discussed in the light of literature on the needs that consumers meet through brand consumption and on the types of relationships consumers build with brands. Not least, the managerial implications of the current findings are debated.     

GLOBAL GAMES WITH STRATEGIC SUBSTITUTES

We study global games with strategic substitutes. Specifically, for a class of binary‐action, ‐player games with strategic substitutes, we prove that under payoff asymmetry, as incomplete information vanishes, the global games approach selects a unique equilibrium. We characterize this equilibrium profile ; players employ switching strategies at different cutoff signals, the order of which is directly determined by payoff asymmetry. We provide examples that illustrate our result and its connection with dominance solvability. We extend the global game literature, which has thus far been developed for games with strategic complementarities, to new applications in industrial organization, collective action problems, finance, etc .     

Tourism and cultural revival

Cultural change is a recurrent concern in tourism anthropology studies. Host societies frequently remodel their culture following the creation of a tourist resort. But, that does not necessarily imply an acculturating process, since what actually takes place is pragmatic cultural production work in response to the touristic demands that offer consolidated economic alternatives and livelihood. As for the Pataxó Indians of Porto Seguro of Brazil, they have sponsored a “cultural revival” process. In other words, they have generated the traditions that start being exhibited commercially in arenas where the prospect of emergent ethnic tourism is perceived.     

Draining the judiciary bottleneck: A quasi-experiment in improving a government service

This study describes judicial reform as a quasi-experiment. The reform is the deployment and implementation of the GICA-Justicia (Gestión Integral de Calidad y Acreditación: Quality and Accreditation Integral Management) Quality-Management Standard (QMS) within the Second Court of Appeal of Costa Rica's Supreme Court; the reform includes process improvements following the implementation. The study of impact includes a direct comparison to its homologous in Panama's Justice System. The GICA-Justicia emerges in the QMS environment as a process-performance tracking and improvement tool for accreditation of district courts and courts of appeal. This study offers “sui generis state of the art” empirical know-how via the use of an interrupted time series quasi-experiment. This study contributes to literature by unveiling a successful new judicial service improvement design in a Latin-American context.     

MLP ensembles improve long term prediction accuracy over single networks

This work describes an award winning approach for solving the NN3 Forecasting Competition problem, focusing on the sound experimental validation of its main innovative feature. The NN3 forecasting task consisted of predicting 18 future values of 111 short monthly time series. The main feature of the approach was the use of the median for combining the forecasts of an ensemble of 15 MLPs to predict each time series. Experimental comparison to a single MLP shows that the ensemble increases the performance accuracy for multiple-step ahead forecasting. This system performed well on the withheld data, having finished as the second best solution of the competition with an SMAPE of 16.17%.     

Origin of FDI and Intra‐Industry Domestic Spillovers: The Case of Greek and European FDI in Bulgaria

This paper uses firm‐level data to assess the horizontal impact of foreign firm ownership on domestic productivity in Bulgaria. We identify a theoretical tradeoff between technological distance (of domestic versus foreign firms) and internalization capacity (of spillovers) and examine the extent to which this is reflected in the impact on the domestic economy of different types and origins of FDI. Emphasis is placed upon the effects of Greek FDI, which is known to be of a distinctively “regional” character. We find that Greek FDI produces significantly larger positive spillovers, which appear more suitable for the Bulgarian context of transition and economic restructuring. We also unveil some notable “hysteresis” and “technology bias” effects for FDI spillovers of all origins, as well as some country‐specific ownership‐structure and threshold effects.     

Regional relationships between inherent coffee quality and growing environment for denomination of origin labels in Nariño and Cauca,Colombia

International markets are increasingly signaling demand for quality-differentiated coffee, which the Colombian Coffee Growers Federation (FNC) proposed to exploit to identify those regional coffees that would fulfill the requirements to be classified as denomination of origin. The objective of this study was to develop and implement a sound, robust and repeatable approach with and for the FNC to identify regional causal relationships between coffee quality and environmental characteristics as bases for labels of denomination of origin. Environmental differences between coffee-growing areas in the departments of Cauca and Nariño were statistically significant for several characteristics, including the number of dry months, annual precipitation and diurnal temperature range. The dominant varieties (Caturra and Colombia) did not show major differences in quality attributes, and were pooled for the analyses with the environmental data. There are significant differences in biochemical and sensorial product characteristics between the two departments. The spatial patterns in product characteristics exhibit a non-random, regionally-changing structure that is related to those in the environmental data. The generated results provided ample evidence to support the application for regionally-based denominations of origin. Recommendations were derived to help mainstreaming the developed approach and thereby facilitate policy decisions for its use in other geographies and with other crops. Furthermore, the importance of systematic interdisciplinary institutional collaboration for large-scale denomination of origin projects was corroborated for food policy dialogue and decision making. It seems plausible that producers of high-quality products within other commodities are likely to follow the FNC in seeking denomination of origin for their goods. The presented approach is crucial to facilitate policy.
