Abstraction and product categories as explanatory variables for food consumption

This study sets out to explore variation in the consumer choice structure in relation to three types of products with different levels of search, experience and credence attributes. The decision structures of rice, wine and functional food (experience, search and credence products) consumers were explored by means of laddering. The results suggest the presence of an emotional component in foods that increases in complexity (becomes more abstract) with the number of credence attributes. The findings recommend adjusting the complexity of advertising campaigns and product positioning to the type of product being promoted.     

From real estate to consumption: the role of credit markets in the USA

The aim of this article is to test whether the credit market conditions affect the strength of transmission of real estate wealth effects on household consumption in the US economy. Although many different works have dealt with the analysis of the existence of a real estate wealth effect, most of them as a reaction to the dramatic increase of housing prices in several OECD countries, there are only few papers analysing whether the consumption response depends on the positive or negative sign of the wealth shock and, as far as we know, none of them takes the effects of credit market conditions on that asymmetric response into account. This article tries to fill the existing gap in the literature on this matter. From an econometric perspective, we estimate the asymmetries in the consumption response within the momentum threshold autoregressive model (M-TAR) proposed by Enders and Siklos (2001), but following Stevans (2004), it is applied to a multivariate framework. The main results show that the credit market conditions play a significant role in the transmission of changes in real estate wealth to consumption. In addition, we find that there exists an asymmetric behaviour in the US aggregate consumption spending responses to real estate wealth and credit market shocks, which is only significant when a negative shock takes place.     

A new approach to the identification of regional clusters: hierarchical clustering on principal components

This study focuses on the identification of regional business clusters as a primary step in the design and implementation of cluster-based development strategies. A methodology that has not been used previously to identify clusters is applied to data on inter-industry linkages from the input–output table of a region in northern Spain. The first advantage of this approach, hierarchical clustering on principal components (HCPC), over the use of factorial analysis alone, is that it involves the application of objective clustering techniques to the principal components analysis results, which leads to a better cluster solution. A second advantage is derived from using a mixed algorithm for the clustering process – a combination of the Ward’s classification method with the K-means algorithm – which improves the robustness of the final results.     

Disparities in the financial performance of agricultural entities according to the legal form: the case of Slovakia

Financial management in agricultural enterprises is affected by a range of factors that are not present in other sectors. One of the factors that affect the performance of enterprises is the legal or organizational form of the business. In Slovakia, the specific structure of farms is different from that of almost any other member state of the European Union. The aim of this paper is to evaluate the disparities in the financial performance of agricultural enterprises according to the legal form. We analysed and compared two groups of agricultural entities, agricultural cooperatives and business companies, for the period from 2005 to 2014. Based on an analysis of the differences using mathematical and statistical methods, we can conclude that the legal forms are distinguished in all monitored parameters and our hypothesis on the differences in economic performance of agricultural entities according to legal form was confirmed.     

Biotechnology as a Technological Paradigm in the Global Knowledge Structure

The aim of this study is to analyse whether the receipt of public R&D funding determines firm's R&D strategy selection. This issue is crucial, as previous studies have shown that each R&D strategy is associated to a higher, or lower, innovation performance. We consider three R&D strategies – make, buy, make–buy – and three different sources of public funding – regional, state and other (such as EU). The model estimation is performed through a multinomial logit model with random effects with a sample of 457 large firms for the period 1992–2005, taken from the Spanish Survey of Business Strategies. The main finding is that the source of the funding influences whether firms select the make, buy or make–buy strategy. Additionally, because of the panel structure of the sample, we observe that the effect of public funding on the R&D strategy selection lasts longer for state and regional funds than for other funds.     

Market Structure And The Adoption Of Innovations: The Case Of The Spanish Banking Sector ‡

This paper is an empirical study of the determinants of adoption time for the teleprocess terminal by Spanish commercial and savings banks. The explanatory variables include the characteristics of the adopting firms, size, and in the case of the savings banks, the structure of the market and concentration. The results indicate that the speed of adoption is maximized at intermediate levels of size and market concentration, confirming one theoretical prediction of models of diffusion: namely, that adoption time is minimized at intermediate levels of market concentration.     

Ugo Broggi: a precursor in mathematical economics

The concern for the existence of solution to the Walras - Cassel model is usually dated at the beginning of the 1930s, and one decade later the proof of existence of utility function. Ugo Broggi, however, posed both issues in 1923 and 1919, respectively, and even hinted at modern ways of solving them. He was an outstanding mathematician, a former disciple of David Hilbert and collaborator with the Giornale degli Economisti. Broggi's achievements are also linked to a critical reading of Osorio's treatise on Paretian economics.     

A Sraffian interpretation of classical monetary controversies

Abstract

The aim of this paper is to explore the contrasting views of inflation, exchange rate misalignments and determinants of gold flows held by different branches of the classical school during the first half of the nineteenth century. The properties of money neutrality and money endogeneity within the classical system are studied by reinterpreting these controversies through the analytical framework of the surplus approach as reconstructed by Sraffa [Production of Commodities by Means of Commodities. Cambridge: Cambridge University Press, 1960] and his followers.     

First-price auctions with resale: the case of many bidders

We study first-price auctions with resale when there are many bidders and derive existence and characterization results under the assumption that the winner of the initial auction runs a second-price auction with an optimal reserve price. The fact that symmetrization fails when there are more than two bidders has been observed before, but we also provide the direction: weaker bidders are less likely to win than stronger ones. For a special class of distributions and three bidders, we prove that the bid distributions are more symmetric with resale than without. Numerical simulations suggest that the more bidders there are, the more similar the allocation is to the case without resale, and thus, the more asymmetric the bid distributions are between strong and weak bidders. We also show in an example that the revenue advantage of first-price auctions over second-price auctions is positive, but decreasing in the number of bidders.
