Could immigration explain wage inequality in a skill-biased technological model?

The aim of this paper is to evaluate how immigration of high-skilled workers affects the technological-knowledge bias and, in turn, the skill premium in the host countries, in particular bearing in mind the recent experience in a number of European countries. We study a skill-biased dynamic general equilibrium R&D growth model in which the standard R&D technology is modified so wage inequality results from the direction of the technological knowledge, which in turn is induced by the price channel. By solving the transitional dynamics numerically, we show that the rise of the skill premium arises from the price-channel effect, complemented with a mechanism that reflects the impact of immigration on R&D. According to our quantitative results, our model is able to account for a significant proportion of the dynamics of the skill premium in the data for a number of European countries, thus, suggesting that differences in labour skills between immigrants and natives are, in practice, an important source of skill premium variation over time.     

The impact of health sector on R&D,economic growth and wages

We extend the existing R&D growth literature by focusing on the short-, medium-, long-run effects of the health sector on R&D intensity, economic growth and wages, and by considering 21 OECD countries between 1991 and 2008. We show that: (i) there is a unique and stable steady state; (ii) an increase in health-labour share in skilled population has no effect on growth, but affects negatively (positively) the R&D intensity (the skill premium); (iii) Anglo–Saxons countries have the lowest health-labour share in skilled-labour population, and Nordic countries have the lowest skill premium and the highest consumption/production of healthcare per capita.     

Direct finance in the Dutch Golden Age†

This article analyses private credit operations in Amsterdam in the seventeenth century to explain the absence of deposit banks. The financial system was highly segmented and a combination of declining business margins and narrow interest rate spreads cut the scope for deposit taking. Moreover, merchants had easy access to credit in the form of short‐term loans which could be easily rolled over, or replaced at will. This technique worked well because a market developed providing key functions to control risk and price loans accordingly.     

A new consensus-based unemployment indicator

In this study we present a novel approach to measure the level of consensus among agents’ expectations. The proposed framework allows us to design a positional indicator that gives the percentage of agreement between survey expectations. While other aggregation methods such as the balance, which is constructed as the difference between the percentages of respondents giving positive and negative replies, explicitly omit the neutral information, the proposed metric allows synthesizing the information coming from all response categories, including the percentage of respondents who do not expect any change. In order to assess the performance of the proposed measure of consensus, we compare its ability to track the evolution of unemployment to that of the balance in eight European countries. With this aim, we scale both measures to generate one-period ahead forecasts of the unemployment rate. We find that the consensus-based unemployment indicator outperforms the balance in all countries except Denmark and Sweden, which suggests that the level of agreement among agents’ expectations is a good predictor of unemployment.     

Feasible implementation of taxation methods

This paper studies implementation of taxation methods in one-commodity environments in which the incomes of the agents are unknown to the planner. Feasibility out of equilibrium imposes that the mechanism depend on the environment. We present two mechanisms. The first one, which requires complete information, implements every taxation method in Nash, strong and coalition-proof equilibrium. The second, where informational requirements are relaxed, implements a large class of consistent and monotone methods in subgame perfect equilibrium. Neither mechanism employs the off-equilibrium devices used by the general theory. Under fully private information no method is implementable. Received: 12 March 1997 / Accepted: 21 July 1998     

Tax competition for foreign direct investments and the nature of the incumbent firm

We investigate tax/subsidy competition for foreign direct investments (FDI) between countries of different size when a domestic firm is the incumbent in the largest market and we study how the nature (public or private) of the incumbent firm affects policy competition. We show that, differently from the case of a private firm, the country hosting the incumbent always benefits from FDI if the domestic firm is a public welfare‐maximizing firm. We also show that the public firm acts as a disciplinary device for the foreign multinational that will always choose the efficient welfare‐maximizing location. An efficiency‐enhancing role of policy competition may then arise only when the domestic incumbent is a private firm, whereas tax competition is always wasteful in the presence of a public firm.     

Assessment of the effect of the financial crisis on agents’ expectations through symbolic regression

Agents’ perceptions on the state of the economy can be affected during economic crises. Tendency surveys are the main source of agents’ expectations. The main objective of this study is to assess the impact of the 2008 financial crisis on agents’ expectations. With this aim, we evaluate the capacity of survey-based expectations to anticipate economic growth in the United States, Japan, Germany and the United Kingdom. We propose a symbolic regression (SR) via genetic programming approach to derive mathematical functional forms that link survey-based expectations to GDP growth. By combining the main SR-generated indicators, we generate estimates of the evolution of GDP. Finally, we analyse the effect of the crisis on the formation of expectations, and we find an improvement in the capacity of agents’ expectations to anticipate economic growth after the crisis in all countries except Germany.     

US deficit sustainability revisited: a multiple structural change approach

In this article we re-examine the long-run sustainability of US budget deficits, using Bai and Perron's multiple structural change approach. While the deficit would have been weakly sustainable over the full sample (1947:1–2005:3), strong sustainability would appear only between January 1982 and February 1996.     

The effects of store brand loyalty on store loyalty: evidence from the Spanish market

This article studies the impact of retailers' store brands on store performance. Specifically, we analyze the extent to which store brands contribute to store loyalty. On the one hand, a positive relationship between customers' familiarity with and loyalty to the retailer's own brand and customers' loyalty to the retailer should result from the potential of the store brand to differentiate the retailer. On the other hand, an negative relationship between customers' familiarity with and loyalty to the retailer's own brand and customers' loyalty to the retailer may result from store brands' association with more price-sensitive customers, who have a higher propensity to buy at different stores that offer the best bargain. The empirical analysis, conducted with a sample of customers of leading retailers in the Spanish detergent market, shows no relationship between store brand loyalty and loyalty to the retailer. Although the purchase of store brands relates positively to higher loyalty to the retailer, this relationship deteriorates with the degree of exclusivity of store brands within the customer's shopping basket.     

Can the North–South trade regime explain intra- and inter-country productivity differences?

The literature identifies North–South disparities in Total Factor Productivity (TFP), which, in turn, justify the bulk of international income differences. By building a dynamic, general equilibrium model of North–South technological-knowledge diffusion with scale-invariant growth, we extend the literature in several directions: (i) growth is driven by Schumpeterian R&D and by high and low-skilled human-capital accumulation; (ii) three trade regimes are considered; (iii) sectoral and aggregate TFP measures are computed; (iv) the extent to which the North–South trade regime explains intra-country TFP and inter-country TFP differences is evaluated. In particular, the results suggest that intra-country TFP differences increase and inter-country TFP differences fall when countries are more interdependent.
