Financial Constraints for Innovation in Brazil

This paper analyzes the presence of financial constraints for investment in innovation in Brazil. Dynamic investment models are estimated for a panel dataset of 206 Brazilian non-financial firms in the period 1995–2006. Results show that innovation of Brazilian firms is subject to financial constraints in line with previous international evidence. Innovation of Brazilian firms is adversely affected by leverage and also depends on internally generated funds. The models presented incorporate relevant firm characteristics for financial constraints. Our findings suggest the need for further advances at micro- and macroeconomic levels in Brazil to mitigate the observed financial constraints.     

The consumption-real exchange rate anomaly: nontraded goods and distribution services

An empirical analysis of risk sensitivity of supply response is attempted here for seven major field crops in California over a twenty-two year period 1949–70. Two distinct types of risk sensitivity are evidenced by the empirical trend e.g., for crops like alfalfa, sugarbeets and sorghum, where short run adjustment factors are important, the year-to-year acreage changes reflect the negative impact of price and returns risk very strongly. For other crops like rice and barley, where long run factors of adjustment are important, the impact of price changes rather than the variance of prices or returns are more important. This pattern of risk sensitivity has important economic implications for welfare gains resulting from price support and stabilization policies pursued by the federal government.     

The long-run decline in the share of agricultural and food products in international trade: a gravity equation approach to its causes

The objective of this study is to determine the causes of the loss of share of agricultural products and food in international trade. The article compares, using a gravity model, the impact of various factors upon bilateral trade in agricultural products, in manufactures and in total trade, between 1963 and 2000 for a representative sample of 40 countries. The results clearly demonstrate how the low demand elasticity for agricultural products and food, the high degree of protectionism to which they were subjected and their meagre share in intra-industrial trade are the principal causes of their relatively slow growth.     

Information Gathering and Marketing

Consumers have only partial knowledge before making a purchase decision, but can acquire more‐detailed information. Marketing makes it easier or harder for these consumers to do so. When consumers are ex ante heterogeneous, the firm might choose an intermediate marketing strategy for two quite different reasons. First, as a nonprice means of discrimination—it can make information only partially available, in a way that induces some, but not all, consumers to acquire the information. Second, when the firm cannot commit to a given investment in ensuring quality, the marketing and pricing strategy can act as a commitment device.     

Spanish air travel and the September 11 terrorist attacks: a note

This paper studies the impact of the September 11 terrorist attacks and its after-effects on Spanish airline demand. Using monthly time series data from 1980–2003, we find that September 11th resulted in an ongoing negative demand shock although smaller than that experienced in the US but particularly in relation to international passengers.     

Determinants of collateral

We estimate a comprehensive model of the determinants of collateral in loans extended to business firms. We use a panel data on a sample of bank loans to Spanish firms from 1984 to 2002. Consistent with theories that view collateral as a solution to adverse selection problems, our results provide direct evidence of a negative association between collateral and a borrower's risk. We also present evidence on previously unexplored determinants of collateral such as credit market competition, lender type, and the business cycle.     

When Do Vertical Mergers Create Value?

This paper studies the market reaction to vertical mergers and explores the many rationales for vertical integration proposed in the industrial organization literature. Abnormal returns for vertical merger announcements are positive until the late 1990s, and turn negative afterward. Acquirers suffer most of the losses. We find support for the most fundamental insight in the industrial organization literature, namely, that vertical mergers generate the greatest value when undertaken in imperfectly competitive markets. We find some evidence to support ideas of asset and site specificity, that is, creating value when market exchange is difficult. We do not find support for information‐based or price uncertainty theories.     

Is the Average Investor Smarter than the Average Euro?

In this study, we collect a unique data set of Spanish domestic equity funds for the period 1999–2006 to test the existence of the well-known “smart money” effect. Our focus is to test whether superior performance follows fund flows, demonstrating investor skills, and whether the results are robust for aggregate portfolio analysis and for individual fund analysis. Empirical evidence shows that investor abilities reported by aggregate portfolio analysis are not very evident from a fund-level perspective. This study provides two major contributions to the literature: the separate consideration of purchases and redemptions, and the proposal of a “smart investor” effect which considers investor movements instead of traditional money flows. Results show that investors’ selling decisions are less smart than their buying decisions and that investors, as individuals, are not significantly smarter than money.     

Child Labour

Objections to child labour range from its creating unfair trade advantage to its infringing children's human rights. Analysis of the responsibilities of various parties implicated in the use of child labour can lead to identifying stages in a cumulative ethical approach which is not self-defeating.
