The link between product diversification and performance among Spanish manufacturing firms: Analyzing the role of firm size

This study sheds additional light on the product diversification‐performance relationship for firms in a country having recently attained an advanced economy status in our period of analysis. We assume there will be an inverted U‐shaped relationship and use a sample of small, medium, and large Spanish manufacturing firms between 1994 and 2008. Our findings provide solid support for this assumption, and are identical when the sample consists of small, medium, and large firms and of large firms alone. Our results also suggest that the larger the firm, the higher the optimal level of diversification. Panel data models are used to control for unobservable heterogeneity and potential endogeneity problems. Copyright © 2015 ASAC. Published by John Wiley & Sons, Ltd.     

Quantifying the benefits of breaking bulk in retail operations

We explore the benefits of ‘breaking bulk’ in retail operations. Here, breaking bulk refers to delivering single units from distribution centers to retail outlets rather than the multiple units bundled together by manufacturers termed ‘case-packs’. The focus is largely on the benefits to space management at the retail level, rather than the more obvious reduction in inventory costs. Using data from the grocery industry, results indicate that retail unit profitability can be increased substantially by breaking bulk—but only if current inventory replenishment practices are changed. In essence, breaking bulk allows for either higher product variety within a store or identical variety in smaller stores. This work seeks to quantify the order of magnitude of that benefit.     

EVALUATING THE EFFICIENCY OF NONPROFIT ORGANIZATIONS: AN APPLICATION OF DATA ENVELOPMENT ANALYSIS TO THE PUBLIC HEALTH SERVICE

In this paper we have tried to evaluate the usefulness of the DEA model as a management tool when applied to the measurement of the efficiency of health centres. We have chosen the DEA model because it does not need prior specifications. This could be very useful when we lack data on costs. The overall evaluation of a number of health centres provides information on the distinctive features and comparative advantages of the most efficient ones. The information gathered could also be of great use in the selection of those centres in which operational audits should be carried out.

QARMA-Beta-t-EGARCH versus ARMA-GARCH: an application to S&P 500

Statistical performance and out-of-sample forecast precision of ARMA-GARCH and QARMA-Beta-t-EGARCH are compared. We study daily returns on the Standard and Poor’s 500 (S&P 500) index and a random sample of 50 stocks from the S&P 500 for period May 2006 to July 2010. Competing models are estimated for periods before and during the US financial crisis of 2008. Out-of-sample point and density forecasts are performed for periods during and after the US financial crisis. The results provide evidence of the superior in-sample statistical and out-of-sample predictive performance of QARMA-Beta-t-EGARCH.     

Organizational distance and use of collateral for business loans

This paper examines the effect of organizational distance (i.e. distance between the headquarters of the bank that grants a loan and the location of the borrower) on the use of collateral for business loans by Spanish banks on the basis of the recent lender-based theory of collateral [Inderst, R., Mueller, H.M., 2007. A lender-based theory of collateral. Journal of Financial Economics 84, 826–859.]. We find that, for the average borrower, the use of collateral is higher for loans granted by local lenders than by distant ones. We also show that the difference in the likelihood of collateral in loans granted by local lenders, relative to distant lenders, is higher among older and larger firms, than, respectively, younger and smaller firms. We also find that banks use lending technologies that are different for near and for distant firms, in response to organizational diseconomies.     

Strategic Moves and Organizational Survival in Turbulent Environments: The Case of Spanish Banks (1983–97)*

abstract The main purpose of this paper is to examine the effect of ‘strategic moves’ (or strategic change) on the likelihood of organizational survival in a population of firms which has undergone radical transformations in its environment. To this end, we propose and test two competitive hypotheses which are the result of two other theoretical perspectives about the consequences of strategic change: the adaptation view (classic strategic management and dynamic capabilities) and the ecological approach. While from the former, in general, it is assumed that strategic change has a positive effect on the likelihood of organizational survival, from the ecological approach, it is frequently argued that attempts at reorganization in general and strategic change in particular tend to be associated with an increase in the likelihood of organizational extinction. The sample used to test the two proposed hypotheses is the Spanish bank population over the period 1983–97. The results confirm the positive and significant effect of strategic moves (or strategic change) on the likelihood of organizational survival, in line with the conclusions of the adaptive perspective and other empirical research carried out in different settings. This paper introduces two important methodological innovations: (a) the definition and measurement of ‘strategic moves’ (or strategic change) by using a new cluster algorithm, the MCLUST; and (b) the control of the non‐observable heterogeneity using panel data models for ‘probit’ regression.     

Survival of new firms in the Brazilian franchising segment: an empirical study

This paper investigates the survival patterns of Brazilian franchising firms for the period 1994–1999. First, we considered the (percentage) survival of newly created franchisors in the following years. Survival functions were obtained by means of the Kaplan–Meier estimator for the selected sectors and they indicated sharp declines in the survival rates over time but with differential patterns across sectors. Finally, an econometric analysis based on the Cox proportional hazard model considered the explanatory variables pertaining to size, age and support regarding the legal aspects, location choice and training. The evidence indicates that the supports provided by the franchisor have a positive impact on the probability of survival of new firms, whereas there is partial evidence favoring a positive effect of firm size on survival.     

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.
