Capital Structure in an Industry Equilibrium with Endogenous Liquidation Values

This paper investigates the interaction between financial structure,liquidation values and product market equilibrium. Liquidation values depend on how many firms are liquidated, and therefore on the industry equilibrium of capital structures and of technology choices.We show that firms using a technology with high liquidation value issue lessdebt than those with low liquidation value even if these ones may beinefficiently liquidated. With respect to the equilibrium in the industry,we obtain that even if in equilibrium all firms use the same technology,firms will use widely different capital structures.     

Toward a cross‐cultural theory of “exemplary organizations”: Evidence from Cuba

Management interest in “good companies to work for,” or “exemplary organizations,” has attracted the interest of researchers in the United States and Europe. We contribute to the literature on exemplary organizations by studying the representation of “exemplary organizations” in an unusual context, Cuba, and by inviting scholars to explore the cross‐cultural differences between what in different countries is viewed as an exemplary organization. Until now, studies on the best companies to work for have focused on companies operating in capitalistic economies. We aim to develop a better understanding of the representation of what a good place might be in an economic and ideological context that is in sharp contrast with the contexts in which this theme has been studied previously. © 2007 Wiley Periodicals, Inc.     

The disclosure of risk in financial statements

The accounting information currently issued by firms is not wholly adequate when used for decision making purposes, and within that process, for forecasting, for which additional information on risks is required. Therefore a reform of the current framework becomes necessary. Within this reform an adequate scheme and typology for the risks facing firms must be established and a set of specific risk quantification models must be designed. This paper focuses on both issues, showing all the risks that can affect firms and proposing a quantification model for each one.     

Foreign Direct Investment and Income Inequality in Southeast Asia: a Panel Unit Root and Panel Cointegration Analysis, 1990–2013

This paper examines the relationship between foreign direct investment (FDI) and income distribution in the host country as measured by the Gini coefficient. After providing some background and reviewing the extant literature, it undertakes a panel unit root and cointegration analysis that tests whether FDI has a non-linear impact on income inequality in seven selected Southeast Asian countries over the period 1990 to 2013. The paper finds strong evidence for panel cointegration using the Pedroni Augmented Dickey Fuller (ADF) and Phillips-Perron (PP) tests. Thus, it proceeds to utilize the group-mean fully modified ordinary least squares (FMOLS) procedure to generate long-run estimates that are unbiased and consistent. The FMOLS estimator is also extremely accurate even in panels with very heterogeneous serial correlation dynamics, fixed effects, and endogenous regressors. The results confirm the hypothesis that FDI inflows tend to raise income inequality in the short run but reduce it in the long run. In this study, the Gini index starts decreasing after FDI inflows as a percentage of GDP reaches 5.6. The fact that the Gini coefficient reaches its maximum at a relatively low level of FDI inflows suggests that sample countries are endowed with substantial absorptive capacity. In other words, they will shift into the new technological paradigm quickly, thus supporting pro-globalization claims that, on balance, FDI is more beneficial than harmful.     

R&D investment dynamics in agglomerations under weak appropriability regimes: Evidence from Indian R&D labs

What are the dynamics of R&D investment when firms agglomerate in environments with weak intellectual property rights protection? Specifically, do foreign and domestic firms present equal opportunities for free riding by domestic firms in such environments? We examine the impact on local firms' R&D investment from knowledge spillovers originating from co‐located foreign and domestic firms within and across industries. Building on fieldwork in India, we predict free riding by local firms on nearby foreign and local firms. Furthermore, we expect local firms to free ride more from other local firms within their industry and from foreign firms across industries. Analyzing a sample of 3,475 R&D lab investment decisions during 2003–2010 in India, we find that local firms free ride from other local firms both within and across industries.

The Causes of Urban Sprawl in Spanish Urban Areas: A Spatial Approach

This paper explores the presence of local spatial interaction on urban development patterns of Spanish urban areas and whether this interaction might be due to the strategic behaviour of neighbouring local governments. Using remote-sensing data from aerial photography and satellite imaging along with Geographic Information Systems (GIS) techniques, it studies urban development patterns across the country with unprecedented detail. The results confirm the main hypothesis that spatial interaction exists in the levels of sprawl between neighbouring municipalities, suggesting that local governments do indeed compete for the creation of new suburban settlement developments, hence promoting excessive urban sprawl.     

Samuelson and Davidson on ergodicity: A reformulation

The concept of ergodicity in economics seems to have the qualities of a shibboleth—a word or saying used by adherents of a party, sect, or belief, and usually regarded by others as empty of real meaning. It is in use by both neoclassical economics—after Samuelson (1965 Samuelson, P. A. “Proof That Properly Anticipated Prices Fluctuate Randomly.” Industrial Management Review, 1965, 6 (2), 41–49.[Web of Science ®] , [Google Scholar], p. 43), who used the term in his paper on what later became a foundation of the efficient market hypothesis—and post Keynesian economics—after Davidson, who picked up the term in order to highlight methodological differences. Considering the origin of the concept in statistical physics and its use in the topology of dynamical systems, which most economists are not conversant with, the importance ascribed to ergodicity in economic debate seems mystifying. We deconstruct the meaning of the term in the major contributions of Samuelson and Davidson. We suggest an alternative to (non)ergodicity to discuss the nature of randomness in the real world. While neoclassical theory assumes stochastic randomness, post Keynesians assume nonstochastic randomness, a term developed by the mathematician Kolmogorov (1986 Kolmogorov, A.N. “On the Logical Foundations of Probability Theory.” In K. Ito, and J.V. Prokhorov (eds.), Probability and Mathematical Statistics, Moscow, 1986, pp. 467–471. [Google Scholar], p. 467). We argue that even in an ergodic world there is a problem with the idea that stochastic randomness can be dealt with by the financial system.     

Portugal–EU Convergence Revisited: Evidence for the Period 1960–2003

This paper uses the stochastic approach to convergence to investigate whether real per capita GDP in Portugal has been converging to the EU15 average. The estimation accounts for conditional convergence, transitional dynamics and up to two structural breaks. It is found that per capita GDP in Portugal has indeed converged to the EU15 average, but the pace of convergence has not been uniform along time. In particular, a slow down in the convergence process is identified in 1974. This result depends, however, as to whether the choice of this break-date is viewed as uncorrelated with the data. No evidence of acceleration in the speed of convergence is found after EC accession, in 1986.An earlier version of this paper was presented at the Fifty-Ninth International Atlantic Economic Conference, London, England, March 9–13, 2005.
