A switching ARCH (SWARCH) model of stock market volatility: some evidence from Latin America

We use the Markov regime-switching ARCH (SWARCH) model of Hamilton and Susmel (J Econometrics 64:307–333, 1994) to document the presence of high volatility regimes in six Latin American countries (Argentina, Brazil, Chile, Mexico, Peru, and Venezuela). We found four high volatility episodes, each associated to either a local (the Mexican crisis of 1994, the Brazilian crisis of 1998–1999, the Argentinean crisis of 2001–2002) or a worldwide financial crisis (the Asian financial crisis of 1997). However, we found that the effects of each financial crisis are short-lived and that between 2 and 4 months after each crisis, all markets return to low volatility regimes.

The Impact of Gender Quotas on Votes for Women Candidates: Evidence from Italy

To explore the impact of quotas on women's political representation, this study estimates a conditional multinomial logit for the probability of voting for men and women, utilizing data that includes all regional candidates in four Italian regions in 1995 and 2000. This regional electoral system allows voters to choose both the party and the specific candidate (open-list proportional system). The results show that the introduction of a 50 percent gender quota in candidate lists leads to a substantial increase in the probability that voters will choose women candidates, from 12 to 36 percent. Nevertheless, the probability of voting for women (36 percent) is lower than the probability for men (64 percent). Voters have a male bias in Italy. Both the district size and the political party have an effect on the probability of voting for women versus men. The more liberal the party is, the higher the probability that women receive votes.     

The changing structure of local credit markets: Are small businesses special?

In many countries consolidation in the banking industry has reduced the number of small banks and led to significant shifts in market shares; deregulation has fostered entry in local credit markets and the expansion of branch networks, increasing competition in local markets. Small businesses are believed to be more vulnerable to these changes, since they are more dependent on credit from local banks. In this paper we investigate the consequences of consolidation and entry for these borrowers compared with those for large firms. We employ a data set for Italy, which provides information on volumes of loans and bad loans by size of borrower with a detailed geographical partition. We find that mergers are followed by a temporary reduction in outstanding credit to all sizes of borrowers and by an increase in bad loans, most likely due to the reassessment of banks portfolios. Entry has a relatively persistent negative impact on credit supply to small and medium-sized firms. Our results also show that concentration, branch density and the share of branches of small banks affect the volumes of credit and bad loans of small borrowers.     

International trade and financial integration: a weighted network analysis

The authors analyse patterns of international trade and financial integration using complex network analysis. The combination of both binary and weighted approaches delivers more precise and thorough insights into the topological structure and properties of international trade and financial networks (ITN and IFN). It is found that the ITN is more densely connected than the IFN, while both types of network display a core–periphery structure. This hierarchical organization is more pronounced in financial markets, suggesting that the bulk of trade in financial assets occurs through a handful of countries acting as hubs. High-income countries are better linked and form groups of tightly interconnected nodes. This kind of structure can explain why the recent financial crisis has spread rapidly among advanced countries while reaching emerging markets only in a second phase.     

Exchange market pressure: some caveats in empirical applications

The Exchange Market Pressure (EMP) index, developed by Eichengreen et al. (1994 Eichengreen, B, Rose, AK and Wyplosz, C. 1994. Speculative attacks on pegged exchange rates: an empirical exploration with special reference to the European monetary system, NBER Working Paper No. 4898  [Google Scholar]), is widely used as a tool to signal whether pressure on a currency is softened or warded off through monetary authorities’ interventions or, rather, a currency crisis has originated. In this article we show how the index is sensitive to some assumptions behind the aggregation of the information available (exchange rates, interest rates and reserves), especially when emerging countries are involved. Specifically, we address the way exchange rate variations are computed and the impact of different definitions of the reserves, and we question the constancy of the weights adopted. These issues compound with the choice of a fixed threshold when crisis episodes are identified through the EMP index. As a result, one should exert caution in subsequent econometric analyses where a dependent binary variable is built to identify crisis periods.     

The mediating role of work engagement on the relationship between job involvement and affective commitment

This study examines job involvement and work engagement as predictors of affective commitment. Specifically, we test the proposal of Hallberg and Schaufeli (2006) that work engagement is a mediator of the relationship between job involvement and affective commitment using a survey of 405 Italian working adults. To test the model, mediation effects technique and structural equation modelling were applied to the collected data. Our hypothesis that work engagement fully mediates the relationship between job involvement and affective commitment was supported. This is the first study to demonstrate the importance of job involvement in promoting affective commitment via three dimensions of work engagement. We therefore assert that HR managers should direct their available resources to promoting job involvement and work engagement in their employees.     

Age and firm growth: evidence from three European countries

This article provides new insights into the dependence of firm growth on age along the entire distribution of growth rates, and conditional on survival. Using data from the European firms in a global economy survey, and adopting a quantile regression approach, we uncover evidence for a sample of French, Italian and Spanish manufacturing firms with more than ten employees in the period from 2001 to 2008. We find that: (1) young firms grow faster than old firms, especially in the highest growth quantiles; (2) young firms face the same probability of declining as their older counterparts; (3) results are robust to the inclusion of other firms’ characteristics such as labor productivity, capital intensity and the financial structure; (4) high growth is associated with younger chief executive officers and other attributes that capture the attitude of the firm toward growth and change. The effect of age on firm growth is rather similar across countries.     

Coase (1937) revisited: Endogenous fiat in firms and markets

Coase (Economica 4:386–405, 1937) observed that, within firms, employees are directed by fiat. Ever since it has been argued that hierarchical control and fiat are institutional attributes of firms. In contrast with this view, there is evidence that the organizational structure of many interfirm relations, from supply networks to franchising, is also hierarchical. To reconcile Coase’s insight with the evidence, I develop a model where the obligations of both a firm’s contractors and its employees cannot be enforced by courts, so they must be self-enforcing. I show that fiat, in the form of relational contracts where the agent obeys the principal in equilibrium, occurs both when the agent is an employee—so the principal owns all the assets—and when she is a contractor—so the agent owns some assets. However, the principal can give more orders to an employee (contractor) when decisions sufficiently above (close to) those that maximize the value of the contractor’s assets are optimal—for instance, because there are strong positive externalities between the assets. The model has several implications for the theory of the firm, the distinction between markets, hybrids and hierarchies, and the choice between in-house provision and outsourcing of public services.     

Intellectual property rights,imitation, and development. The effect on cross-border mergers and acquisitions

In this paper, we analyze whether the recent global process of strengthening and harmonization of intellectual property rights (IPRs) affects decisions of cross-border mergers and acquisitions (M&As). We investigate if IPRs have a differential effect across sectors of different technology content and for countries of different development level. Also, we study how imitation abilities of target countries interact with the tightening of IPRs. Using data for the post-TRIPS period (1995–2010), we estimate an extended gravity model to study the bilateral number of M&As, including a measure of the strength of IPRs systems on target countries and a set of control variables usually considered as determinants of M&As. The estimation results verify the gravity structure for M&As and show that IPRs –and enforcement– influence decisions of cross-border M&As in all sectors regardless of their technological content. However, IPRs are more important in countries with high imitation abilities and in sectors of high-technology content. Furthermore, a strengthening of IPRs leads to a larger increase of M&As in developing countries than in developed countries. These results call the attention on the possible implications for least developed economies and challenge the adequacy of a globally harmonized IPRs systems.
