Comovement among returns of the private Chilean pension system

Abstract

The measurement of comovement among economic variables is key in several areas of economics and finance. This article examines the comovement among Pension Fund Administrators (AFPs) in the Chilean private pension system from 2005 to 2016. We use several statistical methods to assess the comovement among the returns during this period. We found evidence of strong comovement among the returns of all AFPs; the higher the percentage of risk rate of the investment instrument, the higher the comovement was. The introduction of a new AFP in 2010 did not change the comovement patterns. The comovement analysis study shows that the quality attributes of the products offered by the AFPs are homogeneous, supporting the idea that concentrated markets with homogeneous products could incentivize tacit collusive behavior, which could distort the functioning of the pension market, thereby affecting the aggregate well-being of workers.     

Portfolio management with tail dependence

Many publications, that treated with Portfolio Management, were devastating for all asset allocation models in the context of portfolios. The elimination of extreme events (asymmetric or tail dependence) during the portfolio construction process can reduce the skills of asset managers to reduce risk through diversification. The copula theory allows us to calculate an alternative to measure the dependence of extreme events in assets through the index lower tail dependence. We check that the strategies with tail dependence overcame Talmud rule, the Markowitz model and the model of Tu and Zhou by simulating 1,000 portfolios with 3, 5, 10 and 20 randomly selected assets from DJIA for the period 03/1990 until 12/2016. We conclude that models of tail dependence and Markowitz had more performance ex-ante than Talmud and the Tu and Zhou model for portfolios with 3, 5, 10 and 20 assets. Tail dependence models overcome Markowitz, in terms of cumulative return, in over 60% of months considered in the analysis. The results indicate that the Talmud rule should be discarded in a context of constructing portfolios with individual stocks ahead strategies with tail dependence.     

The origins of external knowledge inflows and the impact of university technologies

This paper analyses how universities leverage knowledge coming from different technological, institutional, and geographical domains to develop technologies exerting a relevant impact for firms’ technological advancements. The analysis is based on a panel of 219 worldwide universities that filed, at least, a patent belonging to the alternative energy production sector in the period 2002–2010. Results show that using external knowledge originating in different technological and institutional domains exerts an inverted U‐shaped effect on the firms’ subsequent technological progress, while the geographical origin seems to do not exert any influence.     

The nature of Coasean property

The Coase Theorem is widely regarded as pointing to the importance of positive transaction costs for the analysis of economic institutions. Various interpretations of the Coase Theorem regard transaction costs as some set of impediments to contracting, or more broadly, as the costs of providing institutional solutions to conflicts over resource use. The abstract nature of the Coasean hypothetical tends to promote an abstract notion of property as a thin entitlement: a right in a designated person to take certain actions or derive value from a set of resource attributes. On this view, property is like a collection of tiny contracts. The property rights furnished by actual property law are much more coarse grained than this, and property is correspondingly “incomplete” for transaction costs reasons. Property and contract are substitutes in some situations, but they often are not interchangeable—because of Coasean transaction costs.     

Measuring (in a time of crisis) the impact of broadband connections on economic growth: an OECD panel analysis

Technological innovation has always been considered a major stimulus for economic growth. High-speed internet access via broadband infrastructure has undergone rapid development since the end of the 1990s, thanks to the deployment of both fixed and mobile technologies. The present study investigates the impact of fixed broadband diffusion as a technological determinant of economic growth on the basis of a panel of 23 OECD countries over 15 years (1996–2010). The time horizon chosen is suitable for verification of the causal effect on growth of the transition from traditional copper to partially fibre networks. Through implementation of a dynamic panel by using the generalized method of moments (GMM) combined with an instrumental variable (IV) two-stage approach, we found a positive correlation between broadband diffusion and economic growth, even after controlling for countries initial endowment of information and communication technologies (ICT) and for the years of economic crisis. Our main finding provides evidence, through a continuous time interpretation of our estimations, of a quantitatively relevant relationship between broadband diffusion and economic dynamics in the short, medium and long runs. Our findings may be useful to policy makers in that they permit forecasting of the benefits of further transition from broadband to ultra-wide broadband networks.     

SMEs international growth: The moderating role of experience on entrepreneurial and learning orientations

New and small firms operating in the high-tech environments need strong entrepreneurial (EO) and learning (LO) orientations to enhance international growth. Yet, the relationship between these two key strategic dimensions and foreign growth can be contingent to the entrepreneur’s individual characteristics. Bringing together elements from strategic management, organization and entrepreneurship literatures, we employ a dynamic temporal perspective considering two levels of analysis, the firm and the entrepreneur, and we apply a fixed effects pooled time-series regression on a sample of 170 firms in two periods of time (2005 and 2015). Our findings indicate that SMEs that possess greater EO and LO have higher international growth. However, previous entrepreneurial and industry-specific managerial experience of the founder/CEO positively exert their effect on these relationships. Our results have important theoretical and practical implications for entrepreneurs and policy makers operating in highly innovative sectors.     

The effect of foreign entry and ownership structure on the Philippine domestic banking market

We examine the response of domestic Philippine banks to the relaxation of foreign entry regulations that occurred in the Philippines. We find evidence that foreign bank entry is associated with a reduction in interest rate spreads and bank profits, but only for those domestic banks that are affiliated to a family business group. Foreign entry corresponds more generally with improvements in operating efficiencies, but a deterioration of loan portfolios. Overall, we conclude that foreign competition compels domestic banks to be more efficient, to focus operations due to increased risk, and to become less dependent on relationship-based banking practices.     

The “Modified Vendetta Sanction” as a method of corporate-collective punishment

Shannon Shipp argues for the Modified Vendetta Sanction as a method of corporate-collective punishment. He claims that this sanction evades the difficulties of Peter French's Hester Prynne Sanction. In this paper I argue that, though the Modified Vendetta Sanction evades the problems that Shipp poses for it, it fails to evade some of the difficulties that I pose for French's method. Moreover, there are some difficulties that plague the Modified Vendetta Sanction which do not count against the Hester Prynne Sanction. Therefore, if my analysis holds, then Shipp's method neither improves significantly on the Hester Prynne Sanction nor is unproblematic in its own right. The significance of this paper is that it foils yet another attempt by some corporate punishment theorists to establish the plausibility of a method of corporate-collective punishment. J. Angelo Corlett has authored papers on ethics, social/political philosophy, history of philosophy, value theory, epistemology and metaphysics. His papers appear in such journals as the Public Affairs Quarterly, the Journal of Business Ethics, Business & Professional Ethics Journal, the American Psychologist, Idealistic Studies, the American Philosophical Association Newsletter on Philosophy and Medicine.

Import Tariff and Exchange Rate Transmission in a Small Open Economy

ABSTRACT

We present a small open economy DSGE model with internal and external sticky prices in an incomplete exchange rate pass-through environment. Import tariff is included as another variable that affects the law of one price. The model is calibrated for the Brazilian economy, and the responses of endogenous variables to shocks in import tariff, aggregate supply, monetary policy, and foreign interest are analyzed. The long-run effect of the first shock is deterioration in the terms of trade because the exchange rate appreciation following this shock offsets the initial effect of the increase in import tariff.     

A SHOCK ABSORPTION INDEX FOR INOPERABILITY INPUT–OUTPUT MODELS

Recent disasters have underscored the importance of enhancing resilience in economic systems. In this work, we propose a novel shock absorption index, which provides a measure of the ability of an economic system to tolerate disruptions. It is assumed that there are externally defined initial levels of system failure or disruption, as well as maximum allowable levels of inoperability for each sector. The shock absorption index is defined as the largest fraction of the anticipated initial disruption that can be absorbed by the predefined robustness limits. It provides an overall measure of the robustness of an economic system towards a disruptive event, which is driven by both the economic structure and the individual robustness of different sectors. The results of two case studies illustrate policy-making insights in identifying and prioritizing risk management strategies for critical systems.
