A result similar to the Odlyzko's ‘Paris Metro Pricing’

The two-stage competition is investigated in which two Internet Service Providers (ISP) choose sequentially their capacities and then their prices while facing a flow of new customers who decide to belong to one ISP or the other on the basis of a comparison of access prices and of expected congestion rates. At the equilibrium of the game a vertical differentiation between the Internet Service Providers endogenously emerges: the firm which provides the larger network has the lowest rate of congestion and the highest access price. The ISP providing the smallest network (thus the most congested) earns the larger profit. It will be noticed that the spontaneous functioning of oligopolistic competition produces a result similar to the Odlyzko's ‘Paris Metro Pricing’: at the equilibrium the two competitors propose different prices and rates of congestion, the most expensive one being also the least congested.     

Do Changes in Democracy Affect the Political Budget Cycle? Evidence from Mexico

The previous empirical literature in opportunistic election cycles attempts to identify whether there is a significant impact of the election calendar on economic policy. The econometric analysis implemented in this paper goes a step further, seeking to test whether a country's time-varying degree of democracy affects the way in which economic policy is chosen as elections approach. A simple econometric model is estimated for the case of Mexico's fiscal policy between 1957 and 1997. The estimation reveals the government's strong systematic use of public spending in infrastructure and current transfers as a means to earn votes. Most importantly, we show that the magnitude of the election cycle has been exacerbated during the country's most democratic episodes.     

The microstructure of exchange rate management: FX intervention and capital controls in Brazil

This article uses a microstructure approach to analyse the effectiveness of capital controls introduced in Brazil to counter an appreciation of the Real. Based on a rich data set from the Brazilian foreign exchange market, we estimate a reduced-form VAR to characterize the interaction of the central bank, financial and commercial customers in times of regulatory policy measures. We find that capital controls change market participants’ behaviour, and that central bank interventions elicit a significant response in financial order flow. Referring to the source of order flow, we find no direct price impact by financial flows and thus no evidence that the appreciation of the Real is driven by financial customers’ activity. Instead, commercial customers seem to be a primary driver of the Real within our model.     

The struggle for space: Past and future of the space race

This article is geared toward shedding some more light on what may be the next space race and its contours.Space flight is undoubtedly a human achievement of the second half of the 20th century, and probably the most audacious one of the past century. The space race started suddenly in the 1950s and has grown explosively during the following two decades, but decreased steadily after the 1970s. After the 1990s, however, we have seen a shy rebirth of space-related activities, when many other actors (states) entered the stage, adding up to the agonizing role of the two-actor piece that we have witnessed during the so-called Cold War.The opening years of the 21st century provided a more complex narrative for space exploration. At the start of the new millennium a new technosphere [1] emerged, dominated by what is used to be called as the Information and Communications Technologies (ICT), with the Internet playing the leading role among the bandwagon of technological novelties that appeared during the twilight of space activities. In despite of the fact that artificial satellites represent the very backbone of the global communications system, space activities seem to play a secondary role amidst the apparently accelerated rate of change concerning the technological systems of the present technosphere. But, as it is demonstrated in this paper, things are changing, and very probably a renewed space race will unfold in the coming decades.A question may be placed: what happened? Why the Earth stood still with regard to the race toward the cosmos? Answer: futurists, even prestigious ones like Herman Kahn and Arthur Clarke, did not consider the existence of socioeconomic long waves (Kondratieff waves, or K-waves for short) with their two decades long economic downturn, which has contributed to the deceleration of space-related activities.Analyzing the worldwide evolving scenario of space-related activities during the last eighty years under the framework of the succeeding K-waves and applying some technological forecasting tools, namely the logistic analysis, technological surveillance and intensive data mining, scrutinizing more than 7500 events occurred in the period 1930–2010 related with space activities, it is demonstrated that the space race like the one that we have witnessed until now is a natural growth process that has saturated at the dawn of this century. The same analysis demonstrates that a new growth process in this field might be nowadays under way with contours very different from that imagined by futurists and science fiction writers sixty years ago. Also the main trends in the usage of launching vehicles and satellites are framed and discussed in this paper.     

Firm heterogeneity and immigrant wage assimilation

This article investigates the role of job mobility in immigrant wage assimilation. I use longitudinal linked employer–employee data for Portugal to estimate the immigrant wage catch-up in log wage regressions with both individual and firm fixed effects. I show that moving to firms with higher wage premiums accounts for approximately 30% of the immigrant wage catch-up in the first years.     

Central bank disclosure as a macroprudential tool for financial stability

The Basel Capital Accord (pillar 3) states that disclosure of information (transparency) is essential to financial stability. This study analyzes, through inflation reports, the disclosure of information from the Central Bank of Brazil concerning the credit market. We consider credit risk and capital buffers as measures of financial stability in this analysis. Furthermore, in order to measure the perception of the monetary authority on the credit market, we built two indices based on the central bank’s communication on credit development. We performed a panel data analysis based on a sample of 125 banks for the period from June 1999 to September 2014 (7000 observations). The findings suggest that central bank communication regarding expectations concerning the credit market contributes to financial stability. Therefore, this kind of communication of central banks (about credit development) may constitute an important macroprudential tool to improve financial stability.     

A note on assessing the relation between CEO characteristics and stock performance: Alpha Above Replacement

Many studies examine the relation between stock performance and CEO characteristics. We approach the topic in a different way, using the alphas generated by the Fama‐French three‐factor model as the dependent variable in a CEO characteristic model. We find several traits are significantly related to alpha. CEOs who are younger, own a larger fraction of firm equity and hold a graduate degree provide greater alphas. CEOs who are also the founder of the firm deliver larger alphas. Our results provide useful information for boards assessing the performance of CEOs and considering CEO succession.     

Raising Capital in an Insurance Oligopoly Market

We consider an oligopoly market where firms offer insurance coverage against a risk characterised by aggregate uncertainty. Firms behave as if they were risk averse for a standard reason of costly external finance. The model consists in a two-stage game where firms choose their internal capital level at stage one and compete on price at stage two. We characterise the subgame perfect Nash equilibria of this game and focus attention on the strategic impact of insurers capital choice. We discuss the model with regard to the insurance industry specificities and regulation.     

Nash-equilibria in a heterogeneous oligopoly with fuzzy information

We consider a model of an oligopolistic market with heterogeneous firms and products where neither the cost nor the demand functions are common knowledge. Instead, each firm only has some vague ideas about the price strategies adopted by its competitors which is modelled by a fuzzy set. In analogy to the notion of an "equilibrium of actions and beliefs" we define and characterize a generalized Nash-equilibrium and show its existence under general conditions. Furthermore, the impact of the fuzzy information on the equilibrium outcome is analyzed by means of a comparative static analysis within a particular model framework.Received: 28 May 2002, Accepted: 25 December 2002, JEL Classification: D43, D80, L13We wish to thank Bernhard F.

Endorse or Not to Endorse: Understanding the Determinants of Newspapers’ Likelihood of Making Political Recommendations

This article investigates the determinants of newspapers’ provision for political opinion. I empirically examine the role of newspapers’ political preferences and market competition on newspapers’ decision to make endorsements. Regression results suggest that market competition turns newspapers more likely to make endorsements. Results from a simple model show that newspapers’ ideology determine their endorsements, making partisan papers more likely to make political recommendations and endorse challengers than non‐partisan newspapers.
