Education for the masses? The interaction between wealth,educational and political inequalities

This paper presents a simple model of distribution dynamics, in which the distributions of wealth, education and political power are circularly endogenous. Different levels of education translate into different income and wealth levels. Political power may (or may not) vary with wealth, and in turn affects decisions on the level of public expenditure on education. Since the market for education credit is imperfect, some people might need to rely on public schooling, the quality of which depends on those expenditure levels. As a result, educational opportunities differ along the wealth distribution. The dynamic system displays multiple equilibria, some of which are characterized by a vicious circle of interaction between educational, wealth and political inequalities. These particular equilibria, which are more unequal, are also shown to be inefficient in terms of aggregate output levels. Switching equilibria may be achieved through redistribution of political power.

International Financial Liberalization, Capital Flows, and Exchange Rate Regimes: An Introduction

This introduction to a special edition of Review of International Economics summarizes a collection of articles that originated in a conference on “Is Globalization of Capital Markets a Boost or a Hindrance to Development?” that was sponsored by the Program in Economic Policy Management (PEPM) at Columbia University during 16–17 April 1999.     

Lending relationships in the interbank market

We use a unique dataset to show that relationships are an important determinant of banks' ability to access interbank market liquidity. More precisely, we find that: (i) banks with a larger reserve imbalance are more likely to borrow funds from banks with whom they have a relationship, and to pay a lower interest rate than otherwise; (ii) smaller banks and banks with more non-performing loans tend to have limited access to international markets, and rely more on relationships; (iii) relationships are established between banks with less correlated liquidity shocks. These results suggest that relationships allow banks to insure liquidity risk in the presence of market frictions such as transaction and information costs. Our analysis explicitly controls for the endogeneity of bank relationships.     

Road traffic injuries in Colombia

Road traffic injuries are a leading public health problem in Colombia. Pedestrians are the most vulnerable road users, especially in the main urban centers of Bogotá, Medellin and Cali. Data analyzed in this report include official statistics from the National Police and the National Institute of Legal Medicine and Forensic Sciences for 1996-2000, and results of a study conducted at the National University of Colombia in 2000. Methods from the Highway Capacity Manual were used for determining physical and technical variables, and a Geographical Information System tool was used for the location and spatial analysis of the road traffic crashes. Pedestrians accounted for close to 32% of injuries and 40% of the deaths from road traffic crashes. The problem of road traffic crashes existed predominately in urban areas. In the main urban centers, pedestrians constituted nearly 68% of road traffic crash victims. The high level of risky road use behaviors demonstrated by pedestrians and drivers, and inadequate infrastructure for safe mobility of pedestrians in some sections of the road network were the main contributing factors. Major improvements were achieved in Bogotá following enhancements to the municipal transport system and other policies introduced since 1995. In conclusion, policies and programs for improving road safety, in particular pedestrian safety, and strengthening urban planning are top priority.     

Is the Border Effect an Artefact of Geographical Aggregation?

The existence of a large border effect is considered as one of the main puzzles of international macroeconomics. We show that the border effect is, to a large extent, an artefact of geographical concentration. To do so, we combine international flows with intra‐national flows data characterised by a high geographical grid. At this fine grid, intra‐national flows are highly localised and dropping sharply with distance. The use of a small geographical unit of reference to measure intra‐national bilateral trade flows allows to estimating correctly the negative impact of distance on shipments. When we use sector disaggregated export flows of 50 Spanish provinces in years 2000 and 2005 split into inter‐provincial and inter‐national flows, we find that the border effect is reduced substantially and even becomes statistically not different from zero in some estimations.     

Efficiency vs. market power in retailing: Analysis of supermarket chains

The objective of this article is to analyze the relationship between market structure and performance in the Spanish retail sector. As a new contribution, this paper considers a direct measurement of efficiency, which allows us to test different hypotheses explaining profitability in the generic framework of the theories of market power vs. efficiency. The results of the empirical application on a sample of 147 supermarket chains operating in Spain find that the competitive situation that best characterizes this sector is that of the modified efficient structure. Although efficiency does contribute positively to explaining differences in profitability, market share, which would capture the effect of market power, also has a positive effect.     

Innovation dynamics and labor force restructuring with asymmetrically developed national innovation systems

The concept of National Innovation System (NIS) has gained a great deal of intellectual and practical attention over the past three decades. We present an endogenous growth model where the NIS of a country determines its accumulation of technological knowledge and the arrival rate of innovations depends on the distance from the technological frontier to the current technological development level (TDL) of the country. We show how, even within an ideal common market environment and despite the compensatory mechanism provided by migration and the advantage of backwardness enjoyed by the laggard countries, differences in TDLs among countries foster the economic stagnation of technological laggards. That is, the structural consequences derived from technological underdevelopment are persistent and not simply due to the depreciation of human capital, but to the absence of innovation incentives that follows. Numerical simulations and an empirical analysis are performed to illustrate the main results and relate them to the current European common market setting and the innovation policies of its members.     

Valuation of projects with minimum revenue guarantees: A Gaussian copula–based simulation approach

This technical note presents a numerical simulation technique to perform valuations of infrastructure projects with minimum revenue guarantees (MRG). It is assumed that the project cash flows—in the absence of the MRG—can be described in a probabilistic fashion by means of a very general multivariate distribution function. Then, the Gaussian copula (a numerical algorithm to generate vectors according to a prespecified probabilistic characterization) is used in combination with the MRG condition to generate a set of plausible cash flow vectors. These vectors form the basis of a Monte Carlo simulation that offers two important advantages: it is easy to implement and it makes no restrictive assumptions regarding the evolution of the cash flows over time. Thus, one can estimate the distribution of a broad set of metrics (net present value, internal rate of return, payback periods, etc.). Additionally, the method does not have any of the typical limitations of real options–based approaches, namely, cash flows that follow a Brownian motion or some specific diffusion process or whose volatility needs to be constant. The usefulness of the proposed approach is demonstrated with a simple example.     

A dynamic model of entrepreneurship with borrowing constraints: theory and evidence

Does wealth beget wealth and entrepreneurship, or is entrepreneurship mainly determined by an individual’s ability? A large literature studies the relationship between wealth and entry to entrepreneurship to inform this question. This paper shows that in a dynamic model, the existence of financial constraints to the creation of businesses implies a non-monotonic relationship between wealth and entry into entrepreneurship: the probability of becoming an entrepreneur as a function of wealth is increasing for low wealth levels—as predicted by standard static models—but it is decreasing for higher wealth levels. U.S. data are used to study the qualitative and quantitative predictions of the dynamic model. The welfare costs of borrowing constraints are found to be significant, around 6% of lifetime consumption, and are mainly due to undercapitalized entrepreneurs (intensive margin), rather than to able people not starting businesses (extensive margin).     

An analysis of changes to a team-based incentive plan and its effects on productivity,product quality,and absenteeism

Using data from three production units of a large manufacturing plant that employs production teams in its assembly operations, this paper examines how changes made to an existing team-based incentive plan affects labor productivity, product quality, and worker absenteeism. The firm switched from a piece-rates contract and an attendance bonus and instituted a two tier incentive plan comprising two different but complementary performance-based bonus schemes: one tier based on individual team performance and the other tier on plant-wide performance. The incentives were introduced concurrently with management control initiatives intended to facilitate cooperation and monitoring among the teams. I find significant productivity gains and improvements in quality and absenteeism associated with the new incentive plan. These findings underscore two important points that have not been emphasized in existing empirical studies of incentive pay: incentive contracts for teams generate superior performance using combination of incentives, and the need to introduce organizational changes to facilitate cooperation and peer monitoring in tandem with incentive pay to capture greater incentive effects in team production.
