Efficient interconnection charges and capacity-based pricing

Capacity-based interconnection (CBI) prices vary exactly with the costs a network provider incurs when supplying an interconnecting party. That is, they equal incremental costs, rather than being averaged over any output measure. We argue such prices (1) are as practicable and more efficient than per minute rates based on long run incremental cost, (2) are more efficient than bill and keep, and (3) with mark-ups for cost recovery, are a practical and relatively efficient means of pricing wholesale interconnection services, being well-suited to both circuit and packet-based networks.

Labour Market Adjustments to Exchange Rate Fluctuations: Evidence from Canadian Manufacturing Industries

This paper provides some of the first empirical evidence on labour market adjustments to exchange rate movements in Canadian manufacturing industries. Controlling for endogeneity using generalized method of moments estimation, it is found that during the 1981–1997 period, exchange movements have a substantial impact on labour input and that this impact has grown over time as the manufacturing industries have become more exposed to trade. In contrast, the exchange rate effect on real wages is estimated to be virtually zero for all manufacturing industries.

Trade policy and specialization in developing countries

This paper examines the impact of trade policy on specialization patterns in ten Latin American countries over the period 1985–1998. These countries are natural case studies because in the last decades they implemented comprehensive trade liberalization programs, both generally and preferentially, starting from relatively high tariff protection levels. Our econometric results suggest that reducing own most favored nation tariffs is associated with increasing manufacturing production specialization. Furthermore, we find that preferential trade liberalization and differences in the degree of unilateral openness have resulted in increased dissimilarities in manufacturing production structures across countries. These results are robust across specialization measures and estimation methods.

Saving–investment Correlations in Response to Monetary Policy Shocks: New Insights into the Feldstein–Horioka Puzzle?

In this paper, it is argued that the observed high positive correlation between national savings and investment which is found in the data can in part be explained by shocks to monetary policy. This hypothesis, which is established by reviewing some empirical findings, is tested in a two-country DSGE-model framework in the tradition of the New Open Economy Macroeconomics. The simulation results obtained support the idea that shocks to monetary policy might contribute to the explanation of the Feldstein-Horioka puzzle.

Supporting the Endogenous Relationship Between Well-Being and Employment for US Individuals

We test the existence of an endogenous relationship between well-being and employment for US individuals. To that end, we use a simultaneous equation generalized Probit model applied to four recent waves of the National Health Interview Survey (1997–2000). Our results do not enable us to accept the hypothesis that there is a significant effect from employment status to subjective well-being. In contrast, we provide evidence that suggest that well-being is positively correlated to the probability of having a job.

The effect of globalization on union bargaining and price-cost margins of firms

In recent years, Europe has witnessed an accelerated process of economic integration. This paper analyzes how increased economic integration has affected labor and product markets. We use a panel of Belgian manufacturing firms to estimate price-cost margins and union bargaining power and show how various measures of globalization affect them. Import competition puts pressure on both markups and union bargaining power, especially when there is increased competition from low wage countries. This suggests that increased globalization is associated with a moderation of wage claims in unionized countries, which should be associated with positive effects on employment.

A note on why more West than East German firms export

Germany is one of the most important exporters of manufacturing goods in the world, but by far not all manufacturing firms in Germany are exporters, and there is a remarkable gap between the share of exporters in all manufacturing firms between West Germany and East Germany. While in West Germany in 2004 about two in three manufacturing plants were exporters, fourteen years after re-unification this share was less than fifty percent in the former communist East Germany. Given that exports play a key role in shaping business cycles and growth in Germany, and the much higher unemployment in East compared to West Germany, promotion of exports by East German firms figure prominently on the policy agenda. However, the reasons for the large difference in the propensity to export between East and West German firms are not yet well understood, not least due to a lack of comprehensive micro data. Using unique new data and a recently introduced non-linear decomposition technique this paper shows that the huge difference in the propensity to export between West and East German plants can only partly be explained by differences in firm size, productivity, and technology intensity.

The Impact of the Earned Income Tax Credit on Poverty: Analyzing the Dimensions by Race and Immigration

This paper analyzes the effectiveness of the Earned Income Tax Credit (EITC) on poverty transitions, with an emphasis on native-born African–Americans and immigration. A probit model is estimated using data from the Current Population Survey (CPS), which evaluates the impact of EITC participation and immigration on transitions out of poverty. The EITC is found to be a useful tool in combating poverty and is effective for African–Americans, though only for women. More importantly, the results show that the implementation of state-level EITCs can mitigate the adverse effects of immigration for native-born African–Americans.

International mixed duopoly and strategic commitments

This paper examines an international mixed model in which a social-welfare-maximizing domestic public firm competes against a profit-maximizing foreign private firm. First, the public firm can adopt either a lifetime employment contract or a wage-rise contract as strategic commitments. Second, the foreign private firm decides whether or not to enter the market. Third, if the foreign private firm enters, each firm independently chooses its actual output, while if the foreign private firm does not enter, the public firm acts as a monopolist. The paper shows the equilibrium of the international mixed model.

Non-traded Goods,Technical Progress and Wages

We use a general equilibrium model of trade to show that technical improvement may indeed cause a fall in the wages of unskilled workers. Under some modest conditions, the wages of skilled workers may go down too.

Live or Let Die? Alternative Routes to Industry Exit

Each year around 8% of Swedish manufacturing firms leave an industry. Of the exit routes available, the least likely is firm closure. Firms are more likely to merge, become acquired or switch to a new industry. We investigate the importance of a range of firm and industry characteristics for the exit decision of Swedish firms from 1980–1996. From our analysis two patterns are evident. First, firms that close down appear to be the most distinct compared to those that remain within the sector. Second the same characteristics can have quite different associations with different exit strategies.

Productivity response to reduction in trade barriers: evidence from Turkish manufacturing plants

We examine the effects of trade policy changes on the evolution of productivity in the Turkish manufacturing industry. Plant level productivities are estimated for the 1983–1996 period following the procedure of Olley and Pakes. Industry averages indicate that productivity gains are largest in import-competing industries with highest gains reaching 8% per year during periods of rapid decline in protection rates. We find that productivity improvements resulting from declining protection rates are statistically significant and economically important, especially in import-competing sectors. More importantly, productivity improvements due to declining protection rates increase with the plant size.

Trade in Capital Goods and International Co-movements of Macroeconomic Variables

This paper contributes to the ongoing debate on the causes of international co-movements of macroeconomic variables. In particular, existing real business cycle models predict cross-country consumption correlations to be higher than in the actual data, cross-country output correlations to be lower than in the actual data, and cross-country consumption correlations to be relatively higher than the output correlations. We show that cross-country correlations of consumption, investment, employment and output predicted by a standard international real business cycle model are highly sensitive to the share of capital goods in total trade. Our calibrated model shows that when capital goods account for a share of total traded goods greater than 50%, the apparent discrepancy between the data and the simulations is resolved.

Peer Effects and Cigarette Use Among College Students

This study adds to the collegiate substance use literature by measuring the magnitude of peer effects upon individual cigarette use. The study employs data from the 2001 Harvard School of Health College Alcohol Survey to construct this peer effect measure and to study the effect of other variables upon a university student’s decision to smoke. The main finding of this paper is that moving a student from a university where no students smoke to an institution where 25 percent of the population smokes increases that student’s probability of smoking by 10.71 percent. The results of this paper suggest the potential for universities to institute student-led, anti-smoking organizations.

Are Illegal Drugs Inferior Goods in the US?

Using data from the National Survey on Drug Use and Health, evidence of income inferiority in illegal drug consumption is presented. This is done by estimation of binary choice probit models with endogenous regressors. The endogeneity of income with regard to drug consumption is considered and the more efficient three-stage least squares procedures have been implemented. In general, the results indicate that accounting for endogeneity improves results on income inferiority with regard to drug consumption. An implication of this study is that some form of income distribution policies towards the poor might be more effective in controlling substance abuse. It also points out the regressive nature of the government’s substance abuse program.

Policy coordination in East Asia and across the Pacific

In this paper, we construct a macro-econometric model that describes the economic activity in the Asia-Pacific area and provide quantitative insights into the recent policy debates on monetary and currency coordination among the East Asian economies. The model includes a wide variety of monetary and currency policy rules that the East Asian economies adopt and allows for one country's policymaking to have substantial effects on foreign countries. We apply the model to three current policy issues: (1) the desirability of currency basket pegs in East Asia, (2) the anticipated effects of China's currency policy reform, and (3) the non-negativity constraint on Japanese nominal interest rates. The simulation analyses show the external economy effects of policy rules quantitatively and suggest the difficulty of monetary and currency policy coordination among the East Asian economies.

An Exploration of Asset Returns in a Production Economy with Relative Habits

This paper explores asset returns in a production economy with habit forming households. We show that a model with capital adjustment costs and relative habits is consistent with salient financial facts, such as the equity premium, the market price of risk, and the riskfree interest rate. These predictions are not at odds with good business cycle predictions. In the model, economy investment is strongly procyclical and more volatile than output, which in turn is more volatile than consumption. Moreover, consumption growth is positively autocorrelated and negatively (positively) correlated with future (past) stock returns.

Devaluation,Debt, and Default in Emerging Economies

We explore the interactions between exchange rate and fiscal policy, and default on external debt. Exchange rate policy affects the supply of short-term debt facing the government. Under a conventional soft peg, it can be optimal for the government to set the exchange rate at a level in which partial default occurs. In this case multiple equilibria exist, with one featuring high interest rate, overvalued exchange rate, low level of output, and default. Default is also an equilibrium under a hard peg, precisely because devaluation is not an option. Under a hard peg, however, there is a unique equilibrium.

International Risk Sharing and Government Moral Hazard

This paper analyzes incentive problems caused by international risk sharing. They arise because international risk sharing contributes to the insurance of domestic consumption and thus lowers governments’ incentives to increase output. We show that the resulting distortions can lead to substantial efficiency losses. Complete risk sharing is, therefore, undesirable and the optimal degree of risk sharing may be low. Furthermore, we show that households’ risk sharing decisions are socially inefficient and are effectively maximizing government moral hazard. As a result, financial innovation and integration may reduce welfare by increasing households’ risk sharing opportunities.

Non-Keynesian Fiscal Adjustments? A Close Look at Expansionary Fiscal Consolidations in the EU

This paper analyses the characteristics of episodes of fiscal consolidation in the EU exhibiting non-Keynesian features, i.e., followed by an improved growth performance. Roughly half of the episodes of fiscal consolidations that have been undertaken in the EU in the last 30 years have been followed by higher growth. Probit regressions indicate that the consolidations that turned out to be expansionary were more likely started in periods with output below potential and based on expenditure cuts rather than on tax increases. These results appear quite robust with respect to the criteria used to identify the consolidation episodes and to classify such episodes as expansionary.
