A dynamic general equilibrium model of pollution abatement under learning by doing

In 2013, Beladi et al. constructed a dynamic general equilibrium model of pollution, and characterized a steady-state equilibrium. In this paper, we extend Beladi et al.’s model to an even more general model in which the pollution abatement costs under learning by doing are taken into account. In our model, the instantaneous abatement costs depend on both the rate of abatement and the experience of using a technology. Our objective is to apply optimal control theory to investigate the dynamic general equilibrium model of pollution abatement, and derive the steady-state equilibrium properties and optimal levels of emission permits and pollution treatment.     

Rent Seeking Behavior in Transition Countries: The Case of Romania

This paper points out, in the changing institutional setting of transition in Romania, Some relevant factors influencing economic actors to behave in a way that pushes them to devote resources to unproductive goals, rather than to embark on activities that add economic and social value. The theoretical insights offered in the literature of rent seeking are applied to the issues of transition. A mathematical model of a rent seeking economy is presented, analyzing the influence of interest groups activity on the overall income of the economy. Some examples of rent seeking behavior that severely hamper the economic efficiency are illustrated for the case of Romania. The conclusion is that, in appreciating the progress in transition, the reduction in rent seeking is an important factor to be taken into consideration.     

Environmental regulation of technically inefficient firms

This paper presents a model in which a technically inefficient firm is responsible for the emissions of pollutants. We derive second-best regulatory schemes (tax and quota) assuming that the firm’s technical efficiency is unknown to the regulator.     

Corporate Restructuring in Japan Part I: Can M‐Form Organization Manage Diverse Businesses?

The purpose of this paper is to examine the recent organizational restructuring in Japan in the framework of organizational economics, assuming that the product/market portfolio of the firm is fixed. How does a firm set about organizing its internal divisions? I first summarize some stylized facts on corporate diversification strategy and multi‐divisional (M‐form) organization in large Japanese firms from different perspectives. I then analyse the problem of choosing an organizational form. In particular, I argue that, precisely because of its related diversification, the multi‐business Japanese firm adopting the M‐form finds it difficult to differentiate its diverse businesses internally.     

Estimating efficiency spillovers with state level evidence for manufacturing in the US

Unit specific effects are often used to estimate non-spatial efficiency. We extend such estimators to the case where there is spatial autoregressive dependence and introduce the concept of spillover efficiency. Intuitively, we present an approach to benchmark how successful units are at exporting and importing productive performance to and from other units.     

Supply and quality choices in private child care markets: Evidence from São Paulo

Many developing countries have adopted the market approach for expanding the supply of child care, but little is known about the economic behavior of independent providers. Drawing on uniquely rich census data on child care providers from São Paulo, we document three main facts: (1) the stock of private suppliers is considerably larger in high-income city districts; (2) the quality of private provision – as measured by teachers' schooling, group size and equipment – is highly heterogeneous across space and increases systematically with local household income; and (3) a considerable share of centers operates below recommended (but not regulated) quality standards, especially in low-income districts. These findings are consistent with a model of endogenous entry and quality choices by heterogeneous providers. Market-driven heterogeneity in the quality of provision across space is an important consideration for the design of regulations in child care markets.     

Foreign direct investment in services and manufacturing productivity: Evidence for Chile

This paper examines the impact of substantial foreign direct investment (FDI) inflows in producer service sectors on the total factor productivity (TFP) of Chilean manufacturing firms. Positive effects are obtained in firm fixed effects instrumental variables regressions and show that forward linkages from FDI in services explain 7% of the observed increase in Chile's manufacturing users' TFP. Our findings also suggest that service FDI fosters innovation activities in manufacturing. Moreover, we show that service FDI offers opportunities for laggard firms to catch up with industry leaders.     

Interdependence in multinational production networks

Abstract Most multinational firms today operate multilateral production networks. Most existing empirical analyses, however, have focused on firms’ choice between producing at home and investing overseas. This paper uses detailed French multinational subsidiary data to examine the effect of existing production networks on multinationals’ entry decisions. The paper finds strong horizontal and vertical interdependence across multinationals’ foreign production locations, but little interdependence between home and foreign production when third‐country effects are taken into account. This result constitutes a sharp contrast to the conventional emphasis and highlights the importance of investigating foreign direct investment in the context of multinational production networks.     

The determinants and impact of telecommunications reforms in developing countries

This paper has two related objectives. First, it seeks to identify the key determinants of some policies that have been at the heart of the reforms of the telecommunications industry in developing countries, namely, liberalization, privatization, and the (re)structuring of regulation. Second, it attempts to estimate the extent to which these policies have translated into actual deployment of telecommunications infrastructure. This simultaneous investigation is conducted by means of an econometric analysis of a 1985-1999 time-series-cross-sectional database on 86 developing countries. Sectoral as well as institutional and financial factors are found to be important determinants of the actual reforms implemented. We uncover a positive relationship between the decision to introduce competition in the digital cellular segment and the growth of the fixed-line segment, suggesting that these two segments have benefited from each other. We also find that countries facing increasing institutional risk and financial constraints are more likely to introduce competition in the digital cellular segment and to privatize the fixed-line incumbent, these policies being economically attractive to both investors and governments. In turn, these policies are those that enhance the deployment of fixed-line infrastructure. In contrast, competition in the analogue cellular segment and the creation of a separate regulator seem to be relatively less attractive policies as they are found to be less likely to be introduced in countries facing increasing institutional risk and budget constraints. Their impact on fixed network deployment is found to be negative or non significant.     

How does employment protection legislation influence hiring and firing decisions by the smallest firms?

This paper examines the impact of employment protection legislation (EPL) on hiring decisions by own-account workers and firing decisions by very small firms (one to four employees). Using data from the EU-15 countries, our results show that the strictness of employment protection legislation is negatively related to both these types of decisions, and hence, to labour mobility among the smallest firms. This new evidence may be useful for governments aiming to create a more enabling macro-environment for employment and productivity growth.     

Mechanism design with collusive supervision

We analyze an adverse selection environment with third party supervision. The supervisor is partly informed of the agent's type. The supervisor and the agent collude while interacting with the principal. Contracting with the agent directly and ignoring the presence of the supervisor constitutes the no-supervision benchmark. We show that delegating to the supervisor reduces the principal's payoff compared to the no-supervision benchmark under a standard condition on the distribution of the agent's types. In contrast, if the principal contracts with both the agent and the supervisor, there exists a mechanism that improves the principal's payoff over the no-supervision payoff.     

The benefits of central bank's political independence

We consider a two-tier model of monetary policy where the central banker is both subject to the explicit influence of elected political principals through contracts and the implicit influence of interest groups willing to capture monetary policy. We analyze the impact of granting independence to the central banker on the scope for capture and the agency costs of delegating the monetary policy to a central banker. Political independence increases those agency costs but significantly stabilizes the politically induced fluctuations of inflation and improves ex ante social welfare.     

Infrastructure privatization and changes in corruption patterns: The roots of public discontent

This paper offers a theory of how the degree of corruption that prevails in a society responds to changes in the ownership structure of major public service providers. We show that there are cases in which privatization, even though it fosters investments in infrastructure, also opens the door to more corruption. The public dissatisfaction towards privatization is then crucially affected by the changes in the degree and pattern of corruption. Our model thus helps understand the seemingly paradoxical situation prevailing in Latin America, where most studies find that privatizations have been efficiency-enhancing and have fostered investments and, at the same time, popular dissatisfaction with the process is extremely high, especially among the middle class. We show that this line of explanation is consistent with the evidence from surveys in the region.     

Modelling cost complementarities in terms of joint production

Cost complementarities arise from synergies in the production of heterogeneous goods. It is shown that synergies can be accounted for in terms of shared public inputs (roughly) if and only if synergies decrease as the scope of production increases. This case of “substitutive” synergies is argued to be typical. The key technical tool is a novel interpretation of conjugate Moebius inversion in terms of higher-order differences.
