Endogenous growth and property rights over renewable resources

We study how different regimes of access rights to renewable natural resources – namely open access versus full property rights – affect sustainability, growth and welfare in the context of modern endogenous growth theory. Resource exhaustion may occur under both regimes but is more likely to arise under open access. Moreover, under full property rights, positive resource rents increase expenditures on manufacturing goods and temporarily accelerate productivity growth, but also yield a higher resource price at least in the short-to-medium run. We characterize analytically and quantitatively the model׳s dynamics to assess the welfare implications of differences in property rights enforcement.     

Informality,enforcement and growth

This paper develops a two-sector growth model with formal and informal sectors for an economy that cares about redistribution and illustrates its relationship with the enforcement level. The technology gap and labour rigidity explicate the duality. The state can tax the formal sector to subsidise informal income and finance public infrastructure. Alternatively, enforcement, which is costly and corresponds to a variety of discrete components from the security of property rights and integrity of contracts to control of corruptions, can be chosen to favour the formal sector and discourage the informal sector. It is observed that weaker enforcement required to accommodate some degree of informality, which releases tax burden from the formal sector needed for redistribution, can accelerate growth rate. However, sufficiently weaker enforcement dampens the formal sector expansion and growth rate. The growth rate registers an inverted-U shaped relationship against the enforcement level. The optimum enforcement can, however, be higher without formal labour union and subsidisation. This must be higher for welfare maximisation than that of growth rate, especially when the consumer cares about the quality of enforcement.     

On the Terms of Trade and Sectoral Reallocations

A commonly held view is that a small open economy adjusts to a negative external shock by switching both expenditure and resources toward the domestic traded goods sector. We show that, when both labor and imported inputs are used as factors of production, the average labor intensity in the nontraded sector may increase substantially with a decline in the terms of trade. This can lead to an internal transfer of labor into the nontraded sector, and an improvement in the trade balance even with a decline in traded sector output. This result depends on a combination of a high elasticity of substitution across nontraded varieties and large differences in labor intensities in the production of nontraded varieties. Our analysis suggests that intersectoral labor flows are not necessarily a good measure of an economy's flexibility, and that intersectoral resource reallocation and expenditure‐switching can move in opposite directions.     

Structural Change,Expanding Informality and Labor Productivity Growth in Russia

Strong growth, intensive structural change, and expanding informality have characterized many developing and emerging economies in recent decades. Yet most empirical investigations into the relationship between structural change and productivity growth overlook informality. This paper includes the informal sector in an analysis of the effects of structural changes in the Russian economy on aggregate labor productivity growth. Using a newly developed dataset for 34 industries covering the period 1995–2012 and applying three alternative approaches, aggregate labor productivity growth is decomposed into intra-industry and inter-industry contributions. All three approaches show that the overall contribution of structural change is growth enhancing, significant, and decreasing over time. Labor reallocation from the formal sector to the informal sector tends to reduce growth through the extension of informal activities with low productivity levels. Sectoral labor reallocation effects are found to be highly sensitive to the methods applied.     

Opening the Pandora's box? Trade openness and informal sector growth

This article constructs a labour transition model combining the features of job loss and job creation in the formal sector of an economy. The theoretical model examines the impact of trade liberalization on net job transition from formal to informal sector. In the light of our model we establish certain pre-conditions based on simulations under which trade liberalization is accompanied by rising informal sector. The model outcome conforms to the empirical evidence of rising informality with openness which we find in 18 Central Eastern European and Former Soviet Union countries.

Trade Reform and Informal Wages

When trade reform contracts protected formal sectors in developing countries and the formal workers move to the informal sector for employment, does that reduce informal wages? Using a 2 × 2 Heckscher–Ohlin–Samuelson (HOS) structure with formal–informal production organization for the same commodity, we show that a tariff cut in the import‐competing sector increases both informal wage and employment under very reasonable assumptions. An increase in the price of the export commodity will also increase informal wages, although aggregate informal employment unambiguously falls even if the informal export sector is labor intensive. Furthermore, the formal–informal segmentation of each sector opens up an interesting, hitherto unexplored, possibility that the informal export sector may contract despite a price increase in this sector. Change in the overall size of the export sector is also ambiguous and conditional on the relative strengths of changes in these two segments.     

Sectoral Selection and Informality: a Nicaraguan Case Study

Using microdata from the 1998 and 1993 Nicaraguan Living Standards Measurement Survey, this paper analyzes the relative size and attractiveness of formal and informal sector employment. Switching regression models of the formal/informal sector employment choice indicate that education across years and gender are the primary determinants of formal sector participation. Furthermore, the formal sector is characterized by positive selection. The results for the informal sector are less definitive, but are also suggestive of positive selection. These findings imply that the informal and formal sectors in Nicaragua contribute positively to the overall economy by attracting those individuals best suited for (in)formal sector employment.     

Resource abundance and regional development in China1

Over the past several decades, China has made tremendous progress in market integration and infrastructure development. Demand for natural resources has increased from the booming coastal economies, causing the terms of trade to favour the resource sector, which is predominantly based in the interior regions of the country. However, the gap in economic development level between the coastal and inland regions has widened significantly. In this paper, using a panel dataset at the provincial level, we show that Chinese provinces with abundant resources perform worse than their resource‐poor counterparts in terms of per capita consumption growth. This trend that resource‐poor areas are better off than resource‐rich areas is particularly prominent in rural areas. Because of the institutional arrangements regarding property rights of natural resources, most gains from the resource boom have been captured either by the government‐ or state‐owned enterprises. Thus, the windfall of natural resources has more to do with government consumption than household consumption. Moreover, in resource‐rich areas, greater revenues accrued from natural resources bid up the price of non‐tradable goods and hurt the competitiveness of the local economy.     

Trade and Renewable Resources in a Second Best World: An Overview

We provide an overview and introduction to the emerging field of trade and renewable resources, and discuss the potential impact of trade liberalization on welfare and resource conservation. A key factor determining the effect of trade reform is the institutional context or property rights regime, and our survey is organized such that it loosely follows the development of new insights with respect to institutions in this literature. This implies a transition from the benevolent planners model to the polar opposite benchmark of open access in the 1990s. Currently the pendulum is swinging back towards management and regulation, but institutions are treated as endogenous. We discuss and compare various key models in some detail and search for common ground between protagonists and antagonists of free trade.

INTRANATIONAL AND INTERNATIONAL KNOWLEDGE FLOWS: EFFECTS ON THE FORMAL AND INFORMAL SECTORS

This article studies the effects of international and intranational knowledge flows. Contributions include comparing the effects of knowledge flows on the formal and informal sectors and determining multilateral spatial spillovers of innovation. Results show that formal entrepreneurs respect intranational intellectual property rights, but benefit from international spillovers, especially from patents granted. In contrast, informal entrepreneurs somewhat respect intranational patents granted, but not patent applications and citations. International spillovers to the informal sector are mainly from patents granted. Spillover magnitudes are greater internationally than intranationally, and greater in the informal sector than the formal sector (except for trademarks). (JEL O33, L26, K42)     

International trade and terrestrial open-access renewable resources in a small open economy

Abstract .  In this paper, I investigate the effects of trade liberalization and policies on deforestation by extending a small open economy model with open-access renewable resources developed by Brander and Taylor (1997a) . I endogenize the carrying capacity of the resource. I find, unlike Brander and Taylor, that trade liberalization may increase the forest stock in the resource-abundant country and may decrease the forest stock in the resource-scarce country. Moreover, the policies primarily aimed at protecting forests, such as import restrictions by importing countries and forest certification for well-managed forests, may have perverse effects on the forest stock.

Tax collection,the informal sector,and productivity

An important determinant of informality in a country is its tax enforcement capacity, which some authors argue further distorts the decisions of firms and creates inefficiency. In this paper, I assess the quantitative effect of incomplete tax enforcement on aggregate output and productivity using a dynamic general equilibrium framework. I calibrate the model using data for Mexico, where the informal sector is large. I then investigate the effects of improving enforcement. I find that under complete enforcement, Mexico's labor productivity and output would be 19% higher under perfect competition and 34% higher under monopolistic competition. The source of this gain is the removal of the distortions induced by incomplete enforcement of taxes. These distortions affect the economy in three ways: by reducing the capital–labor ratios of informal establishments; by allowing low-productive entrepreneurs to enter; and by misallocating resources towards low-productive establishments. As a result, TFP and capital accumulation are reduced, and hence output. I decompose the gains following the guidelines of five leading papers in the literature of resource misallocation across plants. I isolate the effects of pure factor misallocation, distorted occupational choices, capital accumulation, and complementarities. I also study marginal improvements in enforcement and find that there is an inverted-U relationship between the size of the informal sector and output. This reflects the fact that improving enforcement entails a tradeoff: more taxes vs. fewer distortions.     

Labor markets and productivity in developing countries

In middle-income countries, the informal sector often accounts for a substantial fraction of the urban labor force. We develop a general equilibrium model with matching frictions in the urban labor market, the possibility of self-employment in the informal sector, and scope for rural–urban migration. We investigate the effects of labor market institutions, different types of growth, and company taxes on labor market outcomes and aggregate productivity. We quantify these effects by calibrating the model to data for Mexico, and show that matching frictions can lead to a large informal sector when formal sector workers have substantial bargaining power.     

Education and earnings in urban West Africa

Using a series of comparable labor force surveys in urban West Africa, we estimate the private returns to education among representative samples of workers in seven economic capitals (Abidjan, Bamako, Cotonou, Dakar, Lome, Niamey and Ouagadougou). The data allow us to provide a unique cross-country comparison using rigorously the same variables and methodology for each country. We tackle the issues of endogenous sector allocation (public, formal private and informal sectors) and endogeneity of the education variable in the earnings functions. We find that the returns to schooling are most often enhanced once an endogenous education variable is accounted for. This effect holds particularly true in the informal sector. In most West African cities of our sample, the public sector gives more value to education, followed by the formal private sector and then the informal sector. We also shed light on convex returns to education in all the cities and sectors, including in informal activity. More generally, a major contribution of this paper is to provide evidence of significant effects of education on individual earnings in the informal sectors of the West African cities, even at high levels of schooling.     

Job search and mobility in developing countries. Theory and policy implications

A labor market model is developed in which the formal sector is characterized by search frictions whereas the informal sector is competitive. We show that there exists a unique steady-state equilibrium in this dual economy. We then consider different policies financed by a tax on firms' profits. We find that reducing the unemployment benefit or the firms' entry cost in the formal sector induces higher job creation and formal employment, reduces the size of the informal sector but has an ambiguous effect on wages. We also find that an employment/wage subsidy policy and a hiring subsidy policy have different implications. In particular, the former increases the size of the informal sector while the latter decreases it.     

Property rights,mobile capital,and comparative advantage

Recent papers show that imperfect property rights to a natural resource – a sector-specific factor–can be a source of comparative advantage. In these models, weaker property rights attract labor–the only mobile factor – to the resource sector, increasing the country's comparative advantage for that sector. If capital in addition to labor is mobile, and if the benefits of capital are non-excludable or if the degree of property rights is endogenous, a deterioration of property rights has ambiguous effects on comparative advantage and on the equilibrium wage/rental ratio.     

The Financial Resource Curse*

In this paper, we present a model of the financial resource curse (i.e., episodes of abundant access to foreign capital coupled with weak productivity growth). We study a two‐sector (i.e., tradable and non‐tradable) small open economy. The tradable sector is the engine of growth, and productivity growth is increasing with the amount of labor employed by firms in the tradable sector. A period of large capital inflows, triggered by a fall in the interest rate, is associated with a consumption boom. While the increase in tradable consumption is financed through foreign borrowing, the increase in non‐tradable consumption requires a shift of productive resources toward the non‐tradable sector at the expenses of the tradable sector. The result is stagnant productivity growth. We show that capital controls can be welfare‐enhancing and can be used as a second‐best policy tool to mitigate the misallocation of resources during an episode of financial resource curse.     

Tanzanian formal sector workers' participation in informal production

A theoretical model is developed explaining formal sector workers participation in the informal sector. A reduced-form informal sector participation function is derived from a specific utility function, a specific informal sector production function, and a specific informal sector earnings function. The participation function can be estimated consistently, and provides a solution to the problem that informal sector ‘wages’ in developing countries are hard to observe. A sample of Tanzanian formal sector workers is used to estimate the participation function. A majority of Tanzanian formal sector workers participate in informal production. Participation in informal production is inversely related to household income, to living in Dar es Salaam, and to being a mother with small children. Participation is positively related to age, and multiple-job-holding seems to play a very different role in the transition from work to retirement in Tanzania compared to industrialized countries.
