The informal economy and the growth of small enterprises in Russia1

This article uses Russian regional data to estimate the determinants of the informal economy and to examine the relationship between the informal economy and the growth of legally registered small private enterprises during the transition period. After obtaining an estimate of the size of the informal economy in each Russian region from 1992 to 1999, an analysis is performed to find whether reform progress and institutional qualities account for the informal economy. An evaluation of the links between the informal economy and the growth of small enterprises within Russia is then carried out. The findings suggest that Russia's informal economy resulted from a delay in reform and low qualities of institutions. It was found that the growth of small enterprises is positively affected by the informal economy. These results imply that the informal economy helped entrepreneurial activities to grow in the face of government failure, but these informal activities tend to become official over time.     

Informality and Long‐Run Growth

One of the most salient features of developing economies is the existence of a large informal sector. In this paper, we use quantitative theory to study the dynamic implications of informality on wage inequality, human capital accumulation, child labor, and long‐run growth. Our model can generate transitory informality equilibria or informality‐induced poverty traps. Its calibration reveals that the case for the poverty‐trap hypothesis arises: although informality serves to protect low‐skilled workers from extreme poverty in the short run, it prevents income convergence between developed and developing nations in the long run. Then we examine the effectiveness of different development policies to exit the poverty trap. Our numerical experiments show that using means‐tested education subsidies is the most cost‐effective single policy option. However, for longer time horizons, or as the economy gets closer to the poverty trap threshold, combining means‐tested education and wage subsidies is even more effective.     

RE‐EXAMINATION OF THE GROWTH‐ENHANCING BUBBLE

We investigate the growth and welfare effects of the bubble that arise on equities on newly created firms by R&D activities. Considering an economy where the input to the R&D sector is the final goods financed by the savings of the household sector, we show that such a bubble has a growth‐enhancing effect under the condition opposite to the previous literature. We also explore the characteristics of the steady state equilibrium with the bubble and demonstrate that there can be dual bubbly equilibria, one of which is unstable and the other stable, and that the growth and welfare effects of an unexpected permanent change in the initial bubble are very different depending on which equilibrium the economy stays in.     

Public external debt,informality and production efficiency in developing countries

This paper proposes an alternative approach to investigate the non-linear effect of external debt on growth. In the theoretical part, we develop an endogenous growth model with formal and informal sectors to analyse the effect of the public external debt on the production efficiency. We show that an increase of the public external debt share increases the production efficiency through a positive externality effect. However, it generates an opposite effect via the reduction of the formal sector’s size in favour of a less efficient informal sector. The resultant effect becomes negative beyond an optimal level. Besides, we show that a large stock of public external debt reduces the production efficiency when it leads to a tight fiscal policy which reduces the formal sector size. Empirically, using a stochastic frontier technique with unobserved heterogeneity, for a panel of 27 developing countries for the period of 1970–2005, we confirm that the turning point associated to the effect of the share external public debt is apparent at 84%.     

On indeterminacy and growth under progressive taxation and productive government spending

We examine the theoretical interrelations between equilibrium (in)determinacy and economic growth in a one‐sector representative‐agent model of endogenous growth with progressive taxation of income and productive flow of public spending. We analytically show that, if the demand‐side effect of government purchases is weaker, the economy exhibits an indeterminate balanced‐growth equilibrium and belief‐driven growth fluctuations when the tax schedule is sufficiently progressive or regressive. If the supply‐side effect of public expenditures is weaker, indeterminacy and sunspots arise under progressive income taxation. In sharp contrast to traditional Keynesian‐type stabilization policies, our analysis finds that raising the tax progressivity may destabilize an endogenously growing economy with fluctuations driven by agents’ self‐fulfilling expectations.     

AVAILABILITY OF HIGHER EDUCATION AND LONG‐TERM ECONOMIC GROWTH*

In the present paper, we examine the economic growth effects of a limited availability of higher education in a simple endogenous growth model with overlapping generations. It is shown that this limited availability might promote economic growth by increasing aggregate savings. If the supply of human capital is restricted, its price remains high and a large share of aggregate output is distributed to young households, which need to save for their old age. When this growth‐enhancing effect is strong enough, an excessive increase in availability leads to a shortage of investable funds, which substantially reduces economic growth.     

GROWTH,INTER‐INDUSTRY AND INTRA‐INDUSTRY COMPETITION AND WELFARE*

In this paper we introduce strategic interaction between firms in an R&D growth model which captures both the intra‐industry competition between firms operating within an industry and the inter‐industry competition between firms in different industries. We show that the more substitutable the goods produced within each industry (across industries) are, that is, the more intense the intra‐industry (inter‐industry) competition, the higher is the growth rate. In the comparison between social optimum and a decentralized economy, it is shown that the market outcome is characterized by inefficiently high entry of firms within each industry and insufficient productivity growth.     

FINANCIAL LIBERALIZATION AND ECONOMIC GROWTH: A THEORETICAL ANALYSIS OF THE TRANSFORMING CHINESE ECONOMY

Abstract. We conduct a theoretical investigation into how financial reforms are affecting the long‐run economic performance of the partially reformed Chinese economy. In a model with a dual structure in commodity production and financial repression, allowing the co‐existence of a state banking system and an informal credit market and introducing heterogeneity in the transaction technologies of individuals, we examine the interactions between the state banking system and the informal credit market, and the effects of various measures of financial liberalization on individuals’ optimal portfolio choices and the macroeconomic aggregates.     

Social status, human capital formation and super-neutrality in a two-sector monetary economy

In this paper, we study how social status affects the impact of monetary policy on the long-run growth rate in a two-sector monetary economy with human capital accumulation, and find that the super-neutrality of money, with regard to the growth rate of the economy depends on the formation of human capital. In an economy with Lucas-type human capital formation, money is super-neutral; however, for an economy in which both physical and human capital are used as inputs for human capital accumulation, the money growth rate will have a positive effect on the long-run economic growth rate. The existence, uniqueness and saddle-path stability of balanced-growth equilibrium are also examined.     

Quality dualism

We suggest a theory of quality dualism, defined in terms of the gap between the highest quality good produced in the informal sector and the lowest quality produced in the formal sector. We develop a model of vertically differentiated products, in which firms producing in the formal and informal sectors face different factor prices, and have a relative advantage in the manufacture of different qualities. We then use the model to examine the cyclical behavior of the respective sizes of the two sectors. Finally, we point out that factor price changes, which reduce or increase the size of the informal sector, may have the same or opposite effect on the degree of dualism in the economy.     

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.     

ESTIMATES OF INTANGIBLE INVESTMENT BY INDUSTRY AND PRODUCTIVITY GROWTH IN JAPAN

In estimating intangible investment in Japan at the industry level, we find a high intangible investment/gross value added ratio in the information technology (IT) sector and negative growth rates in intangible capital in 13 industries over the decade from 2000. When we examine the impacts of intangible investment on total factor productivity growth, we find a significant and positive effect on total factor productivity growth in the market economy. In a revised estimation that considers intertemporal knowledge spillovers, the estimated rate of return on intangibles in the IT sector is quite high after the IT revolution. The results imply that intangible assets have been underinvested in the IT sector.     

GROWTH, R&D AND WELFARE: THE ROLE OF PUBLIC POLICY

This paper analyzes the normative side of an R&D growth model in which market structure and growth are jointly determined in the equilibrium of a one‐sector economy under monopolistic competition. We find that a distortion in the allocation of R&D, namely the presence of technological spillovers between firms, generates two market failures: insufficient growth and excessive entry of firms. We show that this result is driven by the interplay between market structure and growth. A simple tax/subsidy scheme to support the efficient solution is proposed.     

Intangible Investment and Changing Sources of Growth in Korea

We examine how intangible investments change the sources of growth in the Korean economy. After constructing a novel industry‐level data set on intangibles, we estimate the contribution of intangible‐intensive industries and other industries to aggregate productivity growth in 1981–2008. The contribution of intangible‐intensive industries to aggregate labour productivity growth has significantly increased, whereas that of other industries has substantially decreased. The increased contribution of intangible‐intensive industries is mainly associated with total factor productivity growth rather than with input growth. This suggests that innovations related to intangible investments in these industries might become a new key source of productivity growth in Korea.     

GROWTH IN THE SHADOWS: EFFECT OF THE SHADOW ECONOMY ON U.S. ECONOMIC GROWTH OVER MORE THAN A CENTURY

Taking a long‐term look at U.S. economic growth over 1870–2014, this paper focuses on the spillovers from the shadow or the unofficial economy to growth in the official sector. Shadow activities might spur or retard economic growth depending on their interactions with the formal sector and impacts on the provision of public goods. Nesting the analysis in a standard neoclassical growth model, we use a relatively new time series technique to estimate the short‐run dynamics and long‐run relationship between economic growth and its determinants. Results suggest that prior to World War II (WWII) the shadow economy had a negative effect on economic growth; however, post‐WWII the shadow economy was beneficial for growth. The sanding effect of the shadow economy in the earlier period is especially robust to alternate considerations of possible endogeneity and an alternate set of growth determinants.

PROTECTION,INVOLUNTARY SELF‐EMPLOYMENT AND WELFARE

A small open economy operates with a unionized import‐competing sector and an informal “self‐employed” sector. Productivity varies across people in the informal sector. The full‐employment structure accommodates “underemployment or involuntary self‐employment” in the flexible‐wage informal sector. Protection increases the cost of capital and may increase the set of people who are involuntarily employed in the informal sector. Even if one ignores the consumption distortion effect of a tariff, the tariff may fail to be second‐best because it may raise underemployment. Our results on tariff‐reform are consistent with some recent empirical evidence.     

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.     

Reform,informal sector,and extortion

Informal economy involving unrecorded, unregistered, extra‐legal activities employs majority of the work force in the developing world. Such extra‐legal existence of informal production is facilitated through extortion by agents of political forces in power. Also, extortion activities themselves constitute an informal segment. Full‐scale general equilibrium consequences of such institutions are rarely discussed in the literature. We develop a well‐specified general equilibrium model to explore the possible consequences of reform. Economic reform may have an expansionary effect on the number of extortionists. Depending on capital mobility and factor intensity assumptions informal output and informal wage may increase.     

SIZE OF THE PUBLIC SECTOR,ECONOMIC GROWTH AND THE INFORMAL ECONOMY: DEVELOPMENT TRENDS IN THE FEDERAL REPUBLIC OF GERMANY*

The growth of the public sector in the post-war period and the consequences of this development for economic growth is a strongly disputed subject of economic theory and policy. In this paper the development trends of state activities in the case of the Federal Republic of Germany are presented. The structure of public expenditures as well as the tax structure are taken into consideration and possible impacts on real economic growth are analysed. The negative correlations between some kinds of public expenditures (or taxes) and the growth rate of real GNP should not be taken in proof of the growth-retarding effects which might ensue from increasing state activities. It seems to be more likely that state activities have induced shifts of resources from the formal into the informal economy. Politicians should be aware that some measures of economic policy conventionally proposed will strengthen the movement into the informal economy, thus intensifying the current problems within the public budgets as well as in the social security system.     

FISCAL DECENTRALIZATION AND ECONOMIC GROWTH OF VIETNAMESE PROVINCES: THE ROLE OF LOCAL PUBLIC GOVERNANCE

This study offers an insight into the public governance role in the relationship between fiscal decentralization and provincial economic growth in Vietnam. Fiscal decentralization measures are assorted. Applying a sequential (two‐stage) estimation for the panel data of 62 provinces of Vietnam over the 2006–2015 period, we find that first, fiscal decentralization is positively related to the economic growth of Vietnamese provinces. Second, the effects of public governance on economic growth vary across provinces depending on various levels of local public governance. Interestingly, the effect of fiscal decentralization is strengthened when this variable is added along with better quality of public governance. In a region of high public governance quality, fiscal decentralization exerts a positive effect on its economic growth. Our findings imply that the design of fiscal decentralization needs to be associated with local governments’ ability of public governance to improve the local economic growth.
