Migrants as second-class workers in urban China? A decomposition analysis

In urban China, urban resident annual earnings are 1.3 times larger than long-term rural migrant earnings as observed in a nationally representative sample in 2002. Using microsimulation, we decompose this difference into four sources, with particular attention to path-dependence and statistical distribution of the estimated effects: (1) different allocation to sectors that pay different wages (sectoral effect); (2) hourly wage disparities across the two populations within sectors (wage effect); (3) different working times within sectors (working time effect); and (4) different population structures (population effect). Although sector allocation is extremely contrasted, with very few migrants in the public sector and very few urban residents working as self-employed, this has no clear impact on earnings differentials, because the sectoral effect is not robust to the path followed for the decomposition. The second main finding is that the population effect is robust and significantly more important than wage or working time effects. This implies that the main source of disparity between the two populations is pre-market (education opportunities) rather than on-market.     

Investment–productivity dynamics and distribution dynamics in a multisector economy: some theory and an application to Italian regions

In this paper, we study the investment–productivity dynamics in the Framework Space, presented by Böhm and Punzo [Cycles, Growth and Structural Change, Routledge, London (2001) 47], as the distribution dynamics of the production sectors of an economy. We apply such theoretical framework to data from Italian regions to identify differences in sectoral behaviors both within and across regions. Our main findings are: sectors within a region generally follow different regime dynamics; Southern Italian regions are generally characterized by higher degrees of heterogeneity in sectoral growth behaviors and of regime instability. Also, we find support to the hypothesis of a positive relation between this type of instability and unemployment, as argued by the Neo-Austrian theory of structural dynamics.     

Sectoral determinants of foreign affiliate sales employing European data

We test theories on sectoral determinants of foreign affiliate sales employing European foreign affiliate sales statistics (FATS). On the one hand, we test hypotheses that foreign affiliate sales are less likely in sectors with complex tasks and more likely in sectors where communication with customers is important. On the other hand, we test the hypothesis that the force of gravity is stronger in more complex sectors. Employing Poisson and negative binomial estimators, we find support for the first hypotheses and contradict the second hypothesis. We show that the interaction effect between distance and complexity changes sign from negative to positive when complexity is included as a separate regressor. We propose an explanation to reconcile our findings with the basic assertion in the second hypothesis that the force of gravity is stronger in more complex sectors, based on a composition effect between horizontal and vertical affiliate sales.     

Investment, Pass-Through, and Exchange Rates: A Cross-Country Comparison

Using detailed data from the United States, Canada, the United Kingdom, and Japan, we examine the implications of exchange rates for time series of sectoral investment. Both theoretically and empirically, we show that investment responsiveness to exchange rates varies over time, positively in relation to sectoral reliance on export share and negatively with respect to the share of imported inputs in production. Important differences exist in investment endogeneity across high- and low-price-over-cost markup sectors, with investment in low-markup sectors often significantly more responsive to exchange rates. Cross-country differences in investment response are only partially explained by industrial organization arguments.     

The determinants of trade performance: influence of R&D on export flows

A theoretical model is presented, in which supply side differences between countries determine international trade flows. This model is empirically tested at a sectoral level for a group of EU countries, within a framework that focuses on changes through time and differences between countries. The results show that the validity of the theoretical model is limited at sectoral level. However, as expected, we find that the variable representing technological differences is significant and correctly signed for high-technology sectors. The evidence points to the existence of different production functions across countries and to the importance of supply side factors in determining the direction and the terms of trade.     

Firm heterogeneity in TFP,sectoral innovation and location. Evidence from Italy

Sectoral and territorial specificities affect a firm’s capabilities of being productive. While there is a wide consensus on this, a quantitative measure of these effects has been lacking. To this end, we combine a data-set of Italian firms with some meso regional and sectoral variables and apply a cross-classified model that allows for a clear distinction between firm, region-specific and sector-specific effects. After observing a marked TFP heterogeneity across firms, the paper addresses the issue of understanding how much differences in firms’ productivity depend on regional localisation and sector specificities. Results refer to 2004–2006 and have three aspects. First, they confirm that the main source of firm variety is mostly due to differences revealed at individual level. Secondly, we find that the sector is more important than location in explaining firms’ TFP. Lastly, the results show that firm TFP increases when it belongs to more innovative sectors. Similarly, companies get benefits from belonging to sectors where there is a high proportion of firms using R&D public support and a high propensity to collaborate in innovative projects.     

Productivity and convergence across U.S. States and industries

We examine the sources of aggregate labor productivity movements and convergence in the U.S. states from 1963 to 1989. Productivity levels vary widely across sectors and across states, as do sectoral output and employment shares. The main finding is the diverse performance of sectors regarding convergence. Using both cross-section and time series methods, we find convergence in labor productivity for both manufacturing and mining. However, we find that convergence does not hold for all sectors over the period. Decomposing aggregate convergence into industry productivity gains and changing sectoral shares of output, we find the manufacturing sector to be responsible for the bulk of cross-state convergence.     

How important is the intermediate input channel in explaining sectoral employment comovement over the business cycle?

This paper investigates both analytically and quantitatively the role of intersectoral linkages in explaining sectoral employment comovement over the business cycle. We use a multisector dynamic stochastic general equilibrium model calibrated to the 2-digit SIC level intermediate input-use and capital-use tables and sectoral productivity shocks. With indivisible labor implying constant marginal utility of leisure, intersectoral linkages at the disaggregated level generate strong employment comovement across sectors. With divisible labor, however, procyclical marginal utility of leisure can dominate intersectoral linkages, implying some negative comovement. It further requires some form of the difficulty in reallocating labor across sectors, so that the substitutability of labor supply across sectors is relatively low. With divisible labor, a limited substitution of labor hours across sectors is shown to generate strong employment comovement over the business cycle.

Economic transition,dualism and informality in India: Nature and patterns of household-level transitions

We examine the Indian economy during a peak period of high growth between 2005 and 2012 to analyse the nature and patterns of household-level transitions across different sectors, characterised by varying degrees of formality/informality and various production structures and labour processes. We find that even within this brief period, there has been a huge volume of household-level transitions across sectors. However, the overall economic structure, and its segmentations, has continued to be reproduced, along with a regeneration of ‘traditional’ non-capitalist informal spaces. To ascertain the nature of household-level transitions in terms of economic well-being, we employ a counterfactual analysis. We find that majority of transitions in the economy have been ‘unfavourable’ in nature, with large proportion of households undergoing sectoral transitions that are not optimal for them, given their socio-economic characteristics. Furthermore, the likelihood of ‘favourable’ versus ‘unfavourable’ sectoral transition, on average, significantly varies with household characteristics, some of which, like social caste, are structurally given and cannot be optimally chosen by households. Drawing upon this analysis, we reflect on the competing strands of literature that seek to explain the persistence of informality. Our analysis highlights the complexity of India's contemporary development trajectory, whereby the pre-existing economic structure is reproduced, paradoxically, through a continuous reshuffling and reconstitution of economic spaces, accompanied by significant volume of ‘unfavourable’ household-level sectoral transitions.     

Sectoral exports dynamics of Turkey: a panel co-integration analysis

This paper analyzes the role of unit labor costs and individual cost components in determining sectoral export dynamics and the change in the impact of these costs after the sequence of structural reforms in Turkey as of 2001. It employs a multivariate panel co-integration technique across 17 Turkish manufacturing sectors at different time periods. Results suggest that average elasticity changes not only between the time periods but also across the sectors. Cross-sectional elasticity differences are mostly attributable to the sectoral competitiveness and factor intensities.     

The Efficiency of Active Labor Market Policies: A Comparative Analysis of Tunisia and OECD Countries’

ABSTRACT

On the third anniversary of the Egyptian revolution and against the backdrop of lingering political instability and deteriorating economic conditions, we diagnose the constraints to sectoral growth in Egypt using the 2011 Egyptian revolution as a natural experiment. We combine quantile regressions to study sector outliers with a difference in difference methodology to capture sectoral behavior before and after revolution. We find that the revolution's effect has been adverse, on average, but heterogeneous across sectors. We identify and characterize sectors most and least impacted. Results reveal that Egypt's fastest growing sectors before Revolution have been the most vulnerable after Revolution. This evidence is supported by our diagnosis approach that shows that faster growing sectors are constrained by continuous increases in prices that threaten export competitiveness (as they erode the benefits accrued to nominal depreciation of currency). Such sectors also benefited from higher monetary growth and fewer constraints on credit availability that have mitigated somewhat the speed of deterioration in the aftermath of the revolution. Our results, which hold under several robustness checks, inform policy priorities as to how to revive investors’ confidence, boost competitiveness, and design priorities in industrial policy to ease structural impediments and align sectoral growth with macro priorities.     

中国城镇不同所有制企业职工收入差距的变化趋势

本文利用最新发布的CHIP-2007和CHIP-2002分析了2002年到2007年中国城镇不同所有制企业职工收入差距的变化趋势。我们发现这段时期不同所有制企业的收入差距正在减小,且这种收敛的趋势更有利于非国有企业职工,这与1995年到2002年的变化趋势形成鲜明对比。当我们分解收入差距时,发现个体的特征或能力的差别对于解释收入差距的重要性在显著提高。此外,市场分割对于不同所有制的企业仍然存在,特别对于高收入群体,但有逐步缩小的趋势。     

Regional divergence and club convergence in India

This paper examines regional divergence in income across different states in India, and estimates convergence clubs endogenously. The paper makes two useful contributions. First, the data is analyzed using a novel method due to Phillips and Sul (2007) leading to different conclusions in comparison to past studies, and secondly sectoral level data is employed which to our knowledge has not been employed in the literature before. Applying the novel approach to panel data relating to fifteen major states of India for the period 1968/69–2008/09, the results display significant divergence in per capita income across states at the aggregate and sectoral levels. There is also evidence of convergence clubs and variations in the number and composition of clubs across sectors. While three clubs are identified at the aggregate level, at the sectoral level we find three clubs in the industrial sector, two clubs are identified in both the agriculture and services sectors. The final part of the paper deals with the policy implications.     

A new approach to estimation of the R&D–innovation–productivity relationship

ABSTRACT

We apply a generalized structural equation model approach to the estimation of the relationship between R&D, innovation and productivity that focuses on the potentially crucial heterogeneity across sectors. The model accounts for selectivity and handles the endogeneity of this relationship in a recursive framework which allows for feedback effects from productivity to future R&D investment. Our approach enables the estimation of the different equations as one system, allowing the coefficients to differ across sectors, and also permits us to take cross-equation correlation of the errors into account. Employing a panel of Swedish manufacturing and service firms observed in three consecutive Community Innovation Surveys in the period 2008–2012, our full-information maximum likelihood estimates show that many key channels of influence among the model's components vary meaningfully in their statistical significance and magnitude across six different sectors based on the OECD classification on technological and knowledge intensity. These results cast doubt on earlier research which does not allow for sectoral heterogeneity.     

Technological leadership and sectorial employment growth: A spatial econometric analysis for U.S. counties

This paper studies the determinants of technological catch‐up considering spatial and sectoral aggregation of industries. We investigate how geographical and technological proximity to the technology leader impact regional employment growth. We model technological progress by means of a hierarchical process of catch‐up to the technology leader. We also incorporate measures for knowledge spillover effects to test the roles of competition, specialisation, and diversity at the industry level. Empirical results using data at the county level for different economic sectors (2‐dig NAICS) for the United States indicate that human capital plays a crucial role in promoting sectoral employment growth. The association between technological/geographical distance to the technology leader and employment growth varies across sectors.     

What broad banks do, and markets don’t: Cross-subsidization

We show that interbank markets are a poor substitute for “broad” banks that operate across regions or sectors. In the presence of regional or sectoral asset and liquidity shocks, interbank markets can distribute liquidity efficiently, but fail to respond efficiently to asset shocks. Broad banks can condition on the joint distribution of both shocks and, hence, achieve an efficient internal allocation of capital. This allocation involves the cross-subsidization of loans across regions or sectors. Compared to regional banks that are linked through well-functioning interbank markets, broad banks lead to higher levels of aggregate investment, higher output, and less fluctuations within regions. However, broad banks generate endogenously aggregate uncertainty.     

Sudden stops, financial frictions, and labor market flows: Evidence from Latin America

While the aggregate effects of sudden stops and international financial crises are well known, the disaggregated channels through which they work are not well explored yet. In this paper, using job flows from a sectoral panel dataset for four Latin American countries, we find that sudden stops are characterized as periods of lower job creation and increased job destruction. Moreover, these effects are heterogeneous across sectors: we find that when a sudden stop occurs, sectors with higher dependence on external financing experience lower job creation. In turn, sectors with higher liquidity needs experience significantly larger job destruction. This evidence is consistent with the idea that dependence on external financing affects mainly the creation margin and that exposure to liquidity conditions affects mainly the destruction margin. Overall, our results provide evidence of financial frictions being an important transmission channel of sudden stops and in the restructuring process in general.     

Competition,taxation and economic growth

The paper mainly examines the relationship between economic growth, tax policy and sectoral labor distribution in an endogenous growth model with expanding varieties. For analyzing these relationships, we consider an economy where three sectors of production are vertically integrated: final goods sector, intermediate goods sector and research sector. We show that the extent of imperfect competition in the intermediate products market affects both economic growth and the allocation of the available labor to all the sectors employing this input. The resources from capital taxation, which are used for financing research sector, have a U-shaped effect on growth and lead to a movement of the labor from research sector to final goods sector. Additionally, we show that if there exists a higher competitive structure in an economy, the probability of the positive effect of an increase in tax on growth gets higher.
