Economic liberalization and wage inequality in the presence of labour market imperfection

This paper is purported to analyze the consequences of liberalized economic policies on the skilled–unskilled wage inequality in the developing countries using a three sector general equilibrium model reasonable for at least a few developing economies. The analysis of the paper has found that the wage inequality rises unambiguously due to a reduction of import tariff from the low-skill manufacturing sector. However, an inflow of foreign capital produces a favourable effect on the wage inequality under a reasonable factor intensity condition. Interestingly, contrary to the common wisdom, a policy of labour market reform may raise the competitive unskilled wage and improve wage inequality under reasonable condition.     

Regional implications of financial market development: Industry location and income inequality

We develop a heterogeneous-firms model with trade in goods, labor mobility and credit constraints due to moral hazard. Mitigating financial frictions reduces the incentive of mobile workers to migrate to one region such that an unequal distribution of industrial activity becomes less likely. Hence, financial market development has opposite regional implications as trade liberalization. While the former leads to more dispersion of economic activity across space, the latter tends to drive clustering. This has immediate implications for income inequality both between regions and workers. According to our model, financial development reduces inequality in both dimensions.     

Endogenous capital market imperfections, human capital, and intergenerational mobility

In this paper, capital market imperfections are endogenized considering an adverse selection problem between banks and borrowers. We develop a growth model with linear OLG wealth dynamics, where agents are heterogeneous in terms of observable wealth and ability, which is private information. We show that banks react to this informational asymmetry by granting higher loans to talented borrowers. This, in turn, helps poor and talented agents to become educated and catch up with the rich agents. Furthermore, the credit market friction leads to greater human capital accumulation.     

Families and firms: Agency costs and labor market imperfections in Sialkot's surgical industry

The family firm is generally viewed as an organizational solution to agency costs in the labor market for managers and institutional underdevelopment. Consistent with this view, this paper links the preponderance of family firms in the surgical instrument industry of Sialkot to the prevailing agency and institutional problems. However, strong dependence on family management coupled with restrictions on family size constrains the firms from optimally choosing management size. The resulting labor market distortion is manifested by a significant positive correlation between the founder's family size and the firm size such that the founders who have more brothers (a larger pool of potential managers) end up with bigger firms.     

Monetary policy,endogenous transactions,and financial market segmentation

An endogenous financial market segmentation model is constructed to explore the role of costly credit as a medium of exchange in the monetary policy elasticity of financial market activity. Against inflation risk, credit is an alternative insurance device to a cash transfer from the financial market. In equilibrium, credit reduces the financial market activity rate. Monetary policy has redistributive effects across economic individuals. Inflation may not tax financial market non-participants. However, it may tax financial market participants by increasing the financial market activity rate. Welfare may increase and the optimal money growth rate can be positive.     

Credit market imperfection,lack of entrepreneurship and capital outflow from a developing economy

This paper explores the impact of credit market imperfection on lack of demand for capital, trade, and capital flows in an economy with wealth heterogeneity. In particular, we look at the implications of wealth heterogeneity. We show that the low return of capital and lower output of credit-intensive output in autarky may reflect lack of entrepreneurship and demand for credit due to wealth heterogeneity and eventually may lead to capital outflow from a capital-scarce country. This is a different way of echoing the sentiment of the well–known Lucas paradox, which suggests that capital might flow from the poor to the rich countries. We also show the possibility of trade and capital flow being complements and not substitutes, as is usual in standard trade models driven by factor abundance.     

Trade liberalisation,market competition and wage inequality in China's manufacturing sector

Economic reforms of the late 1980s have contributed to rapid economic growth in China. While the overall standard of living has improved, economic growth has also resulted in an increase in income inequality. Rising income inequality can increase social tensions that can impede further economic growth. By making use of firm level panel data, this paper focuses on the impact of increased market competition and trade liberalisation on skilled–unskilled wage inequality in China's manufacturing sector. A theoretical model is used to argue that trade liberalisation and market competition can affect skilled–unskilled wage inequality. Based on this result, an econometric model is specified. The empirical analysis presented in this paper shows that increased trade liberalisation has contributed to an increase in skilled–unskilled wage inequality in China's manufacturing sector. However, increase in market competition has the opposite effect.     

Growth,inequality, and poverty reduction in developing countries: Recent global evidence

The study presents comparative global evidence on the transformation of economic growth to poverty reduction in developing countries, with emphasis on the role of income inequality. The focus is on the period since the early-mid-1990s when growth in these countries as a group has been relatively strong, surpassing that of the advanced economies. Both regional and country-specific data are analyzed for the $1.25 and $2.50-level poverty headcount ratios using World Bank Povcalnet data. The study finds that on average income growth has been the major driving force behind both the declines and increases in poverty. The study, however, documents substantial regional and country differences that are masked by this ‘average’ dominant-growth story. While in the majority of countries, growth was the major factor behind falling or increasing poverty, inequality, nevertheless, played the crucial role in poverty behavior in a large number of countries. And, even in those countries where growth has been the main driver of poverty-reduction, further progress could have occurred under relatively favorable income distribution. For more efficient policymaking, therefore, idiosyncratic attributes of countries should be emphasized. In general, high initial levels of inequality limit the effectiveness of growth in reducing poverty while growing inequality increases poverty directly for a given level of growth. It would seem judicious, therefore, to accord special attention to reducing inequality in certain countries where income distribution is especially unfavorable. Unfortunately, the present study also points to the limited effects of growth and inequality-reducing policies in low-income countries.     

R&D investment and internal finance: the cash flow effect

This paper investigates the cash flow effect on R&D investments for firms in Denmark. Evidence is found that internal funds are important in explaining R&D investments, indicating that R&D investment decisions are affected by credit market imperfections. Cash flow sensitivities are larger both for smaller firms and for firms with low debt relative to assets. Furthermore, this effect is also present after controlling for cash flow’s potential role as a predictor of future profitability.     

A joint analysis of market indexes in credit default swap,volatility and stock markets

This paper analyses the joint dynamics of the CDS, volatility and stock markets using both VAR and Markov regime-switching VAR models with market index data. It shows that the joint behaviour of the three markets is better characterized by the Markov model with two regimes corresponding to low- and high-volatile market conditions. The relationship between changes in the market indexes under a regime is consistent with theory and persistent; the information transmission process of shocks to the markets is similar for the two regimes with a more important role for CDS shock; and the volatility in the money market is an important determinant of regime-switching. The findings have practical implications, particularly for hedging strategies with market indexes under different market conditions.     

Foreign Direct Investment, inequality, and growth

This paper examines the interactions between Foreign Direct Investment (FDI), inequality, and growth, both from an empirical and a theoretical point of view. Using a panel of 119 developing countries, we observe that FDI promotes both inequality and growth, and tends to reduce the share of agriculture to GDP in the recipient country. We then set up a growth model of a dual economy in which the traditional (agricultural) sector uses a diminishing returns technology, while FDI is the engine of growth in the modern (industrial) sector. The main predictions of the model are consistent with the stylized facts observed in the data.     

Momentum crash,credit risk and optionality effects in bear markets and crisis periods: evidence from the US stock market

This study explores whether the credit risk anomaly exhibits option-like behaviour similar to the momentum anomaly. It finds that the inverted credit risk spread indeed displays option-like behaviour in bear market states. Unlike a momentum portfolio, which is effectively a short call option on the market, an inverted credit risk portfolio appears to be a long call option on the market.     

Reliving the 1950s: the big push, poverty traps, and takeoffs in economic development

The classic narrative of economic development—poor countries are caught in poverty traps, out of which they need a Big Push involving increased investment, leading to a takeoff in per capita income—has been very influential in foreign aid debates since the 1950s. This was the original justification for foreign aid. The narrative lost credibility for a while but has made a big comeback in the new millennium. Once again it is invoked as a rationale for large foreign aid programs. This paper applies very simple tests to the various elements of the narrative. Evidence to support the narrative is scarce. Poverty traps in the sense of zero growth for low-income countries are rejected by the data in the whole period 1950–2001 and for most sub-periods. The poorest quintile also does not have significant negative growth of the relative income ratio to the world’s richest country over 1950–2001, nor is relative growth for the lowest quintile significantly different than other quintiles. The claim that “well-governed poor nations” are caught in poverty traps is rejected by simple regressions that control for both initial income and quality of government (instrumenting for the latter). The idea of the takeoff also does not garner much support in the data. Takeoffs are rare in the data, most plausibly limited to the Asian success stories. Even then, the takeoffs are not associated with aid, investment, or education spending as the standard narrative would imply.     

Income inequality,unemployment, and poverty in Nigeria: a vector autoregressive approach

The main features of poverty are low levels of consumption and income, a fact‐of‐life in most African countries. This paper analyzes the fundamental trends of per capita income, government capital expenditure, the human development index, and the rate of unemployment in the Nigeria. A vector autoregressive model finds that: A reduced unemployment rate improves human development and consequently reduces poverty. As growth in public capital expenditure rises, unemployment falls and the human development index improves. Therefore, infrastructure‐based policies, which initially reduce unemployment, will also improve the living conditions of Nigerians in the end.     

Recent decline in wage inequality and formalization of the labour market in Argentina

Labour market conditions improved during the 2000s in Latin America, a process that included a reduction in the magnitude of informal employment. A decline of wage inequality was another feature of this period. Both dynamics were particularly intense in Argentina. The purpose of this study is to evaluate the role played by the process of formalization of the labour market that occurred in Argentina during that period on the reduction of income inequality, while additionally taking into account other factors that might have also contributed to such dynamics of income inequality. The method employed is a decomposition proposed by Firpo, Fortin and Lemieux, which allows extending the Oaxaca-Blinder approach to decompose some distributive statistics of income between a ‘composition effect’ and a ‘returns effect’. The study concludes that the process of increasing labour market formalization had an equalizing effect over the period, a finding that had not been emphasized in previous studies.     

Financial market integration, labor markets, and macroeconomic policies

We used a dynamic two-country optimizing model featuring a labor–market friction to analyze the implications of financial market integration for the propagation of macroeconomic policies in an open economy. Our main result is that the labor–market friction we analyzed substantially reduces the magnitude of the effect of financial market integration on the propagation of macroeconomic policies.     

Primitive and Modern Economics: Derivatives,Liquidity, Value,Panic and Crises,A Uniformitarian View

This paper investigates aspects of economics in the context of complex society and the nature of investment devices in cross-cultural comparison, placing special attention on the new global issues of money, hedge fund contracts, derivatives and other risk-spreading concepts and practices. The function of these are compared to the behavior of the inventors and practitioners in other cultures. Similarities are noted with religious formulators and the process of conversion and the operation of the market and credit paralleled with the concept of Mana. This work provides a context for understanding contemporary human economic behavior. Novel structures of symbolic worth are associated with individual presentation and performance. Clearly concepts of value and credit have been changing in modern financial culture. Indeed, they have been expressing forms that have traditionally been associated with primitive economics. An understanding of the current financial and social losses resulting from the subprime collapse is presented along with a means to counter it.

The subversive nature of inequality: Subjective inequality perceptions and attitudes to social inequality

This paper shows that higher levels of perceived wage inequality are associated with a weaker (stronger) belief into meritocratic (non-meritocratic) principles as being important in determining individual wages. This finding is further corroborated using various complementary measures of individuals’ perception of the chances and risks associated with an unequal distribution of economic resources, such as their perception of the chances of upward mobility. I finally show that those individuals perceiving a high level of wage inequality also tend to be more supportive of redistributive policies and progressive taxation. Taken together, these findings suggest that high levels of perceived wage inequality do have the potential to undermine the legitimacy of market outcomes.     

Labor market search, sticky prices, and interest rate policies

What accounts for the significant real effects of monetary policy shocks? And what accounts for the persistent and hump shaped responses of output and inflation in response to such shocks? These questions are investigated in a model that incorporates labor market search, habit persistence, sticky prices, and policy inertia. While habit persistence and price stickiness are important for the hump shaped output response and the long, drawn out inflation response, respectively, labor market frictions increase the output response and reduce the inflation response relative to an otherwise similar model based on a Walrasian labor market. Significantly, policy inertia itself is found to be the most important factor in accounting for the magnitude of the output effects of policy shocks in the model.     

Redistribution,inequality, and efficiency with credit constraints: Implications for South Africa

We develop a model that jointly determines the distribution of income and the aggregate macrodynamics. We identify multiple channels through which alternative public policies such as transfers, consumption and income taxes, and public investment will affect the inequality-efficiency trade-off. Income tax and transfers have both a direct income and an indirect substitution effect; a consumption tax has only the latter. We present extensive numerical simulations motivated by the South African National Development Plan 2030, the objective of which is to reduce soaring inequality and increase per capita GDP. Our results illustrate how the judicious combination of social grants and a consumption tax may help achieve these targets. The simulations also suggest that the sharp decline in the private-public capital ratio, coupled with a high degree of complementarity between public and private capital may help explain the persistence of market inequality in South Africa during the last two decades.
