Contribution of female human capital in economic growth: an empirical analysis of Pakistan (1972–2012)

This study is to find out an impact of female human capital on economic growth of Pakistan. The study has therefore, used gender separate human capital as an explanatory variable along with other factors, labor force and physical capital. In this regard a composite human capital has been constructed by taking education and health as a proxy for human capital. The long run and short run dynamics among female human capital and economic growth are empirically tested on time series data spread from 1972–2012. Johanson’s co-integration approach has been applied for the long run and Vector Error Correction Model used for the short run relationship. The results show that the long run relationship between female human capital and economic growth is positive and significant. While the short run impact of female human capital on economic growth is positive but statistically insignificant.     

A Multi-state model of state dependence in labor supply: Intertemporal labor supply effects of a shift from joint to individual taxation

In this paper I develop an intertemporal discrete choice model of female labor supply to analyze the effects of true state dependence and its effect on labor supply behavior over time. The estimation results show that state dependence is significantly positive at the extensive margin and lower but in general still significant at the intensive margin. I apply this model to study the short and long run labor supply effects of a fundamental reform of the German income tax system, i.e. the shift from joint to individual taxation of married couples and show that labor supply responses are significantly higher in the long run than in the short run.     

EFFECTS OF LABOR REALLOCATION ON PRODUCTIVITY AND INEQUALITY—INSIGHTS FROM STUDIES ON TRANSITION

From a theoretical perspective, the link between the speed and scope of rapid labor reallocation and productivity growth or income inequality is ambiguous. Do reallocations with more flows tend to produce higher productivity growth? Does such a link appear at the expense of higher income inequality? We explore the rich evidence from earlier studies on worker flows in the period of massive and rapid labor reallocation, that is, the economic transition from a centrally planned to a market-oriented economy in CEE. We have collected over 450 estimates of job flows from the literature and used these inputs to estimate the short-run and long-run relationship between labor market flows, labor productivity, and income inequality. We apply the tools typical for a meta-analysis to verify the empirical regularities between labor flows and productivity growth as well as income inequality. Our findings suggest only weak and short-term links with productivity, driven predominantly by business cycles. However, data reveal a strong pattern for income inequality in the short run—more churning during reallocation is associated with a level effect toward increased Gini indices.     

Long-run growth and welfare effects of public policies with distortionary taxation

In a one-sector growth model with infrastructure investment, we study the impact of fiscal policies on growth. The government collects taxes on labor income and profits. The government uses these revenues to purchase infrastructure investment, provide utility enhancing government services, and to provide transfer payments to the households. We show that the balanced growth rate is an increasing function of the percent of government revenues that goes to infrastructure. We find that the growth maximizing mix of taxes depends on the elasticity of substitution between inputs. In particular, with distortionary taxes, the growth maximizing tax rate on capital is higher the lower the elasticity of substitution between private physical capital and public capital. In addition, the growth maximizing size of the government is higher when the elasticity of substitution between public and private inputs is low. We also investigate welfare effects of other public expenditures as well. Depending on the elasticity of substitution in production, the welfare implications of different public policies can be substantial.     

Property Tax Circuit-breakers: Good Causes but Bad Economics

A bstract . Since 1965, 30 states and the District of Columbia have enacted programs designed to reduce the effective rate of property taxation for some low income households and for the elderly. Most often this relief is provided by so-called "circuit-breakers." It is contended that the economic arguments favoring circuit-breakers are empirically unproven and theoretically suspect. The tax may be progressive , not regressive , and the device may transfer income from low to high income households. Any short run redistribution of income to favor the poor or the elderly would, in the long run, merely shift the timing of their tax payments. Circuit-breakers encourage over-consumption of housing and misallocation of housing resources. Reducing the tax base, they produce higher rates and so increase the tax burden.     

Land conservation,growth and welfare

This paper identifies the factors, such as leaving land fallow and conservation inputs, for conserving and enhancing soil fertility of land. The growth and welfare effects of these land policies are then examined. Leaving land fallow and conservation inputs raise the equilibrium soil fertility. In the short run, the polices can render unfavorable impacts to the economy, such as decreases in the land supply by the fallow plan, or reductions in public services and falls in private capital formation. Nonetheless, both policies have ambiguous impacts on growth and welfare of the economy in the long run. Furthermore, due to the favorable impact on initial consumption, the welfare-maximizing tax rate or transfer ratio is larger than the one for growth maximization. However, for the land fallow ratio, both rates are the same.     

Jealousy and underconsumption in a one-sector model with wealth preference

The present paper examines the effects of consumption externalities on economic performance in a one-sector model with wealth preference. The presence of the wealth preference generates a wealth effect in consumption growth, which plays a crucial role for consumption externalities to have impacts on the economy. Our main findings are: (i) regardless of the assumption of inelastic labor supply, the distortionary effect of consumption externalities stays in the long run; (ii) the income tax as well as the consumption tax can modify the efficiency; and (iii) the numerical simulations supplement theoretical findings.     

WILL THE “TRUE” LABOR SHARE STAND UP? AN APPLIED SURVEY ON LABOR SHARE MEASURES

Labor's share of income is a key variable in economics. It plays a leading role in analysis of (in)equality, globalization, technical change, growth theories, etc. Notwithstanding this broad application, there are many different definitions of the labor share. Understanding and synthesizing those differences is the purpose of this applied survey. Empirical measures may vary reflecting the allocation of income components that cannot be directly ascribed to capital or labor. We examine the alternative assumptions made in the literature in this regard and quantify and motivate the resulting discrepancies. Focusing (mostly) on US data, we show that different measures can have very distinct properties in terms of the observed stochastic trends, shares of short‐, medium‐, and long‐run variation and volatilities, persistence and mean‐reversion properties, and susceptibility to structural breaks. For instance, while “short‐run” properties of the surveyed labor share measures are relatively consistent across all definitions (and countercyclical), their “medium‐” and “long‐run” trends may diverge substantially (and are procyclical). To substantiate our analysis, we document the implications of discrepancies in the empirical labor share definition for growth accounting, analyzing the effect of technology shocks, and for estimating inflation dynamics.     

Fiscal Policy and Economic Growth

This paper surveys the literature on fiscal policy and economic growth. We present a unifying framework for the analysis of long run growth implications of government expenditures and revenues. We find that several tax rates and expenditure categories exhibit a direct impact on the growth rate of the economy. In a creative synthesis we have assigned the relevant literature to the twelve introduced policy variables. Due to the equivalence of some policy variables we are left with six degrees of freedom, where we need four to internalize the model's intrinsic externalities, leaving two instruments to conduct short run fiscal policy.     

AN EMPIRICAL GROWTH MODEL FOR MAJOR OIL EXPORTERS

This paper develops a long‐run output relation for a major oil‐exporting economy where the oil income‐to‐output ratio remains sufficiently high over a prolonged period. It extends the stochastic growth model developed in Binder and Pesaran (1999) by including oil exports as an additional factor in the capital accumulation process. The paper distinguishes between the two cases where the growth of oil income, g^o, is less than the natural growth rate (the sum of the population growth, n, and the growth of technical progress, g), and when g^o ≥ g + n. Under the former, the effects of oil income on the economy's steady growth rate will vanish eventually, while under the latter oil income enters the long‐run output equation with a coefficient which is equal to the share of capital if it is further assumed that the underlying production technology can be represented by a Cobb–Douglas production function. The long‐run theory is tested using quarterly data on nine major oil economies. Overall, the test results support the long‐run theory, with the existence of long‐run relations between real output, foreign output and real oil income established for six of the nine economies considered.

房地产税改革与土地财政困局破解——基于对地方财政影响的情景分析

地方政府过度依赖土地出让收入是当前中国公共管理面临的重要难题。改革房地产税制并触发土地制度的连锁反应是破解中国土地治理困局的基本出路。通过预测不同改革方案下典型城市住房相关土地财政收入变化,评估房地产税替代土地出让（纯）收益成为地方支柱性收入源的前景。研究发现,如果合理设计覆盖城市存量和新增住房的房地产税,可在短期内保证地方土地财政收入的相对稳定,并在远期实现房地产税替代土地出让金成为地方财政支柱的目标,增强土地财政收入的可持续性。近期政府应改变“重流转、轻保有”的状况,将房地产税培育成为地方主体税种,远期应推进城乡一体化土地市场体系、土地出让制度和土地增值税制度联动改革,使地方土地财政收入从以一次性的土地出让纯收益为主向以持续的房产保有税、土地增值税等为主转变,促进政府土地管理本位职能回归,破解土地财政与政府治理困局。     

人均收入差距导向的投资战略

除了税收手段直接调整人均收入差距之外,政府可利用投资配置来影响生产过程,进而调整人均收入差距。在总量封闭经济的框架下,本文以人均收入差距最小化为目标,通过引入多地区多产业Cobb-Douglas生产函数、劳动一资本比率、资本时变率,改造最优经济增长模型。实验表明,通过权衡不同地区、不同产业的重要程度,调整投资在不同地区、不同产业之间的配置比率,政府可缩小人均收入差距。     

我国个人所得税改革的误区及其突破

我国个人所得税改革存在一定的误区:税制改革的重点在于流转税、当前个税属于综合与分类相结合的税收模式、劳动所得作为个税的改革核心等。反思改革误区,我国个人所得税改革应实现三点突破:一是个税改革重点应由劳动所得转向资本所得,以股息和红利所得作为资本所得课税的改革核心,取消根据持有时间长短而差别计税的优惠政策;二是不断扩大个人所得综合征税的范围,逐步实现对资本所得的综合课税、以半二元模式作为我国综合与分类相结合的个税改革模式;三是缓步实现对个人所得税的"增税"调整,促进我国税制结构向"双主体"模式合理过渡。     

Climate Change Policies and Tax Recycling Schemes: Simulations with a Dynamic General Equilibrium Model of the Italian Economy

A dynamic general equilibrium model of the Italian economy is used to assess the impact of carbon taxation (or auctioned carbon permits), where additional revenue is used to cut either existing taxes on labor or on capital income. Simulation results do not support the existence of the so-called "double dividend" when labor taxes are reduced, whereas lower tax rates on capital have mild positive effects on growth and welfare, with progressivity properties on income distribution. These findings hinge on the assumptions of open economy, given world interest rate, and capital mobility.     

Flat tax reform: A quantitative exploration

This paper explores quantitatively the general equilibrium implications of a revenue neutral tax reform in which the current income and capital income tax structure in the U.S. is replaced by a flat tax, as proposed by Hall and Rabushka (1995), (The Flat Tax, 2nd ed. Hoover). The central aspects of such reform, the impact of tax reform on capital accumulation and labor supply, as well as its distributional consequences, are analyzed in a dynamic general equilibrium model. Main results are that, (i) the elimination of the actual taxation of capital income has an important and positive effect on capital accumulation; (ii) mean labor hours are relatively constant across tax systems, but aggregate labor in efficiency units increases; (iii) in all circumstances analyzed, the distributions of earnings, income and especially wealth become more concentrated.     

Introducing the supply side into the LBS Model

This Briefing Paper describes a new version of the London Business School model, which incorporates our most recent research on the supply side. The changes reflect the desire to improve the specification of the supply-side of the model, and to capture the effects of taxes on the incentives to save, invest and to work, while still retaining the basic features of the income-expenditure framework. The main features of the new model are: - Gross domestic product is determined as the sum of the outputs of five sectors. Previously GDP was determined by the demand side as the sum of the expenditure components. - Domestic demand for the output of the private sector depends on domestic absorption and on the price of this output relative to import prices. Overseas demand for exports depends on world economic activity and on the price of exports relative to the world price of exports. - Supply depends on the capital stock, real unit labour costs and real raw material prices. In the short run, input prices are allowed to affect the mix between goods which are exported and those which are supplied to the domestic market. In the long run, however, the mix depends only on the price of exports relative to the price of domestically supplied goods (i.e., relative profitability). - In the short run, disequilibrium in the goods market is reflected in adjustments to prices, inventories and the external balance. - Since gross domestic product is determined by summing the output of each sector, output decisions are reconciled with expenditure decisions by making imports the difference between final expenditure and aggregate supply. - In the long run, increases in government expenditure crowd out private expenditure, but the effect takes several years to come through. - A cut in corporation taxes which is not financed by higher taxes elsewhere boosts the supply side by raising investment and the capital stock, but not by enough to raise revenues sufficiently to pay for the tax cut. Private sector saving increases but not by enough to fund higher public sector borrowing, so the current account goes into deficit. - In the short run, both supply and demand factors influence economic activity; in the long run, the path of the economy depends only on population growth, capital accumulation and technical progress.     

Federalism,taxation, and economic growth

We present a model of endogenous growth where government provides a productive public good financed by income and capital taxes. In equilibrium, a decentralized government chooses tax policy to maximize economic growth, while a centralized government does not do so. Furthermore, these conclusions hold regardless of whether governments are beholden to a median voter or are rent-maximizing Leviathans. However, a decentralized government will under-provide public goods which benefit citizens directly, while a central government beholden to the median voter will optimally invest in such public goods.     

The winners and losers of tax reform: An assessment under financial integration

I quantify the macroeconomic and redistributive effects of the unilateral elimination of the capital income tax in a two-country, heterogeneous-agent incomplete markets model with progressive labor income taxes. Home, by implementing the reform, induces government responses where labor income is taxed in Home and mostly subsidized in Foreign. In addition, post-reform price dynamics reduce Home’s wealth and suppress households’ ability to do consumption smoothing, with negative effects on the majority—particularly on the poor. In turn, Foreign accumulates wealth, and price movements work particularly in favor of the poor. As a result, a large majority in Home prefers the status quo whereas Foreign supports the reform unanimously. These findings are robust to alternative scenarios where (i) the borrowing constraints are relaxed, (ii) both countries jointly eliminate capital income taxes, (iii) foreign interest income is taxed, and (iv) Home capital income tax is reduced from 40% to 35%.     

A cointegration approach to modeling human capital formation,self-employment,and economic growth: evidence from Pakistan

This study aims to empirically investigate the dynamics of relationship among human capital formation, self-employment (SE), and economic growth in Pakistan. Using quarterly data of primary school enrollment, SE, and GDP per capita, we employed ARDL bound testing approach to cointegration covering the time span of 1995–2010. We found that in the long run, primary school enrollment, high school enrollment and SE have significant impact on economic growth. Enrollment in primary schools (EP) has a strong positive and significant impact on economic growth, whereas enrollment in high school has a relatively small positive and significant impact on economic growth in the long run in Pakistan. Further, SE has a small, positive and significant impact on economic growth in the long run. In short run, enrollments in high schools and SE have weak positive impact on economic growth whereas, EP has a strong positive and significant impact on economic growth in Pakistan. Further it is found that that there is unidirectional long run causality from self employment to economic growth followed by the bidirectional short run causality between economic growth and high school enrollment, GDP per capita and primary school enrollment, high school enrollment and primary school enrollment.
