Happiness,income and poverty

There is considerable evidence from a variety of sources to suggest that well-being is a function of relative income. These findings have been used to explain the Easterlin Paradox, whereby a rise in income for all does not lead to a rise in average happiness in a country (even though the cross section relationship between income and happiness is positive). This relativity of utility has led to calls for policy to focus away from GDP. I here first discuss some of the evidence that well-being is indeed relative in income, but then consider two relatively little-analysed issues to suggest that there may continue to be a role for GDP per capita in happiness-based policy: the inequality of subjective well-being, and the specific case of those in income poverty.     

Disentangling the Poverty Effects of Sectoral Output,Prices, and Policies in India

This paper attempts to disentangle the poverty effects of key policy variables that directly affect the poor (namely the government‐led channel of development spending and financing) in both agricultural and non‐agricultural sectors after accounting for the effect of respective sectoral per capita income and prices, using data from India over five decades. The paper emphasizes the sectoral composition of income and prices as mechanisms influencing the level of poverty and establishes empirically that it is the rise in non‐agricultural per capita income that reduces rural poverty via the channel of internal migration, after having controlled for the variation in key components of fiscal spending and monetary/financial policy via the availability of credit. Uneven sectoral growth pattern explains why urban poverty becomes a spill‐over of persistent rural poverty when the agricultural sector shrinks. While checking for robustness, there is evidence that the rise in non‐agricultural income alone may not reduce rural poverty, when measured in terms of rural infant mortality rate as a non‐income indicator of well‐being.     

A segmented trend model to assess fiscal sustainability: The US experience 1929–2009

The academic literature has focused largely on testing for long-run fiscal sustainability. In this exercise we formulate a flexible regression model that can be used to assess the sustainability of a more recent build-up of fiscal deficits and debt that would be of major concern to policy makers. The analysis of US data shows that, after adjusting for some fundamentals, the gross Federal debt–income ratio has been growing at an unsustainable rate of 4 % per year since 2007. The net debt–income ratio does not show such a significant trend. Since not all government assets are readily available to reduce debt, significant positive trends in the gross debt–income ratio calls for policy actions.     

Wealth,Natural Capital,and Sustainable Development: Contrasting Examples from Botswana and Namibia

Theoretical work has demonstrated that sustainable development requires non-declining per capita wealth, where wealth is defined to include produced, natural, human and social capital. Several studies have attempted to measure total national wealth or changes in wealth, but have been seriously hampered by a lack of data, especially for natural and human capital. To address this problem, the UN and other international statistical agencies developed a standardized framework for environmental accounts, the System of integrated Environmental and Economic Accounts (SEEA). Using the newly available asset accounts for natural capital, national wealth accounts are constructed and used to assess the contrasting development paths of Botswana and Namibia. Botswana, with an explicit policy of reinvestment of resource rents, has roughly tripled per capita wealth and national income over the past two decades. Namibia, with no explicit policy to use natural capita to build wealth, has seen per capita wealth and income decline.     

The Persistence of Income Shocks: Evidence from Rural Indonesia

This paper estimates the persistence of transient income shocks to farm households in rural Indonesia. Persistence is defined as the elasticity of a household's 1997 household per capita income with respect to its 1993 per capita income, controlling for time‐invariant characteristics of the household. Local rainfall levels are used as an exogenous source of transitory variation in 1993 income. Four main conclusions emerge. First, roughly 30% of household income shocks remain after four years. Second, the persistence of negative and positive shocks is approximately equal; if anything, positive shocks last longer. Third, neither positive nor negative income shocks disproportionately affect poor households. Finally, measurement error in income and unobserved household heterogeneity are important sources of bias. These findings cast doubt on common arguments advocating public intervention to stabilize or redistribute income, and suggest that anti‐poverty policy should address more permanent causes of household poverty.

The Redistributive Effects of a Minimum Wage Increase in New Zealand: A Microsimulation Analysis

This paper examines the potential effects on inequality and poverty of a minimum wage increase, based on a microsimulation model that captures the details of household composition and the income tax and welfare benefit system and allows for labour supply responses. Results suggest that, largely due to the composition of household incomes, a policy of increasing the minimum wage has a relatively small effect on the inequality of income per adult equivalent person, and a money metric utility measure, using several inequality indices. Hence, the minimum wage policy does not appear to be particularly well targeted, largely due to many low wage earners being secondary earners in higher income households, while many low income households have no wage earners at all. These results are reinforced when allowing for wage spillovers further up the wage distribution. Nevertheless, a minimum wage increase can have a more substantial effect on some poverty measures for sole parents in employment.     

The Henderson Question? The Melbourne Institute and 50 Years of Welfare Policy

I discuss selected research contributions of the Melbourne Institute of Applied Economic and Social Research to 50 years of welfare policy for those of workforce age and focus particularly on the policy focus of R. F. Henderson, the inaugural director. Following the spirit of his 1960s poverty research, in the mid‐1970s, government doubled unemployment allowances in real terms and increased pensions by approximately 40 per cent. Both income support payments were to be indexed by average wage increases. At the time, unemployment was typically around 1 per cent and the pension take‐up for those of workforce age was also limited. Today, income support take‐up rates have probably increased fivefold. In response, government has adopted a ‘make work pay’ policy over the last two decades and indexed allowances for Consumer Price Index increases and allowances have fallen by 25–35 per cent, relative to community living standards. Pensions continue to be indexed by average wage changes. I address a range of questions arising from this experience, including: Why has government abandoned the Henderson recommendations?; Is there any evidence that a ‘make work pay’ policy is working?

     

Is India Shining?

The popular perception about economic reforms having benefitted only the richer districts of India between 1999/2000 and 2004/2005 is investigated. Using the spatial dynamics of district‐level per‐capita income it was found that income distribution did not change between the years examined. It is argued that this is because of per‐capita income across districts being spatially positively correlated. Physical infrastructure, human capital, and factories are identified as factors responsible for increase in income for both the rich as well as the poor districts. Infrastructure, physical or social, is a key component of growth in India. A policy impact analysis shows development of better drainage and potable water systems has a large impact on income. For the year 2001/02, it was found that for every 1% increase in closed drainage system and potable water, district‐level median income increases by 1.39% and 0.21%, respectively.     

A structural economic dynamics approach to balance-of-payments-constrained growth

This paper derives a balance-of-payments equilibrium growthrate analogous to Thirlwall's Law from a Pasinettian multi-sectormacrodynamic framework. The resulting formula, which we callthe Multi-Sectoral Thirlwall's Law, asserts that a country'sgrowth rate of per capita income is directly proportional tothe growth rate of its exports, with such a proportionalitybeing inversely (directly) related to sectoral income elasticitiesof demand for imports (exports). These income elasticities areweighted by coefficients that measure the share of each sectorin total imports and exports, respectively. It is shown thatseveral theoretical, empirical and policy implications can bedrawn from such a structural economic dynamics approach to balance-of-payments-constrainedgrowth.     

Converting Forests to Farms: The Economic Benefits of Clearing Forests in Agricultural Settlements in the Amazon

Agricultural expansion into tropical forests is believed to bring local economic benefits at the expense of global environmental costs. The resulting tension is reflected in Brazilian government policy. The national agrarian reform program has settled farm families in the Amazon region since the 1970s, with the expectation that they will clear forests in order to farm the land. On the other hand, recent Brazilian policy initiatives seek to reduce deforestation to mitigate climate change. We contribute to the policy debate that surrounds these dual goals for the Amazon by estimating the marginal effects of new agricultural land on the full income and assets of farm settlers over a 13-year period from 1996 to 2009. Using micro panel data from agrarian settlements where forest was being rapidly cleared, and controlling for factors that would otherwise confound the relationship, we estimate the effect of converting forest to agriculture on total household income to estimate the opportunity cost of conserving forest. Our measure of income reflects any re-allocation of resources by utility maximizing households and any productivity effects due to loss of forest ecosystem services. The estimated effect of new agricultural land on income is positive, but small relative to the income per hectare of previously cleared land. However, we show that income increases investment in physical assets, which raises households’ income generating capacity and future accumulation of assets. Thus, while there is only a small immediate income gain from clearing more forest, the long-term effects on wealth are still substantial. This demonstrates that given the right conditions, conversion of forest to agricultural land can be an impetus for asset accumulation by smallholders. It also highlights the importance of considering the indirect and long-term welfare benefits of new agricultural land when assessing the opportunity costs of forest conservation.     

The driving forces of the level and the growth rate of real per capita income in Indonesia

We investigate the driving forces behind the level and the growth rate in real per capita Gross Domestic Product (GDP) in Indonesia. The ultimate reasons and the proximate causes underlying Indonesia's economic growth since the mid-1960s are still unclear. In the literature there have been at least three ways of investigating the driving forces of economic growth in Indonesia, namely: growth accounting system, regression and causality. The difference and improvement in this article is that we employed a two-step bounds testing approach to cointegration, which has not been done before; it uses the endogenous growth model to consider 12 policy variables and two external factors that potentially affect per capita income, this number is more than that has been done before. The empirical results that we obtained using this two-step bounds testing approach help us draw policy implications that if or when implemented would be expected to increase the growth of real per capita income, as well as the welfare of the people of Indonesia. Economic growth in Indonesia is largely driven by government policy, so the ability to increase Indonesia's economic growth rate, in the long run, will largely depend on the implementation of appropriate government policies.     

Trade,aid and migrations: some basic policy issues

The link between trade policy and international migration is explored using data from the United States and Europe. "We conclude that restrictive trade policies in industrialised countries have most likely added to migration pressures. We then turn to the broader question of the effects of income growth in the sending countries on the propensity to migrate. We argue that, in relatively poor countries, an increase in income will be associated with higher migration flows. For middle income countries, however, income growth will lead to lower migrations. In the medium run, therefore, the relationship between development levels, as measured by GDP per capita, and the propensity to migrate follows an inverse-U pattern. Econometric analysis of aggregate migration flows from Southern Europe provides considerable support for such conjecture."

Evaluation of Policy Options to Encourage Welfare to Work

This article compares five alternative policy options with the January 2006 tax and social security system. Each option is designed to cost a similar amount of approximately $5 billion per year to the government at the observed level of labour supply. The five options include reducing the lowest income tax rate, increasing the tax‐free threshold, increasing the low income tax offset, decreasing all taper rates on own and partner's incomes for a number of allowances, and introducing an earned income tax credit. The criteria for comparison are the labour supply responses, the expected budgetary cost to the government after taking into account labour supply responses, the number of winners and losers from the policy change, the effects on the distribution of effective marginal tax rates, and the effects on the number of jobless households. From the results, it is clear that the option to reduce taper rates is dominated by the other options on all criteria. The other four options each have their advantages and disadvantages; no option scores best on all criteria.     

The distributive effect of monetary policy: The top one percent makes the difference

The paper evaluates the distributional effect of monetary policy. The empirical analysis is implemented for the USA, where the dynamics in income inequality is mainly driven by the variation in the top one percent of the income distribution. The paper uses the inequality measures that represent the whole income distribution. The distributive effect of monetary policy is evaluated in the cases of different frequency data. To identify a monetary policy shock, the paper applies the contemporaneous and the long run identification methods. In particular, a cointegration relation is determined among the considered variables and the vector error correction methodology is used for the identification. The obtained results indicate that contractionary monetary policy decreases income inequality. These results can have important implications for the design of policies to reduce income inequality by giving more weight to monetary policy.     

Managerial capital,occupational choice and inequality in a global economy

This study proposes a simple theory of trade with endogenous firm productivity, occupational choice and income inequality. Individuals with different managerial talent choose to become entrepreneurs or workers. Entrepreneurs enhance firm productivity by investing in managerial capital. The model generates three income classes: low‐income workers facing the prospect of unemployment, middle‐income entrepreneurs managing domestic firms and high‐income entrepreneurs managing global firms. Trade liberalization policies raise unemployment and improve welfare. A reduction in per‐unit trade costs raises top incomes and generates labour‐market polarization. A reduction in fixed exporting costs has an ambiguous effect on top incomes and personal income distribution. Policies reducing labour‐market frictions or the costs of managerial‐capital acquisition create more jobs and improve welfare. The income distributional effects of labour‐market policies depend on which policy is implemented.     

我国居民收入不平等的主要原因：市场还是政府政策？

市场因素和政府收入再分配政策是决定一国居民收入不平等程度的两个重要因素。本文采用中国家庭收入调查（China Household Income Project ,CHIP）住户数据,计算出我国居民市场收入基尼系数与可支配收入基尼系数,并同发达国家进行比较,借此探讨目前我国居民收入不平等是由市场力量造成的,还是政府收入再分配政策力度不足的结果。研究发现,从市场收入基尼系数来看,我国与发达国家之间的差距并不大。由此认为,政府收入再分配政策效果不明显是导致我国居民收入分配不平等状况较发达国家严重的主要原因。加大转移支付等再分配政策力度是缓解和改善目前我国居民收入不平等的主要途径。     

Consumption patterns in Sri Lanka: a decomposition analysis

Knowing consumer reaction to changes in prices and income is important in formulating microeconomic policies, such as public utility prices and commodity taxation. This paper analyses the consumption patterns of consumer goods grouped into eight broad commodities in Sri Lanka during the period 1975–2016, using a system-wide framework. The analysis indicates that Sri Lankan consumers allocate more than half of their income to food and nearly four fifths of their income to food, housing, and transport combined. The estimated income and own-price elasticities reveal that food, housing, medical care, and transport are necessities; clothing, durables and recreation are luxuries; and demand for all commodities is price inelastic except for recreation. To investigate the consumption growth pattern, we decomposed the growth in consumption and change in budget shares of the eight commodities into income, relative price, and change in taste. We also simulated per capita consumption expenditure of the eight commodities under various policy scenarios and found that income growth has played a significant role in Sri Lankan consumption patterns.
