The Cambridge challenge to the Ricardian analysis of poverty

The Ricardian economists’ famous model of economic growth employed the Malthusian population doctrine, the law of diminishing returns, and the classical or iron law of wages. This analysis was based on utilitarian moral philosophy. The gloomy Stationary State conclusions of the Ricardian growth model — maldistribution of income and widespread poverty — were challenged by both economists and moral philosophers. A particularly important challenge was that offered by William Whewell (1794–1866), Professor of Moral Philosophy and the dominant figure at the University of Cambridge. Whewell is remembered today for his early contributions to mathematical economics. This article begins with a review of the Ricardian growth model. Next, Whewell’s system of moral philosophy is examined and the scientific and religious basis of Whewell’s antagonism to Ricardian economics is considered. After considering Whewell’s treatment of agricultural progress, economic classes, and rent doctrine, his own model of economic growth is analyzed. Finally, Whewell’s appraisal of the duty of government to those harmed by development is explored.     

李嘉图等价定理及其在中国的适用性分析

李嘉图等价定理认为,政府的财政收入形式的选择,不会引起人们经济行为的调整。但是,现代经济学家们并非完全同意李嘉图的见解,无论是对其必要条件的检验还是对其结论的检验都存在着争论。而通过实证分析我国1989—2004年的政府发债分别与消费和投资的关系,可以得出结论：从历史数据来看,李嘉图等价定理在我国并不适用。     

An Inframarginal Analysis of the Ricardian Model

This paper shows that a 2 × 2 Ricardian model has a unique general equilibrium, and the comparative statics of the equilibrium involve discontinuous jumps. If partial division of labor occurs in equilibrium, the country producing both goods would impose a tariff, whereas the country producing a single good would prefer unilateral free trade. If complete division of labor occurs in equilibrium, both countries would negotiate to achieve free trade. In a model with three countries, the country which does not have a comparative advantage relative to the other two countries, and/or which has low transaction efficiency, may be excluded from trade.     

The failure of Ricardian equivalence under progressive wealth taxation

Although the Ricardian Equivalence Theorem holds under a linear estate tax schedule, it fails to hold under a nonlinear estate tax schedule. In a representative consumer economy, a temporary lump-sum tax increase reduces contemporaneous consumption. If different consumers face different marginal estate tax rates because they leave bequests of different sizes, a lump-sum tax increase redistributes resources from consumers in low marginal estate tax brackets to consumers in high marginal estate tax brackets; aggregate consumption may rise, fall, or remain unchanged. These departures from Ricardian Equivalence hold more generally under any nonlinear tax on saving, wealth or income accruing to wealth.     

The Ricardian equivalence hypothesis: evidence from Bangladesh

In this paper, a probabilistic discrete choice approach is used to examine the influence of economic and non-economic factors on the choice of medical specialty by new physicians. A two level nested logit model is estimated that relaxes the independence from irrelevant alternatives assumption, and allows for a potentially more realistic pattern of substitution across specialty choices. The results from this specification are compared to those obtained from joint and conditional logit models. The findings, which are relatively robust across models, indicate that economic incentives play an important role in the specialty choice process, in particular, expected hours worked and medical school indebtedness. Physician tastes for specialties also appear to have an important influence.     

The globalization of poverty according to Malthus

Malthus began publishing in economics two centuries ago. His thoughts on income distribution and poverty are profound. Recently, more original findings on these issues have appeared, but can be viewed as rediscovering Malthus. His thought remains germane to the present debate on poverty and his foresight deserves respect.     

From endogenous growth to stationary state: The world economy in the mathematical formulation of the Ricardian system

We analyse international trade in a Pasinetti–Ricardo growth model in the world economy scenario in which several small trading countries coexist and international commodity prices are determined by the interplay of supply and demand amongst them. We demonstrate that all the trading countries eventually reach the stationary state, though this process is not monotonic and the dynamics of capital and population may actually push some countries towards the stationary state and others away from it. We also use our model to assess an argument which Malthus employed in the second edition of An Essay on the Principle of Population (1803) to support a policy of agricultural protectionism.     

Indivisibilities in the Ricardian model of trade

The idea that goods or factors of production may not be perfectly divisible has important implications for many areas of economics. This paper introduces both types of indivisibilities into the standard Ricardian model of international trade. Indivisibilities give rise to new results compared to the standard model with perfectly divisible goods and factors of production. Both types of indivisibility may result in complete specialisation even in autarky, while goods indivisibility may result in (ex ante) identical consumers consuming different bundles of goods, and hence enjoying different levels of welfare. Both types of indivisibilities lead to efficiency losses relative to the perfectly divisible case. International trade may eliminate efficiency losses resulting from indivisibility in the factors of production, but not those resulting from goods indivisibility. This suggests that the presence of indivisibilities leads to a second-best world, with the consequent implications for policy. The results of the paper are consistent with existing empirical evidence.     

The application of nonparametric tests to poverty targeting

Many otherwise successful social programs have limited outreach among the very poor. We show how a recently developed nonparametric test can detect this pattern of program participation. We apply the test to data on participation in a microcredit program in India and do find participation increasing in income among the poorest households in the region.     

Econometric diagnostics to distinguish between the IS curve and the Ricardian equivalence

In this article two different specifications of a macroeconomic model are analysed. The first model is the Keynesian IS (Investments–savings) curve. The second is derived from the New Classical Ricardian equivalence. Since the two specifications are observationally equivalent, including the same set of variables, the econometric diagnostics of the regression equations are used to differentiate between the two of them. Six statistical criteria are compared: serial correlation, heteroscedasticity, specification tests, fit, randomness, and normality. The results support much better Ricardian equivalence than the Keynesian IS model.     

Ricardian equivalence and the intertemporal Keynesian multiplier

We show that Keynesian multiplier effects can be obtained in dynamic optimizing models if one combines both price rigidities and a “non-Ricardian” framework where, due for example to the birth of new agents, Ricardian equivalence does not hold.     

Ricardian fiscal regimes in the European Union

The prevalence of different fiscal regimes is important both for practical policy reasons and to assess fiscal sustainability, notably for European Union countries. The purpose of this article is to assess, with a panel data set, the empirical evidence concerning the existence of Ricardian fiscal regimes in EU-15 countries. The results give support to the Ricardian fiscal regime hypothesis throughout the sample period, and for sub-samples accounting for the dates of the Maastricht Treaty and for the setting-up of the Stability and Growth Pact. Furthermore, electoral budget cycles also seem to play a relevant role in fiscal behaviour.

Ricardian productivity differences and the gains from trade

This paper evaluates the role of sectoral heterogeneity in determining the gains from trade. We first show analytically that in the presence of sectoral Ricardian comparative advantage, a one-sector sufficient statistic formula that uses total trade volumes as a share of total absorption systematically understates the true gains from trade. Greater relative sectoral productivity differences lead to larger disparities between the gains implied by the one-sector formula and the true gains. Using data on overall and sectoral trade shares in a sample of 79 countries and 19 sectors we show that the multi-sector formula implies on average 30% higher gains from trade than the one-sector formula, and as much as 100% higher gains for some countries. We then set up and estimate a quantitative Ricardian–Heckscher–Ohlin model in which no version of the formula applies exactly, and compare a range of sufficient statistic formulas to the true gains in this model. Confirming the earlier results, formulas that do not take into account the sectoral heterogeneity understate the true gains from trade in the model by as much as two-thirds. The one-sector formulas understate the gains by more in countries with greater dispersion in sectoral productivities.     

The effect of robust growth on poverty: a nonlinear analysis

Previous research has shown that economic growth should help to reduce the rate of poverty. However, a number of recent studies have found that the economic expansion of the 1980s had no statistically significant effect on aggregate poverty. It is shown that both a Threshold regression and a Fourier approximation provide a better empirical model of poverty than the standard linear model. It is noteworthy that the nonlinear specifications show a large and significant effect on poverty of the 1980s expansion.     

Redefining poverty: a sensitivity analysis

First, we discuss the adoption of the absolute standard by the federal government and then present six alternative definitions of poverty. The motivation for redefining poverty derives from a concern with incorporating some measure of relative deprivation. The next section, performs a sensitivity analysis comparing the poverty rates generated by the alternative measures of poverty to the official poverty rate. The purpose of this comparison is to elucidate misconceptions circumscribing current poverty discourse. In the concluding section, we briefly address the politics of poverty in the USA.     

A Ricardian excursion to Bermuda: an estimation of mixed strategy equilibrium

While there is a rich theoretical literature on mixed strategy equilibria, there has long been doubt with regard to the actual prevalence of scuh equilibria. The objective of this paper is to empirically demonstrate a mixed strategy equilibrum in a model of Ricardian rent generation. The oligopolistic resort hotel industry in Bermuda is used as the illustrative case.     

Classical Ricardian Theory of Comparative Advantage Revisited

According to the classical Ricardian theory of comparative advantage, relative labor productivities determine trade patterns. The Ricardian model plays an important pedagogical role in international economics, but has received scant empirical attention since the 1960s. This paper assesses the contemporary relevance of the Ricardian model for US trade. Cross-section seemingly unrelated regressions of sectoral trade flows on relative labor productivity and unit labor costs are run for a number of countries vis-à-vis the United States. The coefficients are almost always correctly signed and statistically significant, although much of the sectoral variation of trade remains unexplained.     

Ricardian equivalence and fiscal distortions in the Dominican Republic

This paper tests the Ricardian equivalence hypothesis in the context of the Dominican Republic (DR). The results rejected the Ricardian theorem but a weaker version is shown to have significant implications for the DR. If the government borrows to increase spending, private consumption is crowded out and the economy will suffer in the long run. The outcome is worst if the government borrows to deliver a tax cut. In particular, for every RD$ 1.00 of additional debt incurred to finance government primary spending, private consumption and gross domestic product (GDP) fall by a meaningful RD$ 2.15 and RD$ 1.15 respectively. If the debt is used to finance the tax cut, the fall is RD$ 2.15 in both consumption and output. Interestingly, if the government uses taxes to cover a budget deficit, the effect is neutral and consistent with Ricardian equivalence. The paper argues that fiscal distortions are in part responsible for these multipliers. Distortions are estimated to be 21 % coming from different sources including taxes evasion and fiscal drainage. These findings suggest that the DR could benefit from either reducing the level of fiscal distortions or the size and scope of the Dominican government. If, however, the government continues to pursue an active fiscal role under the current environment, it will generate an unnecessary burden to consumption and economic growth.
