On the Transmission Mechanism of Monetary Constraints to the Real Side of the Economy

Contrary to the predictions of the theory underlying international finance, inflows of capital triggered by financial liberalisation have neither equalised real interest rates nor increased income growth in many emerging economies. We explain this puzzle by developing a model that combines the balance‐of‐payments constraint approach to economic growth with a less stringent version of the real interest rate parity hypothesis. The model’s foundations are based on robust empirical findings or well‐established macroeconomic models. We show that a perverse combination of income elasticities of demand for imports and exports generates slow income growth and high real interest rates. As domestic income grows and imports rise faster than exports, the real exchange rate is expected to depreciate in order to clear the balance of payments (or the foreign exchange rate market). An incipient capital outflow arises and interest rates increase. Faster adjustment in capital rather than in the goods market therefore generates a higher real interest rate differential between the domestic small open‐economy and the rest of the world. The long run analysis shows that a constant degree of risk aversion implies a positive equilibrium real interest rate differential that affects economic growth. A permanent increase in default risk driven by persistent current account imbalances thus impacts on long run growth. The model’s results are illustrated with evidence from the three major Latin America economies: Argentina, Brazil and Mexico.     

Using Elasticities to Derive Optimal Income Tax Rates

This paper derives optimal income tax formulas using compensated and uncompensated elasticities of earnings with respect to tax rates. A simple formula for the high income optimal tax rate is obtained as a function of these elasticities and the thickness of the top tail of the income distribution. In the general non-linear income tax problem, this method using elasticities shows precisely how the different economic effects come into play and which are the key relevant parameters in the optimal income tax formulas of Mirrlees. The optimal non-linear tax rate formulas are expressed in terms of elasticities and the shape of the income distribution. These formulas are implemented numerically using empirical earning distributions and a range of realistic elasticity parameters.     

Simultaneous estimation of income and price elasticities of export demand,scale economies and total factor productivity growth for Brazil

This article focuses on a growth model in which (unlike other models) low (high) export demand elasticities and the fact that developing countries are importers of capital goods help explaining the slow (high) growth of these countries in the transition and in the steady state. The question arises whether export demand elasticities are low or high. For answering this question, export demand elasticities for the case of Brazil are obtained by estimation of the model. As a by-product of estimating the model, we obtain estimates for total-factor productivity growth and for scale economies. Based on the results from estimation we calculate steady-state growth rates, engine and handmaiden effects of growth as well as dynamic steady-state gains from trade. The model and the results are discussed in regard to several strands of literature.     

External income shocks and Turkish exports: A sectoral analysis

This study assesses how the growth rates of Turkish trading partners affected Turkish exports in various sectors for the period 1996:01 to 2009:12. To determine this, we modeled the destination countries and the export demand for each sector separately. Each model is estimated as a system of equations, where each equation represents a country using a seemingly unrelated regression method. The empirical evidence suggests that Motor Vehicles, Basic Metals, and Radio–Television are the sectors with the highest income elasticities for most of the analyzed countries, whereas the Food Products and Beverages sector has the lowest income elasticity. We also performed simulations for the effect of a 1% increase in the growth rate of each country on Turkish exports.     

Export demand elasticities and productivity as determinants of growth: estimates for Mauritius

In this article, we combine the export led and import led growth hypotheses in a growth model in which the importation of foreign capital goods and the demand elasticities of own export products explain the growth opportunities and the technical progress of developing countries. This model, based on imported capital goods, uses Mauritius’ data on capital investment, employment, export partners’ growth and terms of trade to estimate price and income elasticities of export demand, total factor productivity growth and economies of scale. These elasticities are then used to assess how the growth in export partners’ income is converted into domestic growth. The implications of the presence of low or high export demand elasticities are discussed by relating them to various strands of trade and growth literature. Based on the results of this estimation, we also calculate steady state growth rates, engine and handmaiden effects of growth as well as the dynamic steady state gains from trade for this latecomer export economy. The implications of steady state results are also discussed in the light of the Mauritian employment and growth perspectives.     

ON THE ESTIMATION OF GROWTH AND INEQUALITY ELASTICITIES OF POVERTY WITH GROUPED DATA

After decades of intensive research dedicated to efficient and flexible parametric statistical distributions, the lognormal distribution still enjoys, despite its empirical weaknesses, widespread popularity in the applied literature related to poverty and inequality analysis. In the present study, we emphasize the drawbacks of this choice for the calculation of the elasticities of poverty. For this purpose, we estimate the growth and inequality elasticities of poverty using 1,132 income distributions, and 15 rival assumptions on the shape of the income distributions. Our results confirm that the lognormal distribution is not appropriate in most cases for the analysis of poverty: the magnitude of the elasticities is generally overestimated and the estimation of the relative impact of growth and redistribution on poverty alleviation is biased in favor of the growth objective.     

Elasticities of rate schedule parameters

The rate schedules for services provided by regulated industries are often not defined in terms of simple per-unit charges but as multipart tariffs. For example, in the case of block price rates, the rate parameters are the definition of the block limits and the per-unit charges in each block. The analysis of these rates is complicated by the fact that most econometric models provide only per-unit or marginal-cost-based elasticities. This paper presents a technique for determining the rate schedule elasticities from elasticities for functions of the rate schedule parameters such as per-unit price elasticities. Also presented are methods for determining elasticities for combinations of service characteristics and the price schedule parameter elasticities for an entire service market. Examples are given for block water rates and Hopkinson and time-of-day electricity rates.     

Product cannibalization and the role of prices

The role of brand prices in contributing to product cannibalization is examined. Price elasticities and reference price theory are used to provide a theoretical foundation and empirical test for the impact of a firm's cheap brand on one of its expensive brands. Results are consistent with the conclusion that the market share of the company's premium brand was cannibalized by a growth in sales of its cheap brand.     

Global restrictions on the parameters of the CDES indirect utility function

This paper extends the analytical and empirical application of the basic indirect utility function of Houthakker–Hanoch—called the CDES specification (constant differences of elasticities of substitution). The non-homothetic CDES preferences are the natural parametric extension on the global domain of the homothetic CES preferences with many commodities, and CDES can conveniently be used in specifying CGE multisector models with a demand side satisfying observable Engel curve patterns. Moreover, all Marshallian own-price elasticities are no longer restricted to exceed one, and positive and negative cross-price effects are allowed for in empirical demand analyses. Explicit calculations of the Allen elasticities of substitution are instrumental in demonstrating the economic implications of the parameters of indirect utility functions with global regularity properties and flexibility of the derived demand systems.     

Shipping the good fish out? An empirical study on the EU seafood imports under the EU’s Generalized System of Preferences

The impact of the EU (European Union) Generalized System of Preference (GSP) on the relative EU’s demand for seafood quality was evaluated in the study. We first explored the theoretical Alchian–Allen result of change in ad valorem tariffs in an n–good world, and then tested this result in the empirical study. The theoretical analysis suggests that whether a reduced ad valorem tariff in an n–good case raises the relative demand for high-value goods depends not only on the substitutability between high-value and low-value goods but also on the substitutability between these similar goods with their weak substitutes. In the empirical sections, we first estimated the elasticities of the substitutions and then used these elasticities to evaluate the quality composition of the EU’s seafood imports from the beneficiary countries. The empirical results in general confirm the occurrence of ‘shipping the good fish out’ due to the reduced tariff rates under the EU’s GSP arrangements.     

Meat and fish consumption patterns in Saudi Arabia

This study analyses the demand for meat (beef, chicken and lamb) and fish in Saudi Arabia in a system-wide framework using data for the period 1985–2010. A preliminary data analysis reveals that, in Saudi Arabia, the relative consumption of beef, chicken and fish has a positive growth, while lamb has a negative growth. The average relative price growth rates of beef, chicken and fish are negative, while that of lamb is positive. The expenditure shares of beef, chicken and fish have increased while that of lamb has fallen. The estimation results of the demand system reveal that there is an autonomous trend out of lamb into beef, chicken and fish. The implied income elasticities indicate that beef, lamb and fish are considered to be luxuries, while chicken is a necessity. The demand for all meat products and fish are price inelastic. These elasticities are key inputs for policy analysts in terms of devising policies in relation to meat production, meat imports, taxation and food security issues in Saudi Arabia. The usefulness of the implied elasticities is demonstrated by simulating the consumption of beef, chicken, lamb and fish under various policy scenarios.     

Estimating a Dynamic Model of Household Choices in the Presence of Income Taxation

The purpose of the article is to study the incentive and distributional consequences of income taxation. The article analyzes tax changes in a dynamic setting. The framework is estimated under a set of different identifying assumptions using parametric, nonparametric, and semiparametric techniques. The empirical results focus on tax reforms in Germany in the 1980s. The article shows that these reforms did not significantly lower effective tax rates. The findings also suggest that estimated elasticities for male labor supply are small, ranging between 0.02 and 0.2.     

Growth, Expansion of Markets, and Income Elasticities in World Trade

The Houthakker–Magee effect implies that a country facing unfavorable income elasticities in trade must either grow at a slower rate than its trading partners or experience a trend worsening of the current account and/or depreciation of the real exchange rate. Krugman (1989 ) first documented the existence of a "45-degree rule" under which income elasticities are systematically related to growth rates. I develop a model which is a generalization of Krugman (1989 ) in several dimensions (including intertemporal). The intertemporal assumption of equal consumption growth for individuals across countries and the assumption of no intertemporal trade can be viewed as two extreme benchmarks. Empirical tests of the various 45-degree rules suggest that it is misleading to treat income elasticities as structural, as is commonly done in forecasts of current account movements. The data also seem to be more consistent with the benchmark of no intertemporal trade than that of complete intertemporal trade.     

Australia's Unemployment Problem

A number of Australian studies have provided microeconomic and macroeconomic perspectives on the causes of, and solutions to, Australia's unemployment problem. This paper provides an evaluation of these studies. Several important findings can be noted. First, from the cross-sectional studies economists have gained a good understanding of the factors contributing to a high probability of unemployment. Effective use is currently being made of this information. Second, there is general consensus from the time-series studies regarding the estimates of the aggregate labour demand wage and output elasticities. In addition, it has been widely acknowledged that lower real wages and economic growth would help reduce the high rate of unemployment. Despite the information available we are making slow progress towards reducing the unemployment rate. This may be due to political reasons or because we are unsure of how to deliver the wage cuts and faster rates of economic growth presented as solutions to the unemployment problem.     

人民币升值能解决美国对华贸易赤字吗?——基于1994～2005年间月度数据的贸易弹性分析

文章以1994年1月到2005年3月的月度数据为样本,用ARDL框架下的协整方法,对中美贸易的收入弹性和实际汇率弹性进行了经验分析。分析后发现:第一,我国对美进出口的收入弹性都是显著的,并且我国对美国出口的收入弹性约为我国从美进口的收入弹性的6倍,但是我国对美进口和出口的实际汇率弹性都是不显著的。因此,文章认为人民币汇率对中美贸易没有显著影响,人民币汇率升值将无法改善美国的对华贸易收支。     

International trade and firms' attitude towards risk

This paper examines the optimal production and trade decisions of the domestic firms facing uncertainties owing to the exchange rate volatility under mean-variance preferences. The impact of uncertain exchange rate fluctuations on trade is evaluated in a partial equilibrium framework, using the concept of risk-aversion elasticities. These elasticities measure how sensitive the firms are towards substituting between return and risk at the margin, with respect to changes in the distribution of the spot exchange rate. This simplest possible analytical framework is useful for explicit empirical estimation of risk-aversion elasticities in the literature of international economics.     

ARE SERVICES INCOME-ELASTIC? SOME NEW EVIDENCE

The hypothesis that the demand for services is income-elastic tended to find support in early empirical work. Recent studies however, adopting improved methodologies and better international data (based on PPP exchange rates), have challenged this conventional wisdom. Using an updated, disaggregated dataset covering 60 countries in 1980 this paper re-estimates income and price elasticities of demand for services. It rejects the income-elastic argument overall but confirms a wide range of income elasticity estimates (above and below unity) across different types of services. Estimates are also shown to be sensitive to the a priori model of service demand.     

Taxation and top incomes in Canada

We estimate the elasticity of reported income with respect to tax rates for high earners using sub‐national variation across Canadian provinces. We argue this allows for better identification of tax elasticities than the existing literature. We find that elasticities of reported income at the provincial level are large for incomes in the top 1%, but small for lower earners. There are strong indications that the response happens both through earned and capital income. While our estimated elasticities are large, changes in tax rates cannot explain much of the overall long‐run trend of higher income concentration in Canada.     

Weight-based pricing in the collection of household waste: the Oostzaan case

This paper provides an empirical analysis of the effects of weight-based pricing in the collection of household waste. Using a comprehensive panel data set on all households in a Dutch municipality we estimate short-run as well as long-run price effects for the amounts of both compostable and non-recyclable household waste. We find significant and sizeable price effects, with the elasticity for compostable waste being four times as large as the elasticity for non-recyclable waste. Long-run elasticities are about 30% larger than short-run elasticities.     

Using Empirical Point Elasticities to Teach Tax Incidence

Using point elasticities rather than using either arc elasticities or slopes of demand and supply curves provides the best method for teaching students about the economic impacts of excise taxes. Not only does a point-elasticity approach simplify theoretical analysis of tax impacts, but it also allows instructors to take advantage of publicly available empirical estimates of demand and supply elasticities to show students how theoretical results can be applied to real-world tax policy issues. To illustrate these advantages, the authors use several available estimates of point elasticities of demand and supply of raw sugar to calculate the economic impacts of a recently proposed penny-per-pound tax on raw cane sugar grown in the Florida Everglades.
