changes in human capital and earnings inequality recent evidence from brazil 1 abstract this paper estimates changes in the rates of return to human capital across the earnings distribution using data from over a 10 year period for brazil it uses these estimates to simulate the separate impacts of changes in returns to skills and changes in the supply of skills on earnings inequality evidence points strongly to growing inequality in rates of return to education in brazil this finding suggests that recent macroeconomic and trade reforms have been of most benefit to the skilled rather than the unskilled supporting evidence points to an improved competitiveness in the labour market with workers increasingly rewarded for productivity however although increases in returns to education are more pronounced at the top of the earnings distribution this did not in practice led to increased inequality this is because levels of education and other labour market rewarded endowments have increased and offset the rate of return effect appropriate education policy is therefore an essentia

ecological economic viability as a criterion of strong sustainability under uncertainty strong sustainability according to the common definition requires that different natural and economic capital stocks be maintained as physical quantities separately yet in a world of uncertainty this cannot be guaranteed to therefore define strong sustainability under uncertainty in an operational manner we propose to use the concept of viability viability means that the different components and functions of a dynamic stochastic system at any time remain in a domain where the future existence of these components and functions is guaranteed with sufficiently high probability we develop a unifying and general ecological economic concept of viability that encompasses the traditional ecological and economic notions of viability as special cases it provides an operational criterion of strong sustainability under a mild form of uncertainty and for medium spatial and temporal scales we illustrate this concept and demonstrate its usefulness by applying it to livestock grazing management in semi arid rangelands publication ecological economic viability as a criterion of strong sustainability under uncertainty available from https www researchgate net publication 46490456 ecological economic viability as a criterion of strong sustainability under uncertainty accessed apr 3 2017

using genuine savings for climate policy evaluation with an integrated assessment model there has been a recent increase in efforts to develop broader models to assess the impact of climate change and climate change policies both in terms of impact measures beyond gdp and in terms of modelling complexity beyond dice rice models climate policies aimed at reducing co2 emissions can have impacts in multiple sectors of the economy and can change consumption levels over time we show how the sustainability indicator genuine savings can be endogenised within a general equilibrium model and used as a criterion for judging the impacts of such policies in terms of future well being differences in genuine savings rates between co2 emission reduction scenarios are discussed we show how a broader genuine savings based assessment of climate change can result in a re evaluation of the consequences and costs of inaction in terms of various climate change related policies and how multiple environmental and well being outcomes can be analysed within a unified modelling framework

trade liberalization and wage inequality abstract this paper studies empirically the link between trade liberalization and wage inequality in chile within the context of the heckscher ohlin samuelson hos model we use cointegration techniques to estimate the long run relationship between the skill premium in chile and product prices openness and factor endowments we find that the fall in the relative price of labor intensive goods helps explaining the increase in wage inequality in chile during the last two decades the increase in proportion of the labor force with college degree on the other hand tends to reduce wage inequality in chile openness measured as the volume of trade over gdp widens the wage gap between skilled and unskilled labor we offer some hypothesis on the elements that are behind this positive relationship between wage openness and inequality but no empirical work is done this area may be an interesting subject of research

who wants to globalize consumer tastes and labor markets in a theory of trade policy beliefs although the allure of consumption is the engine of globalization political economists have tended to ignore varying consumer tastes as a potential source of beliefs about trade policy this article develops a theory of trade policy preferences that adds the notion of varying consumer tastes to the standard labor market application of the heckscher ohlin trade model the theory which can explain trade preferences both across individuals and countries is supported by an empirical analysis of survey data from 41 nations heavy consumers of exportables are found to be more protectionist than heavy consumers of imports and import competing goods moreover citizens in countries with expensive tradable goods see trade liberalization as a remedy to the rents they pay for protectionism other findings also support the more conventional labor market side of the heckscher ohlin model

how does globalisation affect regional inequality within a developing country evidence from china developing countries are increasingly concerned about effects of globalisation on regional inequality this paper develops an empirical method for decomposing the contributions of two major driving forces of globalisation foreign trade and foreign direct investment fdi on regional inequality and applies it to china even after controlling for many other factors globalisation is still found to be an important factor contributing to the widening regional inequality the paper ends by investigating the role of factor market segmentations in aggravating the distributional effect of changing regional comparative advantages in the process of globalisation

trade liberalization and the skill premium in developing economies empirical evidence shows that while the skill premium narrowed in some developing countries following trade liberalization it widened in others or even exhibited non monotonic behavior this paper studies a simple dynamic general equilibrium trade model in which differences in initial conditions across developing countries play a key role in explaining the variety of skill premium behaviors differences in initial conditions in terms of skilled labor and physical capital emerge in the model due to differences in trade policies the model can generate non monotonic behavior for the skill premium following trade liberalization

combining fair pricing and capital requirements for non life insurance companies the aim of this article is to identify fair equity premium combinations for non life insurers that satisfy solvency capital requirements imposed by regulatory authorities in particular we compare target capital derived using the value at risk concept as planned for solvency ii in the european union with the tail value at risk concept as required by the swiss solvency test the model framework uses merton s jump diffusion process for the market value of liabilities and a geometric brownian motion for the asset process valuation is conducted using option pricing theory in this setting we study the impact of model parameters and corporate taxation on fair pricing solvency capital requirements and shortfall probability for different safety levels measured by the default put option value we show that even though corporate taxes can have a substantial impact on pricing and capital structure they do not affect capital requirements if the safety level is retained before and after taxation

the impacts of trade on the brazilian labor market a cge model approach abstract the paper assesses the impacts of trade liberalization on macroeconomic variables and labor market indicators in brazil the discussion comes out of an earlier debate on the role of trade liberalization in shaping labor market outcomes in the well known heckscher ohlin and stolper samuelson hos theorems to address these issues we use a computable general equilibrium cge modeling approach to model the patterns of export growth by sector and their effects on macroeconomic and labor market indicators overall our results show that trade liberalization contributes to improve economic welfare by means of greater output lower domestic prices and higher labor demand the benefits of this economic improvement tend however to be appropriated by the most skilled workers in the most trade oriented sectors contradicting the predictions of the hos theorems

trade liberalization and rising wage inequality in latin america reconciliation with hos theory abstract the paper puts forward the hypothesis that the transitory effects of trade liberalization on wage inequality can differ from the long run outcome in cases where the hos theory predicts a decline in wage inequality in the long run a temporary rise can nevertheless occur due to i the asymmetries in the speed of contraction in the import sector and expansion in other sectors and ii the capital skill complementarity in production the asymmetric contraction and expansion causes a transitory capital accumulation that boosts the relative and the real wage of skilled labor due to capital skill complementarity although the long run hos fundamentals are therefore dominated in the short run by the transient effects arising due to capital skill complementarity the observed rise in wage inequality is nonetheless consistent with the hos theory appropriately extended to a dynamic setting

pricing and capital allocation in catastrophe insurance abstract this paper studies multi line pricing and capital allocation by insurance companies when solvency matters to consumers capital is costly to hold and the average loss is uncertain in this environment product quality concerns lead firms to diversify across markets and charge high prices for risk that threatens company solvency even if the risk is unrelated to other asset risk price differences across markets are traced to differences in capital required at the margin to maintain solvency finally the paper shows that capital costs have significant effects on catastrophe insurance markets because of high marginal capital requirements

globalization and rural poverty as is common in most contentious public debates different people mean different things by globalization some interpret it to mean the global reach of new technology and capital movements some refer to outsourcing by domestic companies in rich countries others protest against the tentacles of corporate capitalism or us hegemony economic military or cultural in this chapter i shall limit myself to interpreting globalization simply as openness to foreign trade and long term capital flows i shall ignore here the important issues arising from the devastation caused to fragile economies by billions of dollars of volatile short term capital stampeding around the globe in herd like movements or the substantial poverty reducing potential of international unskilled labour flows from poor to rich countries even if allowed in temporary and regulated doses

openness and wage inequality in developing countries the latin american challenge to east asian conventional wisdom the experience of east asia in the 1960s and 1970s supports the theory that greater openness to trade tends to narrow the wage gap between skilled and unskilled workers in developing countries in latin america since the mid 1980s however increased openness has widened wage differentials this conflict of evidence is probably not the result of differences between east asia and latin america instead the conflict is probably the result of differences between the 1960s and the 1980s specifically the entry of china into the world market and perhaps the advent of new technology biased against unskilled workers

globalisation and unequalisation what can be learned from value chain analysis although many have gained from the process of globalisation there remains a stubbornly large number of people living in absolute poverty and a rise in inequality within and between countries the issue is thus not whether to participate in the global economy but how to do so in a manner which provides for sustainable and equitable income growth this study shows how value chain analysis can be used to chart the growing disjuncture between global economic activity and global income distribution and to provide causal explanations for this outcome in so doing value chain analysis provides valuable insights into policy formulation and implementation

environmental valuation under sustainable development environmentalism has evolved since the 1960 s from a concern with the preservation of wilderness in the american experience to a concern over pollution of human habitat throughout the industrialized world northern anxiety spread to the loss of tropical rainforests and biodiversity in the south where environmentalism evolved further in an encounter with indigenous interpretations conditions and priorities by the late 1980 s climate change emerged as a central issue in a now global discourse on the relationship between environment and development the principle of sustainable development that current needs are to be met as fully as possible while ensuring that the life opportunities of future generations are undiminished relative to present is now widely accepted this paper illustrates that incorporating environmental values per se in decision making will not bring about sustainability unless each generation is committed to transferring to the next sufficient natural resources and capital assets to make development sustainable 11 refs 3 figs

global inequality and international trade the paper analyses the effect of widespread trade liberalisation on global income inequality the analysis of the trend in global inequality during 1981 97 presented in the first part of the paper shows that the apparent growth of income inequality among countries conceals a process of convergence some developing countries achieved significantly faster economic growth than the advanced industrialised countries and though small in number they actually account for a majority of the population of the developing world thus international inequality i e the inequality of distribution of per capita incomes among the world s population in fact declined even though the inter country income inequality increased the analysis in the second part of the paper shows i that while improved trade performance did have a stimulating effect on growth performance of countries trade liberalisation had extremely varied effects on trade performance across countries and ii that the distribution of benefits and costs of trade liberalisation across countries has been such as to reduce international inequality without affecting inter country inequality copyright 2004 oxford university press

changing labor market conditions and economic development in hong kong the republic of korea singapore and taiwan china in the newly industrializing economies nies of hong kong the republic of korea singapore and taiwan china the entire working population has benefited from labor market institutions the east asian nies attained and maintained generally full employment improved their job mixes raised real earnings and lowered their rates of poverty this article reaches two principal conclusions first labor market conditions continued to improve in all four economies in the 1980s at rates remarkably similar to their rates of aggregate economic growth second labor market repression was not a major factor in the growth experiences of these economies in the 1980s it thus appears that labor market repression is neither necessary nor desirable for outward oriented economic development

industrialisation and the factor content of latin american exports of manufactures this article shows that latin american exports of manufactures that grow consistently over time arise from both traditional as well as policy induced sources of comparative advantage case studies for argentina colombia and venezuela show that manufactures originally developed for the domestic market were exported with consistent growth rates and came to represent an important proportion of total manufacturing exports the study also shows that inter country differences in the factor content of these exports reflect both differences in original resource endowments as well as the effects of industrialisation policy

trade liberalisation and poverty what are the links this paper asks whether a developing country s own trade liberalisation could translate into increased poverty and what information would be required to identify whether it will do so it plots the channels through which such effects might operate identifying the static effects via four broad groups of institutions households distribution channels factor markets and government and the dynamic issues of volatility long term economic growth and short term adjustment stresses an increase in the price of something a household sells labour good service increases its welfare thus the paper first explores the likely effects of trade liberalisation on the prices of goods and services taking into account the distribution sector also critical is whether trade reform creates or destroys markets trade reform is also likely to affects factor prices of which the wages of the unskilled is the most important for poverty purposes if reform boosts the demand for labour intensive products it boosts the demand for labour and wages and or employment will increase however not all developing countries are relatively abundant in unskilled labour and trade can boost demand for semi skilled rather than unskilled labour hence poverty alleviation is not guaranteed trade reform can affect tariff revenue but much less frequently and adversely than is popularly imagined even if it does it is a political decision not a law of nature that the poor should suffer the resulting new taxes or cuts in government expenditure opening up the economy can reduce risk and variability because world markets are usually more stable than domestic ones but sometimes it will increase them because stabilisation schemes are undermined or because residents switch to riskier activities the non poor can generally tide themselves over adjustment shocks from a liberalisation so public policy should focus on whether the initially poor and near temporary setbacks the key to sustained poverty alleviation is economic growth there is little reason to fear that growth will not boost the incomes of the poor similarly while the argument that openness stimulates long run growth has still not been completely proven there is every presumption that it will

the valuation of multiple claim insurance contracts this paper provides a closed form solution for the value of a multiple claim insurance contract that is subject to a deductible amount and or an upper limit on claims the solution is a time integral of european option prices the model provides three important insights first systematic risk in insurance policies is altered in the presence of deductibles and maximum indemnity levels second idiosyncratic risk affects policy valuation and the required rates of return on underwriting portfolios finally contrary to traditional actuarial intuition changes in the risk free interest rate may either increase or reduce policy values

trade and wage inequality local versus global comparative advantages this paper shows that disentangling the local and global dimensions of trade can be crucial to get a better understanding of the trade impact on wage inequality in particular it allows us to reconcile the empirical evidence with the heckscher ohlin samuelson predictions our focus here is on italy as for local trade within its own cone of diversification italy is specialised in the production of unskill intensive goods while for global trade with respect to the other cone of diversification it is mainly specialised in the production of skill intensive goods on the evidence of these specialisation patterns we point out that the local trade has a strong impact on wage inequality in particular in line with the heckscher ohlin samuelson predictions the local export performance reduces wage inequality as it favours blue collar workers as for global trade it affects and increases wage inequality through the export channel again consistent with the heckscher ohlin samuelson predictions

insurance cycles interest rates and the capacity constraint model insurance profits exhibit cyclical behavior that has been attributed to capital market constraints the authors show that changes in interest rates simultaneously affect the insurer s capital structure and the equilibrium underwriting profit depending upon asset and liability maturity structure capital market access and reinsurance availability insurers will be differently affected by changing interest rates the authors find that the average market response to changing interest rates roughly tracks market clearing prices these cyclical effects are enhanced for firms with mismatched assets and liabilities and more costly access to new capital and reinsurance this evidence supports the capacity constraint hypothesis copyright 1995 by university of chicago press

an environmental economic measure of sustainable development abstract a central issue in the study of sustainable development is the interplay of growth and sacrifice in a dynamic economy this paper investigates the relationship among current consumption sacrifice and sustainability improvement in a general context and in two canonical stylized economies we argue that the maximin value of utility measures what is sustainable and provides the limit to growth maximin value is interpreted as a dynamic environmental economic carrying capacity and current utility as an environmental economic footprint the time derivative of maximin value is interpreted as net investment in sustainability improvement it is called durable savings to distinguish it from genuine savings usually computed with discounted utilitarian prices

one sided sustainability tests with amenities and changes in technology trade and population abstract if an economy with multiple consumption goods including environmental amenities uniquely maximises present value with constant discounting it is unsustainable at some time if either of two measures augmented net investment or the change in augmented green net national product are zero or negative then augmented denotes that time is treated as a productive stock which includes in each measure the value of future exogenous changes in technology or terms of trade adjustments are found to make each measure a test for individual sustainability when population grows exogenously the practical and philosophical rationale for testing sustainability in a present value maximising and therefore fully prescribed development path is discussed

misspecification of capital asset pricing this study documents empirical anomalies which suggest that either the simple one period capital asset pricing model capm is misspecified or that capital markets are inefficient in particular portfolios based on firm size or earnings price e p ratios experience average returns systematically different from those predicted by the capm furthermore the abnormal returns persist for at least two years this persistence reduces the likelihood that these results are being generated by a market inefficiency rather the evidence seems to indicate that the equilibrium pricing model is misspecified however the data also reveals that an e p effect does not emerge after returns are controlled for the firm size effect the firm size effect largely subsumes the e p effect thus while the e p anomaly and value anomaly exist when each variable is considered separately the two anomalies seem to be related to the same set of missing factors and these factors appear to be more closely associated with firm size than e p ratios

price regulation in property liability insurance a contingent claims approach a discrete time option pricing model is used to derive the fair rate of return for the property liability insurance firm the rationale for the use of this model is that the financial claims of shareholders policyholders and tax authorities can be modeled as european options written on the income generated by the insurer s asset portfolio this portfolio consists mostly of traded financial assets and is therefore relatively easy to value by setting the value of the shareholders option equal to the initial surplus an implicit solution for the fair insurance price may be derived unlike previous insurance regulatory models this approach addresses the ruin probability of the insurer as well as nonlinear tax effects

trade openness and wage inequality evidence for malaysia this article examines the impact of trade openness on wage inequality in malaysia during the period 1984 1997 malaysia has operated a very open trade regime since the 1960s and has pursued aggressive import substitution and export supporting policies this development strategy is very different to that adopted in many other emerging economies where trade liberalisation has been associated with greater wage inequality the aim of the present study is to examine whether malaysia s more open approach to international trade has had a similar effect on wage inequality the results suggest in fact that this is not the case

trade technology and employment in south africa abstract south africa has become increasingly integrated with the global economy since the early 1990s and particularly after the ending of apartheid however this has not been associated with increased employment and high levels of unemployment are a major economic and social problem the paper considers the impact of trade and technological change on both the level and skill composition of manufacturing employment first a chenery type decomposition analysis of employment change is carried out and then labour demand functions are estimated econometrically both trade and technology are found to have had a negative impact on employment but these are only partial explanations of the low rate of employment growth

a critical reexamination of the empirical evidence on the arbitrage pricing theory this paper demonstrates that the roll and ross rr and other previously published tests of the apt are subject to several basic limitations there is a general nonequivalence of factor analyzing small groups of securities and factor analyzing a group of securities sufficiently large for the apt model to hold it is found that as one increases the number of securities the number of factors determined increases this increase in the number of factors with larger groups of securities cannot readily be explained by a distinction between priced and nonpriced risk factors as it is impermissible to carry out tests on whether a given risk factor is priced using factor analytic procedures the apt model as exposited by ross 17 18 and extended by huberman 9 has provided the basis of an extensive literature as for example brown and weinstein 1 chen 3 hughes 10 ingersoll 11 jobson 12 reinganum 15 roll and ross rr 16 and shanken 17 to mention but a few it has also been treated in a more general context by chamberlain and rothschild 2 our purpose here is not to comment on this collection of papers many of which are unpublished but to reexamine the evidence presented by rr and point out major pitfalls involved in the empirical methodology employed by them and others who have followed their lead rr claim that on theoretical and more importantly on empirical grounds arbitrage pricing theory apt is an attractive alternative to the capital asset pricing model capm the apt it is argued requires less stringent and presumably more plausible assumptions is more readily testable since it does not require the measurement of the market portfolio and may be better able to explain the anomalies found in the application of the capm to asset returns the acceptability of the apt like that of the capm or any other theory ultimately depends on its ability to explain the relevant empirical evidence our subsequent discussion will show that many of the prqblems associated with the capm are also present in the apt context and that its ability to explain the relevant empirical evidence is not markedly superior moreover it raises questions not only about the rr and related empirical investigations of the apt but also about the testability of that theory in the present state of the art a major part of the problem results from the necessity to break down the universe being analyzed through the apt model this is forced upon the investigator by the fact

net national product as an indicator of sustainability net national product nnp can potentially serve several objectives among others to measure value added and to be an indicator of welfare in the aftermath of the world commission on environment and development however it also seems important to investigate whether the concept of nnp can serve as an indicator of sustainability my point of departure following hicks 1946 ch 14 is therefore to require that nnp should measure what can be consumed in the present period without reducing future consumption possibilities and in line with this to argue that the nnp should equal the maximum per capita consumption level that can be sustained if sufficiently many facilitating assumptions are made then a concept of nnp that serves as an exact indicator of sustainability can easily be constructed for instance for a closed economy with a constant population a stationary technology and with only one capital good it follows that the present does not reduce future consumption possibilities if and only if it does not decrease the stock of the single capital good hence under the assumption that the one capital good k is identical to the one consumption good x nnp defined as y x k measures the maximal sustainable consumption at time t because then x y is equivalent to k the purpose of this note is to establish that with multiple capital goods it is not in general possible to construct an exact indicator of sustainability on the

information spillovers margins scale and scope with an application to canadian life insurance a model of the production of life insurance services is developed the focus is on price setting ability and the cost advantages from size and diversity the model characterizes insurers decisions on the face value and number of policies and the number of insurance lines the model is applied to canadian life insurance firms unit revenue cost margins average from 13 per cent to 40 per cent across lines of insurance these margins emanate from information spillovers generated by marketing activities cost advantages due to size are small but are substantial from diversity returns to scale average from 1 13 to 1 40 while returns to scope from offering multiple insurance lines average from 70 per cent to 100 per cent

the impact of china on latin america and the caribbean summary the rapid growth of china and its increased integration with the global economy is having both direct and indirect effects on the latin american and caribbean region the paper focuses on the impacts of china on latin american trade and foreign direct investment flows it identifies the main channels through which china s growth is affecting the region and undertakes a preliminary analysis of the impacts on development it is shown that there are winners and losers in the region both at the country and sector level

the valuation of multivariate contingent claims in discrete time models there are several examples in the literature of contingent claims whose payoffs depend on the outcomes of two or more stochastic variables familiar cases of such claims include options on a portfolio of options options whose exercise price is stochastic and options to exchange one asset for another this paper derives risk neutral valuation relationships rnvrs in a discrete time setting that facilitate the pricing of such complex contingent claims in two specific cases joint lognormally distributed underlying variables and constant proportional risk aversion on the part of investors and joint normally distributed underlying variables and constant absolute risk aversion preferences respectively this methodology is then applied to the valuation of several interesting complex contingent claims such as multiperiod bonds multicurrency option bonds and investment options

aggregating infinite utility streams with intergenerational equity the impossibility of being paretian it has been known that in aggregating infinite utility streams there does not exist any social welfare function which satisfies the axioms of pareto intergenerational equity and continuity we show that the impossibility result persists even without imposing the continuity axiom and in frameworks allowing for more general domains of utilities than those used in the existing literature

manufactured exports of developing countries and their terms of trade since 1965 abstract during the last 40 years since the prebisch singer terms of trade deterioration hypothesis was first proposed the commodity composition of exports of developing countries has undergone a major change in the direction of dominance of manufactures in their nonfuel exports with strong growth in the volume of their manufactured exports but this did not allow developing countries to escape unequal exchange relations with the industrial countries their barter terms of trade in manufactures showed signs of weakness rather than improvement and clearly failed to reflect the respective productivity trends leading to deterioration in factoral terms of trade

south south trade and skill premia contrary to the predictions of the 2 2 2 heckscher ohlin model empirical evidence shows that the skill premium increased in some developing countries and decreased in others after trade liberalisation this paper attempts to reconcile the empirical evidence with the theoretical predictions by introducing a model where south south trade can produce the observed patterns of skill premia in the south in this context south south trade expands the import range of the country that reduces the tariff this increases the demand for and the cost of skilled workers in the other country this also leads the country that reduces the tariff to expand its export range and reduce its import range therefore the country that reduces the tariff experiences an increase in its export range which leads to an increase in the skill premium as the impact on the import range is ambiguous it is possible that the other country experiences a decline in the skill premium thus trade liberalisation between southern countries can cause an increase in the skill premium in one and a decrease in the skill premium in another

revisiting the revisited terms of trade will china make a difference in challenging the conventional wisdom at the time singer and prebisch posited a number of explanations for declining terms of trade of developing economies including both country and product specific factors over the past decade we have begun to witness a simultaneous process of price differentiation within commodities with the prices of some commodities increasing and within manufacturing with the price of many manufactures falling these price changes may reverse the decline in the terms of trade of commodity producers the entry of china into the global market has played an important role in this augmenting the demand for many hard commodities its role as an exporter of manufactures coupled with concentration in global buying may undermine the prices of many manufactures

trade liberalisation in brazil creating or exporting jobs using the growth accounting and factor content approaches this article looks at the impact of trade liberalisation on the structure and level of employment in brazil over the 1990 97 period the results support the argument that trade liberalisation in developing countries have a negative short term impact on employment relatively small in brazil s case which tends to be outweighed in the long run by a more labour intensive output mix

on the impact of financial development on income distribution time series evidence financial market development is said to have equalizing or unequalizing effects on income distribution previous research used cross sectional and panel data and provided mixed results suspecting that they suffer from aggregation bias we adhere to time series data and error correction modeling technique and address the issue one more time in each of the 17 countries for which we have time series data in 10 counties short run effects of financial market development on income distribution were found to be equalizing in five countries the effects were unequalizing however the equalizing effects lasted into the long run only in three countries of denmark kenya and turkey

is there a social kuznets curve the influence of labour standards on inequality abstract this study empirically investigates the impact of core labour standards on income inequality for a range of 90 countries from 1990 2000 a synthetic index of labour standards is computed by means of a multiple correspondence analysis and no significant correlation is found with the gini index one of the reasons pointed out is that the effective implementation of core labour standards depends on the quality of the country s political and legal systems using instrumental variables in a tsls model we found an inverse u shaped curve between the new endogenous index of core labour standards and income inequality

a general approach to welfare measurement through national income accounting a framework is developed for analyzing national income accounting using a revealed welfare approach that is sufficiently general to cover both the standard discounted utilitarian and maximin criteria as special cases we show that the basic welfare properties of comprehensive national income accounting previously ascribed only to the discounted utilitarian case extend to this more general framework in particular under a wider range of circumstances it holds that real nnp growth or equivalently a positive value of net investments indicates welfare improvement we illustrate the applicability of our approach in the dasgupta heal solow model of capital accumulation and resource depletion

a dynamic analysis of human welfare in a warming planet anthropogenic greenhouse gas ghg emissions have caused atmospheric concentrations with no precedents in the last half a million years inducing serious uncertainties about future climates and their effects on human welfare recent climate science supports the view that the climate stabilization will require very low ghg emissions in the future we ask is a path of low emissions compatible with sustainable levels of human welfare with steady growth in human quality of life addressing these questions requires both defining welfare criteria and empirically estimating the possible paths of the economy we specify and calibrate a dynamic model with four intertemporal links education physical capital knowledge and the environment in line with nordhaus 2008a and with the stern review 2007 we assume that ghg emissions allow increased production while a higher stock of atmospheric carbon decreases production our index of human welfare which we call quality of life quol emphasizes education knowledge and the environment affected by greenhouse gas emissions in addition to consumption and leisure thus we avoid a consumptionist fallacy that welfare depends only on commodity consumption and perhaps leisure we reject discounted utilitarianism as a normative criterion and consider two alternatives the first is an intergenerational maximin criterion which maximizes the quality of life of the first generation subject to maintaining at least that level for all successive generations the second is human development optimization that seeks the maximization of the quol of the first generation subject to achieving a given constant rate of growth in all subsequent generations hence our analysis focuses on a human notion of sustainability as opposed to the conventional green sustainability limited to keeping the quality of the environment constant because our dynamic optimization programs defy explicit analytical solutions our approach has been computational as a benchmark we consider a simple model with physical and human capital for which we prove a turnpike theorem we then devise a computational algorithm inspired by the turnpike property to construct feasible although not necessarily optimal paths in the more complex and realistic model our analysis indicates that with ghg emission paths entailing very low emissions in the future positive rates of growth in quol are possible while the first generation experiences a quol higher than the historical reference level we also observe a tradeoff between the quality of life of the first generation and the rate of growth in the quality of life yet generation 1 s sacrifice for the sake of a higher growth rate appears to be small the paths that we compute involve investments in knowledge at noticeably higher levels than in the past

natural catastrophe insurance when should the government intervene this paper develops a theoretical framework for analyzing the decision to provide or buy insurance against the risk of natural catastrophes in contrast to conventional models of insurance the insurer has a non zero probability of insolvency which depends on the distribution of the risks the premium rate and the amount of capital in the company when the insurer is insolvent each loss reduces the indemnity available to the victims thus generating negative pecuniary externalities our model shows that government provided insurance will be more attractive in terms of expected utility as it allows these negative pecuniary externalities to be spread equally among policyholders however when heterogeneous risks are introduced a government program may be less attractive in safer areas which could yield inefficiency if insurance ratings are not chosen appropriately

pricing in microinsurance markets summary microinsurance markets have exhibited strong growth rates in recent years great parts of the industry are however challenged by fundamental issues of providing insurance products one of the most significant of which is pricing risk in this paper we provide a nontechnical analysis of insurance pricing problems and a review of the set of opportunities that can address some of the specific pricing constraints in microinsurance markets a key contribution of this paper is the investigation of conventional techniques as potential solutions for improving the pricing of insurance risk in microinsurance markets

export processing zones in the dominican republic transforming manufactures into commodities this paper examines the performance of export processing zones in the dominican republic it shows that in specializing in unskilled labor intensive export processing in the context of competitive devaluations between central american countries the dominican republic has experienced immiserizing employment growth in these circumstances the export of labor intensive manufactures is akin to that of primary commodities exporting countries which rely on unskilled labor and which fail to make the transition to higher value added production exports are thus likely to experience declining terms of trade the conclusions of this case study are considered to have wider relevance to world bank and international monetary fund inspired structural adjustment programs in the region

skill biased technology transfer around the world in this paper we consider the extent to which skill biased technological changes are transferring across international borders thereby altering the skill structure of labour markets evidence of increased relative demand for skilled workers is uncovered in the manufacturing sectors of 37 high middle and low income countries skill biased technology transfer is central to the increased demand for skilled workers in middle income countries in low income countries there is less evidence of such a mechanism operating

numerical valuation of high dimensional multivariate european securities we consider the problem of pricing a contingent claim whose payoff depends on several sources of uncertainty using classical assumptions from the arbitrage pricing theory the theoretical price can be computed as the discounted expected value of future cash flows under the modified risk neutral information process although analytical solutions have been developed elsewhere for a few particular option pricing problems computing the arbitrage prices of securities under several sources of uncertainty is still an open problem in many instances in this paper we present efficient numerical techniques based upon monte carlo simulation for pricing european contingent claims depending on an arbitrary number of risk sources we introduce in particular the method of quadratic resampling qr a new powerful error reduction technique for monte carlo simulation quadratic resampling can be efficiently combined with classical variance reduction methods such as importance sampling our numerical experiments show th

the determination of fair profits for the property liability insurance firm although the property liability insurance industry has been subject to price regulation for many years surprisingly little research has been directed at producing valuation models of a property liability insurance firm although property liability price regulation has historically involved setting minimum prices to reduce the risk of insolvency some commissions have begun to move toward setting prices more in the spirit of public utility regulation 1 if in an effort to promote efficiency the working objective of such regulation requires the determination of prices that would prevail under competition then regulation must be founded on some model of the costs of regulated firms under competition with free entry prices just cover all economic costs including the opportunity costs of investment by suppliers of capital and a valuation model is required to explain how the market value of the firm and therefore the cost of capital reacts to changes in the prices it charges our objective in this chapter is to provide such a framework

rational insurance purchasing consideration of contract nonperformance much of the analysis of rational insurance purchasing and hedging strategies has been undertaken on the basis of the expected utility hypothesis this decision framework has been used to reformulate the bernoulli principle that a risk averter rationally would fully insure at a fair premium other applications include the analysis of insurance at unfair premiums mossin 1968 and smith 1968 the effects of state dependent utility on the rational insurance purchase cook and graham 1977 the effects of risky background wealth doherty and schlesinger 1983 and mayers and smith 1983 and the design of the optimal insurance policy raviv 1979 such analyses have been conducted on the assumption that insurance policies are free of insolvency default risk this assumption stands in sharp contrast to the actuarial literature in which the insolvency risk or probability of ruin is a central focus of attention

capital and risk in property liability insurance markets abstract this paper investigates the capital and portfolio risk decisions of property liability insurance firms a theoretical model based on option pricing theory is developed which predicts a positive relationship between insurer capital and risk as firms balance these two factors to achieve their desired overall insolvency risk the implications of the model are then tested empirically using a simultaneous equations methodology the results support the predictions of the model they also provide evidence that managerial incentives play a role in determining capital and risk in insurance markets the findings have significant implications for insurance solvency regulation

maximin viability and sustainability the maximin criterion defines the highest utility level that can be sustained in an intergenerational equity perspective the viability approach makes it possible to characterize all the economic trajectories sustaining a given not necessarily maximal utility level in this paper we exhibit the strong links between maximin and viability we show that the value function of the maximin problem can be obtained in the viability framework and that the maximin path is a particular viable path this result allows us to extend the recommendations of the maximin approach beyond optimality to characterize the sustainability of economic trajectories which differ from the maximin path attention is especially paid to non negative net investment at maximin accounting prices which is shown to be necessary to maintain the productive capacity of the economy whether the development path is optimal or not our results provide a new theoretical ground to account for sustainability in imperfect economies based on maximin prices

a picture of wage inequality and the allocation of labor through a period of trade liberalization the case of brazil this paper constructs a picture of the labor market impact of trade liberalization in brazil we examine the level and dispersion of wages the skilled wage premium and employment composition before and after trade liberalization after trade reform there was a rise in the returns to college education which since the share of college workers also rose is attributable to rising demand this change did not increase overall wage dispersion because of the small share of college educated workers and because of decreasing returns to intermediate levels of education

sustainability of an economy relying on two reproducible assets evaluating the sustainability of a society requires a system of shadow or accounting values derived from the sustainability objective as a first step toward the derivation of such shadow values for a maximin objective this paper studies an economy composed of two reproducible assets each producing one of two consumption goods the effect of the substitutability between goods in utility is studied by postulating in turn neoclassical diminishing marginal substitutability perfect substitutability and perfect complementarity the degree of substitutability has strong effects on the maximin solution affecting the regularity or non regularity of the program and on the accounting values this has important consequences for the computation of genuine savings and the sustainability prospects of future generations

the equilibrium valuation of risky discrete cash flows in continuous time this paper values a contingent claim to discrete stochastic cash flows generated by a poisson arrival process with a randomly varying intensity parameter in the most general case both the size and the arrival intensity of cash flows may correlate wih state variables in a continuous time economy assuming the conditions of an intertemporal capital aset pricing model solutions for the value of the contingent claim can be found using various techniques the paper suggests immediate applications to the valuation of insurance contracts the decision to build a firm with unknown future investment opportunities and the pricing of mortgage backed securities

channels and policy debate in the globalization inequality poverty nexus the process of globalization has led to a much greater integration of the world economy the flows of trade capital labour technology and information across national borders have accelerated since the 1980s and created an environment conducive to faster economic growth and transmission of knowledge it is evident that the forces of globalization provide a strong potential for a major reduction in poverty in the developing world however for a number of reasons brought out in this chapter the positive impact of globalization on poverty alleviation worldwide has not been as substantial as one might have expected in this chapter we explore structural factors and policies within the world economy and national economies that impede the full transmission of the benefits of the various channels of globalization to poverty reduction

yes the apt is testable the arbitrage pricing theory apt has been proposed as an alternative to the meanvariance capital asset pricing model capm this paper considers the testability of the apt and points out the irrelevance for testing of the approximation error we refute shanken s objections including his assertion that roll s critique of the capm is applicable to the apt we also explain the testability of the apt on subsets and we explore the relationship between the apt and the capm the arbitrage pricing theory apt has been the subject of extensive research efforts since it was introduced by ross 36 37 the research has included theoretical papers and a growing empirical literature 2 nonetheless there seems to be some confusion in the literature about the relation between the theoretical underpinnings of the apt and its empirical tests this paper is an attempt to alleviate the confusion to illustrate the issues and to provide a focus section i of this paper is devoted to examining and refuting some points raised in shanken 40 which considers the testability of the apt the underlying premise of the apt is that asset returns ri are generated by a factor model of the form

arbitrage pricing theory and utility stock returns this paper presents some new evidence that arbitrage pricing theory may lead to different and better estimates of expected return than the capital asset pricing model particularly in the case of utility stock returns results for monthly portfolio returns for 1971 1979 lead to the conclusion that regulators should not adopt the single factor risk approach of the capm as the principal measure of risk but give greater weight to apt whose multiple factors provide a better indication of asset risk and a better estimate of expected return notwithstanding initial skepticism and recent challenges the capital asset pricing model capm has been used to develop project screening rates value companies measure the impact of policy change on risk and construct portfolios recently the federal energy regulatory commission ferc proposed it as the principal measure of risk for the electric utilities it regulates it would be ironic for acceptance of capm by policymakers to occur just as arbitrage pricing theory apt threatens to replace it as an explanation of the relationship between return and risk and it would be a pity if ferc were to adopt the single risk factor approach of capm when it could be demonstrated that the multiple factors of apt provide a better indication of asset risk and a better estimate of expected return this paper presents some new evidence that apt may lead to different and better estimates of expected return than capm and that it may be more helpful to policymakers as a result we describe capm and apt note work done by others show how estimates of required returns for utilities developed by applying each model may differ and finally report the evidence that convinces us that if one model is to be relied upon for policy purposes apt would be the better choice

calm after the storms after rising during most but not all ofthe 1960 85 period inequality in chile seems to have stabilized since around 1987 following the stormy period of economic and political reforms of the 197

interest rates and insurance price cycles abstract property liability insurance prices and profits appear to move in a six year cycle the common explanation for the cycle amongst many industry analysts is that the insurance market is inherently unstable and that prices fail to converge on clearing levels our explanation is different we identify spot equilibrium prices using the capital asset pricing model but informational regulatory and contractual lags preclude instantaneous adjustment we therefore model the temporal movement of prices using a partial adjustment model in which actors form rational expectations the actual movement of insurance prices does seem to track closely those estimated by the partial adjustment model the cycle may be better viewed as a series of converging responses to changing spot prices

on sustainability and social welfare abstract this paper proposes to define sustainability in terms of leaving it possible for future generations to sustain certain defined targets it is shown that variants of genuine savings and the ecological footprint can then serve as indicators of sustainability the link between sustainability and intergenerational welfare is examined and it is shown how to incorporate indicators of sustainability into a social welfare measure including risk in the analysis

technology trade and factor prices abstract the view that recent changes in the distribution of income primarily reflect technology rather than trade may be the majority opinion but has been harshly criticized by some trade economists this paper will argue that the critique in fact misses the point essentially because the critics undertake the wrong thought experiments trade volumes are not irrelevant if one poses the question correctly one immediately realizes that small trade volumes are inconsistent with a story that attributes large distributional effects to trade the factor bias of technological change is not immaterial except in the case where such change takes place in a small open economy as opposed to one that can affect world prices and where technical change occurs only in that economy rather than occurring simultaneously in other economies as well since the real situation does not meet either criterion factor bias definitely does matter most surprisingly the much maligned use of a factor content approach to infer the effects of trade on factor prices turns out to be an entirely justified procedure when carefully applied

sustainability constraints versus optimality versus intertemporal concern and axioms versus data sustainable sustained or survivable development are defined here as distinct sustainability constraints on intertemporal distribution in a context which ignores uncertainty environmental and intratemporal concerns such constraints are neither self contradictory nor redundant for they can conflict with maximizing the present value of utility optimality nor inferior since the axioms underlying optimality are ethically arbitrary and refuted by empirical psychological data axiomatic arguments may clarify but cannot resolve debates about intertemporal concerns data suggest that sustainability constraints are not respected and that intertemporal welfare functions containing a preference for sustained improvement may better reflect what bodies politic mean by sustainability

genuine saving and positional externalities much evidence suggests that people are concerned with their relative consumption yet positional externalities have so far been ignored in savings based indicators of sustainable development this

globalization and upgrading what can and cannot be learnt from international trade statistics in the wood furniture sector the measurement of innovation is a complex and ambiguous challenge two broad families of measures have been used those focusing on inputs and those focusing on outputs each has its strengths and weaknesses but neither is able to capture the growing importance of product innovation adequately in this paper we attempt to throw more light on the measurement of product innovation through the complementary use of data on unit price and market share the analysis is distinctive through its exclusive use of trade data these measures are applied to the global furniture industry through an analysis of imports into the eu between 1989 and 2001

assessing risky social situations this paper reexamines the welfare economics of risk it singles out a class of criteria the expected equally distributed equivalent as the unique class that avoids serious drawbacks of existing approaches such criteria behave like ex post criteria when the final statistical distribution of well being is known ex ante and like ex ante criteria when risk generates no inequality the paper also provides a new result on the tension between inequality aversion and respect of individual ex ante preferences in the vein of harsanyi s aggregation theorem

globalisation history and development a tale of two centuries this paper situates globalisation in historical perspective to analyse its implications for development it sketches a picture of globalisation during the late nineteenth and twentieth centuries a comparison of these two epochs reveals striking parallels unexpected similarities and important differences it shows that globalisation did not lead to rapid growth and economic convergence in the world either then or now indeed growth slowed down and income levels diverged while the gap between the industrialised and developing countries widened in both epochs the story of globalisation it turns out does not conform to the fairy tale about convergence and development

economic policy changes and wage differentials in latin america abstract this article presents estimates of the impact of changes in liberalization policies on wage differentials by schooling level using a new high quality data set for 18 latin american countries for 1977 98 the method controls for all fixed and time varying country characteristics some of which may affect the policies themselves the results indicate that liberalizing policy changes overall have had a short run disequalizing effect of expanding wage differentials although this effect tends to fade away over time this disequalizing effect is due to the strong impact of domestic financial market reform capital account liberalization and tax reform however privatization contributed to narrowing wage differentials and increasing trade openness had no significant effect on wage differentials technological progress rather than trade flows appears to be a channel through which policy changes are affecting inequality

fair insurance guaranty premia in the presence of risk based capital regulations stochastic interest rate and catastrophe risk abstract a multiperiod model is developed to measure the costs posed to the guaranty fund in a setting that incorporates risk based capital regulations interest rate risk and the possibility of catastrophic losses the guaranty contract is modeled as a put option on the asset of the insurance company with a stochastic strike price and an uncertain maturity the impacts of the key factors of this model are examined numerically and shown to make material differences in the costs to the guaranty fund

the personal and the factor distributions of income in a cross section of countries abstract the shares of capital and labour in national income vary substantially both over time and across countries this paper shows that the factor distribution of income is an essential determinant of the personal distribution of income we use cross country and panel data for a group of developed and developing countries to show that a larger labour share is associated with a lower gini coefficient of personal incomes this effect is not only statistically significant but also economically important an increase in the labour share in mexico to that observed in the us would reduce the gini coefficient of the former by between two and five points

a disaggregated analysis of eu imports the implications for the study of patterns of trade and technology this paper examines trends in the unit prices of manufactured imports into the european union eu in the period 1988 2002 this is undertaken at a high level of disaggregation and it is this decomposition which we believe has important implications both for a range of bodies of economic analysis and for policy the analyses undertaken in this paper confirm that disaggregation matters in helping to identify unit price trends we have also shown that unit price trends vary with the type of economy exporting into europe and the type of product being exported and that these results are robust at high levels of disaggregation

a characterization of sustainability with indicators abstract economists favor the use of criteria to characterize sustainability in practice policy makers use indicators i e measurements based on the current economic state and decisions representing given sustainability issues in this paper i introduce a criterion characterizing sustainability with indicators and thresholds acting as constraints i interpret the thresholds as minimal rights to be guaranteed to all generations and define sustainable trajectories as those satisfying all the constraints at all times the new criterion is a generalized maximin criterion the approach is applied to a simple production consumption economy with non renewable resources to derive some policy recommendations on the use of indicators to deal with sustainability i discuss the implications of such a criterion in terms of trade off between sustainability thresholds efficiency and time consistency in particular the resulting problem is time inconsistent and sustainability thresholds may be revised over time following the time inconsistent policy based on indicators with dynamic revision of the thresholds may however result in a sustained utility path and even in utility growth
