efficient methods of measuring welfare change and compensated income in terms of ordinary demand functions a utility maximizing consumer with a completely known system of ordinary demand functions q h p c is considered let p qo and p q be two arbitrary equilibrium situations the problem is to evaluate in which of the situations the utility is higher without knowing the utility function revealed preference theory tells that the ordinary demand functions which are in principle observable contain enough information to solve the problem remaining difficulties are therefore mainly computational we present how the compensated income c i c p qo and the compensated demand h p cl1 are calculated with arbitrary accuracy using only the ordinary demand system our two efficient algorithms also have interesting interpretations in terms of index numbers and consumer surplus measures

how should control theory be used to calculate a time consistent government policy we study different solutions to a simple one dimensional linear quadratic game with a large number of private agents and a government a time consistent solution is defined as a solution to the hamilton jacobi bellman equation i e as a policy for which the government has noprecommitment capability this solution is compared to a policy where the government has an instantaneous pre commitment i e an equilibrium in which the government has a period by period leadership in both cases we show how control theory should be applied to calculate the equilibrium and how to relate these equilibria to the differential game literature

debt relief and adjustment effort in a multi period model abstract this paper shows that if the period following the granting of debt relief is taken into account debt relief increases adjustment effort investment irrespective of whether there is an initial debt overhang or not

the debt overhang and the disincentive to invest abstract this paper is an attempt to explore the debt overhang hypothesis by an empirical examination of the investment experience of 13 severely indebted countries it begins with a discussion of the disincentive effect of debt overhang which is linked to some aspects of the adjustment measures that these countries are undergoing viz devaluation and reduction in public sector deficits this is followed by empirical analysis which demonstrates that first in countries with a debt overhang external debt captures many of the effects of other explanatory variables that traditionally explain investment second through 1971 1991 the relationship between external debt and investment is consistently a negative one however the first half of the period has strong time influences that exercise a positive influence on investment in the second half of the period time effects turn negative too thus explaining the fall in investment levels observed after 1982

an interpretive examination of the development of cultural sensitivity in international business cultural sensitivity is assumed to be important in international business yet little empirical work explores how cultural sensitivity actually develops in depth interviews with buyers from the asian pacific rim were conducted and support was found for a four stage model of cross cultural sensitivity in which buyers move through the stages of romantic sojourner foreign worker skilled worker and partner this paper explores the development and evolution of cultural sensitivity as it interacts with trust and development of international business relationships

access based consumption the case of car sharing access based consumption defined as transactions that can be market mediated but where no transfer of ownership takes place is becoming increasingly popular yet it is not well theorized this study examines the nature of access as it contrasts to ownership and sharing specifically the consumer object consumer consumer and consumer marketer relationships six dimensions are identified to distinguish among the range of access based consumptionscapes temporality anonymity market mediation consumer involvement the type of accessed object and political consumerism access based consumption is examined in the context of car sharing via an interpretive study of zipcar consumers four outcomes of these dimensions in the context of car sharing are identified lack of identification varying significance of use and sign value negative reciprocity resulting in a big brother model of governance and a deterrence of brand community the implications of our findings for understanding the nature of exchange consumption and brand community are discussed

uncertainty economic reforms and private investment in the middle east and north africa during the 1980s and the 1990s private investment in the middle east and north africa mena has on average shown a decreasing or stagnant trend this contrasts with the situation of the asian economies where private investment has always been more dynamic in this paper it is empirically shown for a panel of 39 developing economies among which four mena countries that in addition to the traditional determinants of investment such as the growth anticipations and the real interest rate government policies explain mena s low investment rate insufficient structural reforms which have most of the time led to poor financial development and deficient trade openness have been a crucial factor for the deficit in private capital formation the economic uncertainties of the region have represented another factor of the firm s decisions not to invest these uncertainties have consisted of the external debt burden and various measures of volatility

large external debt and slow domestic growth a theoretical analysis abstract this paper analyzes the optimal rescheduling strategy of lenders whose claims on a country show a discount on the secondary markets the paper shows that lenders should proceed as follows they should split the debt into two components a performing and a nonperforming part they should act as if the debt amounted to the performing part and scale down how much money the borrower should service on that part only as a result it is shown that the efficient servicing of the debt crowds in investment the paper relates this result to the debt overhang argument according to which too large a nominal claim may reduce investment and the market value of the debt

approximating a cost of living index from demand functions a retrospect abstract this paper discusses several methods for approximating a cost of living index that are based on knowledge of the demand functions centered around a recently discovered article by malmquist it discusses the mean of over and undercompensation frisch s double expenditure method and some proposals of vartia

low investment and large ldc debt in the 1980s this paper aims at disentangling the correlation between ldc debt and investment in the 1980s the author shows that a large debt was not an unconditional predictor of low investment in the 1980s nor was investment abnormally low when compared to a financial autarky rate calculated in the text he does find however that the actual service of the debt crowded out investment for the rescheduling countries he shows that 1 percent of gdp paid abroad reduced domestic investment by 0 3 percent of gdp this is identical to the correlation between investment and foreign finance observed in the 1960s copyright 1993 by american economic association

debt relief investment and growth from 1989 to 2004 the donor community provided approximately 400 billion in debt relief to developing countries in an attempt to promote growth and reduce poverty using a sample of 118 developing countries this paper empirically assesses the impact of debt relief on growth via 1 resources made available for investment from reduced debt service payments and 2 improved incentives to invest from a reduced debt stock although the results show no general evidence of a growth effect from debt relief the study provides certain evidence that it promotes investment and thereby growth in countries not classified as hipcs

understanding the link between collaborative economy and sustainable behaviour an empirical investigation abstract the collaborative economy is growing at an exponential rate and the accommodation sector is especially affected the relevance of the phenomenon is linked with sustainable consumption that encourages resource efficiency waste reduction development of better products and surplus reutilization due to overproduction and overconsumption this paper aims at investigating the relationship between collaborative consumption and the adoption of sustainable practices from the users perspective after identifying the gaps existing in the literature different research approaches were integrated at first 4 focus groups were conducted to detect the main attributes and benefits attached to collaborative economy in tourism the personal values instrumental and terminal values relevant to p2p accommodation renting were identified through laddering technique as the propensity to put in place sustainable behaviour thereafter a structural model based on the framework of the theory of planned behaviour tpb constructs was set and tested to understand its consistency with the above values an ad hoc questionnaire was projected and administered online based on a sample of 384 respondents quantitative data were analysed through statistical and structural equation modeling software from an academic perspective the paper enhances the current knowledge in identifying the desired end states that users want to achieve by renting a p2p accommodation moreover it exploits and adapts the tpb to an emerging consumption model such as collaborative economy thus disclosing the relation between collaborative consumption and sustainable behaviour moreover the adaptation of tpb model to the newest context of collaborative economy expands the knowledge related to sustainable consumption from a managerial perspective it is necessary to emphasize the importance of defining a new business paradigm considering collaborative consumption to support environmental policy and encouraging sustainable behaviour

exact consumer s surplus and deadweight loss consumer s surplus is a widely used tool in applied welfare economics both economic theorists and cost benefit analysis often use consumer s surplus despite its somewhat dubious reputation the basic idea is to evaluate the value to a consumer or his willingness to pay for a change in price of a good from say pricep to pricep because price changes affect consumer welfare an evaluation of this effect is often a key input to public policy decisions yet consumer s surplus is probably the most controversial of widely used economic concepts both paul samuelson and ian little conclude that the economics profession would be better off without it it is my feeling of the situation that substantial agreement exists on the correct quantities to be measured the amount the consumer would pay or would need to be paid to be just as well off after the price change as he was before the price change the quantities correspond to john hicks compensating variation measures an alternative measure which takes ex post price change utility as the basis of comparison is hicks equivalent variation the controversy arises in the measurement of these quantities the usual measurement procedure is to use the area to the left of the marshallian market demand curve between two price levels jules dupuit originated this measure of welfare change and alfred marshall and hicks derived appropriate conditions for its use the primary condition for the area to the left of the demand curve to correspond to the compensating variation is to have constant marginal utility of income marshall gave this condition and if it holds the same quantity will be derived as the area to the left of the compensated hicksian demand curve this area to the left of the compensated demand curve is exactly what the compensating variation and equivalent variation measure thus the constant marginal utility of income is a sufficient condition for marshallian consumer s surplus to be equal to hicks consumer s surplus in this case arnold harberger s plea to use the welfare triangle as one half times the product of the price change times the quantity change to measure deadweight loss corresponds to the correct theoretical amount of welfare change in a recent paper robert willig derives bounds for the percentage difference between the correct measure of either the compensating or equivalent variation and the marshallian measure derived form the market demand curve his bounds which depend on the income elasticity of demand for the single good in the region of price change being considered as well as the proportion of the consumer s income spent on the good demonstrate that the marshallian consumer s surplus is often a good approximation to hicks consumer s surplus the fact that the proportion of the consumer s income spent matters as well as the income elasticity was first pointed out by harold hotelling willig contends that the approximation error will be less than the errors involved in estimating the demand curve thus he hopes to remove the need for apology that applied economists often need to give to theorists who remark on the inappropriateness of using marshallian consumer s surplus to measure welfare change however in this paper i show that for the case primarily considered by willig of a single price change which is also the situation in which consumer s surplus is often used in applied work no approximation is necessary professor of economics massachusetts institute of technology and research associate national bureau of economic research i would like to thank peter diamond erwin diewert daniel mcfadden robert merton robert solow hal varian joel yellin and the referees for help and comments research support from the national science foundation is acknowledged the reason that we still have two rather than one of samuelson s six measures of consumer s surplus arises from an index number problem of the correct basis for the welfare comparison i will give both measures but plan to concentrate on the compensating variation

compensating variation consumer s surplus and welfare the compensating variation was defined by j r hicks 1942 as the amount one would have to deduct from a person s income to make him just as well off after a change in prices and income as he had been in the initial situation if the compensating variation is positive the individual is better off under the new situation since the compensating variation furnishes a uniquely defined numerical cardinal indicator of welfare improvement it provides an implicit ranking of alternative prospective situations not only relative to the initial situation but also relative to each other in practice this appears to be how this and other tools of cost benefit analysis are actually used one is interested in knowing not only whether a particular bridge or a particular excise tax will lead to an improvement in welfare but which out of a set of alternative bridges or alternative tax systems will improve welfare the most 1 in this paper we analyze conditions under which the compensating variation can be validly used in this generalized sense these turn out to be precisely the same as conditions previously derived see our 1976 paper for the valid use of consumer s surplus as a welfare measure in our final section we analyze the problem of deriving the generalized equivalent and compensating variations either exactly or approximately from observable demand functions by means of generalizations of or alternatives to consumer s surplus

countervailing market responses to corporate co optation and the ideological recruitment of consumption communities from a conventional theoretical standpoint the corporatization of the organic food movement is an example of co optation co optation theory conceptualizes the commercial marketplace as an ideological force that assimilates the symbols and practices of a counterculture into dominant norms our alternative argument is that co optation can generate a countervailing market response that actively promotes the oppositional aspects of a counterculture attenuated by the process of commercial mainstreaming to develop this theoretical argument we analyze community supported agriculture which has emerged in response to the corporate co optation of the organic food movement we conclude by discussing how tacit political ideologies structure consumption communities

demythologizing consumption practices how consumers protect their field dependent identity investments from devaluing marketplace myths marketplace myths are commonly conceptualized as cultural resources that attract consumers to a consumption activity or brand this theoretical orientation is prone to overstating the extent to which consumers identity investments in a field of consumption are motivated by an associated marketplace myth we provide a theoretical corrective to this tendency by investigating consumers who have become vested in a commercially mythologized consumption field through an incremental process of building social connections and cultural capital for these consumers the prevailing marketplace myth is experienced as a trivialization of their aesthetic interests rather than as a source of identity value in response they employ demythologizing practices to insulate their acquired field dependent social and cultural capital from devaluation our findings advance theorizations concerning marketplace myths and consumer identity work and explicate the sociocultural forces that deter consumers from abandoning a consump

evidence of public spending crowding out from a panel of oecd countries the empirical relationship between government spending and private investment is examined using a panel of 14 oecd countries the evidence suggests the existence of a significant crowding in effect of private investment by public investment through the positive impact of infrastructure on private investment productivity moreover government consumption appears to crowd out private investment the implications of these results are of foremost importance when it comes to fiscal consolidation deficit reductions engineered through cuts in public investment could severely impinge on private capital accumulation and growth prospects

macroeconomic uncertainty and private investment abstract this paper provides empirical support for a link between macroeconomic uncertainty and private investment in developing countries cross section regressions with constructed measures of uncertainty confirm that for developing countries uncertainty is negatively correlated with private investment

from servicescape to consumptionscape a photo elicitation study of starbucks in the new china a servicescape can be viewed as the frozen potential of a consumptionscape which is unleashed when consumers twist the resources of its built environment for their own purposes in this paper we explore how young urban chinese consumers transform the iconic global brand starbucks into a consumptionscape through their enactment of personally meaningful experiences roles and identities in the setting we employ the qualitative research methodology of photo elicitation by having consumers record their experience in a starbucks in beijing through photography and later using these images as probes in a depth interview the implications for new global servicescapes in local markets are discussed

exploring the gap between consumers green rhetoric and purchasing behaviour why do consumers who profess to be concerned about the environment choose not to buy greener products more regularly or even at all this study explores how consumers perceptions towards green products consumers and consumption practices termed green perceptions contribute to our understanding of the discrepancy between green attitudes and behaviour this study identified several barriers to ethical consumption behaviour within a green consumption context three key themes emerged from the study it is too hard to be green green stigma and green reservations there is currently a perception based on a number of factors that it is too hard to be green which creates a barrier to purchasing green products furthermore some consumers were reluctant or resistant to participate in green consumption practices due to their unfavourable perceptions of green consumers and green messages this article suggests that green perceptions may influence consumers intention to purchase green products accordingly it discusses the implications and suggests avenues for future research

modeling private investment in egypt abstract this paper presents an empirical model of private investment that takes into account certain features of a developing economy such as the oligopolistic structure of markets putty clay technology the inelastic supply of non traded capital goods and financial repression the model is tested on egyptian data using error correction and cointegration the results for egypt indicate that at the macroeconomic level private investment depends on mark ups internal financing demand and the cost of investment goods defined not as the interest rate but as the outcome of the interaction of supply and demand in the market for capital goods the effects of government policy on private investment are mixed with some evidence of crowding out in credit markets and of crowding in as a result of government investment in infrastructure

consumer s surplus without apology the purpose of this paper is to settle the controversy surrounding consumer s surplus and by so doing to validate its use as a tool of welfare economics i will show that observed consumer s surplus can be rigorously utilized to estimate the unobservable compensating and equivalent variations the correct theoretical measures of the welfare impact of changes in prices and income on an individual i derive precise upper and lower bounds on the percentage errors of approximating the compensating and equivalent variations with consumer s surplus these bounds can be explicitly calculated from observable demand data and it is clear that in most applications the error of approximation will be very small in fact the error will often be overshadowed by the errors involved in estimating the demand curve the results in no way depend upon arguments about the constancy of the marginal utility of income consequently this paper supplies specific empirical criteria which can replace the apologetic caveats frequently employed by those who presently apply consumer s surplus moreover the results imply that consumer s surplus is usually a very good approximation to the appropriate welfare measures to preview below i establish the validity of these rules of thumb for a

determinants of private investment in developing countries this paper examines a modified version of the flexible accelerator theory of investment with particular reference to developing countries the empirical results for five countries tend to confirm that government investment the change in bank credit to the private sector and capital inflow to the private sector play important roles in determining private investment the contributory effect and the crowding out effect of government investment are assessed within the context of a recursive model

international and domestic collateral constraints in a model of emerging market crises abstract we build a model of emerging markets crises which features two types of collateral constraints firms in a domestic economy have limited borrowing capacity from international investors they also have limited borrowing capacity with respect to each other we study how the presence and changes in these collateral constraints affect financial and real variables a binding international constraint in the aggregate leads to a sharp rise in interest rates and fire sales of domestic assets while limited domestic collateral can lead to wasted international collateral these two collateral constraints can interact in important ways the first is disintermediation a fire sale of domestic assets causes banks to fail in their function of reallocating resources across the economy leading to wasted international collateral the second is a dynamic effect we show that firms in an economy with limited domestic collateral and a binding international collateral constraint will not adequately precaution against adverse shocks increasing the severity of these shocks

financing vs forgiving a debt overhang abstract this paper examines the tradeoffs facing creditors of a country whose debt is large enough that the country cannot attract voluntary new lending if the country is unable to meet its debt service requirements out of current income the creditors have two choices they can finance the country lending at an expected loss in the hope that the country will eventually be able to repay its debt after all or they can forgive reducing the debt level to one that the country can repay the post 1983 debt strategy of the imf and the us has relied on financing but many current calls for debt reform call for forgiveness instead the paper shows that the choice between financing and forgiveness represents a tradeoff financing gives the creditors an option value if the country turns out to do relatively well creditors will not have written down their claims unnecessarily however the burden of debt distorts the country s incentives since the benefits of good performance go largely to creditors rather than itself the paper also shows that the tradeoff itself can be improved if both financing and forgiveness are made contingent on states of nature that the country cannot affect such as oil prices world interest rates etc

financial development and economic growth views and agenda this critique argues that the preponderance of theoretical reasoning and empirical evidence suggests a positive first order relationship between financial development and economic growth the body of work would push even most skeptics toward the belief that the development of financial markets and institutions is a critical and inextricable part of the growth process and away from the view that the financial system is an inconsequential sideshow responding passively to economic growth many gaps remain however and the paper highlights areas in acute need of additional research

volatility and investment interpreting evidence from developing countries we uncover a significant negative correlation between various volatility measures and private investment in developing countries even when adding the standard control variables no such correlation is uncovered when the investment measure is the sum of private and public investment spending indeed public investment spending is positively correlated with some ineasures of volatility these findings suggest that the detrimental impact of volatility on investment may be easier to detect using disaggregated data we provide several possible interpretations for our findings nonlinearities in preferences or budget constraints can cause volatility to have first order negative effects on private investment
