the welfare effects of energy price changes due to energy market reform in mexico abstract despite being a large energy producer and exporter mexico may soon become a net total energy importer due to a decline in oil reserves and increasing domestic consumption to increase efficiency in the energy market mexican authorities approved a constitutional amendment aiming to open the state run energy markets to competition in 2013 the reform is expected to raise efficiency and to lower energy prices in the long run however it will take some time for the new institutional arrangements to settle and the reform objectives to materialize the removal of subsidies which is expected to take place after the reform will also raise prices particularly in the short run in this paper we analyze the effect of likely energy price changes due to energy market reform on household consumption and welfare in different income groups we estimate the quaids model using the nonlinear sure method and the mexican household budget surveys for the period 2002 2012 to obtain elasticities the results show great heterogeneity in elasticities across energy types and income groups specifically energy demand is elastic with respect to income but changes in prices have mixed effects among energy types the welfare effect of the price changes on low income households will be 9 times stronger than that on the mid income households and 18 times on and the high income households this warrants a compensation package to make the reform socially acceptable

precautionary saving and endogenous labor supply with and without intertemporal expected utility we analyze precautionary saving behavior in a framework with labor and nonlabor income risks an endogenous supply of labor and a representation of preferences that disentangles attitudes towards risk attitudes towards intertemporal substitution and ordinal preferences for consumption and leisure this preference structure allows us to disentangle and to describe in an intuitive way the different forces that determine precautionary saving in the small and in the large

wealth distribution in life cycle economies abstract this paper compares the age wealth distribution produced in life cycle economies to the corresponding distribution in the us economy the idea is to calibrate the model economies to match features of the us earnings distribution and then examine the wealth distribution implications of the model economies the findings are that the calibrated model economies with earnings and lifetime uncertainty can replicate measures of both aggregate wealth and transfer wealth in the us furthermore the model economies produce the us wealth gini and a significant fraction of the wealth inequality within age groups however the model economies produce less than half the fraction of wealth held by the top 1 percent of us households

second best pricing and cooperation this article studies pricing for natural monopolies by using a cooperative game of joint production outputs are allocated by a price system we introduce the concept of the second best core which is a subset of the set of zero profit second best pareto optimal prices prices are such that no group of consumers subsidizes the purchase of another group we consider the relations among the second best core and sustainability supportability and natural monopoly for specific preferences and technology we demonstrate the existence of the second best core we design a market mechanism for franchise allocation which achieves second best pricing without price regulation

second best taxation as a game second best theory usually lies in the realm of normative analysis it focuses attention on the best solutions which still can be obtained in problems where constraints of various natures forbid the attainment of first best pareto optimal situations its central concern is the characterization of such second best solutions and a large part of the literature concentrates on the optimal design of taxes or of policies of public firms taking a second best problem we try in this paper to shift the emphasis from normative to positive considerations the solution we are interested in is not optimal with respect to some a priori given social welfare function embodying justice objectives but it is supposed to reflect the power of the different agents in a negotiation process clearly the conceptual tools required for such an analysis are to be found in game theory and it is actually a game theoretical approach that we follow here the model we are looking at is presented in section ii it formalizes one of the simplest second best problems that can be imagined we have a twogood economy with one private good and one public good agents have different wealth in private good and the public good is financed through a wealth tax this latter fiscal system is clearly not flexible enough to adjust contributions with marginal willingnesses to pay so that we actually face a second best situation there is one decision variable in the society the tax rate which determines the public good production about which the agents have conflicting desires to this problem we associate a game which provides a precise framework for the analysis of the power of the agents the positive outcomes of the negotiation process are supposed to belong to the core of this game sections iii and iv concentrate on the analysis of the core the results strongly contrast with those obtained in the classical studies of the core of 67 0022 053 l 81 040067 25 02 00 o

energy demand in the transportation sector of mexico abstract this paper report results of an analysis of the demand for energy in the mexican transport sectors focusing on the railroad air transport and motor vehicle modes the approach is an econometric one with emphasis placed on the structure for each mode for two of the modes a two stage approach is employed where in the first stage demands for services from the particular mode are modeled and in the second stage demand is treated as a derived demand from these transport services for the motor vehicle mode gasoline demand is considered as the product of gasoline consumption per vehicle times the total number of vehicles and then these components are related to economic and structural variables diesel demand of motor vehicles is modeled in a more reduced from approach the principal finding is that changes in income play a more important role in affecting energy demand than do changes in energy prices especially in the railroad and air transport sectors for the gasoline and diesel fuel demand in the monitor vehicle sector however price is of substantial importance

spatial competition and the core models of spatial competition have proven useful in describing differentiated product markets a serious problem is the nonexistence of nash equilibria this problem is resolved by modelling the price formation process using the core the equilibrium is the outcome of a two stage process in the first stage two firms choose locations simultaneously the second stage has prices determined by an allocation in the core of a cooperative subgame allowing for coalitions of buyers and sellers these prices approach the competitive level as the distance between the firms goes to zero thus capturing the essence of duopoly rivalry this abstract was borrowed from another version of this item

projecting the energy pathway using a methodological sequence the case of mexico abstract the relationship between primary energy and economic development tends to be positive however it is a complex relationship for emerging economies we use the energy pathway ep method to 1 examine this relationship 2 introduce its behavioural taxonomy and 3 propose a hybrid methodological sequence that allows to examine the historical context and to forecast the ep we apply our methodology to the mexican case an emerging economy that has had both energy intensive and energy productivity periods and changes in its development model the study was conducted by using data of a 52 year old path and explored the path may have from 2018 onwards our results are as follows first the pathway shows nine behavioural possibilities second we found that the mexican ep responds to structural changes we conclude that for the years following 2018 mexico s path will have a disturbance the main objective will be to avoid unwanted behaviour the key is to improve the relationships among the government the private sector and international agreements in order to continue the sequence of the theory on the relations between energy and development more studies are needed under a systematic analytical framework applied to both other countries and comparative studies

the impact of the correlation between health expenditure and survival probability on the demand for insurance abstract this paper studies the effects of health shocks on the demand for health insurance and annuities along with precautionary saving in a dynamic life cycle model i argue that when the health shock can simultaneously increase health expenses and reduce longevity rational agents would neither fully insure their uncertain health expenses nor fully annuitize their wealth because the correlation between health expenses and longevity provides a self insurance channel for both uncertainties that is when the agent is hit by a health shock which simultaneously increases health expenses and reduces longevity she can use the resources originally saved for consumption in the reduced period of life to pay for the increased health expenses since the two uncertainties partially offset each other the precautionary saving generated in the model should be smaller than in a standard model without the correlation between health expenses and longevity in a quantitative life cycle model calibrated using the medical expenditure panel survey dataset i find that the health expenses are highly correlated with the survival probabilities and this correlation significantly reduces the demand for actuarially fair health insurance while its impact on the demand for annuities and precautionary saving is relatively small

u s tax policy and health insurance demand can a regressive policy improve welfare abstract the u s tax policy on health insurance is regressive because it subsidizes only those offered group insurance through their employers who also tend to have a relatively high income moreover the subsidy takes the form of deductions from the progressive income tax system giving high income earners a larger subsidy to understand the effect of the policy we construct a dynamic general equilibrium model with heterogenous agents and an endogenous demand for health insurance a complete removal of the subsidy may lead to a partial collapse of the group insurance market reduce the insurance coverage and deteriorate welfare there is however room for improving the coverage and welfare by extending a refundable credit to the individual insurance market

bargaining in a network of buyers and sellers abstract we analyze bargaining between buyers and sellers who are connected by an exogenously given network players can make repeated alternating public offers that may be accepted by any of the responders linked to each specific proposer our purpose is to find the conditions of the network which drive the price distribution in equilibrium this paper uses graph theory tools to provide necessary and sufficient conditions regarding the architecture of networks for the subgame perfect equilibrium of the bargaining game to coincide with the walrasian outcome

uncertain medical expenses and precautionary saving near the end of the life cycle this paper introduces a dynamic structural model of household consumption decisions in which elderly families consider the effects of uncertain future medical expenses when deciding current levels of consumption the model with uncertain medical expenses implies a potentially important role for precautionary saving incentives to explain slow rates of dissaving among elderly americans during retirement rather than just simulating the stochastic dynamic model preference parameters are estimated using panel data on health wealth and expenditures for retired families the health uncertainty model predicts consumption levels closer to observed expenditures than a life cycle model with uncertain longevity however elderly families typically dissave their financial assets more slowly than even the baseline health uncertainty model predicts is optimal

an evaluation of the impact of reducing energy subsidies on living expenses of households abstract a policy of subsidizing energy has been pursued in the islamic republic of iran to help the poor and to utilize the relative advantages of the country but it has been realized that energy subsidy has led to market distortion and welfare loss hence elimination of energy subsidy is considered as a crucial matter changes in energy policy are hindered by the uncertainty on the impact of reducing energy subsidy on the living expenses of population in the present article the distribution of resources through energy subsidy is evaluated and the direct and indirect effect of eliminating energy subsidies on the living expenses is estimated with the help of an analytical tool that has been developed it is then concluded that additional financial resources obtained from reduction of energy subsidies could be allocated for compensating the decrease in purchasing power of households the results of analysis reveal that more egalitarian distribution of resources and helping the poor could be achieved through implementation of a progressive policy of social security that is supported by financial resources available from elimination of energy subsidies

a theoretical foundation for the undercut proof equilibrium abstract this paper develops a theoretical foundation for the undercut proof equilibrium see shy 1996 shy 2002 morgan and shy 2015 in a general spatial setting the set of undercut proof prices is equivalent to the core of a non transferable utility coalitional game played on the set of outcomes that are feasible in bertrand competition the result depends critically on two conditions first firms must have unlimited capacity and constant marginal costs second the goods produced by firms must only be differentiated by the spatial characteristics of the market an application to network markets shows how the undercut proof equilibrium can be used to describe stable price dispersion and persistent performance differences

an evaluation of the welfare effects of reducing energy subsides in iran abstract energy prices in iran have traditionally been heavily subsidized by the government and as a result energy consumption per capita in iran is close to the european union level the welfare effects of efforts to raise energy prices closer to world levels are examined in this paper reform of energy prices is an important element of the economic reform plan 2010 2014 for iran we first analyze the relationship between energy consumption energy and non energy prices by estimating the household expenditure function the results show that a higher energy prices will decrease energy consumption by iranian households second we evaluate the impact of a rise of energy prices on the household welfare by measuring the compensating variation cv in five steps with a compensating payment the results show that iranian household welfare will increase with a 100 or 200 rise in energy prices if the government pays 20 30 or 50 of the 20 billion income resulting from removing energy subsidies while in contrast iranian household welfare will decrease with a 400 and 500 rise in energy prices if the government payment is 20 or 30 of 20 billion income

production and high energy prices a case of some pan pacific countries abstract to explore the relationship between price of energy energy consumption and output this paper suggests a simultaneous equation system using time series data for five pan pacific countries canada japan korea the philippines and the usa and applying the two stage least squares method the above system of equations is estimated for each of the five countries short run gdp elasticity with respect to energy is nearly the same 0 3 for all four industrialized countries short run price elasticity of energy demand is between 0 20 and 0 08 for the four industrialized economies and 0 37 for the philippines

consumption during retirement the missing link in the life cycle this study presents the first evidence on the relation of consumption to lifetime wealth based on data from the 1973 and 1975 retirement history survey that have been linked to social security earnings records nearly 500 white married fully retired couples ages 62 69 form the basis of the analysis on average their consumption early in retirement exceeds by 14 percent the income that their financial pension and social security wealth can generate this implies that their saving both private and through social security is insufficient to sustain consumption throughout the rest of their lives additional evidence based on changes in spending between 1973 and 1975 shows that these households respond by reducing their real consumption at a rate sufficient to generate positive changes in net financial worth within a few years after retirement these two pieces of evidence can be rationalized by a rate of time preference much higher than the interest rate coupled with either a bequest motive or uncertainty about the length of life they also imply that even when combined with private pensions and savings social security in the united states today does not enable most recipients to maintain their living standard at the levels they enjoyed before they retired this abstract was borrowed from another version of this item

the impact of technical change on the aggregate production function this study endeavours to look at both disembodied technical progress and embodied technical progress in the capital stock and in the labour force in the united states over the period 1947 80 the results suggest that disembodied technical progress has been about 3 per year embodied technical progress in the capital stock is approximately 3 4 per year and educational attainment significantly enhances labour productivity finally when the issue of structural stability of the underlying production relationship is addressed the period 1971 80 gives rise to some inconsistency

health care reform or more affordable health care this article investigates the impact on the u s economy of making health care more affordable we compare health care cost reductions with the patient protection and affordable care act aca using a rich life cycle general equilibrium model with heterogeneous agents we evaluate a wide range of cost reductions ranging from 0 64 realistic and feasible to 29 5 equivalence with oecd our results show that the aca is more effective in reducing uninsured population than all cost reductions considered this result holds throughout the life cycle and for the most fragile part of the population the poorest the less educated and those with bad health realistic and feasible cost reductions are less welfare improving than the aca the increase of welfare induced by the reform is around 7 8 times higher than the increase provided by cost reductions besides the poorer are more benefited than the richer after the reform while the opposite occurs after cost reductions finally to obtain the same welfare increase of the aca medical costs have to decrease by 5 21 a very hard task these results provide support for the aca against opponents who might present cost reductions as alternatives

life cycle effects of health risk abstract health status affects individuals labor supply asset accumulation and welfare through four main channels productivity medical expenditures time endowments and survival probabilities using a life cycle model calibrated to the u s for different education groups i evaluate the relative importance of each channel and quantify their interactions the productivity and time endowment channels dominate in importance and the risks implied by them contribute significantly to income inequality and precautionary savings health effects are larger for the non college than college educated and account to a large extent for the lower labor supply and higher reliance on government transfers of the non college group

a theory of buyer seller networks this paper introduces a new model of exchange networks rather than markets of buyers and sellers it begins with the empirically motivated premise that a buyer and seller must have a relationship a link to exchange goods networks buyers sellers and the pattern of links connecting them are common exchange environments this paper develops a methodology to study network structures and explains why agents may form networks in a model that captures characteristics of a variety of industries the paper shows that buyers and sellers acting strategically in their own self interests can form the network structures that maximize overall welfare

medical care costs how much welfare loss hardly a week goes by without a front page newspaper article on rising health care costs and the uninsured in this article i focus mainly on costs arguing that the issue has been somewhat misconceived while the level of medical care spending in the u s is a cause for concern the welfare losses associated with rises in that level of spending may not be as large as the public rhetoric can make them seem in fact cost containment may not be as urgent as is widely supposed and some proposed cost containment policies may result in welfare losses for the insured and even increase the number of uninsured

is consumption growth consistent with intertemporal optimization evidence from the consumer expenditure survey in this paper we show that some of the predictions of models of consumer intertemporal optimization are in line with the patterns of nondurable expenditure observed in u s household level data we propose a flexible specification of preferences that allows multiple commodities and yields empirically tractable equations we estimate preference parameters using the only u s micro data set with complete consumption information we show that previous rejections can be explained by the simplifying assumptions made in previous studies we also show that results obtained using good consumption or aggregate data can be misleading

priority setting in health care and higher order degree change in risk this paper examines how priority setting in health care expenditures is influenced by the presence of uncertainty about the severity of the illness and the effectiveness of medical treatment we provide necessary and sufficient conditions on social preferences under which a social planner will allocate more health care resources to populations at higher risk changes in risk are defined by the concept of stochastic dominance up to order n the shape of the social utility function and an equity weighting function are used to model the inequality aversion of the social planner we show that for higher order risk changes the usual conditions on preferences such as prudence or relative risk aversion are not necessarily required to prioritise health care when there are different levels of uncertainty associated with otherwise similar patient groups

health insurance reform the impact of a medicare buy in abstract the steady state general equilibrium and welfare consequences of a medicare buy in program optional for those aged 55 64 is evaluated in a calibrated life cycle economy with incomplete markets incomplete markets and adverse selection create a potential welfare improving role for health insurance reform we find that adverse selection eliminates any market for a medicare buy in if it is offered as an unsubsidized option to individual private health insurance the subsidy needed to bring the number of uninsured to less than 5 percent of the target population could be financed by an increase in the labor income tax rate of just 0 03 0 18 percent depending on how the program is implemented

the role of asset testing in public health insurance reform abstract starting slowly with the 1996 welfare reform act and culminating in the 2010 affordable care act means tested public health insurance eligibility expanded to include adults in low income families regardless of their asset holdings this paper quantifies the effects of these eligibility expansions within the context of the 2010 affordable care act i construct a dynamic stochastic general equilibrium model with indivisible labor supply expanded to include an endogenous household choice of health insurance coverage and calibrate it to u s data i establish that changes in the distribution of labor and welfare associated with removal of asset testing are driven by exit of high productivity and high wealth households from the labor market i then expand my analysis to the 2010 affordable care act to demonstrate that removal of asset testing is critical to the obtained results even when combined with other provisions of the act finally i find that a simple asset test for eligibility of health insurance transfers undoes the distortion to the household labor supply decision among high productivity types these results are robust to the introduction of employer premium contributions an independent health insurance market and idiosyncratic shocks to eligibility for employment based health insurance

a superior measure of consumption from the panel study of income dynamics abstract this paper provides a simple technique for assigning a measure of total consumption to households in the panel study of income dynamics psid using regressions from the consumer expenditure surveys of 1972 1973 and 1983 linear predictions of total consumption are estimated which are stable over time and explain up to 78 percent of the total variance in consumption

estimates of energy and non energy elasticities in selected asian manufacturing sectors policy implications abstract this paper presents the results of a study of the demand elasticities for energy and non energy inputs in the food processing and textile industries in bangladesh the philippines and thailand estimates of substitution elasticities in production were derived by fitting data to a translog cost function for the period 1970 1980 for bangladesh 1970 1978 for the philippines and 1974 1977 for thailand the results varied according to the industries studied and across countries they were compared with those of several developing and industrialized countries and substitutability among inputs was found to be greater in the manufacturing sector of the developing countries studies than in those of industrialized countries the generally high elasticities between labour and energy have implications for relative input pricing and use in developing countries

the effects of health insurance and self insurance on retirement behavior this paper provides an empirical analysis of the effects of employer provided health insurance medicare and social security on retirement behavior using data from the health and retirement study we estimate a dynamic programming model of retirement that accounts for both saving and uncertain medical expenses our results suggest that medicare is important for understanding retirement behavior and that uncertainty and saving are both important for understanding the labor supply responses to medicare half the value placed by a typical worker on his employer provided health insurance is the value of reduced medical expense risk raising the medicare eligibility age from 65 to 67 leads individuals to work an additional 0 074 years over ages 60 69 in comparison eliminating 2 years worth of social security benefits increases years of work by 0 076 years

intertemporal substitution in labor supply evidence from micro data the sensitivity of the supply of labor to intertemporal variation in the wage is an important issue in macroeconomics the analysis of social security and pensions and the study of life cycle patterns of work this paper explores two approaches to the measurement of intertemporal substitution that have appeared in the literature the first approach is to use consumption to control for wealth and unobserved expectations about future wages in the labor supply equation the second approach is to estimate a first difference equation for hours in which labor supply from the previous period serves as a control for wealth and wage expectations the results indicate that intertemporal substitution elasticity for married men is positive but small

retirement wealth and lifetime earnings this article argues that a satisfactory theory of wealth inequality should account not only for the marginal distribution of wealth but also for the joint distribution of wealth and earnings the article describes the joint distribution of retirement wealth and lifetime earnings in the panel study of income dynamics it then evaluates the ability of a stochastic life cycle model to account for key features of this distribution the life cycle model fails to account for three key features of the data 1 the correlation between lifetime earnings and retirement wealth is too high 2 the wealth gaps between earnings rich and earnings poor households are too large 3 wealth inequality among households with similar lifetime earnings is too small models in which households differ in rates of return or time preferences account much better for the joint distribution of retirement wealth and lifetime earnings

solution of the hotelling s game in secure strategies abstract we show that the price setting subgame in the classic hotelling s model 1929 with the linear transport costs has the unique equilibrium solution for all location pairs under the assumption that duopolists secure themselves against being driven out of the market by undercutting in contrast to the modified zero conjectural variation approach of eaton and lipsey 1978 we assume that the players consider the threat of pressing out of the market as a real possibility we employ the concept of equilibrium in secure strategies einss as the generalization of the nash equilibrium the einss coincides with the nash equilibrium when nash equilibrium exists and postulates the incentive of players to maximize their profit under the condition of security against the actions of other players

the life cycle model of consumption and saving a central implication of life cycle models is that agents smooth consumption we review the empirical evidence on smoothing at frequencies from within the year up to across a lifetime we find that life cycle models particular those which incorporate realistic features of markets and goods have more empirical successes than failures we also show that some apparent deviations from theoretical predictions imply very small welfare losses for agents finally we emphasize that the coherence of life cycle models imposes an important discipline when incorporating new features into models

technology growth and expenditure growth in health care in the united states health care technology has contributed to rising survival rates yet health care spending relative to gdp has also grown more rapidly than in any other country we develop a model of patient demand and supplier behavior to explain these parallel trends in technology growth and cost growth we show that health care productivity depends on the heterogeneity of treatment effects across patients the shape of the health production function and the cost structure of procedures such as mris with high fixed costs and low marginal costs the model implies a typology of medical technology productivity i highly cost effective home run innovations with little chance of overuse such as anti retroviral therapy for hiv ii treatments highly effective for some but not for all e g stents and iii gray area treatments with uncertain clinical value such as icu days among chronically ill patients not surprisingly countries adopting category i and effective category ii treatments gain the greatest health improvements while countries adopting ineffective category ii and category iii treatments experience the most rapid cost growth ultimately economic and political resistance in the u s to ever rising tax rates will slow cost growth with uncertain effects on technology growth

the effects of health wealth and wages on labour supply and retirement behaviour this paper estimates a life cycle model of labour supply retirement and savings behaviour in which future health status and wages are uncertain individuals face a fixed cost of work and cannot borrow against future labour pension or social security income the method of simulated moments is used to match the life cycle profiles of labour force participation hours worked and assets that are estimated from the data to those that are generated by the model the model establishes that the tax structure of the social security system and pensions are key determinants of the high observed job exit rates at ages 62 and 65 removing the tax wedge embedded in the social security earnings test for individuals aged 65 and older would delay job exit by almost one year by contrast social security benefit levels health and borrowing constraints are less important determinants of job exit at older ages for example reducing social security benefits by 20 would cause workers to delay exit from the labour force by only three months

optimal mandates and the welfare cost of asymmetric information evidence from the u k annuity market much of the extensive empirical literature on insurance markets has focused on whether adverse selection can be detected once detected however there has been little attempt to quantify its welfare cost or to assess whether and what potential government interventions may reduce these costs to do so we develop a model of annuity contract choice and estimate it using data from the u k annuity market the model allows for private information about mortality risk as well as heterogeneity in preferences over different contract options we focus on the choice of length of guarantee among individuals who are required to buy annuities the results suggest that asymmetric information along the guarantee margin reduces welfare relative to a first best symmetric information benchmark by about 127 million per year or about 2 percent of annuitized wealth we also find that by requiring that individuals choose the longest guarantee period allowed mandates could achieve the first best allocation however we estimate that other mandated guarantee lengths would have detrimental effects on welfare since determining the optimal mandate is empirically difficult our findings suggest that achieving welfare gains through mandatory social insurance may be harder in practice than simple theory may suggest

the value of life and the rise in health spending over the past half century americans spent a rising share of total economic resources on health and enjoyed substantially longer lives as a result debate on health policy often focuses on limiting the growth of health spending we investigate an issue central to this debate is the growth of health spending a rational response to changing economic conditions notably the growth of income per person we develop a model based on standard economic assumptions and argue that this is indeed the case standard preferences of the kind used widely in economics to study consumption asset pricing and labor supply imply that health spending is a superior good with an income elasticity well above one as people get richer and consumption rises the marginal utility of consumption falls rapidly spending on health to extend life allows individuals to purchase additional periods of utility the marginal utility of life extension does not decline as a result the optimal composition of total spending shifts toward health and the health share grows along with income in projections based on the quantitative analysis of our model the optimal health share of spending seems likely to exceed 30 percent by the middle of the century

what accounts for the variation in retirement wealth among u s households even among households with similar socioeconomic characteristics saving and wealth vary considerably life cycle models attribute this variation to differences in time preference rates risk tolerance exposure to uncertainty relative tastes for work and leisure at advanced ages and income replacement rates these factors have testable implications concerning the relation between accumulated wealth and the shape of the consumption profile using the panel study of income dynamics and the consumer expenditure survey we find little support for these implications the data are instead consistent with rule of thumb mental accounting or hyperbolic discounting theories of wealth accumulation jel di d91 e21

saving response to unemployment of a sibling abstract standard theoretical models of household saving behavior do not typically assume that household perceptions of the world change in response to observed events in light of the potential importance of such perception changes e g after a financial crisis this paper considers the hypothesis that a household s saving rate rises through informal learning after a sibling direct or in law has been unemployed the empirical results in this paper are consistent with the learning hypothesis with coefficients estimated by the instrumental variable iv method implying that a household s saving rate increases by 2 3 percentage points if a sibling has been unemployed

uncertain health and survival effects on end of life consumption this article analyzes the impact of health and survival uncertainty on the saving and consumption decisions of retirees a dynamic programming approach is used to model the household s planning problem the utility parameters are estimated using panel data we find that a fall into poor health raises the marginal utility from consumption simulations are used to indicate the effects of falling into poor health and loss of spouse they reveal a large transfer from the healthy to the sick partner and a strong dependence of saving on the survivor benefits suggesting that concern about the surviving spouse is an important motive for saving

the paper work of medicine understanding international medical costs this paper draws on international evidence on medical spending to examine what the united states can learn about making its healthcare system more efficient we focus primarily on understanding contemporaneous differences in the level of spending generally from the 2000s medical spending differs across countries either because the price of services differs for example a coronary bypass surgery operation may cost more in the united states than in other countries or because people receive more services in some countries than in others for example more bypass surgery operations within the price category there are two further issues whether factors earn different returns across countries and whether more clinical or administrative personnel are required to deliver the same care in different countries we first present the results of a decomposition of healthcare spending along these lines in the united states and in canada we then delve into each component in more detail administrative costs factor prices and the provision of care received bringing in a broader range of international evidence when possible finally we touch upon the organization of primary and chronic disease care and discuss possible gains in that area

a quick and easy method for estimating switching costs abstract i develop and test a method for a quick and easy calculation of consumer switching costs among brands in a given industry the theory developed and tested here maps observed brands prices and market shares onto the switching costs which deter a consumer of a specific brand from switching to any other competing brand then i demonstrate how users switching costs can be directly calculated in two different industries a the israeli cellular phone market and b the finnish market for bank deposits this calculation method can be used to calculate switching costs in a wide variety of other industries such as airlines health services computers software telecommunications and more

an evaluation of the economic effects of higher energy prices in mexico abstract the analysis of this study examines the impact of an increase in the prices of gasoline and electricity on the mexican economy the analytical approach used consists of a general equilibrium model composed of 13 producing sectors 14 consuming sectors 4 household categories classified by income and one government the effects of the recently implemented increase in the price of gasoline and electricity of 26 2 on prices and quantities are examined the results are revealing for example the consequences of an increase in the prices of gasoline and electricity would be a decrease in output by all producing sectors of about 0 31 a fall in the consumption of goods and services by about 0 56 a reduction in total utility by 1 29 and higher revenue for the government of 0 31 when subjected to a sensitivity analysis the results are reasonably robust with regard to the assumption of the values of the substitution elasticities

uncertain lifetime consumption and dissaving in retirement this paper asks whether the continued accumulation or mild dissaving observed among the retired can be explained by uncertain lifetime in the absence of annuities after an initial period influenced by borrowing constraints under constant relative risk aversion uncertain lifetime depresses consumption by a proportion increasing with age if the elasticity of intertemporal substitution in consumption is small illustrative computations based on actual income and survival data show that plausible elasticities are sufficiently small to give this effect the reduction in consumption is large enough to explain much of the lack of decumulation by the elderly

the retirement savings puzzle reviewed the role of housing and bequests the so called retirement savings puzzle is a phenomenon by which contrary to what the standard life cycle model predicts households do not run down their wealth significantly during retirement in this review paper we survey the literature on the retirement savings puzzle and we connect it with the literature on housing equity during retirement to establish a link between these two streams of literature we use as a framework the work of nakajima and telyukova 2013a home equity in retirement ucsd working paper and nakajima and telyukova 2017 reverse mortgage loans a quantitative analysis journal of finance 72 911 950 who find that home ownership interacts with factors that explain the retirement savings puzzle notably with the bequest motive we complement the results by nakajima and telyukova by relating them to the literature on altruistic bequests strategic bequests and housing as a commitment device all of which give further insights on the connection between home ownership and bequests we complement our review of the literature with descriptive evidence using the netherlands as a case study

gaining ground poverty in the postwar united states official measures of poverty in the united states are compiled by the bureau of the census by comparing a household s income level to a prespecified threshold from a theoretical perspective it is more appropriate to evaluate the level of poverty using a consumption based measure of household welfare in this paper i evaluate the level of poverty using expenditure data from the consumer expenditure survey i find that consumption based poverty rates are much lower than those based on income the trend in the poverty rate in the united states is sensitive to the price index and equivalence scales used to adjust the poverty thresholds

identifying the main emitters of carbon dioxide in mexico a multi sectoral study in this paper input output and sam based multiplier models are formulated to identify the main emitters of direct indirect and induced carbon dioxide co2 for the mexican economy the models are based on a social accounting matrix for mexico with disaggre gated household income and consumption patterns according to the official poverty line the results show that the final users of the inputs that embody high levels of co2 emissions are the next five sectors 1 construction 2 electricity gas and water supply 3 inland transport 4 food beverages and tobacco and 5 coke refined petroleum and nuclear fuel the findings suggest that the implementation of a carbon tax could damage poor families since these families generate high direct indirect and induced co2 emissions per unit of income as a consequence of their consumption patterns of fuels and the products that embody high co2 emissions levels for example agriculture hunting forestry and fishing

efficient spatial competition abstract game theoretic models of spatial competition usually assume that firms set prices after their choices of locations rather than make this assumption this paper uses the core to model the competition between the firms two conditions are shown to be sufficient for efficient spatial competition the first is that the firms location choices satisfy a no externalities condition the second is that the second stage game satisfy a separable value condition namely that the value gains from trade can be created on a buyer by buyer basis this approach yields two further benefits first efficient location can be stable in situations with arbitrary distributions of buyers arbitrary willingness to pay functions and completely general location spaces second efficiency in location games can be shown to be related to the second welfare theorem

precautionary saving in the small and in the large the theory of precautionary saving is shown to be isomorphic to the arrow pratt theory of risk aversion making possible the application of a large body of knowledge about risk aversion to precautionary saving and more generally to the theory of optimal choice under risk in particular a measure of the strength of the precautionary saving motive analogous to the arrow pratt measure of risk aversion is used to establish a number of new propositions about precautionary saving and to give a new interpretation of the dreze modigliani substitution effect copyright 1990 by the econometric society
