changing the way the elderly live evidence from the home health care market in the united states abstract i examine how decreases in government coverage of home health care visits to the elderly in the united states have affected their living arrangements specifically i exploit geographic variation in the medicare home health care reimbursement rate that arose as a result of legislation passed in 1997 and i identify its impact on the living arrangements of older medicare beneficiaries i find that less generous reimbursement policies lead to a greater fraction of elderly giving up independent living baseline model estimates suggest that a decline in reimbursement of one visit per user leads to a 0 98 increase in the fraction of elderly medicare beneficiaries living in shared living arrangements that is living with somebody else rather than alone or with only the spouse this estimate implies that a decline in reimbursement of 5 1 visits per medicare beneficiary increases the fraction of elderly that live in shared living arrangements by 1 12 percentage points such an increase is consistent with the time series increase in the fraction of elderly that live in shared living arrangements between 1997 and 2000

long term care insurance informal care and medical expenditures abstract this paper provides empirical evidence on the short run impact of government subsidies of long term care we apply a regression discontinuity design using administrative data from south korea to estimate the first year impact of subsidies for formal home and institutional care on informal care use and medical expenditures these subsidies lead to increases in formal long term care utilization even when accounting for crowd out of private spending our main finding is that the benefits of subsidized home and facility care are heterogeneous across physical function level and therefore that setting policy accordingly has the potential to dramatically reduce medical expenses we also find that formal long term care is a substitute for informal care at the intensive margin but do not find such evidence at the extensive margin the results suggest that publicly financed home care may have limited impact among the more able but that it may be both more cost effective and beneficial than institutional care for the least able

does terrorism affect the stock bond covariance evidence from european countries using daily stock and bond returns data from four european countries france germany spain and great britain that have been the victims of significant terrorist activity this study addresses the issue of whether transnational and or domestic terrorist attacks have affected in any significant manner the time varying stock bond covariance their returns and their variances stock and bond markets can be influenced and determined not only by the usual array of macroeconomic factors but also by security shocks such as a terrorist incident that have the potential to affect investors sentiment and portfolio allocation decisions the issue at hand is addressed using a var p garch 1 1 in mean model and the results reported herein indicate that terrorist attacks trigger a flight to safety effect primarily in france and germany and to a smaller degree in great britain and spain

a house of her own old age assistance and the living arrangements of older nonmarried women abstract i investigate the factors that fostered the rise in separate living quarters for older nonmarried women since mid century by examining the impact of old age assistance on living arrangements in 1940 and 1950 i find that old age assistance substantially increased demand for separate living quarters but that demand depended upon the rules of the program in particular whether children were held legally responsible for the care of their aged parents i argue that more than half of the decline in the fraction of older nonmarried women living with kin from 1950 to 1990 can be attributed to rising social security benefits and expanded eligiblity and to the fact that social security benefits were given with no strings attached

terrorism and its impact on the cost of debt abstract we extend the literature on the costs of terrorism by examining its long term impact on financial markets an underdeveloped strand of research within the terrorism construct specifically we look at its effect on the sovereign risk of 102 countries a much broader sample than examined before which forms the basis of the cost of debt in those countries postulating that it results in a lower credit rating and that this impact is more pronounced in developing as opposed to developed markets in operationalizing the risk of terrorism we utilize the institute for economics and peace s global terrorism index the most comprehensive index constructed to date which incorporates both the economic and social dimensions of terrorism and is based on the global terrorism database covering 104 000 documented incidents the results of the study support the hypothesis that terrorism results in a higher cost of debt for sovereigns and by extension firms in impacted countries in fact a two point increase in terrorism on the utilized 10 point scale on average results in a half notch reduction in a sovereign s credit rating roughly equivalent to a change in outlook furthermore this impact is more pronounced in developing markets where we find that a comparable two point increase in terrorism on average results in an entire notch downgrade in the sovereign credit rating e g from bb to bb finally we find that our model demonstrates predictive power on an out of sample basis and as such could be useful for investors seeking to construct more efficient diversified asset portfolios

terrorism and international business a research agenda terrorism threatens international business ib through its direct and indirect effects as governments tighten security at public sites businesses have become more attractive terrorist targets with important implications for the operations and performance of multinational firms while terrorism has been substantially studied in other fields there has been little scholarly research to address terrorism and the distinctive challenges that it poses for ib in this article we conceptualize terrorism in relation to ib we provide background on the dimensions and effects of terrorism and develop a theoretical grounding for terrorism research by drawing on the literature from ib economics political science and other fields after discussing findings from the literature review we offer a comprehensive agenda for future research regarding the relationship between terrorism and ib our agenda emphasizes the effects of terrorism organizational preparedness company strategy and performance global supply chain and distribution channels and human resource issues our review helps establish a baseline for future empirical research consistent with the early stages of research ib scholars are encouraged to offer useful perspectives and effective solutions that shed needed light on terrorism and help reduce its destructive effects for ib and multinational firms

split sample instrumental variables estimates of the return to schooling this article reevaluates recent instrumental variables iv estimates of the returns to schooling in light of the fact that two stage least squares is biased in the same direction as ordinary least squares ols even in very large samples we propose a split sample instrumental variables ssiv estimator that is not biased toward ols ssiv uses one half of a sample to estimate parameters of the first stage equation estimated first stage parameters are then used to construct fitted values and second stage parameter estimates in the other half sample ssiv is biased toward 0 but this bias can be corrected the splt sample estimators confirm and reinforce some previous findings on the returns to schooling but fail to confirm others

environmental rebounds backfires macroeconomic implications for the promotion of environmentally friendly products abstract this paper develops a dynamic two good clean and dirty goods two sector model to explore the implications of the macroeconomic environmental rebound backfire effect for environmentally friendly product promotions on not only the demand side a subsidy on the clean good consumption but also the supply side a technology promotion in the clean good production the macroeconomic environmental rebound backfire is decomposed into three effects the substitution wealth and sectoral reallocation effects we show that the steady state pollution stock exhibits a u shaped relationship with either demand side or supply side green promotions our calibrated result indicates that in terms of pollution the macroeconomic rebound effectfor the economy as a whole appears to be substantial more pronounced rebound effects are present when the elasticity of substitution between the clean and dirty good consumption is lower the labor supply is more elastic the environmental efficiency of clean goods is lower and the technology level in the clean good production is higher we also show that a pollution rebound can result in a social welfare improvement implying that the rebound effect somewhat improves economic efficiency and so policies aimed at mitigating the rebound effect may be counterproductive from a welfare perspective

a view from the macro side rebound backfire and khazzoom brookes abstract this paper attempts to delineate a few key insights extracted from theoretical macroeconomic considerations of the rebound issue the goal has been to reduce these thoughts to a clear set of assertions that if true would be useful points of reference in the ongoing discussion despite their non empirical nature

lifting the burden state care of the elderly and labor supply of adult children we use a reform in the federal funding of care for the elderly in norway to examine the effects of formal care expansion on the labor supply decisions of middle aged children we find a consistent and significant negative impact of formal care expansion on insured work absences for the adult daughters of single elderly parents this effect is particularly strong for daughters with no siblings who are also more likely to exceed earnings thresholds after the reform we find no impacts of the reform on daughters mobility or parental health and no effects on adult sons

home care reimbursement long term care utilization and health outcomes abstract using a substantial change in medicare reimbursement policy to study the market for home health care i find that the introduction of tightly binding average per patient reimbursement caps led to a large drop in the provision of home care particularly to the least healthy beneficiaries this decline in home health utilization was not offset by increases in institutional long term care or other medical care and there were no associated adverse health consequences however approximately one quarter of the decline in medicare spending was offset by increases in out of pocket expenditures for home health care with the offset concentrated in higher income populations

social security and elderly living arrangements evidence from the social security notch previous studies of the effect of social security on elderly living arrangements generally have relied on data from the distant past or differences in benefits across families or cohorts that potentially were correlated with other determinants of living arrangements using data from the 1980 99 current population surveys we attempt to isolate the causal effect of social security on living arrangements with an instrumental variable approach that relies on the large shifts in benefits for cohorts born from 1910 21 the socalled social security notch over all elderly households the estimated elasticity of living with others with respect to social security income is 0 4 with elasticities of 1 3 and 1 4 for the widowed and divorced respectively most of the effects on living arrangements appear to be concentrated among the lesser educated as well our estimated elasticities are substantially larger than those from previous studies and suggest that reductions in current benefits would alter living arrangements significantly

fuel conserving and using production functions abstract this article compares eight production cost functions used or potentially useful for exploring how energy efficiency gains affect energy consumption we show the practitioner s choice of function can inadvertently pre determine results and make recommendations as to which functions are flexible enough to prevent this we also show pre selected factor substitution elasticities can similarly pre determine results to aid the comparison we decompose the energy consumption rebound effect into intensity and output income effects which also delivers insight into the mechanisms of rebound we conclude by recommending practitioners restrict themselves to either the gallant fourier or the generalized leontief symmetric generalized barnett cost functions as being sufficiently rebound flexible the translog cost function may be suitable given certain conditions and a particular form of the ces solow function is a possible but problematic candidate along the way the article provides a general methodology for similarly examining any arbitrarily defined constant returns to scale production or cost function

efficient intra household allocations a general characterization and empirical tests the neoclassical theory of demand applies to individuals yet in empirical work it is usually taken as valid for households with many members this paper explores what the theory of individuals implies for households that have more than one member we make minimal assumptions about how the individual members of the household resolve conflicts all we assume is that however decisions are made outcomes are efficient we refer to this as the collective setting we show that in the collective setting household demands must satisfy a symmetry and rank condition on the slutsky matrix we also present some further results on the effects on demands of variables that do not modify preferences but that do affect how decisions are made we apply our theory to a series of surveys of household expenditures from canada the tests of the usual symmetry conditions are rejected for two person households but not for one person households we also show that income pooling is rejected for two person households we then test for our collective setting conditions on the couples data none of the collective setting restrictions are rejected we conclude that the collective setting is a plausible and tractable next step to take in the analysis of household behavior

macroeconomic consequences of terror theory and the case of israel abstract this paper analyzes the effect of terror on the economy terror endangers life such that the value of the future relative to the present is reduced hence due to a rise in terror activity investment goes down and in the long run income and consumption go down as well governments can offset terror by putting tax revenues into the production of security facing a tide in terror a government that acts optimally increases the proportion of output spent on defense but does not fully offset the tide thus when terror peaks the long run equilibrium with an optimizing government is of lower output and welfare next we show that this theory of terror and the economy helps to understand changes in trend and business cycle of the israeli economy the estimates show that terror has a large impact on the aggregate economy continued terror at the level of the death toll by about the same size as due to car accidents is expected to decrease annual consumption per capita by about 5 in 2004 had israel not suffered from terror during the last 3 years we estimate that the output per capita would have been 10 higher than it is today

do increases in energy efficiency improve environmental quality and sustainability governments world wide increasingly see energy efficiency as an important aspect of sustainability however there is a debate in the literature as to whether the impact of improved energy efficiency on reducing energy use might be partially or more than wholly offset through rebound and backfire effects this paper clarifies the theoretical conditions under which such effects would occur and explores their likely significance using a computable general equilibrium cge model of the scottish economy we find that for scotland a general improvement in energy efficiency in the production sectors of the economy initially produces rebound effects that eventually grow into backfire energy use ultimately increases in response to an efficiency gain and the ratio of gdp to co2 emissions falls the economic factors underpinning rebound effects are straightforward energy efficiency improvements result in an effective cut in energy prices which produces output substitution competitiveness and income effects that stimulate energy demands however the presence of strong rebound or even backfire does not mean that efficiency enhancing policies are irrelevant rather it suggests that such policies operating alone are insufficient to generate environmental improvements the implication is that a co ordinated portfolio of energy policies is required

terrorism and the world economy abstract it has been argued that terrorism should not have a large effect on economic activity because terrorist attacks destroy only a small fraction of the stock of capital of a country see e g becker g murphy k 2001 prosperity will rise out of the ashes wall street journal october 29 2001 in contrast empirical estimates of the consequences of terrorism typically suggest large effects on economic outcomes see e g abadie a gardeazabal j 2003 the economic cost of conflict a case study of the basque country american economic review 93 113 132 the main theme of this article is that mobility of productive capital in an open economy may account for much of the difference between the direct and the equilibrium impact of terrorism we use a simple economic model to show that terrorism may have a large impact on the allocation of productive capital across countries even if it represents a small fraction of the overall economic risk the model emphasizes that in addition to increasing uncertainty terrorism reduces the expected return to investment as a result changes in the intensity of terrorism may cause large movements of capital across countries if the world economy is sufficiently open so international investors are able to diversify other types of country risks using a unique data set on terrorism and other country risks we find that in accordance with the predictions of the model higher levels of terrorist risks are associated with lower levels of net foreign direct investment positions even after controlling for other types of country risks on average a standard deviation increase in the terrorist risk is associated with a fall in the net foreign direct investment position of about 5 of gdp the magnitude of the estimated effect is large which suggests that the open economy channel impact of terrorism may be substantial

the macroeconomic consequences of terrorism abstract we perform an empirical investigation of the macroeconomic consequences of international terrorism and interactions with alternative forms of collective violence our analysis is based on a rich unbalanced panel data set with annual observations on 177 countries from 1968 to 2000 which brings together information from the penn world table data set the iterate data set for terrorist events and data sets of external and internal conflict we explore these data with cross sectional and panel growth regression analysis and a structural var model we find that on average the incidence of terrorism may have an economically significant negative effect on growth albeit one that is considerably smaller and less persistent than that associated with either external wars or internal conflict as well terrorism is associated with a redirection of economic activity away from investment spending and towards government spending however our investigation also suggests important differences both regarding the incidence and the economic consequences of terrorism among different sets of countries in oecd economies in particular terrorist incidents are considerably more frequent than in other nations but the negative influence of these incidents on growth is smaller

the impact of increased efficiency in the industrial use of energy a computable general equilibrium analysis for the united kingdom the conventional wisdom is that improving energy efficiency will lower energy use however there is an extensive debate in the energy economics policy literature concerning rebound effects these occur because an improvement in energy efficiency produces a fall in the effective price of energy services the response of the economic system to this price fall at least partially offsets the expected beneficial impact of the energy efficiency gain in this paper we use an economy energy environment computable general equilibrium cge model for the uk to measure the impact of a 5 across the board improvement in the efficiency of energy use in all production sectors we identify rebound effects of the order of 30 50 but no backfire no increase in energy use however these results are sensitive to the assumed structure of the labour market key production elasticities the time period under consideration and the mechanism through which increased government revenues are recycled back to the economy

the greenhouse effect the fallacies in the energy efficiency solution abstract the view that widespread improvements in energy efficiency can by themselves do anything to halt the build up of greenhouse gases around the globe is fundamentally unsound it is based on the same fallacies that underlie the claim that energy savings from improving efficiency can substitute for new energy supply the paper by keepin and kats1 claiming that per tonne of coal not burned improvements in energy efficiency are more cost effective than substituting nuclear for coal fired power is therefore an irrelevancy as far as this debate is concerned reductions is energy intensity of output that are not damaging to the economy are associated with increases not decreases in energy demand at the macroeconomic level even within the boundaries of their own flawed approach their attempt2 to refute the critique of their thesis made by jones3 was little more than misdirected grape shot with no discernable connected thread of argument

the price of terror the effects of terrorism on stock market returns and volatility abstract in this paper we investigate the effects of terrorism on the financial markets evidence from six different financial markets shows that terror has a significant impact on both stock markets and the stock market volatility and the magnitude of these effects are larger in emerging markets

tourism s vulnerability and resilience to terrorism personal security is a major concern for tourists most tourists will seek safe and secure destinations and avoid those that have been plagued by terrorism this research quantifies the relationship between terrorism and tourism in 95 different countries and territories using international tourism demand models after controlling for income we find there is no long run effect of terrorism on international tourism demand and the short run effect is quite limited from a global perspective using panel data models only nine countries out of the 95 show a long run impact of terrorism on tourism and 25 countries out of the 95 show a short run impact using time series models implying that international tourism is resilient to terrorism the influence of terrorism is diverse in destinations with different political instability income levels and tourism intensities

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
