corporate social responsibility of the most highly reputed european and north american firms the objective of this article is double first to analyze using a descriptive analysis the main differences in the level and components of social behaviour between european and north american firms and second to contrast empirically using a multiple linear regression model whether the motives behind corporate social behaviour are different depending on the region or country of the firm with this aim an indicator of social behaviour termed effort in sustainability has been constructed by aggregating the firm s social effort with customers employees community and environment for a sample of the 40 european and north american companies most highly reputed in the years 2003 and 2004 the results obtained indicate that the region or country of the firm influences the level components and motivation of its social behaviour

do non socially responsible companies achieve legitimacy through socially responsible actions the mediating effect of innovation this study investigates the effects on organization s financial performances of first the extent to which the organizations are involved in controversial business activities and second their level of social performance these companies can be considered non socially responsible given the harmful nature of the activities they are involved in managers of these companies may still have incentives to pursue socially responsible actions if they believe that engaging on those actions will help them to achieve legitimacy and improve investors perception about them we develop a comprehensive methodology to investigate these corporate social performance csp related effects in a complex but specific setting to this end we analyze a sample of 202 us firms for the period 2005 2008 using a novel method in this area partial least squares our results indicate that contrary to the general findings in prior literature companies involved in controversial business activities which engage in csp do not directly reduce the negative perception that stakeholders have about them instead we found evidence of a positive mediation effect of csp on financial market based performance through innovation

how resilient are labour markets to natural disasters the case of the 1998 bangladesh flood abstract natural disasters devastate economies as they impede capital accumulation the resilience of labour markets is crucial for the poor who rely on labour to reduce risk we evaluate how the 1998 flood of the century affected wages in bangladesh we find short term declines in agricultural and non agricultural wages agricultural workers who moved towards non agricultural employment to cope benefitted through a lower percentage reduction in short term wages endowed with human capital salaried workers were unable to mitigate income risk extending the eligibility of credit access or relief programmes may preserve local businesses and their employees in the years following a flood

the household response to persistent natural disasters evidence from bangladesh we examine the short run economic impacts of recurrent flooding on bangladeshi households surveyed in 2000 2005 and 2010 in 2010 household income and expenditure survey hies households answered a set of questions on whether they were affected by flood and its likely impacts we identify two treatment affected groups by using the self reported data and historical rainfall data based flood risk index we estimate a difference indifference did model to quantify the impacts on income expenditure asset and labour market outcomes and further extend our analysis to different income and expenditure brackets overall we find robust evidence of negative impacts on agricultural income and expenditure intriguingly the extreme poor i e the bottom 15th quintile experience significant positive impacts on agricultural income in the self reported treatment case

residential construction using the urban growth model to estimate housing supply abstract this article presents an empirical model of housing supply derived from urban growth theory this approach describes new housing construction as a function of changes in house prices and costs rather than as a function of the levels of those variables which previous studies have used empirical tests support this specification over the leading alternative models our estimates show that a 10 rise in real prices leads to an 0 8 increase in the housing stock which is accomplished by a temporary 60 increase in the annual number of starts spread over four quarters

the distribution of the u s capital stock between residential and industrial uses the purpose of the present study is to measure the extent to which an increase in the total capital stock induces an increase in the stock of residential capital i e to measure the marginal propensity of additional capital to be absorbed in residential capital a knowledge of this propensity is important to evaluate the national return on additional saving and to understand the impact that an increased capital stock could have on labor productivity and on the composition of national output the present paper provides both a theoretical and an empirical examination of this question this abstract was borrowed from another version of this item

female headed households and female maintained families are they worth targeting to reduce poverty in developing countries controversy exists over whether to target public and private sector programs to female headed households in developing countries in the attempt to combat poverty and social disadvantage the issues related to the definition and measurement of female headship and the importance of the concept for development policy are discussed a systematic review is then presented of the empirical evidence on the relation between female headship and poverty if female headed households tend to be poorer on average than other households headship should seriously be considered as a potentially useful criterion for targeting antipoverty interventions especially in developing countries where means testing is not feasible the authors examine the potential costs and benefits of targeting female headship and review the experience of chile one of the few countries which has targeted female headship through government intervention and the only one which has evaluation data available the analysis of the project experience is used along with a review of the empirical evidence to answer the question of the desirability and efficiency of targeting female headship in order to reduce poverty in developing countries

consistent estimation of the urban land value function abstract previous studies have found that the urban land value function became flatter during the 19th century apparently due to declining transportation costs and increasing income estimates from these studies imply that housing demand became less elastic over the same period from elastic to unit elastic this paper demonstrates that the latter conclusion is rejected when the area of the city is defined correctly and consistent estimation procedures are used by combining urban and non urban data previous studies underestimated the degree to which the slope of the land value function declined over time when only urban data are used the decline is even greater and the price elasticity of demand for housing is uniformly unit elastic in addition the commonly used box cox transformation is found to be an imprecise method of generalizing functional form and subject to substantial small sample bias which if ignored leads to an underestimate of standard errors

a unified systems perspective of family firm performance abstract theory and practice indicate that in family influenced firms the interaction of the family unit the business entity and individual family members create unique systemic conditions and constituencies that impact the performance outcomes of the family business social system habbershon and williams fam bus rev 12 1999 1 have suggested that these unique systemic family influences can be captured through an analysis of the resources and capabilities of the organization in this paper we pursue their line of thinking and more specifically examine the systemic relationship of resources and capabilities as a source of advantage or constraint to the performance outcomes for family influenced firms the idiosyncratic firm level bundle of resources and capabilities resulting from the systems interactions are referred to as the familiness of the firm wealth creating performance for family influenced firms is a function of the distinctive familiness generated by the family business system the performance model focuses on a particular subset of family influenced firms whose performance goal is transgenerational wealth and wealth creation potential we refer to those families that meet this premise as enterprising families we develop a unified systems model of performance that links the resources and capabilities generated in the enterprising families system with their potential for transgenerational wealth creation

poverty and household size the widely held view that larger families tend to be poorer in developing countries has influenced research and policy the scope for size economies in consumption cautions against this view we find that the correlation between poverty and size vanishes in pakistan when the size elasticity of the cost of living is about 0 6 this turns out to be the elasticity implied by a modified version of the food share method of setting scales by contrast some measures of child nutritional status indicate an elasticity of unity consideration of the weight attached to child versus adult welfare may help resolve the non robustness of demographic profiles of poverty excerpt

shareholder value stakeholder management and social issues what s the bottom line we test the relationship between shareholder value stakeholder management and social issue participation building better relations with primary stakeholders like employees customers suppliers and communities could lead to increased shareholder wealth by helping firms develop intangible valuable assets which can be sources of competitive advantage on the other hand using corporate resources for social issues not related to primary stakeholders may not create value for shareholders we test these propositions with data from s p 500 firms and find evidence that stakeholder management leads to improved shareholder value while social issue participation is negatively associated with shareholder value copyright 2001 john wiley sons ltd

long term impacts of droughts on labour markets in developing countries evidence from brazil abstract climate shocks have well documented impacts on the short term welfare of rural households in developing countries we investigate the impact of droughts on brazilian labour markets we find long term rural wage losses beyond the immediate impact of the drought with affected workers taking five years to catch up with their peers findings are robust to model specification the severity of the losses varies with the dependence on agricultural income supporting the notion of diversifying portfolio strategies in rural areas to reduce climate related income risk

the effects of firm size and industry on corporate giving recent downward trends in corporate giving have renewed interest in the factors that shape corporate philanthropy this paper examines the relationships between charitable contributions firm size and industry improvements over previous studies include an irs data base that covers a much broader range of firm sizes and industries as compared to previous studies and estimation using an instrumental variable technique that explicitly addresses potential simultaneity between charitable contributions and profitability important findings provide evidence of a cubic relationship between charitable giving and firm size and evidence of strong industry effects the plus minus plus regression coefficient sign pattern for the cubic firm size model suggests that small and large firms give more relative to total receipts with lower giving ratios among medium size firms one interpretation for this finding is that small firms are close to the communities they serve while high visibility creates a need for large firm philanthropy strong industry effects provide evidence of inter industry differences in giving culture and or different public relations requirements across industries

does firm size comfound the relationship between corporate social performance and firm financial performance there has been some theoretical and empirical debate that the positive relationship between corporate social performance csp and firm financial performance ffp is spurious and in fact caused by a third factor namely large firm size this study examines this question by integrating three meta analyses of more than two decades of research on 1 csp and ffp 2 firm size and csp and 3 firm size and ffp into one path analytic model the present study does not confirm size as a third factor which would confound the relationship between csp and ffp that is even if firm size is controlled for across studies comprising on average over 15 000 observations csp and ffp remain positively correlated showing a true score corrected path coefficient p of 0 37

corporate social performance and innovation with high social benefits a quantitative analysis this article analyses the link between innovation with high social benefits and corporate social performance csp and the role that family firms play in this this theme is particularly relevant given the large number of firms that are family owned also the implicit potential of innovation to reconcile corporate sustainability aspects with profitability justifies an extended analysis of this link governments often support socially beneficial innovation with various policy instruments with the intention of increasing international competitiveness and simultaneously supporting sustainable development in parallel firms pursue corporate social responsibility csr and environmental management activities partly in the hope that this will foster such innovation in their organisation alongside their main aim of improving csp hence the main research question of this article is about the association of csp with innovation with high social benefits and the determinants of the potential moderation of this association based on panel data the article analyses the link between csp and innovation and the effect of being a family firm using panel estimation techniques the results point to a moderating role of family firms on the link between innovation with high social benefits and csp the article concludes by assessing the policy implications of this insight

new supply and price dynamics in the singapore housing market in this paper var models are employed to trace the price response of existing houses to the quantity of new units launched by homebuilders in singapore between 1996 and 2009 contrary to the competition hypothesis prediction of a negative reaction it is found that marginal supply granger cause existing house prices in a positive manner the effect is robust to the inclusion of exogenous demand factors as well as price interaction in the primary new houses and secondary existing houses market segments the contagion effect is consistent with the hypothesis that developers due to their ability to predict the market are price leaders in the housing market it is also found that homebuilders exhibit herding behaviour in mimicking each other s timing on when to market their new residential projects

toward a new conception of the environment competitiveness relationship accepting a fixed trade off between environmental regulation and competitiveness unnecessarily raises costs and slows down environmental progress studies finding high environmental compliance costs have traditionally focused on static cost impacts ignoring any offsetting productivity benefits from innovation they typically overestimated compliance costs neglected innovation offsets and disregarded the affected industry s initial competitiveness rather than simply adding to cost properly crafted environmental standards can trigger innovation offsets allowing companies to improve their resource productivity shifting the debate from pollution control to pollution prevention was a step forward it is now necessary to make the next step and focus on resource productivity

functional form sample selection and housing demand abstract this paper addresses issues of functional form and sample selection in estimating housing demand urban economic theory suggests that income and price elasticities be allowed to vary with reference incomes and housing prices a generalized box cox estimator rejects linear and log log forms semi log forms are accepted in some cases sample truncation leads to downward biases in permanent income regressions but to slightly upward biased income elasticities price elasticities are generally unchanged

flood insurance wealth redistribution and urban property values abstract this paper examines the economics of the wealth transfer created by the national flood insurance program nfip by its very nature nfip is unique in that it subsidizes existing homeowners but not new construction thus for comparable properties the gain captured by existing homeowners is the difference between selling prices of equivalent qualified and nonqualified properties using standard hedonic pricing models we empirically test the impact of subsidized and nonsubsidized flood insurance on property values

the allocation of capital between residential and nonresidential uses taxes inflation and capital market constraints we have constructed a simple two sector model of the demand for housing and corporate capital economic growth and an increase in the inflation rate were then simulated with a number of model variants the model and simulation experiments illustrate both the tax bias in favor of housing and the manner in which the increase in inflation between 1965 and 1978 magnified it the existence of capital market constraints offsets the bias against corporate capital but it introduces a sharp inefficient reallocation of housing from less wealthy constrained households to wealthy households who do not have gains on mortgages and are not financially constrained

the corporate social performance financial performance link strategic managers are consistently faced with the decision of how to allocate scarce corporate resources in an environment that is placing more and more pressures on them recent scholarship in strategic management suggests that many of these pressures come directly from sources associated with social issues in management rather than traditional arenas of strategic management using a greatly improved source of data on corporate social performance this paper reports the results of a rigorous study of the empirical linkages between financial and social performance corporate social performance csp is found to be positively associated with prior financial performance supporting the theory that slack resource availability and csp are positively related csp is also found to be positively associated with future financial performance supporting the theory that good management and csp are positively related 1997 by john wiley sons ltd

effect of flood on agricultural wages in bangladesh an empirical analysis summary this paper analyzes the effects of riverine floods on agricultural wages in bangladesh drawing upon the district wise monthly data over 1979 2000 we model wages as a dynamic process we find that floods have positive implications for wages in the long run in flood months however agricultural wages decline in the inundated districts we obtain difference in difference estimates to show that the magnitude of impact of flood depends on the relative flood proneness of a district and the relative severity of flood conditions our results indicate that favorable demand and supply conditions in the agricultural labor market can mitigate the impact of disasters on wages in bangladesh

overlapping neighborhoods and housing externalities abstract this paper explores the roles of distance and feedback in neighborhood effects conventional models employ positive feedback and feature neighborhoods that stand apart like islands when neighborhoods overlap a change in land use in one location can induce changes in land use across the city furthermore equilibrium land use is unlikely to be symmetric with negative feedback indirect neighborhood effects can lead to comparative static changes in density and price that cycle these cycles can reduce the ability of coarse zoning to achieve an optimum and can make measurement of neighborhood effects a difficult undertaking

does contingent repayment in microfinance help the poor during natural disasters abstract microfinances in bangladesh introduced a contingent repayment system beginning in 2002 which allowed rescheduling of savings and installments during natural disasters for affected members this paper is one of the first attempts to evaluate the system employing a unique dataset in using evidence from a flood in 2004 the author found that rescheduling plays the role of a safety net by decreasing the probability that people skip meals during negative shocks by 5 1 per cent this effect is even higher on the landless and females this study attempts to contribute to the issue regarding the poverty reduction effect of microfinances

does social performance really lead to financial performance accounting for endogeneity the empirical relationship between a firm s social performance and its financial performance is still not well established in the literature despite more than 30 years of research and more than 100 empirical studies on the issue the results are still mixed we argue that the heterogeneous results found in previous studies are not due exclusively to problems related with the measurement instruments or the samples used instead we posit that a more fundamental problem related with the endogeneity of social strategic decisions could be driving most of the empirical findings we show that using a panel data of 658 firms from 1991 to 2005 how some of the results found in previous research change and some are even reversed when endogeneity is properly taken into account

the impact of natural disasters on household income expenditure poverty and inequality evidence from vietnam natural disasters are expected exacerbate poverty and inequality but little evidence exists to support the impact at household level this article examines the effect of natural disasters on household income expenditure poverty and inequality using the vietnam household living standard survey in 2008 the effects of a natural disaster on household income and expenditure corrected for fixed effects and potential endogeneity bias are estimated at 6 9 and 7 1 declines in vietnamese household per capita income and expenditure respectively natural disasters demonstrably worsen expenditure poverty and inequality in vietnam and thus should be considered as a factor in designing poverty alleviation policies

coping with flood role of institutions in bangladesh the article examines the coping strategies that rural households adopted during the 1998 flood in bangladesh and assesses its impact on household welfare including coping and vulnerability both vulnerability and poverty have in general declined in bangladesh yet 60 of rural households adopted a coping of one type or another and about half of rural households were both vulnerable as well as found to adopt any coping mechanism during the 1998 flood household level panel data analysis confirms that the flood reduced both consumption and asset and forced many households to adopt some coping mechanisms to mitigate the adverse effects of flood consequently natural disaster such as flooding increases households vulnerability to poverty however post flood bumper crop production and operation of targeted programs such as microfinance helped compensate the losses of flood

the macroeconomic consequences of disasters abstract natural disasters have a statistically observable adverse impact on the macro economy in the short run and costlier events lead to more pronounced slowdowns in production yet interestingly developing countries and smaller economies face much larger output declines following a disaster of similar relative magnitude than do developed countries or bigger economies a close study of the determinants of these adverse macroeconomic output costs reveals several interesting patterns countries with a higher literacy rate better institutions higher per capita income higher degree of openness to trade and higher levels of government spending are better able to withstand the initial disaster shock and prevent further spillovers into the macro economy these all suggest an increased ability to mobilize resources for reconstruction financial conditions also seem to be of importance countries with more foreign exchange reserves and higher levels of domestic credit but with less open capital accounts appear more robust and better able to endure natural disasters with less adverse spillover into domestic production

are female headed households more food insecure evidence from bangladesh summary this paper uses household and village level survey data to investigate the food security of male and female headed households in bangladesh with particular attention to indigenous ethnic groups and finds no significant differences in the food security between these two types of households the absence of social and cultural restrictions among the indigenous groups permitting their females greater freedom to participate in the labor force coupled with informal redistributive mechanism is attributed to their less food insecurity this result indicates that noneconomic institutions can significantly impact economic outcomes such as food security

the construct validity of the kinder lydenberg domini social performance ratings data carroll 1991 encouraged researchers in social issues management sim to continue to measure corporate social performance csp from a variety of different perspectives utilizing a variety of different measures in addition wolfe and aupperle 1991 and others have asserted that there is no single best way to measure csp and that multiple measures and perspectives help develop the field however pfeffer 1993 suggest that a lack of consistent measurement has constrained organization studies and by implication the field of social issues management in its development as a field it may be in the best interest of social issues management researchers to try to development a common body of measures and data recently kinder lydenberg and domini co kld a social choice investment advisory firm has made available their social performance database the kld data have potential to become a widely accepted set of csp measures the purpose of this paper is to present a construct validity study comparing the kld data to other measures of csp

the demand for tenure security in developing countries abstract we use survey data for manila the philippines to estimate hedonic functions for formal and squatter housing values we show that on average a rented squatter unit in manila would rent for 15 percent more if it were a formal sector unit an owned squatter unit would sell for 25 percent more if it were a formal sector unit these percentages are interpreted as eviction risk discount for squatter dwellings we conclude that assistance projects that provide secure tenure over a wide area will bestow comparatively greater benefits on lower income households and to those in newer less established settlements since the risks that they bear initially are greater

owner occupied housing capital gains and the tax reform act of 1986 abstract previous homeowners face a nonlinear kinked budget constraint because they can avoid paying tax on the capital gain from the sale of their home if they purchase a more expensive home when they move simulation results suggest that the tax reform act of 1986 tra86 has enhanced the importance of the capital gains kink by raising the after tax cost of housing through lower marginal income tax rates while increasing the tax rate on capital gains as a result a reduction in the capital gains tax rate would reduce housing demand as some families currently at the kink would buy a less expensive home our findings also indicate that the level of excess burden increases with the capital gains tax rate but that tra86 reduced the size of implicit price subsidies received by owner occupiers and related deadweight loss by roughly one half however the distribution of benefits and deadweight loss from the favorable tax treatment of housing remains heavily weighted to higher income families in addition the size of the implicit housing subsidy and related distortion is sensitive to the level of mortgage rates

redefining innovation eco innovation research and the contribution from ecological economics while innovation processes toward sustainable development eco innovations have received increasing attention during the past years theoretical and methodological approaches to analyze these processes are poorly developed against this background the term eco innovation is introduced in this paper addressing explicitly three kinds of changes towards sustainable development technological social and institutional innovation secondly the potential contribution of neoclassical and co evolutionary approaches from environmental and innovation economics to eco innovation research is discussed three peculiarities of eco innovation are identified the double externality problem the regulatory push pull effect and the increasing importance of social and institutional innovation while the first two are widely ignored in innovation economics the third is at the least not elaborated appropriately the consideration of these peculiarities may help to overcome market failure by establishing a specific eco innovation policy and to avoid a technology bias through a broader understanding of innovation finally perspectives for a specific contribution of ecological economics to eco innovation research are drawn it is argued that methodological pluralism as established in ecological economics would be very beneficial for eco innovation research a theoretical framework integrating elements from both neoclassical and evolutionary approaches should be pursued in order to consider the complexity of factors influencing innovation decisions as well as the specific role of regulatory instruments and the experience gathered in ecological economics integrating ecological social and economic aspects of sustainable development is highly useful for opening up innovation research to social and institutional changes 2000 elsevier science b v all rights reserved

determinants of environmental innovation new evidence from german panel data sources abstract in most cases empirical analyses of environmental innovations based on firm level data relied on surveys for one point in time these surveys allow for the inclusion of many explanatory variables such as different policy instruments or the influence of pressure groups but it is not possible to address the dynamic character of environmental innovations this paper uses two german panel databases the establishment panel of the institute for employment research iab and the mannheim innovation panel mip of the centre for european economic research zew to explore the determinants of environmental innovations the econometric estimations show that the improvement of the technological capabilities knowledge capital by r d triggers environmental innovations environmental regulation environmental management tools and general organizational changes also encourage environmental innovation a result that has also been postulated by the famous porter hypothesis

innovation ethics and entrepreneurship this paper is a response to ray s 2004 recent proposal that the intellectual property rights ipr attached to potentially life saving life sustaining innovations should become public goods in cases where markets are either unable or unwilling to pay for the creation of the intellectual property using a free market approach to innovation based on western moral philosophy we suggest that treating intellectually protected life saving life sustaining innovations as public goods will likely reduce social welfare over the long term

natural disasters household welfare and resilience evidence from rural vietnam summary the study uses commune fixed effects regressions to estimate the effect of natural disasters on welfare and poverty of rural households in vietnam and subsequently examines household and community characteristics that can strengthen resilience of households to natural disasters we find that all the three disaster types considered in this study including storms floods and droughts have negative effects on household income and expenditure households in communes with higher mean expenditure and more equal expenditure distribution are more resilient to natural disasters access to micro credit internal remittances and social allowances can help households strengthen the resilience to natural disasters

the growth aftermath of natural disasters this paper provides a description of the macroeconomic aftermath of natural disasters it traces the yearly response of gross domestic product growth both aggregated and disaggregated into its agricultural and non agricultural components to four types of natural disasters droughts floods earthquakes and storms the paper uses a methodological approach based on pooling the experiences of various countries over time it consists of vector auto regressions in the presence of endogenous variables and exogenous shocks varx applied to a panel of cross country and time series data the analysis finds heterogeneous effects on a variety of dimensions first the effects of natural disasters are stronger for better or worse on developing than on rich countries second while the impact of some natural disasters can be beneficial when they are of moderate intensity severe disasters never have positive effects third not all natural disasters are alike in terms of the growth response they induce and perhaps surprisingly some can entail benefits regarding economic growth thus droughts have a negative effect on both agricultural and non agricultural growth in contrast floods tend to have a positive effect on economic growth in both major sectors earthquakes have a negative effect on agricultural growth but a positive one on non agricultural growth storms tend to have a negative effect on gross domestic product growth but the effect is short lived and small future research should concentrate on exploring the mechanisms behind these heterogeneous impacts

shocks and asset dynamics in ethiopia abstractthis article uses household survey panel data of 416 rural households to study asset dynamics in the northern highlands of ethiopia and the response of assets to shocks the period under examination 1996 2003 was marked by severe environmental shocks including a series of droughts the article empirically studies the nature of household asset paths over time using as the point of departure the theory on precautionary savings behavior results indicate that the response of assets to weather shocks the differential effect of these shocks on liquid and less liquid forms of wealth holdings and the nature of asset dynamics are all consistent with the implications of a precautionary motive for holding wealth

determinants of environmental innovation in us manufacturing industries abstract this paper provides new evidence on the determinants of environmental innovation we employ panel data models to study how environmental innovation by us manufacturing industries responded to changes in pollution abatement expenditures and regulatory enforcement during the period 1983 through 1992 we find that 1 environmental innovation as measured by the number of successful environmental patent applications granted to the industry responded to increases in pollution abatement expenditures however 2 increased monitoring and enforcement activities related to existing regulations did not provide any additional incentive to innovate we also find some empirical evidence that environmental innovation is more likely to occur in industries that are internationally competitive

what do household surveys really tell us about risk shocks and risk management in the developing world the authors report on a project to explore empirical patterns in risk shocks and risk management using recent household surveys with risk modules from 16 different developing countries natural disasters health shocks economic shocks and asset loss are the most commonly reported types of shocks and especially for the poor often result in bad coping responses that may perpetuate vulnerability the information culled from these survey modules falls short of expectations in several ways

the price elasticity of the supply of single family detached urban housing abstract past attempts to estimate the price elasticity of the supply of housing have erred by using aggregate data many houses are built in areas where the volume of residential construction is low consequently the influence of observations from higher volume areas where costs may be higher is diminished this problem is eliminated by using cross sectional data from 61 different american urban areas for a total of 223 observations from 1976 to 1981 to estimate a translog cost function for housing the supply elasticity is found to be infinite

naturally negative the growth effects of natural disasters abstract growth theory predicts that natural disasters should on impact lower gdp per capita however the empirical literature does not offer conclusive evidence most existing studies use disaster data drawn from damage records of insurance companies we argue that this may lead to estimation bias as damage data and the selection into the database may correlate with gdp we build a comprehensive database of disaster events and their intensities from primary geophysical and meteorological information in contrast to insurance data our geomet data reveal a substantial negative and robust average impact effect of disasters on growth the worst 5 disaster years come with a growth damage of at least 0 46 percentage points that average effect is driven mainly by very large earthquakes and some meteorological disasters poor countries are more strongly affected by geophysical disasters rich more by meteorological events international openness and democratic institutions reduce the adverse effect of disasters

satellites self reports and submersion exposure to floods in bangladesh abstract a burgeoning climate economy literature has uncovered many effects of changes in temperature and precipitation on economic activity but has made considerably less progress in modeling the effects of other associated phenomena like natural disasters we develop new objective data on floods focusing on bangladesh we show that rainfall and self reported exposure are weak proxies for true flood exposure these data allow us to study adaptation giving accurate measures of both long term averages and short term variation in exposure this is important in studying climate change impacts as people will not only experience new exposures but also experience them differently

tenure security and urban squatting while recent studies have shown that up to 35 of the total urban population of the third world live in squatter settlements there is a dearth of economic analysis on the phenomenon of squatting this paper attempts to fill this gap the equilibrium model argues that the difference in unit housing prices between the non squatting formal sector of a city and its squatting informal sector reflects the premium associated with a secure tenure status the empirical portion of this paper uses hedonic price techniques to derive the average premium on tenure security in a medium sized philippine city davao results show that formal sector unit dwelling prices are about 18 renters to 58 owners more than in the informal sector these equilibrium price differentials were found to be greater for lower income groups larger household sizes and households with older heads for renters and younger heads for

on the existence of cournot equilibrium this paper examines the existence of n firm cournot equilibrium in a market for a single homogeneous commodity it proves that if each firm s marginal revenue declines as the aggregate output of other firms increases which is implied by concave inverse demand then a cournot equilibrium exists without assuming that firms have nondecreasing marginal cost or identical technologies also if the marginal revenue condition fails at a potential optimal point there is a set of firms such that no cournot equilibrium exists the paper also contains an example of nonexistence with two nonidentical firms each with constant returns to scale production
