renegotiations in the greenhouse international climate policies are being shaped in a process of ongoing negotiations this paper develops a sequential game framework to explore the stability of international climate agreements allowing for multiple renegotiations we analyse how the incentives to reach an international climate agreement in the first period will be impacted by the prospect of further negotiations in later periods and by the punishment options related to renegotiations for this purpose we introduce a dynamic model of coalition formation with twelve world regions that captures the key features of the climate economy impacts of greenhouse gas emissions for a model with one round of renegotiations we find that a coalition of china and the united states is the unique renegotiation proof equilibrium in a game with more frequent renegotiations we find that the possibility to punish defecting players helps to stabilise larger coalitions in early stages of the game consequently several renegotiation proof equilibria emerge that outperform the coalition of china and usa in terms of abatement levels and global payoff the grand coalition however is unstable

price determinants in top quality e auctioned specialty coffees we analyze the price determinants of specialty coffees traded at e auctions we hypothesize that since specialty coffees are a highly differentiated product prices will be determined by both sensory and reputation attributes to test our hypotheses we estimate a hedonic price function using data from central and south american e auctions and calculate the implicit prices of sensory and reputation attributes the results show that market clearing prices are a function of sensory characteristics and reputation variables including third party quality ranking country of origin coffee variety and quantity the additional attribute information disclosed at e auctions results in substantially higher prices relative to conventional commodity coffee market prices

some economics of global warming the greenhouse effect itself is simple enough to understand and is not in any real dispute what is in dispute is its magnitude over the coming century its translation into changes in climates around the globe and the impacts of those climate changes on human welfare and the natural environment these are beyond the professional understanding of any single person the sciences involved are too numerous and diverse demography economics biology and the technology sciences are needed to project emissions atmospheric chemistry oceanography biology and meteorology are needed to translate emissions into climates biology agronomy health sciences economics sociology and glaciology are needed to identify and assess impacts on human societies and natural ecosystems and those are not all there are expert judgments on large pieces of the subject but no single person clothed in this panoply of disciplines has shown up or is likely to this article makes an attempt to forecast the economic and social consequences of global warming due to anthropogenic greenhouse gases and attempting to prevent it

residential hedonic models a rational expectations approach to age effects abstract this paper develops a rational expectations framework for interpreting the coefficient on age in a standard hedonic model the model demonstrates that there are two components to the age coefficient a pure cross sectional depreciation component and a demand side component that changes over time we also show that a constant quality price index with age constant can be estimated by using any repeat sales database that contains the year of construction or property age when fairfax county data are fitted to the model the time series of age coefficients is non stationary they change from negative in the early 1980s to positive in the late 1980s we infer that the demand side component dominated in the latter period

management of transnational commons coordination publicness and treaty formation this paper focuses on the formation of treaties to manage transnational commons when efforts must be coordinated among a minimal sized group so as to make cooperation worthwhile by focusing on mixed strategy equilibria we are con cerned with instances where the intentions of others are uncertain the number of required participants the pattern of payoffs transaction costs and the underlying technology of public supply aggregation are key factors behind the achievement of coordina tion we apply our analysis to explain the outcome of negotiations on stratospheric ozone depletion global warming acid rain and tropical deforesta tion jel q20 d70

the problem of global environmental protection what distinguishes global common property problems and global unidirectional externalities from the ones that arise under a single jurisdiction is that there is no global authority empowered to intervene and regulate use of global environmental resources cooperation is needed the paper discusses when cooperation is most needed and how it might be obtained cooperation might emerge from a noncooperative setting if supergames are played if the actions of any one country are explicitly contingent on the actions undertaken by other countries or if moral concerns lead countries to consider the consequences of their actions for others cooperation emerges in an explicit though limited form when countries commit to regulate themselves in signing international agreements in these cases the signatories cooperate but the agreements are self enforcing an attempt is made to relate these theoretical concepts to the practice of global environmental protection copyright 1990 by oxford university press

improved price indexes for real estate measuring the course of swedish housing prices this paper presents an improved methodology for estimating asset prices for real estate and other durables the method is used to analyze house price dynamics by exploiting an unusually rich and detailed body of data extensive descriptive and financial information on every house sale in sweden during a 12 year period the results confirm the importance of many aspects of quality in affecting the course of housing prices as well as the role of individual specific and idiosyncratic aspects of housing the results are compared with the price trends produced by more primitive methods and published by official sources q 1998 academic press

hedonic price indexes for residential housing a survey evaluation and taxonomy every house is different it is important that house price indexes take account of these quality differences hedonic methods which express house prices as a function of a vector of characteristics such as number of bedrooms and bathrooms land area and location are particularly useful for this purpose i consider here some developments in the hedonic methodology as it is applied in a housing context that have occurred in the last three decades a number of hedonic house price indexes are now available however it is often difficult to see how these indexes relate to each other for this reason i attempt to impose some structure on the literature by developing a taxonomy of hedonic indexes and then show how existing indexes fit into this taxonomy also discussed are some promising areas for future research in the hedonic field in particular greater use needs to be made of spatial econometric and nonparametric methods to exploit the increased availability of geospatial data the main criticisms of the hedonic approach are evaluated and compared with those of the repeat sales and stratified median methods the overall conclusion is that the advantages of the hedonic approach outweigh its disadvantages

collective reputation and quality firms who sell regional or specialty products often share a collective reputation based on aggregate quality collective reputation can be approached as a dynamic common property resource problem we show that for an experience good without firm traceability individual firms have the incentive to choose quality levels that are sub optimal for the group these results support minimum quality standards trigger strategies are analyzed as an alternative solution to this problem finally the implications of these results are discussed as they relate to the case study of washington apples specialty regional authentic and local food products have become a more important part of consumer purchases in recent years firms have responded by marketing food products that come from specific geographic areas this trend in consumers preferences has led the european union to introduce protected designations of origin labels and protected geographical identification labels which provide protection of food names on a geographical or traditional basis ranging from parmesan cheese to such lesser known items such as galician veal in the united states there are popular state products that carry labels such as washington apples idaho potatoes

the influence of proximity to market on bean producer prices in nicaragua transport costs are an important determinant of smallholder welfare in developing countries in particular transport costs influence the prices that smallholders receive for their produce we propose a simple way of quantifying this influence taking the example of bean producers in nicaragua we employ a hedonic price model to estimate the effects of a smallholder s proximity to markets on the prices that he she receives while controlling for other factors such as the volume and quality of beans sold we find that on average each additional minute of travel time reduces farm gate prices by 2 5 cents per quintal based on these results the annual income from bean sales of the average smallholder in our sample would increase by between 24 and 110 usd if travel time to markets were reduced by 25 estimates of this nature can make an important contribution to cost benefit assessments of infrastructure investments

the economics of quality in the specialty coffee industry insights from the cup of excellence auction programs this study estimates price determinants for specialty green coffee auctions using records from the 2004 2010 cup of excellence programs hosted by the alliance for coffee excellence while some literature on coffee has focused on certifications and sustainability labels the discussion of price determinants has been limited this article replicates one of the first publications on price determinants and formulates a new model to more accurately describe the market we include the necessary additional variables and estimate the model using a truncated maximum likelihood estimation technique while sensory quality has a strong effect on price the highest premiums stem from obtaining a top rank compared to other coffees from the same country and north american buyers are more responsive to sensory quality than buyers in asian and european markets jel classifications c24 d44 q13

age time vintage and price indexes measuring the depreciation pattern of houses age time and vintage are key determinants of house prices yet they cannot be included together linearly or as dichotomous variables in hedonic regressions as construction time age of house sale time we introduce a method where the estimates of the age time and vintage effects on prices are obtained in a flexible manner without requiring us to specify a pre determined functional form for either of these variables applying our method to dutch data we find that the estimated depreciation pattern over the life of houses does not follow the functional forms typically specified for the age of houses in hedonic regressions

estimating capital asset price indexes this paper introduces an improved procedure for estimating capital asset price indexes we jointly estimate conventional hedonic and repeat sales models via maximum likelihood procedures thereby taking advantage of the unique features of the individual models and using all the data that are available our model captures depreciation within the repeat sales model and accounts for serial correlation in hedonic data the improvement in precision obtained by estimating the joint model is illustrated by smaller standard errors and narrower interval estimates for the resulting price indexes we also carry out a simulation experiment that shows estimation errors significantly smaller using the joint estimation technique than either of the individual models or the gls estimator of case and quigley 1991

prices of american pinot noir wines climate craftsmanship critics pinot noir a variety originating from burgundy in france is the most expensive category of table wine produced in north america this article is aimed at analyzing its price determinants and focuses on climate critical scores and variables related to the winemaker the main findings are as follows 1 pinot noir prices are mainly determined by temperature and precipitation general temperature increases are not beneficial in fact the optimal climate is similar to that in burgundy 2 the second most important variable is the winemaker his or her skill and reputation have a significant impact on prices 3 expert knowledge in the form of critical scores has little explanatory value

multimarket contact and collusive behavior traditional analyses of industrial behavior typically link the exercise of market power in an industry to internalfeatures such as demand conditions concentration and barriers to entry nevertheless some economists have remained concerned that external factors such as contact across markets may also play a significant role in determining the level of competitiveness in any particular industry in this article we examine the effect of multimarket contact on the degree of cooperation that firms can sustain in settings of repeated competition we isolate conditions under which multimarket contact facilitates collusion and show that these collusive gains are achieved through modes of behavior that have been identified in previous empirical studies of multimarketfirms

measuring asset values for cash settlement in derivative markets hedonic repeated measures indices and perpetual futures two proposals are made that may facilitate the creation of derivative market instruments such as futures contracts cash settled based on economic indices the first proposal concerns index number construction indices based on infrequent measurements of nonstandardized items may control for quality change by using a hedonic repeated measures method an index number construction method that follows individual assets or subjects through time and also takes account of measured quality variables the second proposal is to establish markets for perpetual claims on cash flows matching indices of dividends or rents such markets may help us to measure the prices of the assets generating these dividends or rents even when the underlying asset prices are difficult or impossible to observe directly a perpetual futures contract is proposed that would cash settle every day in terms of both the change in the futures price and the dividend or rent index for that day this paper concerns problems in the measurement of asset values or present values problems that if solved may facilitate the creation of new hedging vehicles new cash settled futures options and other derivative financial products the greatest components of world wealth are not hedgeable at all and

do malaysian house prices follow a random walk evidence from univariate and panel lm unit root tests with one and two structural breaks in this article we apply univariate and panel lagrange multiplier lm unit root tests with one and twostructural breaks proposed by lee and strazicich 2003 2004 and im et al 2005 to examine housing prices for five different housing price indices all housing detached housing semi detached housing terrace housing and high rise housing in 14 states of malaysia to test whether housing prices exhibit a random walk our main finding from the univariate lm unit root tests is that for the vast majority of states housing prices follow a stationary process about a segmented trend the results of the panel lm unit root tests provide overwhelming evidence that house prices are segmented trend reverting

the economics of nested names name specificity reputations and price premia a good can be identified by its region or country of origin the firm that produces it and its product name in other words names can nest within each other to categorize goods with increasing specificity this article develops a conceptual framework for jointly analyzing the effect of product firm and collective reputations on market price the model is estimated via quantile regression with california wine market data the results portray how the structure and relative importance of reputations change as product prices vary specifically reputation premia migrate from collective to specific names as prices increase

international trade in carbon emission rights and basic materials general equilibrium calculations for 2020 restrictions on co emissions affect international trade and the pattern of comparative advantage this paper based on calculations with a static general equilibrium model suggests that international trade in carbon rights is a substitute for trade in energy intensive goods and thus international trading in carbon rights reduces sectoral effects of emission reductions in our model we surprisingly find that free riding by non signatory countries may not render unilateral action ineffective if the oecd unilaterally cuts global emissions by 5 per cent from 1990 levels by the year 2020 emissions by non oecd regions increase but offset less than 15 per cent of this cutback moreover carbon taxes depress international oil prices and create incentives for increased tradc in natural gas

bootstrapping for consistent standard errors for translog price elasticities some evidence from industrial electricity demand abstract this note extends the hirschberg aigner method for deriving price elasticities of various time differentiated electric inputs using estimated cost share elasticities in a translog formulation the h a method leaves out an important component of variance as the estimated cost share elasticities are themselves estimates and are not known quantities this omission leads to overestimating the significance levels of price elasticities with our extension using repeated sampling techniques such as bootstrapping the price elasticity estimates significant when derived through the h a method now become insignificant this points out the need for such an extension when evaluating computed price elasticity estimates particularly when these are used in policy making

is food and drug administration policy governing artisan cheese consistent with consumers preferences abstract united states government policy prohibits the sale of cheese made from unpasteurized milk aged less than 60 days despite contested science behind the policy we use experimental auctions for artisan cheese to estimate the value of pasteurization and age as food safety attributes which is the rationale for the policy we also look at consumers perception of the tradeoff between safety and quality a survey was conducted with participants at farmers markets including experimental auctions and sensory analysis of pasteurized and unpasteurized cheese and questions concerning attitudes about food safety there is no evidence of positive demand for pasteurization and there is no evidence of a tradeoff between safety and quality on average artisan cheese consumers make purchasing decisions based on taste not their attitude toward food safety the results of this study raise questions about the possible extension of a minimum aging period for cheese made from unpasteurized milk

a multivariate repeat sales model for estimating house price indices abstract in the case shiller repeat sales housing price index method the effect of age is embedded into the model s estimates of the time effect this paper develops a multivariate repeat sales model that is able to separately control for the effects of age and time as well as other assets with changing attributes in the construction of price indices the ability to control for an asset s pattern of depreciation should lead to a superior price index when compared to a traditional repeat sales price index the degree of bias between the traditional and multivariate repeat sales models is dependent on the level of price change with respect to age with minimal additional assumptions a pure time time varying age constant price index and a depreciation time constant age varying price index can be constructed using the multivariate repeat sales framework

wine prices and quality ratings a meta regression analysis this article examines the empirical support for the hypothesized hedonic theoretical relation between the price of wine and its quality the examination considers over 180 hedonic wine price models developed over 20 years covering many countries the research identifies that the relation between the price of wine and its sensory quality rating is a moderate partial correlation of 0 30 this correlation exists despite the lack of information held by consumers about a wine s quality and the inconsistency of expert tasters when evaluating wines the results identify a moderate price quality correlation which suggests the existence of strategic buying opportunities for better informed consumers strategic price setting possibilities may also exist for wine producers given the incomplete quality information held by consumers the results from the meta regression analysis point to the absence of any publication bias and attribute the observed asymmetry in estimates to study heterogeneity the analysis suggests the observed heterogeneity is explained by the importance of a wine s reputation the use of the 100 point quality rating scale the analysis of a single wine variety style and the employed functional form the most important implication from the analysis is the relative importance of a wine s reputation over its sensory quality inferring that producers need to sustain the sensory quality of a wine over time to extract appropriate returns the reputation of the wine producer is found not to influence the strength of the price quality relationship this finding does not contradict the importance of wine producer reputation in directly influencing prices

targets for global climate policy an overview a survey of the economic impact of climate change and the marginal damage costs shows that carbon dioxide emissions are a negative externality the estimated pigou tax and its growth rate are too low to justify the climate policy targets set by political leaders a lower discount rate or greater concern for the global distribution of income would justify more stringent climate policy but would imply an overhaul of other public policies catastrophic risk justifies more stringent climate policy but only to a limited extent

the co2 abatement game costs incentives and the enforceability of a sub global coalition abstract this paper studies the economic incentives and the institutional issues governing the outcomes of a short term climate change policy package guided by the united nations framework convention on climate change and the berlin mandate initiatives game theoretic tools and the global trade environment interface are explored within a 26 region 13 commodity computable general equilibrium framework to characterize the incentives of oecd regions to comply with a non binding agreement in a carbon abatement coalition the results showed that in the absence of side payments the achievement of such a coalition might require the design of suitable trade instruments

towards a differentiated modelling of origin effects in hedonic analysis an application to auction prices of specialty coffee abstract origin matters this has been shown by numerous studies using either discrete choice or hedonic approaches to derive implicit prices for origin as a product attribute in most of the hedonic studies intercept dummies were introduced for specific regional origins and statistically significant coefficients of those variables were seen as an indication of either a superior or inferior reputation compared to products from other origins we argue that hedonic pricing models of this type may be too simple to detect the true origin effects if assessments of a product s sensory quality are available and interact with prior beliefs about reputation based on a supply and demand framework to explain auction prices a reduced form hedonic pricing model is suggested that includes intercept as well as slope dummy effects of the regional origin because reputation and the objective product quality are particularly important for markets of differentiated high quality foods and beverages we analyze electronic auction markets for specialty coffees the findings for the cup of excellence data reveal that it is important to distinguish reputation sensory quality and their interaction as determinants of coffee auction prices as well as varying origin impacts across market segments

energy elasticities under divisia and btu aggregation abstract this paper considers two methods of energy aggregation divisia and btu a dynamic demand model is used to study the response of energy use to price and income changes under these two aggregation schemes while the short run responses of energy use are found to be similar the long run response is greater under divisia than under btu aggregation especially in periods of marked changes in energy prices

international environmental problems a simple taxonomy of international environmental problems is developed based on economic considerations the unidirectional externalities are illustrated by the case of one upstream and one downstream country the main problem in this case is an informational one the analysis of regional reciprocal externalities is illustrated by the acid rains in europe it is shown that an efficient solution could be achieved by transferable export rights finally global external problems are discussed with reference to greenhouse effects and extinction of species copyright 1990 by oxford university press

new methodology for constructing real estate price indices applied to the singapore residential market this paper develops a new methodology for constructing a real estate price index that utilizes all transaction price information encompassing both single sales and repeat sales the method is less susceptible to specification error than standard hedonic methods and is not subject to the sample selection bias involved in indexes that rely only on repeat sales the methodology employs a model design that uses a sale pairing process based on the individual building level rather than the individual house level as is used in the repeat sales method the approach extends ideas from repeat sales methodology in a way that accommodates much wider datasets in an empirical analysis of the methodology we fit the model to the private residential property market in singapore between q1 1995 and q2 2014 covering several periods of major price fluctuation and changes in government macroprudential policy the index is found to perform much better in out of sample prediction exercises than either the s p case shiller index or the index based on standard hedonic methods in a further empirical application the recursive dating method of phillips et al 2015a b is used to detect explosive behavior in the singapore real estate market explosive behavior in the new index is found to arise two quarters earlier than in the other indices

the interface between environmental and trade policies last march i gave the frank paish lecture to the society under the title economic life in a greenhouse in my lecture i tried both to survey professional opinion as to some of the possible climatic implications of the greenhouse effect and also to draw out the economic consequences which might follow towards the end of my talk i made reference to some preliminary joint work with randy wigle 2 a colleague at wilfrid laurier university in canada on the global consequences of carbon tax schemes designed to limit and or reduce the build up of co2 emissions a key element underlying the greenhouse effect the written version of the lecture consciously does not reproduce the survey material which made up the first part of the lecture instead it elaborates on the issues raised towards the end it incorporates the work by randy wigle and myself and offers some thoughts on what seems to be a growing issue for the iggos namely the consequences for the international trading system of interactions between trade issues and both future global and current national environmental policies what follows emphasises that if they occur in the next few decades global policy responses3 carbon taxes tradeable permit schemes to environmental concerns will almost certainly have large economic effects among these are likely to be significant effects on trade patterns and trade volumes large interregional effects will also accompany such policies depending upon how such policies are implemented also the i99os may see a growing use of trade measures to achieve objectives set for environmental policies environmental policies towards such countries as brazil the philippines and others where deforestation is a concern may increasingly take the form of threatened trade sanctions unless compliance with global environmental policy objectives occurs 4
