a principal agent problem with heterogeneous demand distributions for a carbon capture and storage system abstract mechanism design problems optimize contract offerings from a principal to different types of agents who have private information about their demands for a product or a service we study the implications of uncertainty in agents demands on the principal s contracts specifically we consider the setting where agents demands follow heterogeneous distributions and the principal offers a menu of contracts stipulating quantities and transfer payments for each demand distribution we present analytical solutions for the special case when there are two distributions each taking two discrete values as well as a method for deriving analytical solutions from numerical solutions we describe one application of the model in carbon capture and storage systems to demonstrate various types of optimal solutions and to obtain managerial insights

frictionless commerce a comparison of internet and conventional retailers there have been many claims that the internet represents a new nearly frictionless market our research empirically analyzes the characteristics of the internet as a channel for two categories of homogeneous products books and cds using a data set of over 8 500 price observations collected over a period of 15 months we compare pricing behavior at 41 internet and conventional retail outlets we find that prices on the internet are 9 16 lower than prices in conventional outlets depending on whether taxes shipping and shopping costs are included in the price additionally we find that internet retailers price adjustments over time are up to 100 times smaller than conventional retailers price adjustments presumably reflecting lower menu costs in internet channels we also find that levels of price dispersion depend importantly on the measures employed when we compare the prices posted by different internet retailers we find substantial dispersion internet retailer prices differ by an average of 33 for books and 25 for cds however when we weight these prices by proxies for market share we find dispersion is lower in internet channels than in conventional channels reflecting the dominance of certain heavily branded retailers we conclude that while there is lower friction in many dimensions of internet competition branding awareness and trust remain important sources of heterogeneity among internet retailers

characterization of a class of moral hazard adverse selection games abstract studying a principal agent game in which the agent alone observes the state of the world and reports it but the moral hazard is not reducible shows that if the principal uses all signals then no solution exists i e there is no contract that elicits truth telling and motivates the agent to exert effort when the principal does not use signals on the state of the world that seem irrelevant a solution exists in which some of the ex post signals on outcome are not used even though they obey the informativeness condition of holmstrom bell journal of economics 1979 10 74 91

does foreign direct investment impede environmental quality in high middle and low income countries abstract under a multivariate framework this paper aims to investigate the nonlinear correlation between foreign direct investment and environmental degradation for high middle and low income countries with economic growth and energy consumption as additional determinants of environmental degradation all variables were found to be nonstationary and cointegrated based on recent panel data unit root tests and cointegration techniques on applying fully modified ordinary least squares fmols the long run results suggest the presence of an environmental kuznets curve in turn foreign direct investment increases environmental degradation thus confirming the pollution haven hypothesis phh moreover the bidirectional causality between co2 emissions and foreign direct investment is observed globally the findings are sensitive to different income groups and regional analyses in particular these empirical findings aid sound economic policymaking for improving environmental quality and sustainable economic development

equilibrium properties of auctions and alternative procedures for allocating transferable permits abstract this paper examines the equilibrium properties of a range of auctions and related procedures placing emphasis on the types of procedures that are likely to be of special interest in environmental management applications nash equilibrium properties are first derived for a very general class of auctions for multiple homogeneous or heterogeneous objects or permits next it is shown that given appropriate assumptions three broad classes of public allocation procedures that do not generate revenues for the government would yield participants equal expected profits these classes are 1 incentive compatible auctions where bidders receive equal lump sum refunds 2 non incentive compatible procedures where refunds are a function of participants bids and 3 free initial distribution of permits on a lump sum basis followed by trading via a competitive market the applicability of the general results is then demonstrated by examining the particular non incentive compatible fair division procedure originally suggested by knaster finally implications of the theoretical results for applications including the allocation of transferable discharge permits and water rights are discussed

the role of firm size in bilateral bargaining a study of the cable television industry we examine the effect of buyer merger on bilateral negotiations between a supplier and n buyers merger may have bargaining effects in addition to the usual efficiency effects the effect of merger on the buyers bargaining position depends on the curvature of the supplier s gross surplus function merger enhances worsens the buyers bargaining position if the function is concave convex based on a panel of advertising revenue in the cable television industry our estimates indicate that the gross surplus function for suppliers of program services is convex this result suggests that cable operators integrate horizontally to realize efficiency gains rather than to enhance their bargaining position vis a vis program suppliers

economic growth and pollutant emissions in tunisia an empirical analysis of the environmental kuznets curve abstract this paper investigates the relationship between economic growth and pollutant emissions for a small and open developing country tunisia during the period 1961 2004 the investigation is made on the basis of the environmental kuznets curve hypothesis using time series data and cointegration analysis carbon dioxide co 2 and sulfur dioxide so 2 are used as the environmental indicators and gdp as the economic indicator our results show that there is a long run cointegrating relationship between the per capita emissions of two pollutants and the per capita gdp an inverted u relationship between so 2 emissions and gdp has been found with income turning point approximately equals to 1200 constant 2000 prices or to 3700 in ppp constant 2000 prices however a monotonically increasing relationship with gdp is found more appropriate for co 2 emissions furthermore the causality results show that the relationship between income and pollution in tunisia is one of unidirectional causality with income causing environmental changes and not vice versa both in the short run and long run this implies that an emission reduction policies and more investment in pollution abatement expense will not hurt economic growth it could be a feasible policy tool for tunisia to achieve its sustainable growth in the long run

industrialization electricity consumption and co2 emissions in bangladesh this paper investigates the relationship between industrialization electricity consumption and co2 emissions in case of bangladesh using quarter frequency data over the period of 1975 2010 the ar

estimating demand for local telephone service with asymmetric information and optional calling plans in this paper i study the theoretical and econometric implications of agents uncertainty concerning their future consumption when a monopolist offers them either a unique mandatory nonlinear tariff or a choice in advance from a menu of optional two part tariffs agents uncertainty is resolved through individual and privately known shocks to their types in such a situation the principal may screen agents according to their ex ante or ex post type by offering either a menu of optional tariffs or a standard nonlinear schedule the theoretical implications of the model are used to evaluate a tariff experiment run by south central bell in two cities in kentucky in 1986 the empirical approach explicitly accounts for the existence of informational asymmetries between local telephone users and the monopolist leading to different nested econometric specifications under symmetric and asymmetric information the empirical evidence suggests that there exists a significant asymmetry of information between consumers and the monopolist under both tariff regimes all expected welfare components failed to increase with the introduction of optional tariffs for the estimated value of the parameters copyright 2002 wiley blackwell

the licensing of patents under asymmetric information abstract this paper seeks to explain the use of royalty payments rather than fixed fees in the licensing of patents by the presence of asymmetric information the licensee is assumed to know the value of the patent and makes a single offer of a contract to the licensor it is shown that there is a unique equillibrium satisfying cho and kreps intuitive criterion qualitative properties of the equilibrium contract are derived by considering a continuum of types

the impact of foreign direct investment on environmental quality a bounds testing and causality analysis for turkey abstract this study aims to investigate the impact of foreign direct investment fdi together with gross domestic product gdp the square of gdp and energy consumption on carbon dioxide co2 emissions in turkey over the period 1974 2010 we employ both the bounds test approach which has superior properties especially in small samples and the hatemi j test which takes structural breaks into consideration in the co integration analysis due to the co integration relationship between co2 emissions and other variables the autoregressive distributed lag ardl model is used in order to investigate short and long run elasticity between the variables the long run coefficients of the ardl model indicate that the effect of fdi on co2 emissions is positive but relatively small while the effects of the gdp and energy consumption on co2 emissions are quite considerable moreover the short run coefficients obtained by the error correction model ecm are found to be similar to those of the long run model the findings support the validity of the environmental kuznets curve ekc hypothesis in both time horizons the vector ecm based granger causality test is also applied to investigate the causal link the causality test results indicate the existence of a causality running from all explanatory variables to co2 emissions in the long run overall the findings suggest that turkey should promote energy efficiency with sustainable growth and encourage more fdi inflows particularly in technology intensive and environment friendly industries to improve environmental quality

the principal agent relationship with an informed principal ii common values in many circumstances a principal may have relevant private information when she proposes a contract to an agent we analyze such a principal agent relationship as a noncooperative game the principal proposes a contract which is accepted or rejected by the agent who for most of our analysis has no private information the contract is executed if accepted otherwise the reservation allocation takes effect this allocation may be determined by a pre existing contract which the principal by her proposal is attempting to renegotiate or it may simply be the no trade point in this paper we assume that the principal s information directly affects the agent s payoff before solving the game we discuss pareto efficiency with asymmetric information we define an incentive compatible allocation to be weakly interim efficient wie if there exists no alternative incentive compatible allocation that both parties prefer for all possible beliefs that the agent might have about the principal s private information type we show that any wie allocation is interim efficient ie for some beliefs the rothschild stiglitz wilson rsw allocation relative to the reservation allocation l is the allocation that maximizes the payoff of each type of principal within the class of incentive compatible allocations that guarantee the agent at least the utility he gets from a irrespective of his beliefs about the principal s type the equilibrium set of the contract proposal game consists of the allocations that weakly pareto dominate the rsw allocation thus there is a unique equilibrium outcome if and only if the latter is ie and the equilibrium outcome is the rsw allocation itself after characterizing the equilibrium allocations we study those that are renegotiation proof when either the principal or the agent leads the renegotiation we then compare our contract proposal game which is a signaling model with its screening counterpart we conclude by extending our results to the case in which the agent as well as the principal has private information under the assumption of quasi linear preferences

carbon dioxide emissions and economic growth panel data evidence from developing countries in this paper we test the environment kuznet s curve ekc hypothesis for 43 developing countries we suggest examining the ekc hypothesis based on the short and long run income elasticities that is if the long run income elasticity is smaller than the short run income elasticity then it is evident that a country has reduced carbon dioxide emissions as its income has increased our empirical analysis based on individual countries suggests that jordan iraq kuwait yemen qatar the uae argentina mexico venezuela algeria kenya nigeria congo ghana and south africa approximately 35 per cent of the sample carbon dioxide emissions have fallen over the long run that is as these economies have grown emissions have fallen since the long run income elasticity is smaller than the short run elasticity we also examine the ekc hypothesis for panels of countries constructed on the basis of regional location using the panel cointegration and the panel long run estimation techniques we find that only for the middle eastern and south asian panels the income elasticity in the long run is smaller than the short run implying that carbon dioxide emission has fallen with a rise in income

an econometric study of co2 emissions energy consumption income and foreign trade in turkey abstract this study attempts to empirically examine the dynamic causal relationships between carbon emissions energy consumption income and foreign trade in the case of turkey using the time series data for the period 1960 2005 this research tests the interrelationship between the variables using the bounds testing to cointegration procedure the bounds test results indicate that there exist two forms of long run relationships between the variables in the case of first form of long run relationship carbon emissions are determined by energy consumption income and foreign trade in the case of second long run relationship income is determined by carbon emissions energy consumption and foreign trade an augmented form of granger causality analysis is conducted amongst the variables the long run relationship of co2 emissions energy consumption income and foreign trade equation is also checked for the parameter stability the empirical results suggest that income is the most significant variable in explaining the carbon emissions in turkey which is followed by energy consumption and foreign trade moreover there exists a stable carbon emissions function the results also provide important policy recommendations

foreign direct investment and total factor productivity growth new macro evidence although the role of foreign direct investment fdi in facilitating technology transfer is well known in the literature empirical evidence regarding the effect of fdi on growth is mixed the contradictory results in the literature may be due to the failure to account for endogeneity and for the abortive capacity of the hosting countries using panel data for 49 countries over the period 1974 2008 and the existence of investment promotion agencies in the receiving countries as an instrument our results show that increased fdi stock leads to higher productivity growth we also find a significant positive effect on the interaction between fdi stock and distance to the technological frontier suggesting that the ability of technologically backward countries in absorbing technologies developed at the frontiers increases as more fdi stock is accumulated

symbiosis vs crowding out the interaction of formal and informal credit markets in developing countries abstract it is a common observation in many developing countries that enterprises are active borrowers in both formal and informal credit markets we propose a model in which the formal sector s superior ability in deposit mobilization is traded off against the informational advantage that lenders in the informal sector enjoy the formal sector can screen borrowers by providing only partial financing for projects thereby forcing borrowers to resort to the informal sector for the remainder of the loan we use the model to predict how the market structure responds to changes in the environment and we consider the policy implications of various forms of government intervention

the behavior of the common stock of bankrupt firms the event of reorganization or liquidation will be determined by a court to the extent such legal decisions are insensitive to general market movements perhaps the market risk of the firm s shares is reduced it could be the case that most corporate bankruptices are so fully anticipated that little or no new information is released when bankruptcies are filed casual observation suggests that major corporate bankruptcies do not come as complete surprises trading in listed stocks usually is halted some time before bankruptcy filings stories that a corporation is about to file a bankruptcy petition sometimes appear in the financial press several days prior to the filing more conclusive evidence that the market anticipates corporate bankruptcies has been presented in previous empirical studies the findings of westerfield 4 and aharony jones and swary 1 demonstrated that shareholders experience abnormal losses over periods of from four to six years prior to bankruptcy one of westerfield s cumulative performance measures indicated that shareholders of bankrupt companies lost on average 76 percent of their wealth relative to returns on securities of equivalent risk during the seventy one months preceding the announcement of bankruptcy of course large shareholder losses prior to bankruptcy do not guarantee that additional large losses will not be suffered when bankruptcy is announced to date only limited evidence supporting the existence of a bankruptcy announcement effect has been reported altman 2 found that shareholders suffered an average capital loss of approximately 26 percent during the period from one month before to one month after bankruptcy announcements unfortunately a two month interval is too long to provide a clear measure of the market s reaction to bankruptcy announcements it is possible that most or all of the shareholder losses detected by altman occurred during the month preceding the announcements

the impact of contingent liability on commercial bank risk taking abstract from 1863 1935 regulators imposed contingent liability on bank shareholders to discourage risk taking using data from 1900 to 1915 i find that banks subject to stricter liability rules have lower equity and asset volatility hold a lower proportion of risky assets and are less likely to increase their investment in risky assets when their net worth declines consistent with the hypothesis that stricter liability discourages commercial bank risk taking these findings provide lessons for current bank regulatory policy and show that the shape of the residual claimant s payoff function has a significant impact on managerial incentives and firm performance

does foreign direct investment lead to lower co2 emissions evidence from a regional analysis in china abstract existing studies have been concerned with the relationship between foreign direct investment and co2 emissions in recent years however little attention has been paid to regional differences in china this paper investigates the impact of fdi on china s co2 emissions at the national and regional levels using provincial panel data from 1995 to 2010 the stochastic impacts by regression on population affluence and technology stirpat model was adopted the results suggest that fdi contributes to co2 emission reductions in china fdi s impact on co2 emissions decreases from the western region to the eastern and central regions our findings support the pollution halo hypothesis which claims that foreign firms can export greener technologies from developed to developing countries and conduct business in an environmentally friendly manner

competitive price discrimination we model firms as supplying utility directly to consumers the equilibrium outcome of competition in utility space depends on the relationship u between profit and average utility per consumer public policy constraints on the deals firms may offer affect equilibrium outcomes via their effect on u f rom this perspective we examine the profit utility and welfare implications of price discrimination policies in an oligopolistic framework we also show that an equilibrium outcome of competitive nonlinear pricing when consumers have private information about their tastes is for firms to offer efficient two part tariffs

nonlinear pricing of information goods this paper analyzes optimal pricing for information goods under incomplete information when both unlimited usage fixed fee pricing and usage based pricing are feasible and administering usage based pricing may involve transaction costs it is shown that offering fixed fee pricing in addition to a nonlinear usage based pricing scheme is always profit improving in the presence of nonzero transaction costs and there may be markets in which a pure fixed fee is optimal this implies that the optimal pricing strategy for information goods is almost never fully revealing moreover it is proved that the optimal usage based pricing schedule is independent of the value of the fixed fee a result that simplifies the simultaneous design of pricing schedules considerably and provides a simple procedure for determining the optimal combination of fixed fee and nonlinear usage based pricing the introduction of fixed fee pricing is shown to increase both consumer surplus and total surplus the differential effects of setup costs fixed transaction costs and variable transaction costs on pricing policy are described these results suggest a number of managerial guidelines for designing pricing schedules for instance in nascent information markets firms may profit from low fixed fee penetration pricing but as these markets mature the optimal pricing mix should expand to include a wider range of usage based pricing options minimum fees quantity discounts and adoption levels across the different pricing schemes are characterized strategic pricing responses to changes in market characteristics are described and the implications of the paper s results for bundling and vertical differentiation of information goods are discussed

an empirical analysis of competitive nonlinear pricing abstract we estimate a model of competitive nonlinear pricing with multidimensional preference heterogeneity using individual level data on advertisements bought by local businesses e g doctors electricians from two yellow page directories in one u s city market variation in individual choices and payments allows us to identify the joint density of preferences marginal costs of publishing and common utility parameters our estimates suggest substantial welfare loss due to asymmetric information comparing duopoly outcomes with counterfactual monopoly outcomes we find that with less competition i producer surplus increases substantially ii more low type consumers are excluded iii product variety increases but benefits accrue only to the high type consumers iv total consumer surplus decreases v but its distribution across consumers does not change

hiring and leasing with nonlinear prices this paper examines the problem of a monopolist setting an optimal nonlinear pricing schedule in the face of consumers of unknown type who arrive randomly over time and self select a choice of hire period the major determinant of pricing policy is the customer arrival distribution with the overall level of price higher than in the atemporal yield management nonuniform pricing solution by a margin which increases with the average frequency with which potential customers arrive by contrast the solution is generally fairly insensitive to variations in the time rate of discount although there is a tendency for the rate of price discount to increase with increases in the time discount rate

information exchange and distributional implications of price discrimination with internet marketing in agriculture a price discrimination model is proposed to explain why firms provide extraneous information on internet sites selling agricultural inputs whether an informative site is offered depends on price discrimination potential which depends on how much farmers reveal heterogeneity by internet behavior price discrimination is greater if information benefits are negatively correlated with farm size or other characteristics explaining why extraneous not product related information is offered on internet sales sites price discrimination adversely affects some farmers but may be beneficial on average because it generates free information outcomes depend on whether internet users are aware of price differentials on the basis of clickstream information

price discrimination using linear and nonlinear pricing simultaneously abstract price discrimination practiced by using linear and nonlinear pricing simultaneously raises the average price for heterogenous consumers paying linear price but lowers for homogeneous group who pay nonlinear price discrimination lowers consumer surplus for both groups but increases total surplus

consumption of economic information in agriculture we develop a model of decision makers demand for agricultural economic information services this modeltreats choice of externaldecision support services as a function of actors assessment of how alternative investments in information complement their internal competencies data from a survey in four commodity systems are used to evaluate hypotheses as to how human capital and functional role of actors in commodity systems affect demand for variously formatted information by focusing on three axes of heterogeneity diversity among decision makers information service providers and information we are abl e to identify key structuraland functionalrel ationships in agricultural economic information systems

optimal nonlinear pricing by a monopolist with information ambiguity we consider the optimal nonlinear pricing by an ambiguity averse monopolist the monopolist s subjective belief about the distribution of buyers is described by contamination of an additive probability we find that under a maxmin utility decision rule and with a continuum of buyers ambiguity aversion leads to bunching at the bottom in the optimal contract and the distortion at the bottom is reduced other high valuation buyers are offered the same quantity as in the case without ambiguity but they get a greater discount

price discrimination and patent policy patent and antitrust policy are often presumed to be in conflict as an important example there is ongoing controversy about whether price discrimination by a patent holder is an illegal or socially undesirable exploitation of monopoly power in this article we show that no conflict exists in many price discrimination cases even ignoring the dynamic effects on incentives for innovation third degree price discrimination by patent holders can raise static social welfare in fact pareto improvements may well occur welfare gains occur because price discrimination allows patent holders to open new markets and to achieve economies of scale or learning further even in cases where discrimination incurs static welfare losses it may be efficient relative to other mechanisms such as length of patent life for rewarding innovators with profits

price discrimination through refund contracts in airlines this paper shows how an airline monopoly uses refundable and non refundable tickets to screen consumers who are uncertain about their travel our theoretical model predicts that the difference between these two fares diminishes as individual demand uncertainty is resolved using an original data set from u s airline markets we find strong evidence supporting our model price discrimination opportunities through refund contracts decline as the departure date nears and individuals learn about their demand

revenue implications of money creation under leviathan most governments possess a monopoly franchise in the creation of money economists provide an analytical justification for this institutional arrangement either in terms of the use of monetary aggregates for macro economic stabilization or in terms of the alleged inability of competitive markets to generate tolerably efficient monetary results any complete case for the government s monetary monopoly must however depend on a comparison of market and political arrangements a comparison that requires predictions about how governments are likely to behave once a monopoly franchise is assigned similarly such predictions are crucial in evaluating restrictions that might be imposed on the government s exercise of its money creation power in designing a monetary constitution in the analysis of political arrangements the revenue implications of the money creation power are probably more significant than considerations of either macro economic stability or optimality in the money supply although those revenue implications are incidental to demonstrating the nature of market failure in monetary arrangements they are fundamental in understanding how the government might exploit a monopoly in money creation once granted our interest in the revenue effects of money creation stems from a broader study of constitutional restrictions on the revenueraising authority of government see our book the power to create money is naturally encompassed in this restrictions on the revenue raising power must embody restrictions on the power to create money consequently the fiscal constitution has important implications for the monetary constitution in this paper we examine both the revenue implications of money creation and desirable consitutional restrictions on the money creation power within the context of a specific model of political processes

optimal labour contracts under asymmetric information an introduction the review of economic studies has instituted a new series of lectures to be given annually by a younger british economist at the association of university teachers of economics meetings the choice of lecturer is determined by a panel whose members are currently professors hahn mirrlees and nobay this paper is a revised version of the first lecture in the series it was presented at the aute meeting held at the university of surrey in april 1982 and was refereed in the usual way mak

cost functions in non linear pricing abstract this paper compares the optimal selling strategies with symmetric and asymmetric information when monopolist s cost function depends both on individual and aggregate production we show how standard underproduction and higher exclusion with incomplete information are affected

monopoly with incomplete information recent theoretical research on principal agent relationships has emphasized incentive problems that arise when the parties involved are constrained by either asymmetric information or their inability to monitor each other s actions here we concentrate on the former constraint and consider the case of a single principal the monopolist the main contribution is to show that under a separability assumption strong conclusions can be drawn about the nature of optimal incentive schemes although the primary focus is on optimal quantity discounts in a monopolized market the results also shed light on related topics such as optimal income taxation and commodity bundling

optimal nonuniform prices we consider optimal nonuniform pricing schedules where the price depends upon the amount purchased such schedules are regularly used by public utilities and other services welfare optimal nonuniform prices are related to the theory of optimal uniform prices developed by ramsey we characterize situations in which upward or downward discontinuities in pricing schedules are optimal our results are applicable to a number of related problems including optimal taxation insurance and incentives economic theory has confined most of its attention to markets with uniform prices in which the price per unit charged is invariant to the level of a customer s purchases this focus is warranted when goods are resellable since any attempt to charge nonuniform prices could be circumvented by reselling amongst customers but when goods are not resellable nonuniform prices are not only possible but common public utilities have declining block pricing with lower unit charges for large levels of consumption many agencies providing services including communications transportation even education use two part pricing with a fixed entry or retainer charge and a further charge per unit consumption nonuniform price schedules can be expected to be ever more common as services become a larger fraction of total output the increasing prevalence of nonuniform pricing policies have made them the focus of recent public and economic attention oi 1971 feldstein 1972 and ng and weisser 1974 have examined optimal two part pricing policies leland and meyer 1976 examine block pricing and show by example that optimal welfare policies may require nonuniform prices if zero profit constraints are binding in this paper we consider arbitrary nonuniform pricing policies using variational techniques two part and block pricing schedules are of course special cases of the environment we consider the work most closely related to our examination is the seminal paper by spence 1978 and subsequent analysis by roberts 1979 spence however does not pay explicit attention to the key role played by constraints on optimal pricing schedules roberts considers upward price discontinuities which lead to bunching of consumers at a given level of consumption but not downward price discontinuities which lead to regions in which no consumer chooses to consume gaps bunching or gaps may appear in the optimal price schedule even when underlying demand and cost functions are smooth and well behaved the prevalence of discontinuous pricing schedules e g the block pricing structures of public utilities argues that these questions are of practical as well as theoretical interest

the simple economics of extortion evidence from trucking in aceh this paper tests whether the behavior of corrupt officials is consistent with standard industrial organization theory we designed a study in which surveyors accompanied indonesian truck drivers on 304 trips during which they observed over 6 000 illegal payments to police soldiers and weigh station attendants using plausibly exogenous changes in the number of checkpoints we show that market structure affects the level of illegal payments we further show that corrupt officials use complex pricing schemes including third degree price discrimination and a menu of two part tariffs our findings illustrate the importance of considering the market structure for bribes when designing anticorruption policy

contract theory and implications for perennial energy crop contracting abstract this article provides an overview of modern contract theory and discusses the implications of the theory for contracting for perennial dedicated energy crops we discuss some of the unique challenges of contracting for dedicated energy crops used for the production of advanced biofuels and survey some of the relevant concepts and research from the contract theory literature to address these challenges we focus primarily on the mechanism design or complete contracts approach to contracting which involves optimizing some objective function e g profits costs etc with respect to contract terms subject to important incentive constraints the solution to these optimization problems typically highlight important tradeoffs that a contract designer needs to consider in order to maximize profits and or minimize costs

energy intensity co2 emissions and the environmental kuznets curve the spanish case this article analyses the role of energy intensity and the relationship between co2 emissions and primary energy in order to explain the evolution of co2 emissions by unit of real gdp it also distinguishes two different meanings of co2 emissions kuznets curve hypothesis the weak and the strong sense it considers the case of spain in the period 1972 1997 as an example in which there is not any evidence supporting this hypothesis in either sense

fdi growth and the asian financial crisis the experience of selected asian countries this paper studies the trends in foreign direct investment fdi flows into selected south east asian and east asian economies after the asian crisis empirical evidence indicates that south east and east asian economies are recovering from the asian crisis with strong output growth driven largely by export growth however output growth in the post crisis period is also accompanied by rising unemployment rates growing government deficits and declining fdi inflows into the south east asian region the declining fdi inflows into south east asia after the crisis is of concern as our empirical results show that fdi is important for output growth in the region our results also suggest that there might have been structural changes in the regional economies that could have led to a downward shift in the output growth of asian economies in the post crisis period this raises the issue of the sustainability of their output growth in the post crisis period

when are local incentive constraints sufficient we study the question of whether local incentive constraints are sufficient to imply full incentive compatibility in a variety of mechanism design settings allowing for probabilistic mechanisms we give a unified approach that covers both continuous and discrete type spaces on many common preference domains including any convex domain of cardinal or ordinal preferences single peaked ordinal preferences and successive single crossing ordinal preferences local incentive compatibility suitably defined implies full incentive compatibility on domains of cardinal preferences that satisfy a strong nonconvexity condition local incentive compatibility is not sufficient our sufficiency results hold for dominant strategy and bayesian nash solution concepts and allow for some interdependence in preferences

a reduced form optimal nonlinear income tax problem abstract for a finite population with quasilinear preferences it is shown how mirrlees optimal nonlinear income tax problem can be simplified to a reduced form problem involving only the allocation of the consumption good this result is a finite version of a proposition established in the continuum by s lollivier and j c rochet

the environmental impact of industrialization and foreign direct investment abstract in recent years the major concern about the environment has been the emissions of greenhouse gases and the consequent impact on climate change there is a huge interest among scholars in examining factors that contribute to environmental degradation in this study we examined the environmental impact of foreign direct investment and industrialization in 36 selected african countries using data for the period 1980 2014 we proxied the environment with a number of factors including carbon dioxide nitrous oxide methane and total greenhouse gases emissions employing the pooled mean group estimation technique we found that the effect of industrialization on the environment is generally insignificant however the effect of foreign direct investment on the environment is found to be largely significant policy implications of these findings are discussed

intertemporal quality discrimination of a durable good monopolist abstract consider a durable good monopolist facing the technology constraint that when he introduces a new product he cannot produce a cheaper variant without a time lag we show that the qualities of his high end and low end products are higher than their efficient quality levels

the effect of urbanization on co2 emissions in emerging economies the theories of ecological modernization and urban environmental transition both recognize that urbanization can have positive and negative impacts on the natural environment with the net effect being hard to determine a priori this study uses recently developed panel regression techniques that allow for heterogeneous slope coefficients and cross section dependence to model the impact that urbanization has on co2 emissions for a panel of emerging economies the estimated contemporaneous coefficients on the energy intensity and affluence variables are positive statistically significant and fairly similar across different estimation techniques by comparison the estimated contemporaneous coefficient on the urbanization variable is sensitive to the estimation technique in most specifications the estimated coefficient on the urbanization variable is positive but statistically insignificant the implications of these results for sustainable development policy are discussed

strategic environmental policy under incomplete information this paper introduces incomplete information into recent analyses of strategic environmental policy it is shown how asymmetric information between planners and producers affects national incentives to impose strategic environmental standards on domestic industries in international oligopolistic competition relative to the full information case incomplete information is likely to mitigate allocative distortions originating from strategic behaviour a countervailing effect tending to raise distortion is however revealed from the analysis this effect is absent when governments intervene in free trade through direct production subsidies the results suggest that incentives to capture foreign rents are less reduced due to private information when environmental standards rather than direct production subsidies are the strategic instrument

profitable pricing when market segments overlap in this paper we analyze profitable pricing strategies when market segments overlap overlapping markets are segments that are not perfectly sealed and leakage between them can occur different consumers are assumed to incur possibly different transaction costs if they choose to purchase in the low price market a monopolist seller knows the distribution of transaction costs across consumers and must choose an optimal pricing strategy in particular the monopolist must decide whether to charge a single price or to price differentiate conditions are derived under which price differentiation will be the most profitable strategy when price differentiation is optimal the equilibrium amount of leakage is determined endogenously unlike the standard economics textbook model of price discrimination in which zero leakage is determined exogenously and is usually given as a necessary condition for price discrimination we show that zero leakage is not necessary for differential pricing to be optimal and that

profit maximizing nonlinear pricing if the preferences of the consumers are represented by utility functions that are differentiable quasi linear and satisfy the single crossing condition the characteristics of the profit maximizing nonlinear outlay schedule for a monopolist are well known we demonstrate that these characteristics are robust against weaker assumptions on the utility functions

does urbanization lead to less energy use and lower co2 emissions a cross country analysis despite the relationship between urbanization energy use and co2 emissions has been extensively studied in recent years little attention has been paid to differences in development stages or income levels most previous studies have implicitly assumed that the impact of urbanization is homogenous for all countries this assumption can be questionable as there are many characteristic differences among countries of different levels of affluence this paper investigates empirically the effects of urbanization on energy use and co2 emissions with consideration of the different development stages using the stochastic impacts by regression on population affluence and technology stirpat model and a balanced panel dataset of 99 countries over the period 1975 2005 the findings suggest that the impact of urbanization on energy use and emissions varies across the stages of development surprisingly urbanization decreases energy use in the low income group while it increases energy use in the middle and high income groups the impact of urbanization on emissions is positive for all the income groups but it is more pronounced in the middle income group than in the other income groups these novel findings not only help advance the existing literature but also can be of special interest to policy makers and urban planners

group buying on the web a comparison of price discovery mechanisms web based group buying mechanisms are being widely used for both business to business b2b and business to consumer b2c transactions we survey currently operational online group buying markets and then study this phenomenon using analytical models we build on the literatures in information economics and operations management in our analytical model of a monopolist offering web based group buying under different kinds of demand uncertainty we derive the monopolist s optimal group buying schedule under varying conditions of heterogeneity in the demand regimes and compare its profits with those that obtain under the more conventional posted price mechanism we further study the impact ofproduction postponement by endogenizing the timing of the pricing and production decisions in a two stage game between the monopolist and buyers our results have implications for firms choice of price discovery mechanisms in e markets and for the scheduling of production and pricing decisions in the presence and absence of scale economies of production

nonlinear pricing and price cap regulation abstract this paper analyzes profit maximizing nonlinear pricing by a firm that is subject to price cap regulation two forms of regulatory constraint are considered i a cap on the firm s average revenue and ii a constraint that the firm must continue to offer each consumer the option of buying at the uniform price optimal nonlinear price schedules in these regimes are shown to have simple characterizations that are related to the nonlinear tariffs that an unregulated monopolist would charge of the regulatory regimes the firm prefers the average revenue constraint to the option constraint and likes uniform pricing least consumers in aggregate prefer the option regime to uniform pricing and like the average revenue constraint least but there are also distributional effects between consumers although the optional tariff regime pareto dominates uniform pricing it is ambiguous whether welfare is higher under uniform pricing or under the average revenue regime an example is used to illustrate the nature of the ambiguity

empirical study on the environmental kuznets curve for co2 in france the role of nuclear energy this paper attempts to estimate the environmental kuznets curve ekc in the case of france by taking the role of nuclear energy in electricity production into account we adopt the autoregressive distributed lag ardl approach to cointegration as the estimation method additionally we examine the stability of the estimated models and investigate the granger causality relationships between the variables in the system the results from our estimation provide evidence supporting the ekc hypothesis and the estimated models are shown to be stable over the sample period the uni direction running from other variables to co2 emissions are confirmed from the casualty tests specifically the uni directional causality relationship running from nuclear energy to co2 emissions statistically provides evidence on the important role of nuclear energy in reducing co2 emissions

bankruptcy costs and the new bankruptcy code bankruptcy costs are the deadweight economic costs of firms going bankrupt they include both ex post bankruptcy costs incurred after a firm s bankruptcy filing such as transactions costs and ex ante bankruptcy costs incurred before the filing such as those resulting from creditors attempts to reduce their losses if bankruptcy occurs and or managers attempts to raise the expected return to equity by increasing the firm s risk 1 this paper has two purposes first it proposes a model of bankruptcy costs which focuses on the costs of inefficient decision making before the firm s actual bankruptcy filing the model implies upper bound expressions for total bankruptcy costs second the new u s bankruptcy code2 went into effect late in 1979 and made important changes in bankruptcy reorganization procedures the paper poses the question of whether the changes made under the new code tend to raise or lower aggregate u s bankruptcy costs we approach this question by calculating the upper bound expressions suggested by the model using parameter values from both before and after the new code took effect from an economic standpoint the most important changes instituted under the new bankruptcy code had the effect of making it more difficult to reorganize firms in bankruptcy previously it was common for failing firms to file for bankruptcy but for prior management to continue to operate the firm in much the same form as before the bankruptcy filing prevented unpaid creditors from suing the firm while a reorganization plan was arranged which cut back most debts from an economic standpoint such a procedure was anomalous since we learn in basic economics that competition in the long run should cause inefficient firms to go out of business as long as failing firms are more likely to be inefficient than firms in general it would seem to be rewarding inefficiency and offsetting

investigating the validity of pollution haven hypothesis in the gulf cooperation council gcc countries this study investigated the validity of the pollution haven hypothesis in the gulf cooperation council gcc countries using a multivariate framework to achieve the goal of this study the non stationary panel techniques were used to examine the hypothesis from 1980 to 2009 based on the pedroni cointegration test results it was found that the variables are cointegrated moreover the fully modified ols results showed that energy consumption and gdp growth increase co2 emission while foreign direct investment inflows have a long run negative relationship with co2 emission furthermore based on the short run granger causality test results fdi has no short run causal relationship with co2 emission and energy consumption while energy consumption and gdp growth have a positive causal relationship with co2 emission thus the results of this study indicate that energy consumption and gdp growth are the source of pollution in the gcc countries and not the foreign direct investment inflows thus the study recommended that these countries should utilize policies to encourage inward foreign investment since it plays an important role in stimulating gdp growth

equivalence between the diamond dybvig banking model and the optimal income taxation model abstract it is shown that the diamond dybvig journal of political economy 96 1983 768 banking model with a continuum of types of agents has the same analytical structure as the standard optimal income taxation model review of economic studies 38 1971 175 review of economic studies 43 1976 261 insights from the income taxation literature immediately imply that a bank run equilibrium exists in the banking model as long as the long term project is sufficiently costly to liquidate

a panel bootstrap cointegration test this paper proposes a bootstrap test for the null hypothesis of cointegration in panel data the test is general enough to allow for dependence both within and between the cross sectional units and is shown to work well in small samples

economic growth and co2 emissions in malaysia a cointegration analysis of the environmental kuznets curve this paper attempts to establish a long run as well as causal relationship between economic growth and carbon dioxide co2 emissions for malaysia using data for the years from 1980 to 2009 the environmental kuznets curve ekc hypothesis was tested utilizing the auto regressive distributed lag ardl methodology the empirical results suggest the existence of a long run relationship between per capita co2 emissions and real per capita gross domestic product gdp when the co2 emissions level is the dependent variable we found an inverted u shape relationship between co2 emissions and gdp in both short and long run thus supporting the ekc hypothesis the granger causality test based on the vector error correction model vecm presents an absence of causality between co2 emissions and economic growth in the short run while demonstrating uni directional causality from economic growth to co2 emissions in the long run

competitive screening under heterogeneous information we study the interplay between informational frictions and second degree price discrimination our theory recognizes that consumers differ in their tastes for quality as well as in the information they possess about available offers which leads to dispersion over price quality menus in equilibrium while firms are ex ante identical we show that their menus are ordered so that more generous menus leave more surplus to consumers of all valuations we explore the cross section of equilibrium menus and variations in market conditions to generate empirical predictions on prices qualities and markups across firms and within a firm s product line for instance more competition may raise prices for low quality goods yet consumers are better off as the qualities they receive also increase the predictions of our model illuminate empirical findings in many markets such as those for cell phone plans yellow pages advertising cable tv and air travel

involuntary unemployment and worker self selection abstract consider a firm that lacks information about the reservation wage or ability of any specific worker but is aware that workers with higher reservation wages tend to be more able on average we show that under a simple condition that the efficiency wage exceeds the lowest reservation wage the optimal hiring policy for the firm involves 1 no wage discrimination and 2 rationing of jobs when demand for its product is low the result also extends to the case where hours of work are variable provided each worker is most productive when working a strictly positive number of hours per week

multiproduct nonlinear pricing typically work on mechanism design has assumed that all private information can be captured in a single scalar variable this paper explores one way in which this assumption can be relaxed in the context of the multiproduct nonlinear pricing problem it is shown that the firm will choose to exclude some low value consumers from all markets a class of cases that allow explicit solution is derived by making use of a multivariate form of integration by parts in such cases the optimal tariff is cost based

ceo compensation in financially distressed firms an empirical analysis this paper studies senior management compensation policy in 77 publicly traded firms that filed for bankruptcy or privately restructured their debt during 1981 to 1987 almost one third of all ceos are replaced and those who keep their jobs often experience large salary and bonus reductions newly appointed ceos with ties to previous management are typically paid 35 less than the ceos they replace in contrast outside replacement ceos are typically paid 36 more than their predecessors and are often compensated with stock options on average ceo wealth is significantly related to shareholder wealth after firms renegotiate their debt contracts however managers compensation is sometimes explicitly tied to the value of creditors claims

the target incentive system vs the price incentive system under adverse selection and the ratchet effect abstract in a dynamic adverse selection type of principal agent relationship where the principal is committed over time to a particular incentive system with fixed structure but variable parameters but not to any intertemporal incentive scheme with both fixed structure and parameters the ratchet effect arises but varies with different incentive systems we show that compared with using prices as the sole planning mode the principal can attenuate the ratchet effect by stipulating targets as well as a result the target incentive system entails higher expected welfare than the price incentive system in a perfect bayesian equilibrium

security pricing and deviations from the absolute priority rule in bankruptcy proceedings claims ultimately awarded to shareholders of firms in reorganization were examined for a sample of 30 filings under the 1978 bankruptcy reform act we measured the amount paid to shareholders in excess of that which they would have received under the absolute priority rule and found that this amount represents on average 7 6 of the total awarded to all claimants evidence is also reported that common share values reflect a significant proportion of value ultimately received in violation of absolute priority suggesting that deviations from the rule were expected by the equity markets the absolute priority rule hereafter apr states that a bankrupt firm s value is to be distributed to suppliers of capital such that senior creditors are fully satisfied before any distributions are made to junior creditors and junior creditors are paid in full before common shareholders bankruptcy reorganization proceedings however are leaving shareholders and junior creditors with valuable assets even when senior claimants receive only partial settlements as barrett and sullivan 1988 noted traditionally shareholders have been last in line their claims on a troubled company s assets have had the lowest priority and their impact on the course of bankruptcy code proceedings generally has been next to nil but lately the balance of power has been shifting warner 1977 provided one of the early discussions of the implications of deviations from the apr baldwin and mason 1983 pp 510 511 examined the resolution of claims in the massey ferguson reorganization and provided no support for the hypothesis that the market believes absolute priority rules will be enforced if the firm defaults on its financial obligations franks and torous 1989 analyzed a sample of bankruptcies that occurred during the period 1970 through 1984 and found that 21 of 27 sample cases exhibited departures from the apr more recently weiss 1990 examined 37 firms that filed for bankruptcy between 1980 and 1986 and reported that 27 of the cases involved apr violations

reverse price discrimination with bayesian buyers this paper studies price discrimination under the situation in which buyers prior valuations are initially observable by a seller but buyers receive further information about a product or service which remains private thereafter the buyers interpret new information via bayes rule we show that in this environment prices are not monotone in buyers prior valuations interestingly this results in the possibility that a seller intentionally offers a higher price to a low valuation buyer rather than a high valuation buyer reverse price discrimination we derive this result in both monopoly and duopoly markets

the resolution of claims in financial distress the case of massey ferguson when a firm s business deteriorates to the point where it cannot meet its financial obligations the firm is said to have entered the state of financial distress the first signals of distress are usually violations of debt covenants coupled with the omission or reduction of dividends some financially distressed firms eventually go bankrupt others recover or manage to settle the claims against them out of court 1 the behavior of firms in financial distress is interesting for two reasons first the costs of financial distress are an important element in capital structure theory in many models 2 these costs are hypothesized to counteract the tax benefits of leverage and lead to an internal optimum for the capital structure of the firm second financial distress has come to be recognized as a state in which contractual claims are incompletely specified standard terms of the debt equity contract are violated when the firm enters financial distress and claimants may then decide not to act according to previously agreed upon rules or legal formulas recent history has provided a number of examples of firms in financial distress including massey ferguson international harvester chrysler and braniff the resolution of claims in these situations often differs from what is predicted by legal rules or standard theoretical models this paper examines the actual resolution of claims in the reorganization of massey ferguson ltd in part i we use time series data on daily stock returns to test different specifications of priority rules for debt and equity claims in part ii we consider whether massey ferguson avoided deadweight costs of financial distress through the restructuring of claims negotiated among creditors during the winter of 1980 81

efficiency properties of non linear pricing schedules without the single crossing condition this paper investigates efficiency properties of profit maximizing non linear outlay schedules it demonstrates that some well known efficiency characteristics of the profit maximizing non linear outlay schedule may not continue to hold when the single crossing condition is relaxed

foreign direct investment inflows and the industrialization of african countries summary this paper examines the relationship between inward foreign direct investment fdi and the industrialization process in africa it uses panel data from 49 countries over the period of 1980 2009 the results indicate that fdi did not have a significant impact on the industrialization of these countries while other variables such as the size of the market the financial sector and international trade were important this study concludes that the role of fdi in the transformation agenda which is currently being discussed in africa should be carefully analyzed to maximize the impact of these capital inflows

all units discounts and double moral hazard abstract an all units discount is a price reduction applied to all units purchased if the customer s total purchases equal or exceed a given quantity threshold since the discount is paid on all units rather than marginal units the tariff is discontinuous and exhibits a negative marginal price cliff at the threshold that triggers the discount this paper shows that all units discounts arise in optimal agency contracts between upstream and downstream firms that face double moral hazard i present conditions under which all units discounts dominate two part tariffs and other continuous tariffs i also examine these tariffs when the upstream market faces a threat of entry in the case considered all units discounts deter entry by less efficient rivals without distorting price and investment whereas continuous tariffs either accommodate such entry or deter it by distorting price and investment

information effects in financial distress the case of seabrook station abstract in 1972 a group of electric utilities announced plans to construct seabrook station a nuclear generating facility in 1988 the lead partner in the venture public service company of new hampshire psnh filed for bankruptcy examination of the stock price effects of a variety of financial events preceding the bankruptcy filing shows that information about cash flows paid to psnh security holders affected the common stock prices of psnh and its seabrook partners whereas information about investment and operating cash flows had little or no effect

monopoly and quality distortion effects and remedies a monopolist that sells in a market in which consumers differ in their willingness to pay for quality will distort and enlarge the range of products offered for sale we examine the positive and normative impacts of remedies used to counteract such distortions for the case of a price ceiling the monopolist improves quality at the low quality end of the market offsetting the distortion induced by the unregulated exercise of monopoly power social welfare can be shown to increase for a sufficiently slight degree of price regulation for minimum quality standards the social welfare implications are ambiguous because the standards may exclude some consumers from the market

why do larger buyers pay lower prices intense supplier competition abstract the paper provides a theoretical explanation of the common claim that larger buyers pay lower prices in the model suppliers compete more aggressively for the business of larger buyers much as they do in boom periods of rotemberg and saloner

regulating a monopolist with unknown costs we consider the problem of how to regulate a monopolistic firm whose costs are unknown to the regulator the regulator s objective is to maximize a linear social welfare function of the consumers surplus and the firm s profit in the optimal regulatory policy prices and subsidies are designed as functions of the firm s cost report so that expected social welfare is maximized subject to the constraints that the firm has nonnegative profit and has no incentive to misrepresent its costs we explicitly derive the optimal policy and analyze its properties in their classic papers dupuit 2 and hotelling 5 considered pricing policies for a bridge that had a fixed cost of construction and zero marginal cost they demonstrated that the pricing policy that maximizes consumer well being is to set price equal to marginal cost and to provide a subsidy to the supplier equal to the fixed cost so that a firm would be willing to provide the bridge this first best solution is based on a number of informational assumptions first the demand function is assumed to be known to both the regulator and to the firm while the assumption of complete information may be too strong the assumption that information about demand is as available to the regulator as it is to the firm does not seem unnatural a second informational assumption is that the regulator has complete information about the cost of the firm or at least has the same information about cost as does the firm this assumption is unlikely to be met in reality since the firm would be expected to have better information about costs than would the regulator as weitzman has stated an essential feature of the regulatory environment i am trying to describe is uncertainty about the exact specification of each firm s cost function in most cases even the managers and engineers most closely associated with production will be unable to precisely specify beforehand the cheapest way to generate various hypothetical output levels because they are yet removed from the production process the regulators are likely to be vaguer still about a firm s cost function 12 p 684 as this observation suggests it is natural to expect that a firm would have better information regarding its costs than would a regulator the purpose of this paper is to develop an optimal regulatory policy for the case in which the regulator does not know the costs of the firm one strategy that a regulator could use in the absence of full information about costs is to give the firm the title to the total social surplus and to delegate the pricing decision to the firm in pursuing its own interests which would then be to maximize the total social surplus the firm would adopt the same marginal cost pricing strategy that the regulator would have imposed if the regulator had

energy consumption economic growth and co2 emissions in middle east and north african countries this article extends the recent findings of liu 2005 ang 2007 apergis et al 2009 and payne 2010 by implementing recent bootstrap panel unit root tests and cointegration techniques to investigate the relationship between carbon dioxide emissions energy consumption and real gdp for 12 middle east and north african countries mena over the period 1981 2005 our results show that in the long run energy consumption has a positive significant impact on co2 emissions more interestingly we show that real gdp exhibits a quadratic relationship with co2 emissions for the region as a whole however although the estimated long run coefficients of income and its square satisfy the ekc hypothesis in most studied countries the turning points are very low in some cases and very high in other cases hence providing poor evidence in support of the ekc hypothesis co2 emission reductions per capita have been achieved in the mena region even while the region exhibited economic growth over the period 1981 2005 the econometric relationships derived in this paper suggest that future reductions in co2 emissions per capita might be achieved at the same time as gdp per capita in the mena region continues to grow

foreign direct investment income and environmental pollution in developing countries panel data analysis of latin america abstract effects of foreign direct investment fdi and income on pollution emissions are examined using time series data from 1980 to 2010 for 14 latin american countries specifically we test the validity of pollution haven hypothesis phh and environmental kuznets curve ekc hypothesis for this region results from panel fixed and random effects models that controlled the effects of physical capital energy human capital population density and unemployment rate indicate the validity of both the phh and ekc hypothesis estimating two separate models for high and low income countries does not alter the findings for the phh however the impacts of human capital on pollution emission are found to be different for the two groups of countries policies that focus on attracting clean and energy efficient industries through fdi have potential to improve environmental health while enhancing economic growth in latin america
