price discrimination in broadway theater a common thread in the theory literature on price discrimination has been the ambiguous welfare effects for consumers and the rise in profit for firms relative to uniform pricing in this study i resolve the ambiguity for consumers and quantify the benefit for a firm i describe a model of price discrimination that includes both second degree and third degree price discrimination using data from a broadway play i estimate the structural model and conduct various experiments to investigate the implications of alternative pricing policies the observed price discrimination may improve the firm s profit by approximately 5 relative to uniform pricing while the difference for aggregate consumer welfare is negligible also i show that the gain from changing prices in the face of fluctuating demand is small under the observed price discrimination

nonlinear pricing in an oligopoly market the case of specialty coffee firms that use nonlinear pricing may distort product characteristics away from their efficient levels this paper offers the first empirical study of this issue using data from a specialty coffee market i estimate a structural utility model to compute consumers benefits from changing products sizes i then compare the estimated benefits to cost data design distortions are relatively large for products not targeted to the highest demand consumers distortions decrease toward zero with drink size for products with the largest profit margins these results support some of the central predictions from nonlinear pricing theory including no distortion at the top

intensive and extensive margins of exports what can india learn from china we decompose india s export performance in manufactured products during 2000 15 into changes at the intensive and extensive margins india s performance along different margins is compared and contrasted with that of china the results show that while china outperforms india at both the margins the gap is particularly wide at the intensive margin decomposition of intensive margin along quantity and price margins shows that chinese products are generally sold cheaper than indian products higher price margin however has not translated into high intensive margin for india due to its abysmally low quantity margin we examine different explanations for china s superior performance relative to india along different margins using a gravity model our results suggest that china s exchange rate policy was not the prime reason for its export success neither do we find that fdi inflows were significant in explaining the export performance gap between them the results show that china s export relationship bias towards high income partner countries holds the key in understanding its superior performance this bias is a natural consequence of china s high degree of specialization in labor intensive activities india by contrast due to an idiosyncratic pattern of specialisation has failed to exploit its export potential in high income countries

price discrimination copyright law and technological innovation evidence from the introduction of dvds u s copyright law effectively prevents direct price discrimination for copyright holders that sell to different markets in response these firms can engage in indirect price discrimination i derive theoretical predictions about the use of indirect price discrimination and i analyze how optimal pricing strategies differ for different products using data on vhs and dvd movie distribution i find that firms pricing choices are consistent with the predictions of theory and that firms use of indirect price discrimination benefits consumers but harms ancillary retailers finally i examine what optimal pricing strategies might look like in a legal environment that permits direct price discrimination

environmental efficiency of investments in renewable energy comparative analysis at macroeconomic level abstract this paper aims to bring into attention the concept of renewable energy investments efficiency and to study one of the three concepts related to it namely environmental efficiency of investments in renewable energy the analysis is undertaken at macroeconomic level for several countries in europe some of them are member states of european union and were observed over the period between 1990 and 2008 the method assumes the study of the econometric models based on kaya identity an equation widely used in studies regarding emissions trends and future emissions scenarios working with time series and cross sectional data a panel data approach is needed indicators like energy intensity co 2 intensity and gross domestic product per capita and per unit of investment are used as they establish a connection between effects and efforts a prerequisite for studying the efficiency a novelty of this research lies in the calculation of environmental efficiency index after an original method proposed by authors the findings of this analysis reveal that there are both countries with high and low environmental efficiency of investments in renewable energy

vertical contracts in the video rental industry a large body of theoretical work has explored the channels through which vertical contracts can induce efficiency improvements however it is also important to study vertical contracts empirically in order to gain insight into the relative size of different types of efficiency gains in this paper i empirically analyse a contractual innovation in the vertically separated video rental industry prior to 1998 video stores obtained inventory from movie distributors using simple linear pricing contracts in 1998 revenuesharing contracts were widely adopted i investigate the effect of the introduction of revenue sharing contracts on firms profits and consumer welfare i analyse a new panel data set of home video retailers that includes information on individual retailers contract and inventory choices as well as rentals and contract terms for 246 movie titles and 6137 retailers in the u s during each week of 1998 and 1999 and the first half of 2000 a structural econometric model of firms behaviour is developed that describes the nature of firms contract choices estimates from this model indicate that both upstream and downstream profits increase by 10 under the revenue sharing contract for popular titles for less popular titles the effects can be even larger i also estimate that consumers benefit when revenue sharing contracts are adopted

price discrimination and retail configuration the hypothesis that price discrimination based on willingness to pay for quality can occur in multifirm markets is confirmed using microdata on gasoline retailing a test that discriminates between price structures associated with discrimination and with cost driven competitive differentials is developed and implemented with controls for variation in outlet and market characteristics a second test based on profitability variation rejects a competitive peak load pricing explanation for the observed price dispersion the data suggest that price discrimination at the retail level adds at least 9 a gallon to the average price of full service gasoline

an empirical study of uniform and differential pricing in the movie theatrical market abstractmovies vary widely in appeal star power cost and other elements and therefore each might be expected to charge a different price multiplexes however typically charge the same price for all movies except for such premium formats as 3d a choice that has puzzled managers and researchers because of data limitations minimal empirical work has directly addressed this issue in hong kong however prices vary both within and across multiplexes using daily ticket prices and attendance by theater and movie the authors empirically examine the potential gains from differentiated movie specific pricing as well as the increasingly common two tier 2d 3d uniform pricing as compared with a full uniform pricing strategy in which a theater charges the same price for all its movies their results show that differential pricing leads to higher profits than the two tier uniform pricing practice but that the improvement is limited in contrast the gains are substantial when compared with the full uni

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

viewpoint sustainability malthus revisited the sustainability debate concerns whether the world will experience stable or improving living standards for the foreseeable future or whether the current trajectory will overtax the natural environment leading to a crash in living standards this paper selec tively reviews relevant research focusing on both ecological concerns and technological progress and asks whether sustainability would be problematic without rapid population growth i suggest that continued demographic transition to lower fertility is the primary requirement for achieving sustainable development this is effectively a modern transla tion of malthus 1798 the paper also discusses the role of the malthusian cycle in human evolution jel classification q56 j10

eco efficiency assessment of eu manufacturing sectors combining input output tables and data envelopment analysis following production and consumption based accounting approaches abstract assessing the footprint of anthropogenic activities has become particularly challenging in today s globalized markets where a large number of economic transactions taking place across the globe need to be disentangled before the most critical sectors are identified in this work we present an approach to quantify the eco efficiency of economic activities that combines multi regional environmentally extended input output tables and data envelopment analysis we employ this method to assess the european union manufacturing sectors in terms of three inputs global warming potential potential acidifying equivalent and tropospheric ozone forming potential and one output economic wealth following both production and consumption based accounting approaches our approach classifies economic sectors as efficient and inefficient and for the latter it provides improvement targets that if attained would make them efficient we find that there is a significant mismatch at the sectorial level between both accounting schemes each providing complementary information for policy making in the production based case targets allow identifying sectors and pollutants requiring more stringent regulations and or higher investments in cleaner technologies conversely the consumption based accounting allows identifying the ultimate sources of impact an insight that can assist in the selection of alternative cleaner suppliers via eco labelling of products services and proper taxation schemes

retail competition and the dynamics of demand for tied goods we present a demand system for tied goods incorporating dynamics arising from the tied nature of the products and the stockpiling induced by storability and durability we accommodate competition across tied good systems and competing downstream retail formats by endogenizing the retail format at which consumers choose to stockpile inventory this facilitates measurement of long run retail substitution effects and yields estimates of complementarities within and substitution across competing systems of tied goods we present an empirical application to an archetypal tied goods category razors and blades we discuss the implications of measured effects for manufacturer pricing when selling the tied products through an oligopolistic downstream retail channel and assess the extent to which retail substitution reduces channel conflict

india and china contrasts in economic liberalization abstract it is argued that in both india and china despite some important differences 1 a similar cultural and political imperatives led to similar systems of dirigisme and economic outcomes with the chinese growth higher than the indian because of higher investment 2 b crises engendered by their dirigiste regimes impelled reform 3 c their attempts to replace the plan by the market have striking similarities but 4 d ultimately because of continuing atavistic attitudes to toward trade and commerce the reforms remain insecure

intertemporal price discrimination with complementary products e books and e readers this paper studies intertemporal price discrimination ipd with complementary products in the context of e readers and e books using individual level data 2008 2012 i estimate a dynamic demand

mergers with differentiated products the case of the ready to eat cereal industry traditional merger analysis is difficult to implement when evaluating mergers in industries with differentiated products i discuss an alternative which consists of demand estimation and the use of a model of postmerger conduct to simulate the competitive effects of a merger i estimate a brand level demand system for ready to eat cereal using supermarket scanner data and use the estimates to 1 recover marginal costs 2 simulate postmerger price equilibria and 3 compute welfare effects under a variety of assumptions the methodology is applied to five mergers two of which occurred and for which i compare predicted to actual outcomes

the lmdi approach to decomposition analysis a practical guide in a recent study ang energy policy 32 2004 compared various index decomposition analysis methods and concluded that the logarithmic mean divisia index method is the preferred method since the literature on the method tends to be either too technical or specific for most potential users this paper provides a practical guide that includes the general formulation process summary tables for easy reference and examples

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

the effect of ownership structure on prices in geographically differentiated industries i analyze how ownership structure and market geography jointly influence fast food prices i estimate a model of demand and supply that accounts for the market geography and run counterfactual experiments that demonstrate how mergers affect prices i find that the impact of mergers can be large that this impact decreases as the merging outlets are farther apart that mergers among market leaders generally increase prices more than mergers among weaker firms and that mergers can increase prices even if the outlets are so far apart that neither outleti s presence affects prices at the other before the merger

swedish co2 emissions 1993 2006 an application of decomposition analysis and some methodological insights this study undertakes a decomposition analysis to identify the drivers of carbon dioxide emissions change in the swedish business and industry sectors 1993 2006 on aggregate energy intensity decreased but this does not seem to have been very important for reducing emissions rather fuel substitution seems to have been more important which is in line with findings from the decomposition literature on sweden however at the sectoral level we find no clear pattern of the effect of fuel substitution and energy intensity on emissions we also draw some methodological conclusions decomposition analysis should be undertaken at the most disaggregate level possible assessing decomposition results by summing results over several time periods leads to biased results and decomposition analysis should not be based only on some initial and final years of a long time period furthermore we address the problem of double counting energy flows in decomposition analysis of aggregate effects when the energy sector is included and point out potential problems related to output measured in monetary terms

empirical relevance of the hillman condition for revealed comparative advantage 10 stylized facts the theoretically necessary and sufficient condition for the correspondence between revealed comparative advantage and pre trade relative prices derived by hillman 1980 is analysed empirically for virtually all countries of the world over an extended period of time this yields 10 stylized facts including that i violations of the hillman condition are small as a share of the number of observations but substantial as a share of the value of world exports ii violations occur relatively frequently in the period 1970 1984 and more rarely in the period 1985 1997 and iii violations occur foremost in primary product and natural resource intensive sectors and for countries in africa the middle east latin america and central and eastern europe an additional bonus of verifying the hillman condition in empirical research is its ability to identify erroneously classified trade flows

china s foreign trade and climate change a case study of co2 emissions abstract the globalization of trade has numerous environmental implications trade creates a mechanism for consumers to shift environmental pollution associated with their consumption to other countries carbon leakage exerts great influences on international trade and economy applying an input output approach the paper estimates the amount of carbon dioxide co2 embodied in china s foreign trade during 1997 2007 it is found that 10 03 26 54 of china s annual co2 emissions are produced during the manufacture of export goods destined for foreign consumers while the co2 emissions embodied in china s imports accounted for only 4 40 1997 and 9 05 2007 of that we also estimate that the rest of world avoided emitting 150 18 mt co2 in 1997 increasing to 593 mt in 2007 as a result of importing goods from china rather than manufacturing the same type and quantity of goods domestically during 1997 2007 the net additional global co2 emissions resulting from china s exports were 4894 mt then the paper divides the trade embodied emissions into scale composition and technical effect it was found that scale and composition effect increased the co2 emissions embodied in trade while the technical effect offset a small part of them finally its mechanism and policy implications are presented

risk preferences and demand drivers of extended warranties we disentangle and study the relative importance of different risk preferences in explaining extended warranty purchases and the high premia paid for them empirical and behavioral research on insurance is at odds with whether diminishing returns curvature of the utility function or loss aversion and nonlinear probability weighting lead to observed consumer behavior this lack of consensus is primarily due to the inability of standard choice data to separate different risk preferences and the consequent need to rely on strong parametric assumptions we design two conjoint studies consistent with simultaneous and sequential decision making with choices about washing machines and extended warranties where subjects are given failure probabilities and repair costs using stated choice data from the surveys we can nonparametrically identify product and risk preferences we find that loss aversion is significantly more important than curvature and probability weights in explaining extended warranty choices importantly failure to decompose risk averse behavior into that arising from curvature loss aversion and probability weighting leads to lower washer prices and profits these findings are robust to alternate reference point assumptions we rationalize the premia paid for warranties by exploring retailer incentives to price discriminate and test the theory on complementary goods pricing finally based on counterfactual analysis forcing separate retailers to sell washers and extended warranties is not necessarily welfare enhancing as cited in the media and previous literature

package size and price discrimination in the paper towel market abstract estimates from a structural model of consumer behavior and firm conduct are used to decompose the extent to which quantity discounts for paper towels are consistent with second degree price discrimination as opposed to cost differences across sizes counterfactual exercises assuming that firms offer only one package size or charge uniform prices across sizes indicate that competition in the multi roll package size segment results in increased consumer surplus and lower prices for all consumers

management accounting approach to analyse energy related co2 emission a variance analysis study of top 10 emitters of the world the paper undertakes a decomposition study of carbon dioxide emission of the top ten emitting countries over the period 1980 2007 using variance analysis method with the objectives of examining the relative importance of the major determining factors the role of energy structure and impact of liberalisation on emission and exploring the possibilities of arresting emission with simultaneous rise in population and income the major findings indicate that although rising income and population are the main driving forces they are neither necessary nor sufficient for increasing emission rather energy structure and emission intensities are the crucial determinants pointing towards the fact that a country with higher income and population with proper energy policy may be a low emitter and vice versa since modern energy intensive production limits the scope of reduction in total energy use it is necessary to decouple the quantum of energy use from emission through technological upgradation the results indicate that liberalisation resulted in higher emission the paper attempts to illustrate the required adjustments in energy structure and suggests necessary policy prescriptions

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

silverscreener a modeling approach to movie screens management managing the allocation of shelf space for new products is a problem of significant importance for retailers the problem is particularly complex for exhibitors the retailers in the motion picture supply chain because they face dynamic challenges given the short life cycles of movies the changing level of demand over time the scarcity of shelf space and the complex revenue sharing contract between the exhibitor and the distributor in the face of this complexity the aim of current research is to provide a structure for analyzing management problems of exhibitors in the movie industry using a mathematical programming approach and a fast but readily accessible algorithm we propose a decision support model silverscreener whose aim is to help exhibitors make effective and timely decisions regarding theater screens management the major objective is to help select and schedule movies for a multiple screens theater over a fixed planning horizon in such a way that the exhibitor s cumulative profit is maximized by treating the multiple screens as parallel machines and the movies as jobs we provide an analogy of the current problem to the parallel machine scheduling problem we formulate the resulting problem as an integer program we depart from the typical parallel machine scheduling problems by introducing the time indexed formulation that is particularly useful for solving the current problem an important distinction between the current problem and typical machine scheduling problems is that the present approach allows for the choice of which movies to play typically in machine scheduling all jobs have to be scheduled we provide various analyses of normative versus actual decision making based on publicly available data the developed model is readily implementable and appears to lead to improved profitability in different comparative cases through sensitivity analysis we demonstrate that the above results are robust to variations in various parameters of the problem the main findings and insights from the normative policy suggest the following 1 based on silverscreener s recommendations the exhibitor can achieve substantially higher cumulative profit 2 the improvement over actual decisions in terms of profitability appears to result from a combination of better selection and scheduling of the movies 3 the general structure of the exhibitor s normative decision is choose fewer right movies and run them longer we propose a two tier integrated application of the model to show how the model can be applied to realistic decisionmaking the first tier involves development of a movie selection plan to help the manager plan an entire season and bid for movies before the start of that season an ex ante revenue prediction scheme is developed based intuitively on a matching of the forthcoming movies with similar movies played in this theater previously if the forthcoming season s scheduling plan can be visualized as a two dimensional week by screen matrix then that matrix contains only empty cells before the first tier after a bid plan is developed the exhibitor can fill some of those empty cells the remaining empty cells represent slots which can be decided during the season by either extending movies the exhibitor booked before the season or by scheduling other movies which may become available later in the season this motivates the second tier adaptive scheduling approach of the integrated approach the second tier helps the exhibitor in weekly decision making during the season this application involves rolling and updating data from one time window to another the approaches followed in the two tiers of the integrated application are quite general in that they can incorporate a sophisticated demand prediction model managerial judgments or a combination of both we also propose an alternative behavioral decision rule heuristic which exemplifies relationship dilemmas in the movie industry this heuristic shows that the exhibitors need to be selective in their choice of movies and may suffer a substantial loss in profitability if they place too much emphasis on accommodating distributors

modeling movie life cycles and market share we examine box office sales in the context of a market share model this is accomplished by developing a combination of a sliding window logit model and a gamma diffusion pattern in a hierarchical bayes framework we show that accounting for the full choice set available every week not only increases the fit of weekly movie sales but also leads to parameter estimates that depict a richer picture of the movie industry we show that movie studios appear to have a good understanding of the products they produce knowing when to support them and when not to we also show that the effect of the number of opening week screens is overestimated in traditional models our research indicates that actors have a direct and directors an indirect effect on consumers movie choice releasing a movie contemporaneously with other movies of the same genre adversely affects box office performance all around releasing a movie against movies of the same motion picture association of america mpaa rating hurts its sales in the beginning but there is a displacement effect which leads to a less severe sales loss in the long run

empirical analysis of metering price discrimination evidence from concession sales at movie theaters prices for goods such as blades for razors ink for printers and concessions at movies are often set well above cost theory has shown that this could yield a profitable price discrimination strategy often termed metering the idea is that a customer s intensity of demand for aftermarket goods e g the concessions provides a meter of how much the customer is willing to pay for the primary good e g admission if this correlation in tastes for the two goods is positive a high price on the aftermarket good allows firms to extract a greater total price admissions plus concessions from higher type customers this paper develops a simple aggregate model of discrete continuous demand to motivate how this correlation can be tested using simple regression techniques and readily available firm data model simulations illustrate that the regressions can be used to predict whether aftermarket prices should be above below or equal to their marginal cost we then apply the approach to box office and concession data from a chain of spanish theaters and find that high priced concessions do extract more surplus from customers with a greater willingness to pay for the admission ticket

why india lags behind china and how it can bridge the gap though india has been growing at six per cent annually since the late 1980s it trails behind china which has been growing at ten per cent per annum since 1981 the single most important factor explaining this difference is the relatively poor performance of indian industry whereas the share of industry in china s gdp rose from 42 per cent in 1991 to 51 per cent in 2001 it remained virtually stagnant in india by contrast services grew rapidly in india expanding from 42 per cent in 1991 to 48 per cent in 2001 with the information technology sector less than two per cent of the gdp services growth was largely in the informal sector approximately 77 per cent of india s workers live in rural areas to bring a large chunk of this workforce into the modern sector india must achieve a much higher growth in the traditional unskilled labour intensive industry growth in the information technology sector gives india an extra lever but cannot be the main engine of transformation therefore the right approach is to walk on two legs traditional labour intensive industry and the modern it industry both legs need strengthening through further reforms the paper suggests four specific reforms three for industry and one for it necessary to achieve the transformation to a modern economy

seasonality in the u s motion picture industry the observed seasonality of box office revenues reflects both seasonality in underlying demand for movies and seasonality in the number and quality of available movies i separately identify these aspects by estimating weekly demand for movies using movie fixed effects a long panel of movies weekly revenues and restrictions on their decay pattern i find that the estimated seasonality in underlying demand is much smaller and slightly different from the observed seasonality of sales the biggest movies are released at times when demand is highest amplifying the underlying seasonality price rigidities in the industry may facilitate this amplification effect

a model of add on pricing this paper examines competitive price discrimination with horizontal and vertical taste differences consumers with higher valuations for quality are assumed to have stronger brand preferences two models are considered a standard competitive price discrimination model in which consumers observe all prices and an add on pricing game in which add on prices are naturally unobserved and firms may advertise a base good at a low price in hopes of selling add ons at high unadvertised prices in the standard game price discrimination is self reinforcing the model sometimes has both equilibria in which the firms practice price discrimination and equilibria in which they do not the analysis of the add on pricing game focuses on the chicago school argument that profits earned on add ons will be competed away via lower prices for advertised goods a conclusion is that add on practices can raise equilibrium profits by creating an adverse selection problem that makes price cutting unappealing although profitable when jointly adopted using add on pricing is not individually rational in a simple extension with endogenous advertising practices and costless advertising several models that could account for add on pricing are discussed

demand and supply dynamics for sequentially released products in international markets the case of motion pictures we develop an econometric model to study a setting in which a new product is launched first in its domestic market and only at a later stage in foreign markets and where the product s performance demand and availability supply are highly interdependent over time within and across markets integrating literature on international diffusion success breeds success trends and the theatrical motion picture industry the focus of the empirical analysis we develop a dynamic simultanenous equations model of the drivers and interrelationship of the behavior of consumers audiences and retailers exhibitors our findings emphasize the importance of considering the endogeneity and simultaneity of audience and exhibitor behavior and challenge conventional wisdom on the determinants of box office performance which is predominantly based on modeling frameworks that fail to account for the interdependence of performance and availability specifically we find that variables such as movie attributes and advertising expenditures which are usually assumed to influence audiences directly mostly influence revenuesindirectly namely through their impact on exhibitors screen allocations in addition consistent with the idea that the buzz for a movie is perishable we find that the longer is the time lag between releases the weaker is the relationship between domestic and foreign market performance an effect mostly driven by foreign exhibitors screen allocations
