how durable should durable products be made under different scenarios of technological advance abstract this paper addresses the question of how durable or reliable manufacturers of durable goods should make their products essentially consumers are likely willing to pay more for a more durable product yet increased durability depresses replacement demand we gain insight into this trade off by developing analytical models of the interplay between consumers and a monopolist manufacturer of durable goods we start this research from the base model that assumes symmetric information between the manufacturer and consumers and no technological advance we then extend it to more general models in which these assumptions are relaxed interesting managerial insights are obtained which explain well some realistic cases observed in practice 1 when the technology advances at a given non negative rate it is always optimal for the manufacturer to motivate consumers to replace the existing durable goods by using a buy back offer before the end of the life of the product 2 faster technological advance does not always bring quicker product replacements under some circumstances it might be optimal for manufacturers to extend the replacement cycle of the product and increase its durability when the technology advances more quickly and 3 when the rate of the technological advance is uncertain and is not directly observable by consumers consumers are willing to pay more than when the technological advance rate is known and constant

macroprudential policies capital flows and the structure of the banking sector abstract using a large sample of advanced and emerging market economies over the period 1999 2012 we examine the effectiveness of macroprudential policies mpps in managing cross border bank flows conditioning on the structure of the banking sector in the mpp implementing country we find that higher regulatory quality and a higher credit to deposit ratio increase the effectiveness of mpps while a higher cost to income ratio has the opposite effect if all three financial variables are evaluated at the median the marginal effect of our preferred mpp measure leads to a reduction of international bank inflows in percent of gdp by around half a percentage point and is only marginally significant however when the more enhanced 25th 10th percentiles of their respective distributions are considered we observe as a response to the same mpp measure a reduction of bank inflows by 3 44 5 39 percentage points that is highly statistically and economically significant additionally we find that the structure of the domestic banking sector determines spillovers from mpps across asset classes while spillovers from mpps across countries are a function of banking sector conditions both at home and abroad

the role and growth of new car leasing theory and evidence abstractthere has been substantial growth in rates of new car leasing over the last few decades building on recent theoretical research we construct a model of the leasing decision in which leasing mitigates adverse selection and reduces transaction costs but moral hazard limits its use in our model the prevalence of leasing is related to new car reliability which suggests that the recent growth in leasing is at least partly due to improvements in new car reliability we use this model to derive testable implications and then conduct an empirical analysis to investigate whether the operation of the new and used car markets is consistent with the predictions of this theoretical approach our empirical results support the theoretical predictions of our model in particular we provide direct evidence that leasing mitigates adverse selection and that an important factor in the growth in new car leasing rates has indeed been the growth of new car reliability

durable goods monopolists durable goods monopolists face special problems because the sale of their products creates a secondhand market not controlled by the monopolist to the extent the monopolist is able to rent his product rather than sell it or to make binding promises about his future production such problems are ameliorated given the inability to do the above the monopolist is led to producing goods less durable than those produced by either competitive firms or monopolist returns a reverse averch johnson result that monopolist sellers may invest less in fixed costs including plant modernization and research and development than would the renters is shown it is also shown that even though sellers have less monopoly power than renters and nondurable goods monopolists it is possible that the seller will cause a greater deadweight loss than the other types of monopolies

dual distribution channels the competition between rental agencies and dealers managerial decisions involving marketing channels are among the most critical that an organization must make part of the reason for this importance is that relationships between manufacturers and their intermediaries usually involve long term commitments that are difficult to change on the other hand in order to respond to the realities of the market place an organization must be ready to adapt its distribution practices sometimes under considerable uncertainty about the long term consequences such a problem faces the u s automobile industry which has led manufacturers to experiment with various channel structures when manufacturers first changed their distribution policies they were clear about the short term effect on sales but were unsure about its longer term impact on profitability in this article we develop a model to analyze the marketing of durable products through multiple channels our analysis suggests that even though it was not apparent at the time manufacturers were indeed behaving optimally when they changed their policies our model provides insights not only to automobile manufacturers but also to practitioners and academics who are interested in understanding the unique problems associated with marketing durable products through multiple channels we develop a two period model by assuming that a single manufacturer markets a durable product through two retailers a rental agency and a dealer the rental agency focuses mainly on renting the product in a daily rental market while the dealer focuses on selling the product to a different set of customers in the sales market to model the development of channels in the u s automobile industry we analyze three different channel structures the first structure a separate channel reflects the state of the industry through most of the 1980s when rental agencies were franchised solely to rent and dealers solely to sell the cars in response to a decrease in overall sales manufacturers encouraged rental agencies to sell their slightly used rental cars in the consumer market resulting in the second structure an overlapping channel dealers did not like this arrangement however and in the next experiment a buyback channel some manufacturers began buying back used rental cars and selling them through dealers in terms of the consumer side of the model we assume that consumers are heterogeneous and have product valuations that are distributed uniformly between a low and a high value in addition they recognize that as the durable depreciates with use its secondhand market value decreases while both sold and rented goods depreciate with use we assume based on an analysis of market prices that sold goods depreciate at a higher rate than rented goods given these different depreciation rates and consumers underlying utility functions we develop the market demand functions in the dealer s and rental agency s markets then for each of the channel structures we solve the intermediaries and manufacturer s problems the main contribution of this article is that it allows us to evaluate the profitability associated with various channel structures for all the players in our analysis the dealer the rental agency and the manufacturer in terms of the intermediaries we find that the overlapping channel is the most profitable structure for the rental agency on the other hand it is the least profitable for the dealer in terms of manufacturer profitability our model suggests that the separate channel is the least profitable and the overlapping channel is the most profitable it is interesting to note that the distribution structure in existence today is more akin to a buyback channel this strikes us as a compromise channel which alleviates dealer concerns with the overlapping channel and yet does not harm rental agencies as much as a separate channel these are surprising results because conventional wisdom has been that the overlapping channel was competing away profits for all players this suggests to us that automobile manufacturers were indeed on the right track when they began experimenting with the structure of their distribution channels

the collapse of purchasing power parities during the 1970 s one of the striking facts concerning the relationship beiveen prices and exchange rates during the 1970 s has been the dismal performance of the predictions of the simple versions of the purchasing power parity doctrine ppp that doctrine in its absolute version states that the equilibrium exchange rate between domestic and foreign currencies equals the ratio of domestic to foreign price levels the relative version of the doctrine relates equilibrium changes in exchange rates to changes in the ratio of domestic to foreign prices during the 1970 s short run changes in exchange rates bore little relationship to short run differentials in national inflation rates and frequently divergences from purchasing power parities have been cumulative this paper reviews and analyzes the empirical record of exchange rates and prices during the 1970 s and the analysis is based on the experience of the dollar pound the dollar frecch franc and the dollar dm exchange rates section 2 presents the evidence on ppp during the 1970 s and contrasts it with the evidence from the 1920 s a period during which the doctrine held up reasonably well this analysis is relevant for assessing whether the flexible exchange rate system was successful in providing national economies with an added degree of insulation from foreign shocks and whether it provided policymakers with an added instrument for the conduct of macroeconomic policy the evidence regarding devia tions from purchasing power parities is also relevant for determining whether there is a case for managed float section 3 attempts to explain what went wrong with

foundations of dynamic monopoly and the coase conjecture subgame perfect equilibria are characterized for a market in which the seller quotes a price each period assume zero costs positive interest rate continuum of buyers and some technical conditions if buyers valuations are positive then equilibrium is unique buyers strategies are stationary and the price sequence is determinant along the equilibrium path but possibly randomized elsewhere otherwise a continuum of stationary equilibria can exist but at most one with analytic strategies coase s conjecture is verified for stationary strategies reducing the period length drives all prices to zero or the least valuation connections to bargaining models are described journal qf economic literature classification

competition in durable goods markets the strategic consequences of leasing and selling in marketing durable goods manufacturers use varying degrees of leasing and selling to consumers e g cars photo copiers personal computers airplanes etc the question that this raises is whether the distinction between leases and sales is simply one of price or whether the proportion of leases and sales effects a firm s ability to compete in the market in this paper we use two approaches to argue that leasing and selling create strategic consequences that extend beyond prices first we develop a stylized theoretical model that shows that the optimal proportion of leases and sales depends on the competitiveness of the market and on the inherent reliability of the firm s product and second we find support for the implications of our theoretical model with data from the automobile industry the u s automobile industry has seen a large increase in leasing over the last five years however the extent to which leasing has been embraced varies widely across manufacturers for example in 1993 the sport utility segment had the following lease percentages ford explorer 29 jeep grand cherokee 24 toyota 4 runner 11 and chevrolet blazer 9 in addition manufacturers often vary lease percentages across models for example in 1993 ford leased 22 of its crown victoria model 35 of its taurus model and 42 of its probe model a popular argument for why we see these differences is that higher priced cars are leased more often because leasing makes them more affordable however this rationale is not compelling in the face of our data for example the ford probe was priced significantly lower than the crown victoria and yet it was leased almost twice as often to develop a better understanding of why we observe differences in the proportion of leasing we develop a two period model of a duopoly in which each manufacturer chooses its optimal quantity and the fraction of units it wants to lease we find that in equilibrium neither firm leases all its units either they use a mix of leasing and selling or they use only selling our analysis suggests that the fraction of leased cars decreases as the manufacturers products become more similar and the competition between them increases the intuition for this result is that a higher fraction of leases puts the firm at a competitive disadvantage in the future this occurs because unlike firms that sell their product firms that lease are at a price disadvantage another important finding in this paper is that the extent of leasing chosen by a manufacturer depends on the reliability of its product in particular all else being equal the lower a product s reliability the lower its proportion of leases within the context of the automobile industry this suggests that more expensive cars may be leased more often because they are of higher quality and not necessarily because they are more expensive finally we test the implications of our theoretical model with data from the u s automobile market in particular for 1993 model year cars we develop a measure of reliability using data from consumer reports in addition we develop a measure of the extent of competition in each segment of the automobile market we support our hypotheses by finding that the extent to which a car model is leased depends strongly on its predicted reliability and on the competitive intensity within the segment

on credible delegation by oligopolists a discussion of distribution channel management several papers in the recent marketing literature have suggested that delegation in distribution e g the use of independent middlemen helps manufacturers to precommit strategically to profit enhancing competitive actions further the literature suggests that the profitability of such actions depends on market structure we challenge these conclusions here this is done in two steps first we perform an analysis of the entire class of models which have been used in the literature using internally consistent assumptions about market structure and contracting the only subgame perfect equilibrium is one in which all distribution channels have infinitely many levels of delegation obviously this is not what we see in the real world next we relax a key hidden assumption namely that all intra channel agreements are observable to competitors without this assumption the usual results unravel unless channel members can offer credible guarantees that unobservable agreements do not exist the strategic effects of delegation disappear since these guarantees are virtually impossible to maintain credibly we would expect to reject the hypothesis in the earlier literature relating channel structure to competition in an empirical study controlling for observability we conclude that mechanisms other than strategic ones must be responsible for the existence of delegated channels and make some suggestions about promising avenues for future theory research in channel structure

floating exchange rates in peru 1950 1954 abstract three potentially complementary models are tested in an effort to capture the fundamentals that underlaid the market s determination of peru s floating exchange rate through the period 1950 1954 the first is an expectational purchasing power parity ppp model which maintains that asset market forces were driving the exchange rate to its perceived ppp level the second is a flexible price monetary model and the thrid is a model along the lines described by tsiang 1957 which emphasizes world prices for peruvian exports as a fundamental determinant i find that the expectational ppp model not only dominates the others but also fits quite well

bertrand supertraps we study oligopoly price competition between multiproduct firms firms whose products interact in the profit function specifically we focus on the impact of intrafirm product interactions on the level of equilibrium profits this impact may be decomposed in two different ways a a direct effect keeping the competitors actions fixed plus a strategic effect i e through the competitors actions or alternatively b a competitive advantage effect change in firmi only plus an imitation effect change in all other firms we derive conditions such that a the strategic effect more than outweighs the direct effect and conditions such that b the imitation effect more than outweighs the competitive advantage effect bertrand supertraps for example an increase in the degree of economies of scope would increase profits if prices were fixed or if the change were limited to firmi s cost function however if all firms increase the degree of economies of scope then all firms receive lower profits a variety of other applications is considered including learning curves core competencies demand synergies systems competition compatibility bundling network effects switching costs durable goods long term contracts

an economic theory of planned obsolescence planned obsolescence is the production of goods with uneconomically short useful lives so that customers will have to make repeat purchases however rational customers will pay for only the present value of the future services of a product therefore profit maximization seemingly implies producing any given flow of services as cheaply as possible with production involving efficient useful lives this paper shows why this analysis is incomplete and therefore incorrect monopolists are shown to desire uneconomically short useful lives for their goods oligopolists have the monopolist s incentive for short lives as well as a second incentive that may either increase or decrease their chosen durability however oligopolists can generally gain by colluding to reduce durability and increase rentals relative to sales some evidence is presented that appears to be generally consistent with the predictions of the theory

improving channel coordination through franchising in this paper we explore the role of franchising arrangements in improving coordination between channel members in particular we focus on two elements of the franchising contract namely the royalty structure and the monitoring technology we begin with a simple analysis where a manufacturer distributes its product through a retailer and the retail demand is affected by the retail price and the service provided by the retailer in this context we show that neither royalty payments nor monitoring are needed for full coordination we then extend the model to allow for free riding by franchisees and show that although monitoring helps affect the behavior of the franchisees royalty payments are still unnecessary to coordinate the activities of the franchisor and the franchisees finally we show that in environments where factors affecting retail sales are controlled by both the franchisor and the franchisee royalty payments provide the necessary incentives for the franchisor while monitoring systems are used to ensure that franchisees also behave in the best interest of the channel our general results are found to be consistent with those in brickley and dark 1987 and norton 1988 who conclude that franchising is affected by principal agent problems our theory finds special support in the work of lafontaine 1988 where it is concluded that the incidence of franchising is related to cost of monitoring and the importance of franchisor investments

concurrent renting and selling in a durable goods monopoly under threat of entry this article analyzes the choice of contract sales or rental of a durable goods monopolist facing a threat of future entry although in the absence of such a threat a monopolist would prefer to rent his entire output we show that the threat of entry alters that preference there is an optimal preentry contract mix involving both rental and sales if both firms behave as cournot duopolists after entry the optimal choice of preentry contracts enables the erstwhile monopolist to gain the same profits as he would if he behaved as a von stackelberg leader

competition and collusion in the american automobile industry the 1955 price war movements in total quantity and in quality adjusted price suggest a supply side shock in the american automobile market in 1955 this paper tests the hypothesis that the shock was a transitory change in industry conduct a price war the key ingredients of the test are alternative equilibrium models of oligopoly under product differentiation in nonnested cox tests of hypotheses a collusive solution is sustained in 1954 and in 1956 while a competitive solution holds in 1955 the result does not appear to be an artifact since it is robust in tests against alternative specifications copyright 1987 by blackwell publishing ltd

an industry equilibrium analysis of downstream vertical integration this paper investigates the effect of product substitutability on nash equilibrium distribution structures in a duopoly where each manufacturer distributes its goods through a single exclusive retailer which may be either a franchised outlet or a factory store static linear demand and cost functions are assumed and a number of rules about players expectations of competitors behavior are examined it is found that for most specifications product substitutability does influence the equilibrium distribution structure for low degrees of substitutability each manufacturer will distribute its product through a company store for more highly competitive goods manufacturers will be more likely to use a decentralized distribution system this article was originally published in marketing science volume 2 issue 2 pages 161 191 in 1983

durable products time inconsistency and lock in many durable products cannot be used without a contingent consumable product e g printers require ink ipods require songs razors require blades etc for such products manufacturers may be able to lock in consumers by making their products incompatible with consumables that are produced by other firms we examine the effectiveness of such a strategy in the presence of strategic consumers who anticipate the future prices of both the durable product and the contingent consumable under a lock in strategy the manufacturer has pricing power over the contingent consumable which she can use to extract additional rents from higher valuation consumers but such pricing power may also reduce consumers willingness to pay for the durable because it subjects them to being held up with higher consumables prices in the future restricting our attention to linear pricing policies we find that if the manufacturer can commit to shutting down production of her durable after an initial one time sale then competition from another consumable of an appropriately degraded level of quality can benefit the manufacturer by mitigating consumers fears of being held up on the other hand when the manufacturer cannot commit to shutting down production of her durable then her own output of additional durables gives her an incentive to keep consumables prices low and competition in the consumables market is less beneficial this paper was accepted by pradeep chintagunta and preyas desai special issue editors this paper was accepted by pradeep chintagunta and preyas desai special issue editors

pricing information goods a strategic analysis of the selling and pay per use mechanisms we analyze two pricing mechanisms for information goods these mechanisms are selling where up front payment allows unrestricted use and pay per use where payments are tailored to use we analytically model a market where consumers differ in use frequency and where use on a pay per use basis invokes a psychological cost associated with the well known ticking meter effect we demonstrate that pay per use yields higher profits in a monopoly provided the associated psychological cost is low in a duopoly one firm uses selling and the other uses pay per use here in contrast to the monopoly selling yields higher profits than pay per use we demonstrate that surprisingly the profits of both duopolists can increase as the psychological cost associated with pay per use increases next we show that uncertainty in consumer use frequency does not affect pay per use in a monopoly but lowers profits from selling in a duopoly both the seller and the pay per use provider obtain lower profits when use frequency is uncertain we also analyze how pricing mechanism performance is affected if the firms cannot commit to prices if the pay per use provider offers a two part tariff and if consumers are risk averse

durable goods leasing in the presence of exporting used products to an international secondary market abstract with the rapid growth of global trade used durable goods from wealthy countries increasingly find their way into the secondary market of less wealthy countries exporting used products to a physically separate market not only removes cannibalization for new products at home but also fetches additional revenue in this paper we investigate the implications of exporting used products to international secondary markets in the durable goods industry we find that such a practice may significantly stimulate new product lease on the home market an effect in which the market attractiveness and product quality are mutually reinforcing we discover that removing cannibalization pressure is more of a priority than generating additional revenue while exporting used products if the export is carried out by an agent who exports used products bought from oem original equipment manufacturer we observe the disadvantage of double marginalization in a channel structure which slows down export and causes quantity distortion and also reduces the effectiveness of government stimulus however if the agent and oem set export price based supply and demand equilibrium this reduces the quantity distortion one special characteristic of used products trade across borders is the involvement of governments on both sides of the border the government measures include penalties imposed on aging durable goods and trade barriers we find that legislation of penalizing used products on the domestic market can stimulate export but it does not have an intended effect of stimulating new products produced at home the channel structure worsens the problem

durable good monopolies with rational expectations and replacement sales a monopoly producer of a durable good is examined under the previously uninvoked assumption that the good depreciates and hence that replacement sales must occur if a fixed stock of the good is to be maintained we find two ways in which the no depreciation result that the monopoly will always at least eventually produce a stock equal to that produced by a competitive market may not hold if the length of the trading period is nonzero the limiting stock produced by the firm will be lower than the competitive stock to ensure the profitability of future replacement sales if the firm is able to constrain its production capacity it may choose a constraint that always binds in the sense that it will be impossible for the firm to achieve a stock equal to the competitive stock

a dynamic model of entry and exit in a growing industry the potential demand in a new industry evolves over time demand is initially low but advertising by the industry s early entrants can speed up demand growth however there is intrinsic uncertainty of the demand level in each period and uncertainty of the demand evolution path which can be affected by the underlying economic environment we construct a dynamic model that features the stochastically and endogenously expanding demand of a new industry and we investigate the optimal entry and exit behavior of firms as the industry evolves we find that firms incentive to enter early depends critically on the cost that early entrants have to pay in developing the market when the cost is high and the benefit spills over to potential entrants firms have an incentive to wait and the probability of entry can increase with the number of incumbents under certain circumstances firms entry strategy is also influenced by the transition of economic states firms are more likely to enter under a state that shows the prospect of demand taking off soon we also find that in the early stage of an industry higher demand uncertainty can induce faster entry

floating exchange rates in less developed countries a monetary analysis of the peruvian experience 1950 54 since the collapse of the bretton woods system in 1973 there has been an increasing discussion concerning the appropriateness of different exchange rate systems for less developed countries ldcs however this discussion has been marked by the absence of empirical analysis on how floating exchange rate systems behave in ldcs the purpose of this paper is to analyze from a monetary perspective the peruvian experience with floating exchange rates during the early l950s a short run version of the simple monetary approach to exchange rate determination is tested using monthly data for 1950 54 the results obtained are quite satisfactory indicating that the monetary view of exchange rate determination provides a useful benchmark for analyzing the behavior of floating exchange rates in developing economies l
