not all price endings are created equal price points and asymmetric price rigidity abstract we document an asymmetry in the rigidity of 9 ending prices relative to non 9 ending prices consumers have difficulty noticing higher prices if they are 9 ending or noticing price increases if the new prices are 9 ending because 9 endings are used as a signal for low prices price setters respond strategically to the consumer heuristic by setting 9 ending prices more often after price increases than after price decreases 9 ending prices therefore remain 9 ending more often after price increases than after price decreases leading to asymmetric rigidity 9 ending prices are more rigid upward than downward these findings hold for both transaction prices and regular prices and for both inflation and no inflation periods

fixed production capacity menu cost and the output inflation relationship this paper analyses the impact of inflation when firms face frictions in both price and quantity adjustments a vast literature examines the consequences of price adjustment costs assuming frictionless quantity adjustments however temporary quantity adjustments may be expensive for example because continual adjustments of the optimal production plant are impossible moreover recent findings suggest that frictions in quantity adjustment may remove the linkage between output and inflation in this paper we show that this is not the case when inflation is anticipated on the contrary a predetermined production capacity may significantly amplify the consequences of price adjustment costs

optimal pricing and return policies for perishable commodities this paper considers the pricing decision faced by a producer of a commodity with a short shelf or demand life a hierarchical model is developed and the results of the single period inventory model are used to examine possible pricing and return policies the paper shows that several such policies currently in effect are suboptimal these include those where the manufacturer offers retailers full credit for all unsold goods or where no returns of unsold goods are permitted the paper also demonstrates that a policy whereby a manufacturer offers retailers full credit for a partial return of goods may achieve channel coordination but that the optimal return allowance will be a function of retailer demand therefore such a policy cannot be optimal in a multi retailer environment it is proven however that a pricing and return policy in which a manufacturer offers retailers a partial credit for all unsold goods can achieve channel coordination in a multi retailer environment this article was originally published in marketing science volume 4 issue 2 pages 166 176 in 1985

adapting prices or quantities in the presence of adjustment costs it is often hypothesized that costs of adjusting both price and quantities may have important implications for the macroeconomic adjustment process not least to nominal shocks we analyse this in an explicit intertemporal general equilibrium model considering the empirically relevant case of fixed costs of adjusting prices and fixed and variable costs of adjusting quantities we find that the presence of both price and quantity adjustment costs changes the response to shocks significantly it is an implication that small shocks do not support the menu cost case but rather both fixed prices and quantities rationing a numerical analysis based on available evidence on adjustment costs is used to illustrate the likelihood that the various adjustment patterns actually arise

interest rate deregulation monetary policy efficacy and rate rigidity abstract this paper examines the effects of interest rate regulation and subsequent deregulation on the efficacy of monetary policy and rigidity of retail bank deposit rates in hong kong using an error correction model we find that interest rate deregulation increases the efficacy of monetary policy by improving the correlation between retail bank deposit rates and market interest rates and increasing the degree of long term pass through for retail bank deposit rates our study also shows that the adjustments in retail bank deposit rates are asymmetric and rigid upwards during the regulated period but tend to be rigid downwards during the deregulated period the spreads between retail bank deposit rates and market rates have also tightened sharply after the removal of interest rate controls

a multivariate cointegrated modelling approach in testing temporal causality between energy consumption real income and prices with an application to two asian ldcs unlike previous studies on the casual relationship between energy consumption and economic growth this paper illustrates how the finding of cointegration i e long term equilibrium relationship between these variables may be used in testing granger causality based on the most recent johansen s multiple cointegration tests preceded by various unit root or nonstationarity tests we test for cointegration between total energy consumption real income and price level of two asian ldcs thailand and sri lanka nonrejection of cointegration between variables rules out granger noncausality and implies at least one way of granger causality either unidirectional or bidirectional secondly by using a dynamic vector error correction model we then analyse the direction of granger causation and hence the within sample grangerexogeneity or endogeneity of each of the variables thirdly the relative strength of the causality is gauged through the dynamic variance decomposition technique by decomposing the total

inflation costly price and quantity adjustments and time spent in the keynesian regime abstract this paper considers a menu cost firm under inflation due to costly quantity adjustments the firm is sometimes in a keynesian regime where sales are demand determined with a positive real interest rate the proportion of time in the keynesian regime is less than the inverse of the absolute value of the average elasticity of demand in that regime

impact of loss aversion on the newsvendor game with product substitution abstract this paper studies a newsvendor game in which two substitutable products are sold by two different retailers newsvendors with loss averse preferences each loss averse retailer facing stochastic customer demand and deterministic substitution rate will make an order quantity decision to maximize his expected utility since product substitution causes two retailers to make decisions in a competitive environment game theory is used to find the retailers optimal order quantities it is shown that under certain conditions there exists a unique nash equilibrium in the newsvendor game under a symmetry assumption each retailer s equilibrium order quantity is decreasing in the loss aversion coefficient and increasing in the substitution rate further if the effect of loss aversion on the order quantity is strong enough to dominate the effect of competition the total inventory level of a decentralized supply chain will be lower than that of a centralized supply chain numerical experiments are conducted to illustrate our results

asymmetric oil shocks and external balances of major oil exporting and importing countries this study investigates the effects of oil price shocks on three measures of oil exporters and oil importers external balances total trade balance oil trade balance and non oil trade balance we employ three second generation heterogeneous linear panel models and one recently developed non linear panel estimation technique that allows for cross sectional dependence with respect to 28 major oil exporting countries an increase in oil prices leads to an improved real oil trade balance although it is detrimental to non oil and total trade balances this finding might be due to the expenditure effect arising from increases in proceeds from oil exports a decrease in oil prices is found to be beneficial for both total and oil trade balances in these oil exporting countries forty major oil importers seem to be increasingly shielded from positive oil shocks over the 1970s and 1980s however they must worry about oil price declines a decline in oil prices has a negative impact on both total and real oil trade balances resulting from increased oil imports in emerging economies hence a decline in oil prices is beneficial to oil exporters due to the quantity effect outweighing the price effect while for oil importers a stable oil price is more desirable than a price decline these results are important to take into account if we are to gain a full understanding on the magnitude of the trade and macroeconomic effects of oil price changes and what the policy responses should be

pricing and the news vendor problem a review with extensions in the newsvendor problem a decision maker facing random demand for a perishable product decides how much of it to stock for a single selling period this simple problem with its intuitively appealing solution is a crucial building block of stochastic inventory theory which comprises a vast literature focusing on operational efficiency typically in this literature market parameters such as demand and selling price are exogenous however incorporating these factors into the mode l can provide an excellent vehicle for examining how operational problems interact with marketing issues to influence decision making at the firm level in this paper we examine an extension of the newsvendor problem in which stocking quantity and selling price are set simultaneously we provide a comprehensive review that synthesizes existing results for the single period problem and develop additional results to enrich the existing knowledge base we also review and develop insight into a dynamic inventory extension of this problem and motivate the applicability of such models

do the new keynesian microfoundations rationalise stabilisation policy systematic monetary policy is analysed in a two period extension of standard static new keynesian models it is shown that countercyclical policies increase the band of inaction of the price setters and that this feedback effect on price rigidity may make such policies self justifying that is the policies themselves cause the fluctuations that they are stabilising moreover countercyclical policies may in general reduce welfare in fact socially optimal policies may very well involve a commitment to enhance shocks

coordinating a decentralized supply chain with customer returns and price dependent stochastic demand using a buyback policy abstract we investigate a decentralized supply chain that consists of a manufacturer and a retailer where the retailer simultaneously determines the retail price and order quantity while experiencing customer returns and price dependent stochastic demand we propose an agreement between the manufacturer and the retailer that includes two buyback prices one for unsold inventory and a second for customer returns and show that this type of easy to implement agreement can achieve perfect supply chain coordination and be a win win for both manufacturer and retailer when a complementary profit sharing agreement is included

elusive persistence wage and price rigidities the new keynesian phillips curve and inflation dynamics abstract we review the main new keynesian inflation equations that have arisen as a result of aggregation from individual firms price rigidities we find that on the whole they cannot account for inflation persistence a key feature of the empirical dynamics of inflation and with important policy implications the only exceptions seem to be when indexation is allowed in price setting or when price stickiness is combined with wage rigidity and staggering

the competitive newsboy we consider a competitive version of the classical newsboy problem in which a firm must choose an inventory or production level for a perishable good with random demand and the optimal solution is a fractile of the demand distribution and investigate the impact of competition upon industry inventory a splitting rule specifies how initial industry demand is allocated among competing firms and how any excess demand is allocated among firms with remaining inventory we examine the relation between equilibrium inventory levels and the splitting rule and provide conditions under which there is a unique equilibrium our most general result is that if all excess demand is reallocated i e there is perfect substitutability then competition never leads to a decrease in industry inventory

convenient prices currency and nominal rigidity theory with evidence from newspaper prices abstract certain items prices are often set to simplify and expedite transactions by coinciding with available monetary units requiring few pieces of money or requiring little change in this sense these prices are more convenient than other proximate prices this paper models a firm that explicitly incorporates convenience into its pricing decisions where convenience is quantified by the number of currency units in a transaction and illustrates the theoretical behaviors that can arise newspaper cover price data empirically support the theory across a broader range of goods and services convenience appears to play a role in effecting above average nominal price rigidity

the role of rare earth prices in renewable energy consumption the actual driver for a renewable energy world abstract this study examines for the first time in the energy issues literature the long run relationship between rare earth prices and the consumption of energy from renewables the study applies standard time series econometric methodologies and monthly data in relevance to regional and income classification groups of countries spanning the period 2004 2016 the empirical findings indicate the presence of a long run relationship between these variables but for certain rare earths and regions the findings survive a multivariate robustness test while they are expected to be of substantial importance for the world community given that a few countries have control of those materials the importance is lying on the need to establish a global green energy environment

asymmetric wholesale pricing theory and evidence asymmetric pricing or asymmetric price adjustment is the phenomenon where prices rise more readily than they fall we offer and provide empirical support for a new theory of asymmetric pricing in wholesale prices wholesale prices may adjust asymmetrically in the small but symmetrically in the large when retailers face cost of price adjustment such retailers will not adjust prices for small changes in their costs manufacturers then see a region of inelastic demand where small wholesale price changes do not translate into commensurate retail price changes the implication is asymmetrica small wholesale price increase is more profitable because manufacturers will not lose customers from higher retail prices yet a small decrease is less profitable because it will not lower retail prices hence there is no extra revenue from greater sales for larger changes this asymmetry in the behavior of wholesale price vanishes as the price adjustment cost is compensated by the increase in retailers revenue resulting from correspondingly large retail price changes we present a formal economic model of a channel with forward looking retailers and cost of price adjustment test the derived propositions on the behavior of manufacturer prices using a large supermarket scanner data set and find that the results are consistent with the predictions of our theory we then discuss the implications for asymmetric pricing channels and cost of price adjustment literatures as well as public policy

optimal inventory decisions for a risk averse retailer when offering layaway abstract layaway allows economically disadvantaged budget constrained consumers to purchase expensive items through amortized payments and nominal program fees as opposed to using high interest financing options such as credit cards and payday loans we consider a risk averse retailer s ordering decisions when offering a layaway program we use the net loss and total loss functions found in the literature to determine a risk averse retailer s optimal order quantity under conditional value at risk cvar we next analyze the effects of the model parameters retailer s risk aversion the market default rate enrollment fee cancellation fee and so on on the optimal order quantity decisions we show that the optimal order quantity depends on different loss functions and different demand distribution functions further we show that as market default rate increases or the retailer becomes more risk averse then a rational retailer will not offer a layaway program

inflation price competition and consumer search technology abstract this paper studies an s s pricing model in the presence of inflation and price competition in search markets i present a model in which consumers search technologies can influence firms price setting price dispersion and the market structure the result obtained shows that although price competition among firms is intensified in markets where consumers search technologies are more efficient price inflation is counter intuitively more likely to increase the monopoly power and stimulate entry of firms in these markets the model also provides new empirical implications for firms price setting behaviors

on sales effort and pricing decisions under alternative risk criteria abstract in the literature different risk criteria are proposed for risk averse decision making but it is often unclear which risk criteria should be used and what their differences may be this study investigates this problem when a risk averse make to order firm decides its pricing and sales effort two factors affecting demand we consider alternative risk criteria commonly used in the literature namely expected utility theory eut mean variance mv mean semideviation ms value at risk var conditional value at risk cvar and loss aversion la we find that all of these criteria lead to similar qualitative behaviors regarding how risk loss averse decisions deviate from risk neutral ones a particularly interesting result is that the form of demand randomness i e additive or multiplicative can completely reverse the effect of risk loss aversion in certain cases we also find that the risk aversion models i e eut mv ms var and cvar are essentially equivalent in inducing the same set of optimal solutions under adverse market states however loss aversion is a mild version of risk aversion in that the la model can only lead to a subset of the solutions generated by other models these results may not be valid for other applications such as the newsvendor pricing problem so we can conclude that the relationship between alternative risk criteria is case sensitive and should be evaluated more carefully

newsvendor solutions via conditional value at risk minimization abstract in this paper we consider the minimization of the conditional value at risk cvar a most preferable risk measure in financial risk management in the context of the well known single period newsvendor problem which is originally formulated as the maximization of the expected profit or the minimization of the expected cost we show that downside risk measures including the cvar are tractable in the problem due to their convexity and consequently under mild assumptions on the probability distribution of products demand we provide analytical solutions or linear programming lp formulation of the minimization of the cvar measures defined with two different loss functions numerical examples are also exhibited clarifying the difference among the models analyzed in this paper and demonstrating the efficiency of the lp solutions

analysis of the impact of price sensitivity factors on the returns policy in coordinating supply chain this paper analyzes the impact of price sensitivity factors on characteristics of returns policy contracts in a single period product supply chain the contract considers stochastic and price dependent demand we present an analytical model and then use numerical methods with the stackelberg game to identify the contract properties we numerically show that a returns policy indeed improves supply chain performance however the benefits earned from the returns policy under price sensitive and variable demand are different for different supply chain partners first when price sensitivity is high profit of the manufacturer decreases with increase in demand variability second when price sensitivity is sufficiently high and demand variability increases the manufacturer has to surrender part of the profits to the retailer in order to continue sales however even after surrendering part of the profits to the retailer the manufacturer still earns profits that are higher than those available in a wholesale price contract last from the perspective of division of channel profits the retailer is always worse off in case of returns policies than in a wholesale price contract therefore to apply this form of incentive in practice managements should consider the impact of price sensitivity on the returns policy and its performance

price setting with menu cost for multi product firms we model the decisions of a multiproduct firm that faces a fixed menu cost once it is paid the firm can adjust the price of all its products we characterize analytically the steady state firm s decisions in terms of the structural parameters the variability of the flexible prices the curvature of the profit function the size of the menu cost and the number of products sold we provide expressions for the steady state frequency of adjustment the hazard rate of price adjustments and the size distribution of price changes all in terms of the structural parameters we study analytically the impulse response of aggregate prices and output to a monetary shock the size of the output response and its duration both increase with the number of products they more than double as the number of products goes from 1 to 10 quickly converging to the response of taylor s staggered price model

own brand and cross brand retail pass through in this paper we describe the pass through behavior of a major u s supermarket chain for 78 products across 11 categories our data set includes retail prices and wholesale prices for stores in 15 retail price zones for a one year period for the empirical model we use a reduced form approach that focuses directly on equilibrium prices as a function of exogenous supply and demand shifting variables the reduced form approach enables us to identify the theoretical pass through rate without specific assumptions about the form of consumer demand or the conduct of a category pricing manager thus our measurements of pass through are not constrained by specific structure on the underlying economic model the empirical pricing model includes costs of all competing products in the category on the right hand side not only the cost of the focal brand and yields estimates of both own brand and cross brand pass through rates our results provide a rich picture of the retailer s pass through behavior we find that pass through varies substantially across products and across categories own brand pass through rates are on average more than 60 for 9 of 11 categories a finding that is at odds with the claims of manufacturers about retailers in general importantly we find substantial evidence of cross brand pass through effects indicating that retail prices of competing products are adjusted in response to a change in the wholesale price of any given product in the category we find that cross brand pass through rates are both positive and negative we explore determinants of own brand and cross brand pass through rates and find strong evidence in multiple categories of asymmetric retailer response to trade promotions on large versus small brands for example brands with larger market shares and brands that contribute more to retailer profits in the category receive higher pass through we also find that trade promotions on large brands are less likely than small brands to generate positive cross brand pass through i e induce the retailer to reduce the retail price of competing smaller products on the other hand small share brands are disadvantaged along three dimensions trade promotions on small brands receive low own brand pass through and generate positive cross brand pass through for larger competing brands moreover small share brands do not receive positive cross pass through from trade promotions on these larger competitors we also find that store brands are similarly disadvantaged with respect to national brands

inflation and output dynamics with state dependent pricing decisions this paper studies a state dependent pricing model in which firms face a fixed cost of changing their pricing plans a pricing plan specifies an entire sequence of time varying future prices allowing firms to choose a pricing plan rather than a single price generates inflation inertia in the response of the economy to small changes in the growth rate of money allowing firms to choose when to change their pricing plan generates a non linear response of inflation and output to small and large changes in the money growth rate the non linear solution method also reveals that the model generates an asymmetric response of output and inflation to monetary expansions and contractions

the risk averse newsvendor problem with random capacity abstract we study the effect of capacity uncertainty on the inventory decisions of a risk averse newsvendor we consider two well known risk criteria namely value at risk var included as a constraint and conditional value at risk cvar for the risk neutral newsvendor we find that the optimal order quantity is not affected by the capacity uncertainty however this result does not hold for the risk averse newsvendor problem specifically we find that capacity uncertainty decreases the order quantity under the cvar criterion under the var constraint capacity uncertainty leads to an order decrease for low confidence levels but to an order increase for high confidence levels this implies that the risk criterion should be carefully selected as it has an important effect on inventory decisions this is shown for the newsvendor problem but is also likely to hold for other inventory control problems that future research can address

the effect of risk aversion on distribution channel contracts implications for return policies the return policy is often used in retailing supply chains however it is controversial in judging their practical value in the literature various theoretical and modeling explanations of why the return policy is used in practice and is preferred by the retailer and manufacturer have been put forth the literature focusing on the channel agents risk attitudes to explain the adoption seems to have led to the conclusion that the two agents preferences for adopting the full return policy over the no return policy are always in conflict and thus the risk attitudes do not explain the adoption of return policy in practice in this paper we reinvestigate this issue we first identify two distinct phases of risk averseness high or low for each of the two agents we show distinct behaviors of how the wholesale price and order size are set in each phase then we show that the full return policy can be preferred over the no return policy by both the agents if both of them are high risk averse this implies that the agents risk attitudes can explain the adoption of return policy this is a new theoretical result which is contrary to the existing understanding in the literature our result highlights the importance and intricacy of channel policies especially when the risk attitudes of agents are considered

efficient supply contracts for fashion goods with forecast updating and two production modes we examine the problem of developing supply contracts that encourage proper coordination of forecast information and production decisions between a manufacturer and distributor of high fashion seasonal products operating in a two mode production environment the first production mode is relatively cheap but requires a long lead time while the second is expensive but offers quick turnaround we focus on contracts of the form w1 w2 b wherewi is the wholesale price offered for production modei andb is a return price offered for items left over at the end of the season we find that such a contract can coordinate the manufacturer and distributor to act in the best interest of the channel the pricing conditions needed to ensure an efficient solution vary depending on the degree of demand forecast improvement between periods and the manufacturer s access to forecast information we also examine whether these conditions ensure a pareto optimal solution with respect to two traditional production settings

renewable and non renewable energy consumption growth nexus evidence from a panel error correction model abstract unlike previous renewable energy consumption growth studies this study examines the relationship between renewable and non renewable energy consumption and economic growth for 80 countries within a multivariate panel framework over the period 1990 2007 the pedroni 1999 2004 heterogeneous panel cointegration test show a long run equilibrium relationship between real gdp renewable energy consumption non renewable energy consumption real gross fixed capital formation and the labor force with the respective coefficient estimates positive and statistically significant there is little difference in the elasticity estimates with respect to renewable and non renewable energy consumption the results from the panel error correction model reveal bidirectional causality between renewable and non renewable energy consumption and economic growth in both the short and long run also there is bidirectional short run causality between renewable and non renewable energy consumption indicative of substitutability between the two energy sources

technical note a risk averse newsvendor model under the cvar criterion the classical risk neutral newsvendor problem is to decide the order quantity that maximizes the one period expected profit in this note we consider a risk averse newsvendor with stochastic price dependent demand we adopt conditional value at risk cvar a risk measure commonly used in finance as the decision criterion the aim of our study is to investigate the optimal pricing and ordering decisions in such a setting for both additive and multiplicative demand models we provide sufficient conditions for the uniqueness and existence of the optimal policy comparative statics show the monotonicity properties and other characteristics of the optimal pricing and ordering decisions we also compare our results with those of the newsvendor with a risk neutral attitude and a general utility function

renewable and non renewable energy consumption and economic activities further evidence from oecd countries this article examines the dynamic relationship between renewable and non renewable energy consumption and industrial output and gdp growth in oecd countries using data over the period of 1980 2011 the panel cointegration technique allowing structural breaks is used for empirical investigation the results show that there is a long term equilibrium relationship among non renewable and renewable energy sources industrial output and economic growth the panel causality analyses show bidirectional causality between industrial output and both renewable and non renewable energy consumption in the short and long run however there is evidence of bidirectional short run relationship between gdp growth and non renewable energy consumption while unidirectional causality between gdp growth and renewable energy consumption these results indicate that oecd economies still remain energy dependent for their industrial output as well as overall economic growth however expansion of renewable energy sources is a viable solution for addressing energy security and climate change issues and gradually substituting renewable to non renewable energy sources could enhance a sustainable energy economy

the loss averse newsvendor model with backordering abstract in this paper we study the optimal order quantity in the loss averse newsvendor model with backordering we first obtain the optimal order quantity to maximize the expected utility to hedge against the risk arising from the uncertainty of market demand we introduce the conditional value at risk cvar measure and derive the optimal order quantity to maximize the cvar objective about utility it is found that the optimal order quantity with the cvar objective is decreasing in the confidence level and thus is smaller than the optimal order quantity to maximize the expected utility it is proved that under the optimal order quantity with the cvar objective the loss averse newsvendor s expected utility is decreasing in the confidence level it further confirms that high risk implies high return and low risk comes with low return

the right to return this article studies the allocation of responsibility for unsold inventory provision for which is made in practically every distribution contract the two extreme cases are the consignment contract which allocates all the burden to the manufacturer and the no return contract in which retailers purchase the merchandise outright and assume responsibility for unsold inventory contract choices are shown to vary across countries industries products and types of transactions the article identifies six main factors affecting this choice optimal inventory policy in a stochastic retail demand environment relative advantage in disposing of the unsold inventory optimal risk allocation incentives to invest in promotions and provide services to increase consumer demand information asymmetry and costs associated with the consignment contract per se several testable implications are presented and the choice of contracts in the publishing industry is shown to be consistent with the predictions of the model

output and welfare effects of inflation with costly price and quantity adjustments there exists by now a burgeoning literature concerned with the consequences of a fixed cost of price adjustment due to this cost a monopolistic firm does not necessarily adjust its price even though the current price deviates from the price that would maximize the firm s current profit as a result the production generally differs from what it would be in the absence of a menu cost with the effect of inflation on the average output and welfare under monopolistic competition being ambiguous and depending in a complicated way on the profit and demand functions 1 however one strong result holds unambiguously for all profit and demand functions at low inflation rates the average output and welfare are above their levels at full price stability where firms charge the static monopoly price 2 the driving force is that discounting makes a firm more concerned with its real profits earlier in a period with a constant nominal price than with its real profits later in the period in fact as the inflation rate approaches zero the firm s initial real price converges to the profit maximizing real price while the terminal real price converges to a smaller real price at low inflation rates therefore a firm s price is most of the time below the price that would maximize the current profit since output and welfare under monopolistic competition are inversely related to price average output and welfare are higher than under full price stability the inevitable conclusion is that the economy benefits from a little bit of inflation a critical assumption underlying this result is that firms can continuously adjust their production to satisfy demand so while the menu cost literature explicitly assumes that there is a small fixed cost incurred at each price adjustment it also implicitly assumes that it is costless to continuously adjust the quantity of output 3 this is however a questionable assumption there is some empirical evidence indicating the existence of a cost of quantity adjustment part of which is fixed in that it does not depend on the size of the adjustment 4 the cost of quantity adjustment stems from the need to rearrange and reorganize the factor inputs for the new level of production and includes managerial time and effort a fixed cost of quantity adjustment rules out any continuous adjustment of the production to satisfy the increasing demand that results from a decreasing real price within a period with a constant nominal price under the reasonable assumption that the menu cost does not exceed the fixed cost of quantity adjustment 5 in an inflationary environment a firm chooses to adjust its nomi

risk aversion in inventory management traditional inventory models focus on risk neutral decision makers i e characterizing replenishment strategies that maximize expected total profit or equivalently minimize expected total cost over a planning horizon in this paper we propose a framework for incorporating risk aversion in multiperiod inventory models as well as multiperiod models that coordinate inventory and pricing strategies we show that the structure of the optimal policy for a decision maker with exponential utility functions is almost identical to the structure of the optimal risk neutral inventory and pricing policies these structural results are extended to models in which the decision maker has access to a partially complete financial market and can hedge its operational risk through trading financial securities computational results demonstrate that the optimal policy is relatively insensitive to small changes in the decision maker s level of risk aversion

more powerful panel data unit root tests with an application to mean reversion in real exchange rates unit root tests seeking mean or trend reversion are frequently applied to panel data we show that more powerful variants of commonly applied tests are readily available moreover power gains persist when the modifications are applied to bootstrap procedures that may be employed when cross correlation of a rather general sort among individual panel members is suspected copyright 2004 john wiley sons ltd

the loss averse newsvendor game abstract this paper extends the standard newsvendor problem based upon risk neutrality to a game setting where multiple newsvendors with loss aversion preferences are competing for inventory from a risk neutral supplier we show that if the supplier allocates the total demand among the newsvendors proportional to their order quantities then there exists a unique nash equilibrium order quantity in this newsvendor game we also find that while the demand stealing effect increases the total order quantity of the newsvendors the loss aversion effect decreases the newsvendors total order quantity and if strong enough may lead to a lower total inventory level of the decentralized supply chain than that of an integrated supply chain

returns policy new model introduction and consumer welfare abstract this paper investigates how economic outcomes differ for new model introduction between two extreme contracts outright sales contract and returns policy contract with full credit under the outright sales contract we show that the retailer s incentive to introduce a new model can lead to a reduction of consumer welfare when the retailer is moderately risk averse the primary conclusion from this study is that the returns policy contract resolves this conflict between firms and consumers and that the supply chain introduces the new model only when consumer surplus from the new model is higher than that from the old model

price stickiness empirical evidence of the menu cost channel abstract a leading explanation in the economic literature is that monetary policy has real effects on the economy because firms incur a cost when changing prices using a unique database of cost and retail price changes we find that variation in menu costs results in up to 13 3 fewer price increases we confirm that these effects are allocative and have a persistent impact on both prices and unit sales we provide evidence that the menu cost channel operates only when cost increases are small in magnitude which is consistent with theory and provides the first empirical evidence of boundary conditions

renewable energy consumption and unemployment evidence from a sample of 80 countries and nonlinear estimates this article contributes to the discussion on the dynamic nexus of renewable energy consumption and unemployment by incorporating nonlinear cointegration and causality analysis using a sample of 80 countries spanning the period 1990 2013 and the advanced generation of unit root cointegration and nonlinear granger causality methodological approaches in panel data we obtain mixed results about the impact of renewable energy consumption on unemployment although the total findings document a positive impact of renewable energy consumption on unemployment disaggregated data across specific regions such as asia and latin america highlight the favourable effect on unemployment implying that the effect of renewable energy consumption on jobs creation depends on the cost of adopting renewable energy technologies and energy efficiencies that seem to vary across the regions under investigation

menu costs posted prices and multiproduct retailers we use a unique store level data set to directly measure menu costs and to study the price change process at a large u s drugstore chain we compare and contrast the magnitude of these measures with similar measures from four large u s supermarket chains we find that 1 the actual magnitude of menu costs as a share of revenues 2 menu costs per price change 3 the frequent use of promotional pricing and 4 the use of weekly pricing rules are similar across both retail formats given that the main common features of these two types of retail formats are that i they both use posted prices and ii both are multiproduct retailers selling a large number of products our findings suggest that the magnitude of the menu cost components we measure and the price change practices we document may be generalizable across retail formats with these two features

manufacturer s return policies and retail competition manufacturers returns policies are a common feature in the distribution of many products the obvious rationale for returns policies is insurance practitioners not surprisingly have a different perspective and view returns as a cost of doing business in this paper we study the strategic effect of returns policies on retail competition and highlight its profitability implications for a manufacturer the setting for our research is the distribution of products with uncertain demand limited shelf lives and retail competition our objective is to provide a better understanding of when manufacturers should adopt returns policies the insights are obtained with a model based on the economics of strategy and decision making under uncertainty we show that when retailing is competitive and there is no uncertainty in demand a returns policy subtly induces retailers to compete more intensely the provision of a returns policy reduces retail prices without affecting wholesale prices thereby reducing retailer margins and improving manufacturer profitability the intuition is that with a returns policy cournot like levels of retail stocks cannot be sustained each retailer will order stocks so that it will not be constrained by stocks and so intensifying retail competition when however demand is uncertain and there is a single retailer a returns policy encourages the retailer to over stock and so decreases upstream manufacturer profits while the provision of a returns policy leads to lower retail margins the optimality of returns policy depends on the overall uncertainty and marginal cost a returns policy reduces the dispersion in retail prices between the high and low states of demand and the range of retail prices in the returns case is contained within the range of retail prices for the no returns case in the general setting when there are competing retailers and demand is uncertain there is a trade off for the manufacturer between the benefits more intense retail competition and the costs excessive stocking of a returns policy we find that a manufacturer should accept returns when the marginal production cost is sufficiently low and demand uncertainty is not too great to validate the results of our theory we conduct an empirical test with data from a major u s retailer the tests confirm our prediction that a returns policy intensifies retail competition and reduces retailer margins our theory and empirical test should interest practitioners and researchers in distribution especially those concerned with managing retail competition

equilibrium returns policies in the presence of supplier competition the pioneering pasternack returns policy model analyzed channel coordination with a single supplier catering to a retailer facing stochastic demand for a perishable product with a fixed price and the model showed that giving partial returns of unsold stock to the retailer is the optimal policy for the entire supply chain the result thus begs the question as to why manufacturers of perishable commodities widely accept full returns of unsold stock as the norm we model the environment as one where two capacity constrained manufacturers compete for shelf space with the same retailer and we show that a complete credit returns policy is in fact the only possible equilibrium of the game our results obviate the need for knowing the exact functional form of the demand distribution in order to compute the returns credit as pasternack s results would require from a retailer s standpoint we establish a simple procurement strategy and show that it is optimal the same game with price only contracting has a pure strategy equilibrium when the supplier capacities are below a threshold value and a mixed strategy equilibrium when the supplier capacities cross this threshold but are still so limited that no single supplier can with certainty supply all the quantity demanded

when should a manufacturer set its direct price and wholesale price in dual channel supply chains abstract applying an observable delay game framework developed in noncooperative game theory we investigate the timing problem concerning when a manufacturer managing dual channel supply chains consisting of a retail channel and a direct channel should post its wholesale price and direct price conventionally operational research models describing dual channel supply chains examine price competition where the retailer and the manufacturer simultaneously determine the retail and direct prices respectively in contrast to this conventional setting our model demonstrates that such simultaneous price competition never arises if the manufacturer and retailer can choose not only the level of the price but also the timing of pricing if the manufacturer sets the direct price after setting the wholesale price to the retailer the retailer accelerates the timing of retail pricing prior to the direct price setting by the manufacturer our findings suggest that the manufacturer should post the direct price before or upon but not after setting the wholesale price for the retailer this upfront posting of the direct price not only constitutes the subgame perfect nash equilibrium of the noncooperative game between channel members but also maximizes the profits for a manufacturer employing multichannel sales strategies

a tale of two rigidities sticky prices in a sticky information environment macroeconomic models with microeconomic foundations allow for comparisons with macro and micro empirical evidence this paper proposes a model wherein firms i acquire information infrequently generating sticky information mankiw and reis 2002 and ii face menu costs producing state dependent sticky prices i estimate parameters via indirect inference and show that under considerable real rigidity sticky prices in a sticky information environment are consistent with micro and macro evidence sticky prices not only help match micro data on price changes size and durations between adjustments they also improve the model s fit with the macro data as embodied in an empirical phillips curve

mean variance analysis of a single supplier and retailer supply chain under a returns policy abstract in the literature most of the supply chain coordinating policies target at improving the supply chain s efficiency in terms of expected cost reduction or expected profit improvement however optimizing the expected performance alone cannot guarantee that the realized performance measure will fall within a small neighborhood of its expected value when the corresponding variance is high moreover it ignores the risk aversion of supply chain members which may affect the achievability of channel coordination as a result we carry out in this paper a mean variance mv analysis of supply chains under a returns policy we first propose an mv formulation for a single supplier single retailer supply chain with a newsvendor type of product the objective of each supply chain decision maker is to maximize the expected profit such that the standard deviation of profit is under the decision maker s control we study both the cases with centralized and decentralized supply chains we illustrate how a returns policy can be applied for managing the supply chains to address the issues such as channel coordination and risk control extensive numerical studies are conducted and managerial findings are proposed

newsvendor problem with clearance pricing abstract the newsvendor nv problem assumes that the salvage clearance price at which the leftover inventory is disposed of is a given parameter of the problem in this paper we relax this assumption and consider the nv problem with the salvage clearance price as a decision variable we have drawn from the literatures on the nv problem and clearance markdown dynamic pricing to develop three stochastic models in this paper in the first model we assume that while the seasonal demand is exogenous and stochastic the end of season demand is endogenous and deterministic the second model extends the first model by assuming that the end of season demand is endogenous and stochastic finally the third model considers that both the seasonal and end of season demands are endogenous and stochastic we have provided solution procedures for solving the stochastic optimization problems we have also performed sensitivity analyses to assess the sensitivity of the optimal expected profit and order quantity to different problem parameters specifically we have found that the optimal expected profit is most sensitive to the variable cost per unit mean seasonal demand and market potential of end of season demand our models will be useful for retailers of products with a short selling season and a short end of season period for clearance sale of leftover inventory such that there is a single replenishment opportunity at the beginning of the season and a single opportunity for setting the salvage price for clearance sale based on the leftover inventory and end of season demand pattern the paper is concluded with possible directions for future research

the real thing nominal price rigidity of the nickel coke 1886 1959 we report that the price of a 6 5 oz coca cola was 5c from 1886 until 1959 thus we are documenting a nominal price rigidity that lasted more than 70 years the case of coca cola is particularly interesting because during the 70 year period there were substantial changes in the soft drink industry as well as two world wars the great depression and numerous regulatory interventions and lawsuits which led to substantial changes in the coca cola market conditions the nickel price of coke nevertheless remained unchanged we find that this unusual rigidity is best explained by 1 a contract between the company and its parent bottlers that encouraged retail price maintenance 2 a single coin vending machine technology which limited the company s price adjustment options due to limited availability and unreliability of the existing flexible price adjustment technologies and 3 a single coin monetary transaction technology which limited the company s price adjustment options due to the customer inconvenience cost we show that these price adjustment costs are of a different nature than the standard menu cost and their estimates exceed the existing estimates by an order of magnitude a possible broader relevance of the nickel coke phenomenon is discussed in the context of nickel and dime stores which were popular in the us in the late 1800s and the early 1900s

nominal rigidities without literal menu costs evidence from e commerce abstract using price data from online book retailers amazon com and barnes and noble com we show that nominal rigidities persist in an environment that is free from literal menu costs menu costs therefore are not the prime reason for nominal rigidities

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

coping with risk management and fill rate in the loss averse newsvendor model abstract in this paper we introduce the cvar conditional value at risk measure to hedge against the risks for the loss averse newsvendor we derive the optimal order quantities for the loss averse newsvendor to maximize the cvar objective of utility with and without the shortage cost respectively it is shown that when shortage cost is not considered an increase in the degree of loss aversion leads to a decrease in the fill rate therefore the newsvendor should strike a balance between the two conflicting targets in selecting the optimal order quantity when the shortage cost is taken into account and sufficiently large it is proved that an increase in the degree of loss aversion leads to an increase in the fill rate to manage both of the two targets the newsvendor should order more items in this case our sensitivity analysis further verifies that high risk implies high return and low risk comes with low return based on the analysis some management insights for the risk management of the loss averse newsvendor are presented

optimal decisions for the loss averse newsvendor problem under cvar abstract most of the existing literature about the newsvendor problem mainly focused on choosing an optimal order quantity to maximize the expected profit of a risk neutral newsvendor however some studies pointed out that in practice managers decisions as to order quantities always deviate from the profit maximization order quantity which is referred to as decision bias in the newsvendor problem then many studies introduced other preferences rather than risk neutrality of the newsvendor to explain such a decision bias this paper thus introduces loss aversion to the research of the newsvendor decision bias we propose a new definition to the loss averse newsvendor problem legacy loss which is defined either as the loss for excess order or the shortage penalty for lost sales when sales time is due the optimal decisions of a loss averse newsvendor are obtained through the following three ways i minimizing the expected legacy loss ii minimizing cvar of legacy loss by combining the cvar measure in risk management iii minimizing the combination of expected legacy loss and cvar of legacy loss and are compared with other existing results besides we present some properties of the optimal decisions as well as relations among them some numerical examples are given to illustrate the obtained results

when little things mean a lot on the inefficiency of item pricing laws abstract item pricing laws ipls require a price tag on every item sold by a retailer we study ipls and assess their efficiency by quantifying their costs and comparing them to previously documented benefits on the cost side we posit that ipls should lead to higher prices because they increase the costs of pricing and price adjustment we test this prediction using data collected from large supermarket chains in the tri state area of new york new jersey and connecticut we find that ipl store prices are higher by about 20 25 per item on average as a control we use data from stores that use electronic shelf labels and find that their prices fall between ipl and no ipl store prices we compare the costs of ipls to existing measures of the benefits and find that the costs are an order of magnitude higher than the upper bound of the estimated benefits

a risk averse competitive newsvendor problem under the cvar criterion abstract we study a risk averse newsvendor problem with quantity competition and price competition under the conditional value at risk cvar criterion we characterize the optimal quantity and pricing decisions under both quantity and price competition for quantity competition we consider two demand splitting rules namely proportional demand allocation and demand reallocation although competition always leads to overstocking interestingly it does not necessarily lead to a profit loss in certain competitive environments such as demand reallocation by avoiding reducing overstocking that results from competition under the risk neutral criterion for price competition we consider both additive and multiplicative demand we find that the order quantity sale price and the expected profit decrease in the degree of risk aversion further both high price sensitivity and competition intensity force decision makers to lower their prices however high price sensitivity always reduces the order quantity while competition can have the opposite effect

buyback contracts with price dependent demands effects of demand uncertainty chapter 2 examines buyback contracts in a supplier retailer supply chain where the retailer faces a price dependent downward sloping demand curve subject to uncertainty compared with classical research a fundamental difference of this research lies in its analytical examination of the effects of demand uncertainty on the applicability of buyback contracts to this end the research seeks to characterize the buyback contract model in terms of only demand uncertainty level with such a new research perspective some new and interesting findings are obtained for such issues as how demand uncertainty level affects the applicability of buyback practice and how to apply this practice to improve supply chain members own interests or the supply chain system s efficiency the research in this chapter demonstrates that the uncertainty level inherent in market demand can be a critical factor influencing the applicability of supply chain contracts as well as the contract s administrative cost cachon 2003 and the uncertainty type marvel and peck 1995

on returns policies with exogenous price we contribute to current research on single period returns policies by making a clear distinction between models in which transfer price is exogenous and models in which one dominant party unilaterally declares a price we compare the equilibrium contracts that result from these two approaches and derive conditions for the equilibrium returns policy to be pareto efficient when transfer price is exogenous our main result is distribution free but we make some interesting observations on channel performance when demand is uniformly distributed

decision stages and asymmetries in regular retail price pass through we study the pass through of wholesale price changes onto regular retail prices using an unusually detailed data set obtained from a major retailer we model pass through as a two stage decision process that reflects both whether as well as how much to change the regular retail price we show that pass through is strongly asymmetric with respect to wholesale price increases versus decreases wholesale price increases are passed through to regular retail prices 70 of the time while wholesale price decreases are passed through only 9 of the time pass through is also asymmetric with respect to the magnitude of the wholesale price change with the magnitude affecting the response to wholesale price increases but not decreases finally we show that covariates such as private label versus national brand 99 cent price endings and the time since the last wholesale price change have a much stronger impact on the first stage of the decision process i e whether to change the regular retail price than on th

price flexibility in channels of distribution evidence from scanner data in this study we empirically examine the extent of price rigidity using a unique store level time series data set consisting of i actual retail transaction prices ii actual wholesale transaction prices which represent both the retailers costs and the prices received by manufacturers and iii a measure of manufacturers costs for 12 goods in two widely used consumer product categories we simultaneously examine the extent of price rigidity for each of the 12 products at both final goods and intermediate goods levels we study two notions of price rigidity employed in the existing literature i the frequency of price changes and ii the response of prices to exogenous cost changes we find that retail prices exhibit remarkable flexibility in terms of both notions of price rigidity i e they change frequently and they seem to respond quickly and fully to cost changes furthermore we find that retail prices respond not just to their direct costs but also to the upstream manufacturers costs which further reinforces the extent of the retail price flexibility at the intermediate goods level of the market in contrast we find relatively more evidence of rigidity in the response of manufacturers prices to cost changes this despite the fact that wholesale prices change frequently and therefore exhibit flexibility according to the first notion of price rigidity

the impacts of the full returns policy on a supply chain with information asymmetry abstract in contrast to the existing return policies literature assuming that information is symmetrical between the manufacturer and the retailer we study the full returns policy s impact on supply chains with information asymmetry we first study the case that the base level of the demand follows a discrete distribution with two states we find that the retailer benefits from the full returns policy in all circumstances while the manufacturer and the supply chain are better off under some conditions we then consider the situation in which the base level of the demand is a type of ar 1 process

note the role of returns policies in pricing and inventory decisions for catalogue goods manufacturers often use returns policies to encourage retailers to stock and price items more aggressively we focus on the effect that such policies have on both a retailer s and a manufacturer s profits when the retailer must commit prior to the selling season to both a stocking quantity and a price at which to sell an item such a commitment is often necessary for retailers who sell primarily through catalogues

a risk tolerance analysis for a joint price differentiation and inventory decisions problem with demand leakage effect abstract price differentiation is a commonly used practice in revenue management rm to improve a firm s profitability however most studies in the literature have considered a risk neutral firm to demonstrate the benefits of price differentiation the main contribution of this paper is in considering several important objectives while determining the optimal product prices and order production quantities for a risk adjusted firm with demand leakage effects in the presence of a price dependent stochastic demand the objectives considered include the maximization of a firm s expected profit and maximizing the probability of exceeding the risk adjusted expected revenue closed form expressions for optimal product prices and production quantities are derived for several of these objectives a numerical study is also presented to calibrate the impact of a firm s risk tolerance and other factors such as demand leakage market demand variability on the firm s profitability and its optimal decision

a note on probability distributions with increasing generalized failure rates distributions with an increasing generalized failure rate igfr have useful applications in pricing and supply chain contracting problems we provide alternative characterizations of the igfr property that lead to simplify verifying whether the igfr condition holds we also relate the limit of the generalized failure rate and the moments of a distribution

monetary transmission via the administered interest rates channel abstract this paper examines the dynamics of administered interest rate changes in response to changes in the benchmark money market rate in singapore our results show that the administered rates adjustment speed differs across both financial institutions and financial products the financial institutions administered lending and deposit rates moreover are more rigid when they are below their equilibrium level than when they are above our finding hence implies that the speed of monetary transmission is not uniform across all sectors of the economy and that a tightening monetary policy takes a longer time to impact the economy than an expansionary monetary policy

the newsvendor problem review and directions for future research in this paper we review the contributions to date for analyzing the newsvendor problem our focus is on examining the specific extensions for analyzing this problem in the context of modeling customer demand supplier costs and the buyer risk profile more specifically we analyze the impact of market price marketing effort and stocking quantity on customer demand how supplier prices can serve as a coordination mechanism in a supply chain setting integrating alternative supplier pricing policies within the newsvendor framework and how the buyer s risk profile moderates the newsvendor order quantity decision for each of these areas we summarize the current literature and develop extensions finally we also propose directions for future research

holiday price rigidity and cost of price adjustment the thanksgiving christmas holiday period is a major sales period for us retailers due to higher store traffic tasks such as restocking shelves handling customers questions and inquiries running cash registers cleaning and bagging become more urgent during holidays as a result the holiday period opportunity cost of price adjustment may increase dramatically for retail stores which should lead to greater price rigidity during holidays we test this prediction using weekly retail scanner price data from a major midwestern supermarket chain we find that indeed prices are more rigid during holiday periods than non holiday periods for example the econometric model we estimate suggests that the probability of a price change is lower during holiday periods even after accounting for cost changes moreover we find that the probability of a price change increases with the size of the cost change during both the holiday as well as non holiday periods we argue that these findings are best explained by higher price adjustment costs menu cost the retailers face during the holiday periods our data provides a natural experiment for studying variation in price rigidity because most aspects of market environment such as market structure industry concentration the nature of long term relationships contractual arrangements etc do not vary between holiday and nonholiday periods we therefore are able to rule out these commonly used alternative explanations for the price rigidity and conclude that the menu cost theory offers the best explanation for the holiday period price rigidity

price points and price rigidity abstract we study the link between price points and price rigidity using two data sets weekly scanner data and internet data we find that 9 is the most frequent ending for the penny dime dollar and ten dollar digits the most common price changes are those that keep the price endings at 9 9 ending prices are less likely to change than non 9 ending prices and the average size of price change is larger for 9 ending than non 9 ending prices we conclude that 9 ending contributes to price rigidity from penny to dollar digits and across a wide range of product categories retail formats and retailers

a risk averse newsvendor model under marketing dependency and price dependency abstract in this paper we analyze a single period inventory model where a risk averse newsvendor makes a joint decision on ordering pricing and marketing under the cvar risk measure criterion the newsvendor can exert marketing effort to enhance market demand we assume that the newsvendor s marketing effort affects the scale of the demand distribution and hence to model the marketing dependent demand as a multiplicative form we characterize sufficient conditions that guarantee existence and uniqueness of the optimal solutions under some mild assumptions on demand distribution expected demand function and marketing effort cost which are widely used in the related literature we show that the optimal order quantity increases in the newsvendor s marketing effort but the optimal price remains unchanged whether the demand is marketing dependent or not additionally we explore impact of exogenous parameters such as unit order cost salvage value and the newsvendor s risk aversion coefficient on the optimal decision variables and find that the optimal marketing effort always keeps the same changing direction with the optimal marketing independent order quantity as the exogenous parameters change this suggests that impact of the parameters on the optimal order quantity gets strengthened in the case of marketing dependent demand

a multi product risk averse newsvendor with exponential utility function abstract we consider a multi product newsvendor using an exponential utility function we first establish a few basic properties for the newsvendor regarding the convexity of the model and monotonicity of the impact of risk aversion on the solution when the product demands are independent and the ratio of the degree of risk aversion to the number of products is sufficiently small we obtain closed form approximations of the optimal order quantities the approximations are as easy to compute as the risk neutral solution we prove that when this ratio approaches zero the risk averse solution converges to the corresponding risk neutral solution when the product demands are positively negatively correlated we show that risk aversion leads to lower higher optimal order quantities than the solution with independent demands using a numerical study we examine convergence rates of the approximations and thoroughly study the interplay of demand correlation and risk aversion the numerical study confirms our analytical results and further shows that an increased risk aversion does not always lead to lower order quantities when demands are strongly negatively correlated

decision bias in the newsvendor problem with a known demand distribution experimental evidence in the newsvendor problem a decision maker orders inventory before a one period selling season with stochastic demand if too much is ordered stock is left over at the end of the period whereas if too little is ordered sales are lost the expected profit maximizing order quantity is well known but little is known about how managers actually make these decisions we describe two experiments that investigate newsvendor decisions across different profit conditions results from these studies demonstrate that choices systematically deviate from those that maximize expected profit subjects order too few of high profit products and too many of low profit products these results are not consistent with risk aversion risk seeking preferences prospect theory preferences waste aversion stockout aversion or the consequences of underestimating opportunity costs two explanations are consistent with the data one subjects behave as if their utility function incorporates a preference to reduce ex post inventory error the absolute difference between the chosen quantity and realized demand two subjects suffer from the anchoring and insufficient adjustment bias feedback and training did not mitigate inventory order errors we suggest techniques to improve decision making

a structural approach to identifying the sources of local currency price stability the inertia of the local currency prices of traded goods in the face of exchange rate changes is a well documented phenomenon in international economics this paper develops a structural model to identify the sources of this local currency price stability and applies it to micro data from the beer market the empirical procedure exploits manufacturers and retailers first order conditions in conjunction with detailed information on the frequency of price adjustments following exchange rate changes to quantify the relative importance of local non traded cost components markup adjustment by manufacturers and retailers and nominal price rigidities in the incomplete transmission of such changes to prices we find that on average approximately 60 of the incomplete exchange rate pass through is due to local non traded costs 8 to markup adjustment 30 to the existence of own brand price adjustment costs and 1 to the indirect strategic effect of such costs though these results vary considerably across individual brands according to their market shares

note on self restraint as an online entry deterrence strategy we develop a game theoretical model to show that in the markets where price consistency across channels is critical an incumbent brick and mortar retailer can deter the online entry of a pure play e tailer by strategically refraining from entering online in the markets where price consistency is not a constraint we find that the incumbent can deter the e tailer s entry only if it enters online and credibly operates the online channel as an independent profit center in other words the incumbent must be willing to cannibalize its own brick and mortar business by charging a low online price we also discuss some social welfare implications of retail online entry and the managerial insights of our analysis

demand uncertainty and returns policies manufacturers facing uncertain demand may induce distributors to carry ample stocks of their products by agreeing to accept returns of unsold goods for credit the authors model the manufacturer s decision to accept returns showing that this decision depends crucially on the nature of the demand uncertainty uncertainty over customer arrivals favors returns while uncertainty over consumers valuation of the manufacturer s product leads distributors to set retail prices too high from the manufacturer s standpoint when returns are allowed the authors show that returns can be expected to raise retail prices while maintaining shrinking distributor margins copyright 1995 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

the long term effect of renewable electricity on employment in the united kingdom abstract assessment of the employment impact of renewable electricity technologies is generally implemented through either complex and data intensive methods such as computable general equilibrium models or simplistic approaches normally focused on specific energy generation technologies such as employment factors in contrast this article proposes a transparent and easily reproducible econometric methodology based on the vector error correction model that uses aggregated and widely available data the model is applied to the power generation sector in the united kingdom using annual data from 1990 onwards and provides evidence that the long term employment impact of renewable technologies is much higher than the impact arising from deploying nuclear or natural gas technologies the impulse response function analysis indicates that a permanent 1 gigawatt hours increase in annual electricity supply generated by renewable technologies creates 3 5 jobs in the long term period finally this study derives the implications of the findings in the context of decarbonisation scenarios for the power sector in the united kingdom and assesses the extent to which decarbonisation pathways based on renewable electricity contribute to stimulating employment in the generation sector

structural breaks and electricity prices further evidence on the role of climate policy uncertainties in the australian electricity market the primary objectives and the strategies of a national electricity market are the efficient delivery of network services and the electricity infrastructure to meet the long term consumer s interests therefore the objective of this study is to explore whether electricity prices across the six australian states display instability such instability is closely associated with the presence of structural breaks in relevance to policy events on australian carbon policies the study makes use of weekly australian wholesale electricity prices spanning the period from june 8th 2008 to march 30th 2014 along with linear and non linear unit root testing methodologies the results provide supportive evidence that the australian electricity market can be described as a less stable electricity market which implies that a high degree of market power is exercised by generators across regional markets these findings are expected to have substantial consequences for the effectiveness of carbon dioxide mitigating policies especially when there is uncertainty as to whether the planned environmental policy is put in place for the lifespan of undertaken investments
