competitive coupon targeting with the advent of panel data on household purchase behavior and the development of statistical procedures to utilize this data firms can now target coupons to selected households with considerable accuracy and cost effectiveness in this article we develop an analytical framework to examine the effect of such targeting on firm profits prices and coupon face values we also derive comparative statics on firms optimal mix of offensive and defensive couponing the number of coupons distributed redemption rates face values and incremental sales per redemption among our findings when rival firms can target their coupon promotions at brand switchers the outcome will be a prisoner s dilemma in which the net effect of targeting is simply the cost of distribution plus the discount given to redeemers

product and price competition in a duopoly this paper examines the role of consumer preferences costs and price competition in determining the competitive product strategy of a firm in the model studied here there are two identical firms competing on product quality and price they face consumers who prefer a higher quality product to a lower quality product but differ in how much they are willing to pay for quality the consumers can also choose a substitute if they don t like the product price offerings of the two firms for the firms a higher quality product costs more to produce than a lower quality product the paper shows that the equilibrium strategy for each firm should be to differentiate its product from its competitor with the firm choosing the higher quality choosing the higher margin as well this differentiation however is not efficient that is it is possible to choose two other products and offer them at prices that cover their marginal cost and still satisfy consumers needs better in the aggregate a monopolist by contrast would differentiate his product line efficiently this suggests that cannibalization has different effects on product strategy than competition the paper also shows that if one firm enters the market first then it can defend itself from later entrants and gain a first mover advantage by preempting the most desirable product position

competitive targeted advertising with price discrimination this paper investigates the eects of price discrimination by means of targeted advertis ing in a duopolistic market where the distribution of consumers preferences is discrete and where advertising plays two major roles it is used by rms as a way to transmit relevant information to otherwise uninformed consumers and it is used as a price discrimination device we compare the rms optimal marketing mix advertising and pricing when they adopt mass advertising non discrimination strategies and targeted advertising price discrim ination strategies if rms are able to adopt targeted advertising strategies we nd that the symmetric price equilibrium is in mixed strategies while the advertising is chosen deter ministically our results also unveil that as long as we allow for imperfect substitutability between the goods rms do not necessarily target more ads to their own market in par ticular rms optimal marketing mix leads to higher advertising reach in the rival s market than in the rms own market provided that advertising costs are su ciently low in relation to the consumer s reservation value the comparison of the optimal marketing mix under mass advertising strategies and targeted advertising strategies reveals that targeted adver tising might constitute a tool to dampen price competition in particular if advertising costs are su ciently low in relation to the value of the goods we obtain that average prices with non discrimination mass advertising are below those with price discrimination and targeted advertising regardless of the market segment accordingly when i goods are imperfect substitutes ii advertising is not too expensive and iii targeted advertising constitutes an eective price discrimination tool price discrimination through targeted advertising may be detrimental to social welfare since it boosts industry pro ts at the expense of consumer surplus

how to improve the performance of carbon tax in china abstract the chinese government committed to controlling carbon dioxide co 2 emissions and promoting development of non fossil fuels thus it becomes a top priority for the government to develop effective climate policies against such background this paper develops a new multi country computable general equilibrium cge model with detailed energy disaggregation this study evaluates the impact of single policy instrument carbon tax and combined policy mixes in order to investigate driving factors affecting the policy performance the main findings are as follows firstly the driving factors can be classified into two types the first type of factors affects cost effectiveness significantly while the second type generates considerable effect on emission performance secondly cross border externalities function as important barriers to the co 2 emission reduction since they imply extra competitiveness loss and result in considerable carbon leakage finally this paper considers two integrated policy mixes wherein carbon tax revenue is recycled to reduce capital tax or support clean energy subsidy these policy mixes can improve both cost effectiveness and emission performance and thus perform better than carbon tax alone in this way carbon tax revenue can be used to improve the performance looking ahead complicated policy mixes are preferred to improve the performance of china s carbon tax

the role of brand image and product characteristics on firms entry and oem decisions we investigate the optimal market entry and original equipment manufacturer oem decisions of a firm facing a market in which firms brands can be horizontally differentiated and products can be vertically differentiated the entrant might sell under its own brand and compete with an incumbent become a supplier to the incumbent or both findings reveal that when consumers perceive the firms are horizontally and vertically differentiated the entrant profits by simultaneously entering the market and establishing an oem arrangement with the incumbent in such competitive scenarios both buyer and seller increase profits by agreeing on wholesale prices that are not too low which softens both horizontal and vertical conflict between the firms findings also show that the incumbent may prefer to pay high wholesale prices to the entrant even if the incumbent had the option to source the product independently at a lower marginal cost when firms have the capability of producing each other s product lines su

do first time house buyers receive financial transfers from their parents using danish longitudinal data with information about wealth for a sample of first time house buyers and their parents we test whether there are direct financial transfers from parents to children in connection with the house purchase or in connection with unemployment spells occurring just after the purchase when children typically hold few liquid assets first we document that child and parent financial resources are correlated then we introduce conditioning variables and exploit the panel aspect of the data to also condition on fixed unobserved factors which arguably govern preferences and or productivity we find no evidence of direct financial transfers

the cross country implications of alternative climate policies abstract because of worldwide growing concerns about global climate change great interest has been expressed in the potential of alternative climate policies to reduce global carbon emissions in this paper we compare cross country implications of alternative climate policies including unilateral and multilateral climate policies our main findings are as follows firstly there are large differences in cross country effects of alternative unilateral climate policies when the same given carbon emission reductions are achieved in each abating country respectively meanwhile cross border externalities undermine efficiency of unilateral climate policies secondly there are significant differences in cross country implications of alternative multilateral climate policies when the same global emission reductions are allocated in several different ways among abating countries thirdly it is difficult to reach a stable global climate treaty since any abating country has the incentive to argue for small carbon emission reductions finally multilateral climate policies can reduce the negative impacts of cross border externalities but cannot cure all cross border externalities looking ahead it will be a great policy challenge for the world to reduce carbon emissions in a cost effective way

intergenerational transfers and liquidity constraints a growing body of evidence indicates that liquidity constraints could affect a substantial proportion of u s consumers but little is known about why these constraints might exist an important but little explored issue is the relationship between inter vivos intergenerational transfers and liquidity constraints these transfers can ease borrowing constraints empirical transfer patterns match those predicted from a model in which transfers are allocated to liquidity constrained consumers in particular the distinction between current and permanent incomes of potential recipients is a key aspect of private transfer behavior the findings have important implications for our understanding of consumer behavior

sector choice multiple job holding and wage differentials evidence from poland this article uses data from poland to investigate the role played by wage differentials between the public and private sectors in influencing sector choice and the decision to moonlight standardising for worker characteristics and allowing for sector selection effects we find i a substantial private sector wage premium ii wage differentials are a significant determinant of sector choice and iii the desire to moonlight is particularly strong among those who face the greatest wage gap that is university educated employees

the effect of taxation on labour supply the case of moonlighting the authors provide a simple test of supply side economics by estimating the responsiveness of moonlighting labour supply to changes in the marginal tax rate and the wage rate while standard theory teachers that changes in taxes and wage should have opposite and equal effects on labour supply taxes affect the entire asset position of the household in the short run an adjustment of hours in the second job may be the only option available to an individual in responding to a tax change thus analyses based on after tax wages may understate supply side effects to estimate these effects a tobit procedure is employed the empirical results suggest a backward bending supply curve over thet range of moonlighting hours data consist of a subsample of male blue collar workers from the 1978 cross section of the panel study of income dynamics

price discrimination in free entry markets using a spatial model of monopolistic competition we investigate price discrimination in free entry zero profit markets we show that when brands are heterogeneous competition does not prevent discrimination the power to earn economic profits is not necessary for a firm to maintain discriminatory prices our model treats formally the fact that consumers difer not only in the utility they derive from a good but also in how strongly they prefer one brand over all others in markets where firms are very competitive sorting consumers on the strength on brand preference produces larger price differentials between groups than sorting on the basis of consumers reservation prices for the good when firms sort customers on the basis of strength of brand preference however we find that the output and welfare effects are generally less favorable than when sorting is more closely related to consumers reservation prices

input substitution effect in china s chemical industry evidences and policy implications abstract the chemical industry is one of the six high energy consuming and emission intensive sectors in china and the chinese government has focused its attention on energy saving and emissions reduction in the sector with the aim of contributing to the objective of energy saving and emission reduction in the sector this article studies the external substitution relationship of capital energy and labor energy using the translog production function and ridge regression the results are as follow the output elasticities of energy labor and capital are positive the substitution elasticities of capital labor capital energy and labor energy are positive and stable and their values are close to 1 which indicates that the three factors are substitutes for one another furthermore based on the above function we measure the level of energy saving and emissions reduction under different scenarios in 2012 policy implications of the results are provided

marketing information a competitive analysis selling information that is later used in decision making constitutes an increasingly important business in modern economies jensen jensen fred o 1991 information services congram friedman eds the ama handbook of marketing for the service industries chapter 22 ama com new york 423 443 information is sold under a large variety of forms industry reports consulting services database access and or professional opinions given by medical engineering accounting financial and legal professionals among others this paper is the first attempt in marketing to study competition in the rapidly emerging information sector specifically we are interested in answering the following questions 1 is competition fundamentally different when competing firms sell information rather than traditional goods and services and if yes why 2 what are the implications of such differences for decision makers marketers and regulators 3 can we explain some of the observed marketing strategies in the information industry as such the audience of the paper includes academics as well as professionals who are interested in understanding what is specific about competition in information markets familiarity with the practical implications of such differences and understanding of the mechanisms that drive them is essential for those who are faced with the problem of marketing information to answer the above research questions we build a simple game theoretic model that consists of two firms selling information to a population of consumers who are heterogeneous in their willingness to pay for the quality of information the most important features of the model are the following information products sold by the two firms are modeled as random draws from two normal distributions having equal mean the variances of these distributions and their correlatedness constitute the product attribute space which is assumed to be common knowledge consumers are interested in assessing the mean of the distributions and to do so they can buy the sample from any of the firms or they can buy both samples and combine them to obtain a more accurate estimate quality of information is linked to the accuracy of consumers estimate of the mean which in turn is influenced by the accuracy of each sample as well as by their correlatedness consumers utility depends on the quality of information they purchased on their inherent utility for quality taste and on the total price they paid to acquire information knowing consumer preferences firms simultaneously price their information products the main finding of the paper is that information markets face unique competitive structures in particular the qualitative nature of competition changes depending on basic product characteristics while traditional products and services compete either as substitutes or as complements in the relevant product attribute space information may be one or the other depending on its position within the same product attribute space said differently the nature of competition changes qualitatively with a continuous change in basic product attribute levels the intuition behind this finding is the following when purchasing information consumers facing important decisions may find it beneficial to purchase from several information sellers this is more likely to happen when the reliability of information is low and the sources of information are independent under such conditions information products tend to be complements and as a result competition between sellers is relatively mild in the opposite case when information is reliable and or sellers sources are highly correlated consumers are satisfied after consulting a single source in this case information products are substitutes and sellers tend to undercut one another s prices to induce consumers to choose their brand understanding this discontinuity in competitive structures has important implications for decision makers as very different strategies are optimal under different product characteristics under substitution traditional strategies to avoid competition e g differentiation are recommended when the competing products reliability is generally low they are complements firms are better off accommodating competition in fact we find that a firm may benefit from inviting a competitor finally our findings are also important for regulators of information markets as the literature on complementarity suggests price fixing agreements between firms offering complementary products may benefit firms as well as consumers

cost based modelling of optimal emission quota allocation abstract given that a fixed national emission reduction target could be achieved by imposing emission quotas among multiple decision making units under administration a novel nonlinear programming approach is proposed in this paper to obtain an optimal emission quota allocation in a least cost way marginal emission abatement cost curves are simulated based on the environmental performance and marginal emission abatement costs measured in a set of parametric directional output distance functions with multi inputs and multi outputs further the proposed model is applied to empirically investigate the optimal carbon emission quota allocation for china s building construction industry among thirty three provinces in three different regions the results indicate that the relatively developed eastern region in china has higher marginal emission abatement cost and can be imposed with more emission quotas while the central and western regions can undertake more emission reduction approximately 74 million rmb can be saved by implementing the optimal emission allocation proposed in this paper as compared to a uniform emission quota allocation the findings are of great theoretical methodological and practical significance for policymakers and social science researchers in terms of climate change mitigation

how to price discriminate when tariff size matters firms that serve a large market with many diverse consumer types use discriminatory or nonlinear pricing to extract higher revenue inducing consumers to separate by self selecting from a large number of tariff options but the extent of price discrimination must often be tempered by the high costs of devising and managing discriminatory tariffs including costs of supporting consumers in understanding and making selection from a complex menu of choices these tariff design trade offs occur in many industries where firms face many consumer types and each consumer picks the number of units to consume over time examples include wireless communication services other telecom and information technology products legal plans fitness clubs automobile clubs parking healthcare plans and many services and utilities this paper evaluates alternative ways to price discriminate while accounting for both revenues and tariff management costs the revenue maximizing menu of quantity price bundles can be very or infinitely large and hence not practical instead two part tariffs 2pts which charge a fixed entry fee and a per unit fee can extract a large fraction of the optimal revenue with a small menu of choices and they become more attractive once the costs of tariff management are factored in we show that three part tariffs 3pts which use an additional instrument the free allowance are an even more efficient way to price discriminate a relatively small menu of 3pts can be more profitable than a menu of 2pts of any size this 3pt menu can be designed with less information about consumer preferences relative to the menu of two part tariffs which in order to segment customers optimally needs fine grained information about preferences our analysis reveals a counterintuitive insight that more complex tariffs need not always be more profitable it matters whether the complexity is from many choices or more pricing instruments

research note consumer addressability and customized pricing the increasing availability of customer information is giving many firms the ability to reach and customize price and other marketing efforts to the tastes of the individual consumer this ability is labeled as consumer addressability consumer addressability through sophisticated databases is particularly important for direct marketing firms catalog retailers such as l l bean and land s end credit card issuing banks and firms in the long distance telephone market we examine the strategic implications of consumer addressability on competition between database direct marketing firms we address questions such as in a competitive environment how should firms invest in addressability will future improvements in the degree of addressability increase or mitigate the intensity of competition between the firms will greater addressability always be beneficial for firms we model competition between two firms in a market where consumers differ on a horizontal attribute of product differentiation the market comprises consumers located on a linear attribute space and firms located at the ends of the line we represent the degree of addressability or the reach of a firm s database as the proportion of consumers at each point in the market who are in the firm s database consequently the firm can offer these consumers customized prices consumer addressability creates two effects that govern the competition between firms a surplus extraction effect because a firm might address a consumer who is not reached by its competitor and a competitive effect that is created by the set of consumers who can be addressed by both firms the key results of the paper pertain to when the addressability decision is endogenous when the extent of market differentiation or consumer heterogeneity in preferences for a product brand attribute as well as the incremental cost of addressability are sufficiently large firms make symmetric investments in equilibrium given high costs firms choose sufficiently low levels of addressability low addressability and high levels of market differentiation both help reduce price competition which facilitates symmetric choice of addressability by the firms in equilibrium however when market differentiation and the cost of incremental addressability become small firms face the prospect of destructive competition as a result they strategically differentiate in their choice of addressability to mitigate this competition interestingly even in the extreme case when incremental addressability is costless not every firm chooses full addressability in equilibrium this has useful implications for direct marketing given that the advances in information technology should improve the ability of firms to address their consumers it might indeed not be desirable for all direct marketing firms to indefinitely pursue greater addressability as costs of doing so decline the analysis also shows an interesting effect of market differentiation in addressable markets equilibrium profits can decrease with an increase in market differentiation when the marginal cost of addressability is sufficiently high finally we discuss the competitive outcome that would result when firms compete with addressable as well as uniform posted prices

on the optimal product line selection problem with price discrimination product line design decisions are determinant for a firm s market success and simultaneously very costly to implement and change to evaluate the profitability of a design a number of mathematical programming approaches have been proposed in the last three decades typically nonlinear integer optimization problems that can only be tackled heuristically for real world instances recently chen and hausman 2000 efficiently exploited the fractional programming properties of a stylized model for product line and price selection with the objective to maximize contribution given homogeneous customer behavior by an aggregate multinomial logit choice model we extend the approach of chen and hausman chen k d w h hausman 2000 technical note mathematical properties of the optimal product line selection problem using choice based conjoint analysis management sci 46 2 327 332 to determine an optimal product line under a personalized or group pricing strategy in markets with multiple heterogeneous consumers such that total profit including fixed costs is maximized personalized group pricing is a growing discrimination strategy that more and more businesses are realizing is not only very profitable but also often implementable in the era of e business our problem formulation allows to incorporate commonly applied attraction choice models including the multinomial logit the bradley terry luce and approximately the first choice model though the problem is generally nonlinear we show that the fractional substructure resulting from attraction choice models can still be exploited to globally solve real world instances in reasonable time

quality and price personalization under customer recognition a dynamic monopoly model with contrasting equilibria abstract we present a model of market hyper segmentation where a monopolist acquires within a short time all information about the preferences of consumers who purchase its vertically differentiated products the firm offers a new price quality schedule after each commitment period lower consumer types may have an incentive to delay their purchases until next period to obtain a better introductory offer the monopolist counters this incentive by offering higher informational rents considering the dynamic game played by the monopolist and its customers we find that there is always a markov perfect equilibrium mpe in which the firm immediately sells the good to all customers offering the mussa rosen static equilibrium schedule to first time customers and getting full commitment profits however if the commitment period between two offers is long enough there is another mpe with gradual market expansion contrary to the coasian result for a durable good monopoly we find that in both equilibria the profit of the monopolist increases and the aggregate consumers surplus decreases as the interval of commitment shrinks the model yields policy implications for regulations on collection and storage of customers information

bundling strategies when products are vertically differentiated and capacities are limited we consider a seller who owns two capacity constrained resources and markets two products components corresponding to these resources as well as a bundle comprising the two components in an environment where all customers agree that one of the two components is of higher quality than the other and that the bundle is of the highest quality we derive the seller s optimal bundling strategy we demonstrate that the optimal solution depends on the absolute and relative availabilities of the two resources as well as upon the extent of subadditivity of the quality of the products the possible strategies that can arise as equilibrium behavior include a pure components strategy a partial or full spectrum mixed bundling strategy and a pure bundling strategy where the latter strategy is optimal when capacities are unconstrained these conclusions are contrary to findings in the prior literature on bundling that demonstrated the unambiguous dominance of the full spectrum mixed bundling strategy thus our work expands the frontier of bundling to an environment with vertically differentiated components and limited resources we also explore how the bundling strategies change as we introduce an element of horizontal differentiation wherein different types of customers value the available components differently

behavior based pricing production efficiency and quality differentiation in a two period vertical duopoly we examine how behavior based price discrimination bpd affects the firms endogenous quality differentiation and profits the firms relative production efficiency defined as the ratio between their unit cost difference and quality difference plays a crucial role with exogenous product qualities bpd always decreases the profits of the more efficient firm but increases those of the sufficiently less efficient firm anticipating its period 2 disadvantage in price discrimination the less efficient firm competes more vigorously and also gains more in period 1 than its competitor for the sufficiently less efficient firm its period 1 gain dominates its period 2 loss and its total profits increase with endogenous quality choices bpd does not alter the low end quality at the lower bound of the quality space but increases the high end quality enlarging quality differentiation this is because under bpd each firm s profit gain decreases or its profit loss increas

research note competitive bundling and counterbundling with generalist and specialist firms bundling which is the practice of selling two or more products or services in a package is a pervasive marketing practice and is often used as a strategic competitive tool however there has not been enough consideration of competitive bundling situations in which exit of a competitor is not a concern in this paper we address this issue by identifying conditions under which strategic competitors may or may not resort to bundling when competitor exit considerations are absent we study competition between a multiproduct generalist firm and two single product specialist firms in two product categories one of which has undifferentiated products and the other has differentiated products in our model the specialist firms can form an alliance to bundle their products in competing with the generalist firm in contrast to the previous literature we find that concurrent bundling by competitors if it occurs in equilibrium is profitable we also find that when one competitor bundles and the other does not the bundling firm gains a greater share of customers and makes a higher profit however when conditions favor counterbundling by a competitor such counterbundling helps the competitor retain its customers finally we note that under other market conditions concurrent bundling by competitors escalates price competition to the extent that retaining customers through bundling is not profitable in such a case we show that strategic competitors are better off having asymmetric product lines with one competitor bundling and the other selling unbundled

government debt redistributive fiscal policies and the interaction between borrowing constraints and intergenerational altrusim abstract we show how borrowing constraints intergenerational altruism and their interaction shape the aggregate savings response to government debt and fiscal policies that redistribute resources between living generations we also characterize the conditions under which borrowing constraints bind and the altruistic transfer motive operates in terms of the strength of the altruism motive the shape of the lifetime productivity profile the willingness to substitute consumption intertemporally and other factors finally we characterize the dynamic response of aggregate savings to nonneutral government debt policies in economies with binding borrowing constraints

the 2003 isms practice prize winner optimizing rhenania s direct marketing business through dynamic multilevel modeling dmlm in a multicatalog brand environment we introduce dynamic multilevel modeling dmlm to a multicatalog brand environment to determine the optimal frequency size and customer segmentation of direct marketing activities this optimization method leverages multicatalog brand effects including the utilization of prior customer ordering behavior maximization of customer value and customer share and economies of scale and scope in printing and mailing this enhancement of the original dmlm approach is called dynamic multidimensional marketing dmdm with dmlm alone rhenania a german direct mail order company turned its catalog mailing practices around and consequently rose from the number 5 to the number 2 market position the dmlm approach was so effective that two major competitors could be bought out improvements provided by dmdm were threefold more efficient resource allocation across all catalog brands more accurate customer microsegmentation and more effective reactivation presently the company s target is to transform single brand customer relationships into two or three brand relationships with higher revenue per customer as a consequence the rhenania group s performance was decoupled from the overall market trend

job amenity and the incidence of double work abstract the hypothesis that workers in jobs associated with an amenity are more prone to moonlighting is derived and tested if earnings fall for such jobs it is rational to have two jobs while for jobs with no amenity a fall in earnings causes a rational worker to leave the sector altogether an amenity can be expected for instance for workers in primary sectors and evidence that farmers at an increasing rate have double occupations are provided the comparative statics on the models shows among other things that wage increases outside the amenity sector may have different effects than wage decreases inside the sector the models are tested on data on farmers and to some extent the regressions support the theoretical models

targeted advertising strategies on television the personal video recorder pvr facilitates the use of targeted advertising by allowing companies to monitor television viewing behavior and to build demographic profiles of viewers from the data that are collected our research explores the extent to which an advertiser should allocate resources to increase the quality of its targeting we present a game theoretic model that extends the conventional measurement of targeting quality by exploring the trade off between two measures accuracy and recognition accuracy measures the likelihood that any target segment prediction is correct while recognition conversely measures the likelihood that any member of the target segment is identified we find that the relative resources allocated to improving accuracy and recognition depend upon the size of the population of viewers the propensity of viewers to skip commercials the overall cost of airing commercials and the competitive environment furthermore the incentives to improve accuracy are markedly different from those to improve recognition although improving accuracy does not affect the extent of price competition improving recognition leads to intensified price competition and reduced profitability in the product market thus when facing a competitor that pursues a strategy to improve its recognition of potential customers an advertiser should choose to reduce its investment in recognition and increase its investment in accuracy

behavior based discrimination is it a winning play and if so when with advances in technology the collection of information from consumers at the time of purchase is common in many categories this information allows a firm to straightforwardly classify consumers as either new or past consumers this opens the door for firms to implement marketing that a discriminates between new and past consumers and b entails making offers to them that are significantly different our objective is to examine the competitive effects of marketing that tailors offers to consumers based on their past buying behavior in a two period model with two competing firms we assume that each firm is able to commit about whether or not to implement behavior based discrimination bbd i e to add benefits to its offer for past consumers in the second period when the firms are identical in their ability to add value to the second period offer bbd generally leads to lower profits for both firms past customers are so valuable in the second period that bbd leads to cutthroat competition in the first period as a result the payoffs associated with the implementation of bbd form a prisoner s dilemma interestingly when a firm has a significant advantage over its competitor one firm has the capability to add more benefits for its past customers than the other it can increase its profit versus the base case even when there is significant competition in the second period moreover the firm at a disadvantage sometimes finds that the best response to bbd by a strong competitor is to respond with a uniform price and avoid the practice completely

motives for private transfers over the life cycle an analytical framework and evidence for peru abstract this paper tests for the motives for private income transfers we consider two motives altruism and exchange the question of private transfer motives is important because such motivation can influence the effects of public income transfers on the distribution of income using a household survey for peru we find that transfer amounts received increase with recipient pre transfer income which contradicts a key prediction of the strong form of the altruism hypothesis but is consistent with exchange we also find that capital market imperfections are likely to be an important cause of private transfers and that social security benefits crowd out the incidence of private transfers

bundling and competition for slots we consider competition between sellers selling multiple distinct products to a buyer having k slots under independent pricing a pure strategy equilibrium often does not exist and equilibrium in mixed strategy is never efficient when bundling is allowed each seller has an incentive to bundle his products and an efficient technology renting equilibrium always exists furthermore in the case of digital goods or when sales below marginal cost are banned all equilibria are efficient comparing the mixed strategy equilibrium with the technology renting equilibrium reveals that bundling often increases the buyer s surplus finally we derive clear cut policy

customer poaching and advertising this paper is a first look at the dynamic effects of customer poaching in homogeneous product markets where firms need to invest in advertising to generate awareness when a firm is able to recognize customers with different purchasing histories it may send them targeted advertisements with different prices it is shown that only the firm which advertises the highest price in the first period will engage in price discrimination a practice that clearly benefits the discriminating firm this poaching gives rise to the race for discrimination effect through which price discrimination may act actually to soften price competition rather than intensify it as a result all firms may become better off even when only one of them can engage in price discrimination this paper offers a first attempt to evaluate the effects of price discrimination on the efficiency properties of advertising in markets with low or no advertising costs allowing firms to price discriminate leads them to provide too little advertising which is not good for consumers and overall welfare only in markets with high advertising costs might firms overadvertise regarding the welfare effects price discrimination is generally bad for welfare and consumer surplus though good for firms

competitive promotional strategies this article analyzes the equilibrium pricing strategies of brands engaged in a pricing game each brand has a monopoly market loyal consumers and competes with others in a common market called brand switchers in the case of a duopoly it is shown that the behavior of the brand switchers characterizes the equilibrium behavior of the duopolists this article focuses on two key comparative statics namely the depth of discounts away from a regular high price and the probability of giving a deal or the frequency of deals how these properties vary with the size of the loyal markets and the behavior of the brand switching population is discussed copyright 1988 by the university of chicago

liquidity constraints as a cause of moonlighting an investigation of whether some workers respond to liquidity constraints by moonlighting is carried out using a unique large data set it is found that workers are more likely to moonlight if 1 they have low current incomes relative to their educational attainment and 2 they plan to purchase a house or a car during the next six months

multiple job holding in the united kingdom evidence from the british household panel survey this article examines the determinants of multiple job holding in the uk we address these issues using data from the first 11 waves of the british household panel survey bhps which covered the period from 1991 to 2001 evidence from the bhps does not support the hypotheses of main job hours constrained and main job insecurity we argue that the incentive for moonlighting in the uk is due to financial pressures and the desire for heterogeneous jobs the empirical work is carried out separately for men and women

family composition and off farm participation decisions in israeli farm households this article studies the relationship between the off farm participation behavior of farm operators and their spouses and the demographic composition of the household we focus on farm families without parents siblings or partners and examine the effects of the existence of elderly children of the farm couple we find that both the father and the mother tend to reduce their participation in off farm work as the number of elderly children rises this result holds even after controlling for observed characteristics we also find that the effect of elderly children stems from considerations related to both farm production and household production

individual marketing with imperfect targetability our research investigates the competitive ramifications of individual marketing and information management in today s information intensive marketing environments the specific managerial issues we address are as follows first what kinds of incentive environments do competing firms face when they can only target individual customers imperfectly second does the improvement in an industry s targetability intensify price competition in the industry such that all competing firms become worse off third should a firm share its customer knowledge so as to improve its rival s targetability fourth how should an information vendor sell its information that can improve a firm s targetability finally do competing firms have the same incentives to invest in their own targetability to answer those questions we develop a simple model a la narasimhan 1988 in which each of the two competing firms have their own loyal customers and compete for common switchers we assume that each firm can classify its own loyal customers and switchers correctly only with a less than perfect probability this means that each firm s perceived customer segmentation differs from the actual customer segmentation based on their perceived reality these two competing firms engage in price competition as an extension we also allow the competing firms to make their investment decisions to acquire targetability we show that when individual marketing is feasible but imperfect improvements in targetability by either or both competing firms can lead to win win competition for both even if both players behave noncooperatively and the market does not expand win win competition results from the fact that as a firm becomes better at distinguishing its price insensitive loyal customers from the switchers it is motivated to charge a higher price to the former however due to imperfect targetability each firm mistakenly perceives some price sensitive switchers as price insensitive loyal customers and charges them all a higher price these misperceptions thus allow its competitors to acquire those mistargeted customers without lowering their prices and hence reduce the rival firm s incentive to cut prices this effect softens price competition in the market and qualitatively changes the incentive environment for competing firms engaged in individual marketing a prisoner s dilemma occurs only when targetability in a market reaches a sufficiently high level this win win perspective on individual marketing has many managerial implications first we show that superior knowledge of individual customers can be a competitive advantage however this does not mean that a firm should always protect its customer information from its competitors to the contrary we find that competing firms can all benefit from exchanging individual customer information with each other at the nascent stage of individual marketing when firms targetability is low indeed under certain circumstances a firm may even find it profitable to give away this information unilaterally however as individual marketing matures as firms targetability becomes sufficiently high further improvements in targetability will intensify price competition and lead to prisoner s dilemma therefore it is not only prudent politics but also a business imperative for an industry to seize the initiative on the issue of protecting customer privacy so as to ensure win win competition in the industry second we show that the firm with a larger number of loyal customers tends to invest more in targetability when the cost of acquiring targetability is high however the firm with a smaller loyal base can through information investment acquire a higher level of targetability than the firm with a larger loyal base as long as the cost of acquiring targetability is not too high as the cost further decreases competing firms will all have more incentives to increase their investments in targetability until they achieve the highest feasible level third an information vendor should make its information available nonexclusively exclusively when its information is associated with a low high level of targetability when the vendor does sell its information exclusively it should target a firm with a small loyal following if it can impart a high level of targetability to that firm finally our analysis shows that an information intensive environment does not doom small firms in fact individual marketing may provide a good opportunity for a small firm to leapfrog a large firm the key to leapfrogging is a high level of targetability or customer knowledge

domestic climate policies and the wto the kyoto protocol gives annex 1 countries considerable flexibility in the choice of domestic policies to meet their emissions commitments possible climate policies include carbon energy taxes subsidies energy efficiency standards eco labels and government procurement policies in order to meet their targets with minimum adverse effects on their economies annex 1 governments with differentiated legal and political systems are highly likely to pursue these policies that may have the potential to bring them into conflict with their wto obligations this paper explores the potential interaction between these domestic climate policies and wto rules it argues that their potential conflicts can be avoided or at least minimised if wto rules are carefully scrutinised and efforts are made early on to ensure that the proposed climate policies comply with them it suggests an early process of pursuing consultations between wto members and the parties tclimate change convention and points to the need of further exploring ways to enhance synergies between the trade and climate regimes

the puzzling pattern of multiple job holding across u s labor markets multiple job holding mjh rates differ substantially across u s regions states and metropolitan areas rates decrease markedly with respect to labor market size these patterns have been largely overlooked despite being relatively fixed over at least the past 20 years this article explores explanations for these persistent differences we account for roughly two thirds of the mean absolute deviation in mjh across local labor markets msas the results suggest that variation in mjh across labor markets is driven by labor market differences in job opportunities and worker preferences most important in explaining variation in mjh are msa industry and occupation structure ancestry shares commute times and to a lesser extent labor market churn

will carbon motivated border tax adjustments function as a threat abstract due to large incremental carbon emissions china might become an important target country of cbta carbon motivated border tax adjustments to levy cbta could reduce china s emissions meanwhile china s emissions reduction could also be achieved by china s climate policies termed as cbta emissions equivalent policies this paper contributes to the discussion on cbta by comparing the potential regional effects of cbta and cbta emissions equivalent policies the main findings are as follows 1 cbta and cbta emissions equivalent policies would result in relocations of outputs across regions and countries affect the structure of economy and contribute to world s emissions reduction 2 there would be significant differences in the regional effects between cbta and cbta emissions equivalent policies 3 compared to carbon tax cbta would be a costly and inefficient policy instrument to reduce emissions but could function as an effective coercion strategy 4 these policies would result in competitiveness issue and rebound effects wherein different countries would be affected differently china is a large economy and energy consumer with high openness to international trade looking ahead the chinese government should consider the potential interactions between china and other economies when designing tax reforms

multiple job holding the artist s labour supply approach this article analyses a labour supply model in which individuals maximize a utility function that depends on leisure time consumption and time devoted to an activity that is termed artistic this activity may generate income that depends nonlinearly on hours dedicated to it the individual can also work in the labour market an activity that does not increase utility by itself in exchange for an hourly wage and obtain income not related to hours conditions are obtained that sort individuals into two groups part time and full time artists deriving their labour supply functions in both activities the predictions of the model are tested empirically using a sample of musicians from a uruguayan performing rights society increases in outside wages drive part time artists out of the labour market but no significant increase in arts hours is detected higher nonlabour income also reduces nonarts work time of part time artists but does not have a significant impact in their arts hours conversely arts

border adjustment for european emissions trading competitiveness and carbon leakage unilateral or sub global policies to combat climate change are potentially sensitive to free riding and carbon leakage one way of dealing with carbon leakage and competitiveness is the imposition of border adjustment measures for competing imports for example in the form of the obligation to importers of goods to purchase and surrender emissions allowances to the authorities when importing in this paper we explore some implications of border adjustment measures in the eu ets for sectors that might be subject to carbon leakage we examine the implications of two variants of these measures on the competitiveness of these sectors and on the global environment with the help of a multi sector multi region computable general equilibrium cge model of the global economy our calculations suggest that border adjustment might reduce the sectoral rate of leakage of the iron and steel industry rather forcefully but that the reduction would be less for the mineral products sector including cement the reduction of the overall or macro rate of leakage would be modest so from an environmental point of view border tax adjustments would not be a very effective policy measure but might mainly be justified by considerations of sectoral competitiveness

comparing policies to combat emissions leakage border carbon adjustments versus rebates we explore conditions determining which anti leakage policies might be more effective complements to domestic greenhouse gas emissions regulation we consider four policies that could be combined with unilateral emissions pricing to counter effects on international competitiveness a border charge on imports a border rebate for exports full border adjustment and domestic output based rebating each option faces different potential legal hurdles in international trade law each also has different economic impacts while all can support competitiveness none is necessarily effective at reducing global emissions nor is it possible to rank order the options effectiveness depends on the relative emissions rates elasticities of substitution and consumption volumes we illustrate these results with simulations for the energy intensive sectors of three different economies the united states canada and europe although most controversial full border adjustment is usually most effective but output based rebating for key manufacturing sectors can achieve many of the gains

consumer privacy and marketing avoidance a static model we introduce the concept of marketing avoidance consumer efforts to conceal themselves and to deflect marketing the setting is one in which sellers market some item through solicitations to potential consumers who differ in their benefit from the item and suffer harm from receiving solicitations concealment by one consumer induces sellers to shift solicitations to other consumers whereas deflection does not solicitations cause two externalities direct harm on consumers and the indirect cost of consumer concealment and deflection we find that in markets where the marginal cost of solicitation is sufficiently low efforts by low benefit consumers to conceal themselves will increase the cost effectiveness of solicitations and lead sellers to market more however concealment by high benefit consumers leads sellers to market less furthermore concealment by low benefit consumers increases direct privacy harm and consumer welfare is higher with deflection than concealment finally it is optimal to impose a charge on solicitations

research note using basket composition data for intelligent supermarket pricing how can supermarkets use the vast data they have to design strategies to compete for large basket shoppers potentially their most profitable customers we say analyze the data to glean basket composition of heterogeneous consumers of theoretical and practical interest is the question will our suggestion improve supermarket profits and if so by what pricing strategies by answering this we can also answer the question do results of extant research on single product marketing that using such information intensifies competition and lowers profits generalize to multiproduct marketing by supermarkets that carry several products and whose patrons purchase multiple items we derive equilibrium data based intelligent pricing strategies that also produce increased supermarket profits what is more interesting is our result that data analysis is profitable whether or not a competitor undertakes data analysis if not too costly implementing data analysis is a dominant strategy moreover with comprehensive data analysis connecting basket information and household data stores can increase profits further by targeting rewards at individual households thereby segmenting the market more completely in contrast to past research findings we show that for supermarkets even under competition use of information on past purchases enables intelligent pricing better segmentation and higher profits

moonlighting multiple motives and gender differences this paper examines the incidence and reasons for moonlighting with a focus on gender differences the study specifies and estimates a bivariate probit model of labour supply and the decision to hold more than one job it is found that the factors leading men and women to moonlight are similar a wage decomposition analysis reveals that 93 percent of the differential between male and female moonlighters wages is not explained by differences in characteristics and little connection is found between an individual s human capital and their moonlighting wage finally it is found that moonlighters are less likely to report their income

utility based estimation of labour supply functions in the regular and irregular sectors recent theoretical work on labor supply has shown that the tax and transfer system can induce some individuals to work in the irregular labor market models designed to represent such behavior are unable to sign unambiguously the impact of the marginal tax rate as well as many key exogenous parameters on the hours supplied in the irregular market except under strong restrictions on preferences in this paper the authors estimate a simultaneous labor supply model that allows testing some of the more common assumptions found in the literature using a unique data set on the underground economy of the metropolitan area of quebec city canada estimates of elasticities with respect to predetermined variables are presented moreover they test and empirically reject the assumptions of perfect substitution between regular and irregular work activities as well as additive separability of the utility function copyright 1992 by royal economic society

a time series analysis of labour absence in australia the authors find evidence from australian time series data supporting two hypotheses about the determination of labor absence first labor absence modeled in a utility maximizing framework that stresses the opportunity cost of labor absence receives considerable support from the data variables that change the slope and or shift the budget constraint facing workers affect labor absence secondly the authors find tentative evidence that coercive or difficult work environments which apparently affect job satisfaction adversely affect labor absence in particular it appears that labor absence is a leading indicator of a deteriorating industrial relations environment characterized by increased industrial disputation copyright 1989 by mit press

analysis of private transfers with panel fixed effect censored model estimator abstract understanding private transfer is important for safety net policies because private transfer provides economic benefits similar to those of public programs such as unemployment insurance and pension applying honore s econometrica 60 1992 533 panel fixed effect censored model estimator to korean data we show that private transfer is altruistically motivated and there is a strong crowding out effect of public transfer on private transfer we also find that low income people suffered to different degrees during the financial crisis period of 1997 to 1998 this finding and the crowding out effect may be taken as failures of the korean public transfer programs during the period

why are there large differences in performances when the same carbon emission reductions are achieved in different countries great interest has been in unilateral climate policies given present difficulty of establishing stable global coordinated agreements in this paper we investigate underlining factors explaining large differences in performances when the same carbon emission reductions are achieved in different abating countries to this end we develop a new multi country general equilibrium model incorporating six countries or world regions two goods six production inputs capital mobility energy mobility and international trade meanwhile we adopt two performance indicators with carbon leakage representing environmental efficiency and carbon emission abatement costs revealing cost effectiveness our findings are as follows firstly there are large differences in performances among these unilateral climate policies as evidenced by large differences in leakage rates and carbon emission abatement costs secondly the new global climate treaties to replace the kyoto protocol should be able to induce more carbon emission reductions in countries with low carbon emission reduction costs since such setting contributes to global cost savings finally developed countries have high carbon emission abatement costs compared with large developing countries china and india in this paper implying that there should be trade off mechanisms between efficiency and equity regarding how to allocate carbon emission reductions among countries

the perils of behavior based personalization behavior based personalization has gained popularity in recent years whereby businesses offer personalized products based on consumers purchase histories this paper highlights two perils of behavior based personalization in competitive markets first although purchase histories reveal consumer preferences competitive exploitation of such information damages differentiation similar to the classic finding that behavior based price discrimination intensifies price competition with endogenous product design there is yet a second peril it emerges when forward looking firms try to avoid the first peril by suppressing the information value of purchase histories ideally if a market leader serves all consumers on day 1 purchase histories contain no information about consumer preferences however knowing that their rivals are willing to accommodate a market leader firms are more likely to offer a mainstream design at day 1 which jeopardizes differentiation based on this understanding i investigate how the perils of behavior based personalization change under alternative market conditions such as firms better knowledge about their own customers consumer loyalty and inertia consumer self selection and the need for classic designs

impacts of climate policy on the competitiveness of canadian industry how big and how to mitigate competitiveness concerns have been at the forefront of climate policy debates in canada particularly as a result of its high energy intensity and significant exposure to international markets this paper uses a dynamic computable general equilibrium model to assess the likely impacts on sectoral competitiveness that would accompany efforts to meet greenhouse gas mitigation targets that have been set by the canadian government additionally it evaluates several design mechanisms that could be used to reduce the negative competiveness impacts associated with adoption of domestic climate policies the analysis suggests that several sectors would likely face significant competiveness challenges under a reference scenario in which permits are given to emitters in lump sum however it finds that competiveness impacts can be minimized by using output based recycling of permits or by using border tax adjustments

the effects of third degree price discrimination in oligopoly retail firms and restaurants commonly offer senior citizen discounts i suspect this practice is not motivated by altruism rather the behavior can be better explained as profit maximizing price discrimination these firms are setting a low price in a market which probably has high elasticity of demand but why should the demand of senior citizens be more elastic than average one possibility is that elderly people have below average income and they would not eat out if restaurant prices were high perhaps a more plausible explanation is that retired people simply have more time on their hands to spend commuting across town to take advantage of discounts the purpose of these discounts may then be to lure senior citizens away from other restaurants rather than to get them out of the house the analysis of third degree price discrimination has a long history a c pigou 1920 joan robinson 1933 and two articles on the subject have recently appeared in this review richard schmalensee 1981 hal varian 1985 the industry structure in these analyses is monopoly but an explicit model of some form of competition is obviously needed to study discriminatory discounts meant to attract customers from rival firms and even discounts meant to get people out of the house may have an oligopoly analysis which is qualitatively different from their monopoly anlysis in this paper i present a simple duopoly model of a differentiated products industry i show that a firm s price elasticity of demand in a market can be expressed as the sum of two parts the industry demand elasticity and the cross price elasticity the first measures the tendency of consumers in a market to stay home when the price goes up the second the tendency to switch suppliers in the monopoly case in which the crossprice elasticity is zero and the collusive case in which the cross price elasticity is irrelevant discrimination between markets is due to differences in industry demand elasticity in the noncooperative oligopoly case equilibrium price differentials can be accounted for both by differences in cross price elasticity as well as differences in industry demand elasticity total industry output when the firms can discriminate between two markets is compared to what it would be if discrimination were impossible which regime has larger output depends on the sum of the adjustedconcavity condition and the elasticity ratio condition the first predominates when the rival products are poor substitutes and the firms have approximate monopoly power while the second predominates at the other extreme where the products are close substitutes and the firms have almost no market power the adjusted concavity condition compares the relative curvature of demands in the two markets and was originally discovered by robinson 1933 in her analysis of monopoly price discrimination the elasticity ratio condition compares the relative difference in industry demand elasticity between the two markets with the relative difference in cross price elasticity according to the elasticity ratio condition a discriminatory discount due to high industry elasticity of demand would be more likely to increase total output than one due to high cross price elasticity the effect of discrimination on profit is also discussed the distinction made here department of economics university of wisconsin madison madison wi 53706 this paper is a revision of part of my doctoral dissertation i am grateful to steve matthews ken judd and john panzar for guidance in this research i also thank seminar participants at wisconsin the justice department and the 1986 econometric society meetings in new orleans and the discussant martin perry the excellent comments of the referees improved the exposition of the paper

wage differentials and moonlighting by civil servants evidence from cote d ivoire and peru as part of their efforts to reduce fiscal deficits many governments have allowed public sector salaries to erode often on the assumption that government workers are overpaid vis a vis those in the private sector that assumption is tested by analyzing public private pay differentials in cote d ivoire and peru switching regressions models are estimated using full information maximum likelihood fiml and the results are compared to those obtained using ordinary least squares ols techniques the ols yields seriously biased estimates of the pay structure suggesting that public wages are higher than private wages the fiml estimates show the opposite our probit analysis also shows that the wage disadvantage of civil servants is a determinant of the greater prevalence of moonlighting among public than private employees the evidence suggests that reductions in employment rather than pay while being less palatable in the short term will be more effective in the long run

personalized pricing and quality differentiation we develop an analytical framework to investigate the competitive implications of personalized pricing pp whereby firms charge different prices to different consumers based on their willingness to pay we embed pp in a model of vertical product differentiation and show how it affects firms choices over quality we show that firms optimal pricing strategies with pp may be nonmonotonic in consumer valuations when the pp firm has high quality both firms raise their qualities relative to the uniform pricing case conversely when the pp firm has low quality both firms lower their qualities although many firms are trying to implement such pricing policies we find that a higher quality firm can actually be worse off with pp while it is optimal for the firm adopting pp to increase product differentiation the non pp firm seeks to reduce differentiation by moving in closer in the quality space while pp results in a wider market coverage it also leads to aggravated price competition between firms because this entails a change in equilibrium qualities the nature of the cost function determines whether firms gain or lose by implementing such pp policies despite the threat of first degree price discrimination we find that pp with competing firms can lead to an overall increase in consumer welfare

is it all about money an examination of the motives behind moonlighting multiple job holding is an important labour market phenomenon in this article we examine individuals motives for multiple job holding specifically we estimate an empirical model of the motivation for moonlighting assuming that individuals hold a second job for either financial or for nonpecuniary motives our results contribute to a better understanding of multiple job holding we find that multiple job holding is used by individuals as a way to deal with the financial difficulties or the increased financial commitments in their household individuals are more likely to moonlight for money in the early stages of their adult life finally individuals with more labour market experience are more likely to moonlight for pecuniary than nonpecuniary reasons

segmentation advertising and prices this paper explores the implications of market segmentation on firm competitiveness in contrast to earlier work here market segmentation is minimal in the sense that it is based on consumer attributes that are completely unrelated to tastes we show that when the market is comprised by two consumer segments and when there is sufficient variation in the per consumer costs firms need to incur to access the different consumer populations then firms obtain positive profits in symmetric equilibrium otherwise the equilibrium is characterized by zero profits as a result a minimal form of market segmentation combined with advertising cost asymmetries across consumer segments give firms an opportunity to generate positive rents in an otherwise bertrand like environment

price competition in markets with consumer variety seeking we investigate price competition between firms in markets characterized by consumer variety seeking while previous research has addressed the effect of consumer inertia on prices there exists no research on the effects of variety seeking on price competition our study fills this gap in the literature using a two period duopoly framework as in klemperer s analysis of inertial markets we show that the noncooperative pricing equilibrium in a market with consumer variety seeking may be the same as the collusive outcome in an otherwise identical market without variety seeking specifically our variety seeking model implies tacit collusion between firms in both periods unlike the inertia model of klemperer that implies tacit collusion between firms only in the second period but implies fierce price competition in the first period when consumers are assumed to have rational expectations about future prices the implied first period prices increase further which is consistent with what klemperer finds in an inertial market to summarize while our variety seeking analyses support two key results pertaining to second period prices and rational expectations previously derived for inertial markets by klemperer they depart from one key result pertaining to first period prices

taxation and wealth transmission in france abstract this paper studies inter vivos transfers and bequests in france and their relation to the french inheritance law and taxation using administrative records and a national households survey transmission behavior is highly responsive to changes in the fiscal system inter vivos gifts increased after a 1992 law made them partly tax free moreover the probability of giving to children is greater ceteris paribus if parents wealth is taxable for children the probability of receiving a gift over the life cycle increases with their permanent income the amount received increases with current income it increases or bears no relation to permanent income depending on the specification thus we find no direct support for the altruistic nor for the exchange motive these results are compatible with a model where parents transfer to the best endowed child

the shadow margins of labor market slack we use a mix of new and existing data to develop the aggregate hours gap ahg a novel measure of labor market underutilization our measure differentiates individuals by detailed categories of labor market participation and uses data on their desired work hours as a measure of their potential labor supply we show that desired hours vary widely by demographics and detailed labor force status and that the gap between desired and actual work hours is strongly positively correlated with reported search effort the aggregate hours gap suggests a more sluggish labor market recovery since the great recession than either the official unemployment rate or alternative measures of labor market underutilization modest amounts of underutilization among the part time employed and a substantial degree of underutilization among those out of the labor force account for the disparity the aggregate hours gap also does well in accounting for wage movements over our sample period

technical note personalized dynamic pricing of limited inventories prior work has investigated time and inventory level dependent pricing of limited inventories with finite selling horizons we consider a third dimension in addition to time and inventory level that the firms can use in setting their prices the information that the firm has at the individual customer level an arriving customer provides a signal to the firm which is an imperfect indicator of the customer s willingness to pay and the firm makes a personalized price offer depending on the signal inventory level and time we consider two different models full personalization and partial personalization in the full personalization model the firm charges any price it wishes given the customer signal while in the partial personalization model the firm can charge one of two prices we find that a mere correlation between the signals and customers willingness to pay is not sufficient to ensure intuitive relationships between the signal and the optimal prices we determine a stronger condition which leads to several structural properties including the monotonicity of the optimal price with respect to the signal in the full personalization model for the partial personalization model we show that the optimal pricing policy is of threshold type and that the threshold is monotonic in the inventory level and time

tanzanian formal sector workers participation in informal production a theoretical model is developed explaining formal sector workers participation in the informal sector a reduced form informal sector participation function is derived from a specific utility function a specific informal sector production function and a specific informal sector earnings function the participation function can be estimated consistently and provides a solution to the problem that informal sector wages in developing countries are hard to observe a sample of tanzanian formal sector workers is used to estimate the participation function a majority of tanzanian formal sector workers participate in informal production participation in informal production is inversely related to household income to living in dar es salaam and to being a mother with small children participation is positively related to age and multiple job holding seems to play a very different role in the transition from work to retirement in tanzania compared to industrialized countries
