diversifying external linkages the exercise of irish economic sovereignty in long term perspective political independence is usually associated with an attempt to reduce economic dependency on the former dominant or colonial power for most of the early period since irish independence the attempt to reduce exposure to the uk was implemented through tariff protection and restrictions on foreign ownership inward orientation eventually ran out of steam culminating in sustained emigration and deep recession in the 1950s the genesis in the mid 1950s of ireland s low corporation tax regime facilitated later trade liberalization and diversified the economy away from the uk these developments facilitated the full convergence on uk and broader western european living standards that was eventually achieved in the 1990s from 1979 the uk would diverge from most of the rest of western europe on exchange rate policy and ireland was forced to choose between the two the resulting difficulties can be ascribed to design flaws in the european monetary project and ireland s failure to recognize the constraints that the new regime imposed

optimal dynamic pricing of inventories with stochastic demand over finite horizons in many industries managers face the problem of selling a given stock of items by a deadline we investigate the problem of dynamically pricing such inventories when demand is price sensitive and stochastic and the firm s objective is to maximize expected revenues examples that fit this framework include retailers selling fashion and seasonal goods and the travel and leisure industry which markets space such as seats on airline flights cabins on vacation cruises and rooms in hotels that become worthless if not sold by a specific time we formulate this problem using intensity control and obtain structural monotonicity results for the optimal intensity resp price as a function of the stock level and the length of the horizon for a particular exponential family of demand functions we find the optimal pricing policy in closed form for general demand functions we find an upper bound on the expected revenue based on analyzing the deterministic version of the problem and use this bound to prove that simple fixed price policies are asymptotically optimal as the volume of expected sales tends to infinity finally we extend our results to the case where demand is compound poisson only a finite number of prices is allowed the demand rate is time varying holding costs are incurred and cash flows are discounted the initial stock is a decision variable and reordering overbooking and random cancellations are allowed

optimal dynamic pricing for perishable assets with nonhomogeneous demand we consider a dynamic pricing model for selling a given stock of a perishable product over a finite time horizon customers whose reservation price distribution changes over time arrive according to a nonhomogeneous poisson process we show that at any given time the optimal price decreases with inventory we also identify a sufficient condition under which the optimal price decreases over time for a given inventory level this sufficient condition requires that the willingness of a customer to pay a premium for the product does not increase over time in addition to shedding managerial insight these structural properties enable efficient computation of the optimal policy numerical studies are conducted to show the revenue impact of dynamic price policies price changes are set to compensate for statistical fluctuations of demand and to respond to shifts of the reservation price for the former our examples show that using optimal dynamic optimal policies achieves 2 4 7 3 revenue improvement over the optimal single price policy for the latter the revenue increase can be as high as 100 these results explain why yield management has become so essential to fashion retailing and travel service industries

centralized versus decentralized provision of local public goods a political economy approach abstract this paper takes a fresh look at the trade off between centralized and decentralized provision of local public goods it argues that the sharing of the costs of local public spending in a centralized system will create a conflict of interest between citizens in different jurisdictions when spending decisions are made by a legislature of locally elected representatives this conflict of interest will play out in the legislature depending on precisely how the legislature behaves the result may be excessive public spending or allocations of public goods characterized by uncertainty and misallocation across districts the extent of the conflict of interest between districts is affected by spillovers and differences in tastes for public spending thus the relative performance of centralized and decentralized systems depends upon spillovers and differences in tastes for public spending but for different reasons than suggested in the existing literature

retail pricing and clearance sales sellers of new products are faced with having to guess demand conditions to set price appropriately but sellers are able to adjustprice over time and to learn from past mistakes additionally it is not necessary that all goods be sold with certainty it is sometimes better to set a high price and to risk no sale this process is modeledto explain retail pricing behavior and the time distribution of transactions prices start high and fall as a function of time on theshelf the initial price and rate of decline can be predicted and depends on thinness of the market the proportion of customers who are window shoppers and other observable characteristics copyright 1986 by american economic association

the effect of land use regulation on housing and land prices abstract this paper investigates the effects of land use regulation restrictiveness on house and vacant land prices in contrast to prior studies the index of restrictiveness is treated as an endogenous variable and estimated effects are allowed to vary by market setting using data on more than 100 florida cities greater regulation restrictiveness is found to increase house price and decrease land price evidence is also provided showing that more restrictiveness increases the size of newly constructed homes

assets and liabilities and scottish independence scottish independence implies an economic future that is different from remaining in the united kingdom the economic debate largely comes down to whether this would leave scots better or worse off by most measures scotland s current economic standing is very similar to that of an average uk region output per head income and unemployment are almost all exactly the same as the average uk region this is not surprising given the economic and social integration and shared institutions and is consistent with the idea of conditional convergence this suggests that after controlling for differences in institutions and other characteristics so called initial conditions countries tend to converge to similar levels of income 1 however if scotland becomes an independent nation some of the shared uk assets liabilities and institutions would need to be divided up this would change the initial conditions for scotland and the rest of the uk and therefore we would be likely to see a different economic future for both regions see barro and sala i martin 1991

strategic and operational decisions in restaurant revenue management abstract the paper addresses restaurant revenue management from both a strategic and an operational point of view strategic decisions in restaurants are mainly related to defining the most profitable combination of tables that will constitute the restaurant we propose new formulations of the so called tables mix problem by taking into account several features of the real setting we compare the proposed models in a computational study showing that restaurants with the capacity of managing tables as renewable resources and of combining different sized tables can improve expected revenue performances operational decisions are mainly concerned with the more profitable assignment of tables to customers indeed the parties mix problem consists of deciding on accepting or denying a booking request from different groups of customers with the aim of maximizing the total expected revenue a dynamic formulation of the parties mix problem is presented together with a linear programming approximation whose solutions can be used to define capacity control policies based on booking limits and bid prices computational results compare the proposed policies and show that they lead to higher revenues than the traditional strategies used to support decision makers

some economic dimensions of the sovereignty debate in quebec debt gdp and migration this paper shows that the quest for sovereignty in quebec is explained by its role as the abode for a french speaking minority in north america it notes that there was no commonly agreed legal framework for the 1980 or 1995 referendums and that the attempt to impose one in 2000 has been rejected by quebec using results from existing papers and original research the paper shows that the quest for sovereignty can have an impact on the cost of financing the public debt of the entity doing this it also shows that labour flows can be affected by the existence of a sovereignty movement this gdp would be higher if the secessionist threat had not had an impact on the size of the labour force since the early 1970s

migration housing market and labor market responses to employment shocks abstract one reason for the united states economic success is the willingness of its residents to follow jobs households decisions to move depend not only on job prospects but also on the relative cost of housing i investigate how the housing market affects the flow of workers across cities this occurs through at least two channels the relative mobility of homeowners versus renters and the relative cost of housing across markets i use homeownership rates to measure the former and use an index that measures house prices across metropolitan statistical areas msas and the price elasticity of housing supply to capture the latter to show how variation in the these housing market factors not only affects cross city migration but also the housing and labor markets i estimate a var model of migration employment wages house prices and new housing supply using annual data from 277 us msas for 1990 2006 the response functions based on labor supply and demand shocks show substantial variation when evaluated at different values of the homeownership rate the price elasticity of housing supply and relative housing prices i also allow for spillover effects in the model that reflect the impact of a labor demand shock in the nearest city

urban decline and durable housing urban decline is not the mirror image of growth and durable housing is the primary reason the nature of decline is so different this paper presents a model of urban decline with durable housing and verifies these implications of the model 1 city growth rates are skewed so that cities grow more quickly than they decline 2 urban decline is highly persistent 3 positive shocks increase population more than they increase housing prices 4 negative shocks decrease housing prices more than they decrease population 5 if housing prices are below construction costs then the city declines and 6 the combination of cheap housing and weak labor demand attracts individuals with low levels of human capital to declining cities

transition costs in secessions with a brief application to scotland this article demonstrates that the costs incurred in the process of a region becoming a sovereign state can be large enough to outweigh the long term material benefits of independence transition costs consist of transaction costs fiscal costs and the cost of uncertainty their size depends crucially on whether the politics of the transition are cooperative game theory however shows that there are incentives for threats of non cooperation and for the exercise of such threats these considerations are applied briefly to the debate about scottish independence this includes a short analysis of how transition costs can be reduced a final section inquires about possible transition benefits which can consist of solidarity

demand uncertainty and sales a study of fashion and markdown pricing the theory of clearance sales is expanded and applied to explain why markups markdowns and the frequency of sales of merchandise sold by department stores have increased dramatically in recent years and why they differ across merchandise groups tha major theme of the paper is that the growing role of fashion and product variety is an important reason for these increases and for the differences between merchandise groups the growing importance of fashion is illustrated by documenting the declining use of whites and the increasing use of colors and prints estimates of the effects of imports and technological and demographic changes on markups and markdowns are presented copyright 1988 by american economic association

a theory of urban growth in an economy experiencing endogenous economic growth and exogenous population growth we explore two main themes how urbanization affects efficiency of the growth process and how growth affects patterns of urbanization localized information spillovers promote agglomeration and human capital accumulation fosters endogenous growth individual city sizes grow with local human capital accumulation and knowledge spillovers and city numbers generally increase which we demonstrate is consistent with empirical evidence we analyze whether local governments can successfully internalize local dynamic externalities in addition we explore how growth involves real income differences across city types and how urbanization can foster income inequality most nonagricultural production in developed countries occurs in metropolitan areas the underlying reasons why economic activity agglomerates into cities localized information and knowledge spillover also make cities the engines of economic growth in an we gratefully acknowledge support of the national science foundation grants sbr 9422440 and sbr9730142 for this research the work has benefited from conversations with harl ryder on the dynamics of the model and from comments by gilles duranton and participants in seminars at brown colorado and texas austin and a presentation at an isit seminar sponsored by the centre for economic policy research and the national bureau of economic research

one money one market the effect of common currencies on trade currency unions their dramatic effect on international trade a gravity model is used to assess the separate effects of exchange rate volatility and currency unions on international trade the panel data bilateral observations for five years during 1970 90 covering 186 countries includes 300 observations in which both countries use the same currency i find a large positive effect of a currency union on international trade and a small negative effect of exchange rate volatility even after controlling for a host of features including the endogenous nature of the exchange rate regime these effects statistically significant imply that two countries sharing the same currency trade three times as much as they would with different currencies currency unions like the european emu may thus lead to a large increase in international trade with all that that entails andrew rose

dynamic pricing and ordering decisions by a monopolist this paper considers the relationship between pricing and ordering decisions for a monopolistic retailer facing a known demand function where over the inventory cycle the product may exhibit i physical decay or deterioration of inventory called wastage and ii decrease in market value called value drop associated with each unit of inventory on hand the retailer is allowed to continuously vary the selling price of the product over the cycle we introduce a notion of instantaneous margin and use it to derive profit maximizing conditions for the retailer the model explains the markdown of retail goods subject to decay it also provides guidance in determining when price changes during the cycle are worthwhile due to product aging how often such changes should be made and how such changes affect ordering intervals and quantities

revenue sharing in airline alliances we propose a two stage game theoretic approach to study the operations of an airline alliance in which independent carriers managing different reservation and information systems can collaboratively market and operate codeshare and interline itineraries in the first stage game airlines negotiate fixed proration rates to share the revenues generated by such itineraries in the second stage game airlines operate independent inventory control systems to maximize their own expected revenues we derive a revenue sharing rule that is i an admissible outcome of the first stage negotiation in the sense that no airline coalition has enough incentives to secede from the grand alliance and ii efficient for the second stage game in the sense that the decentralized system can achieve the same revenues as a central planner managing the global alliance network our numerical study shows that the proposed proration rates can lead to a significant increase in revenues with respect to other rules commonly used

catalonia and spain at the crossroads financial and economic aspects in some large european countries in recent decades economic globalization has gone hand in hand with a powerful trend to political decentralization this has been the case in the united kingdom france italy and spain in spain and after years of apparent stability the relations between catalonia and spain are experiencing troubled times this paper examines particularly the main economic effects of both the staying together and the secession scenarios following the introduction the second section reviews some aspects of the relations between catalonia and spain the third and fourth sections analyse different scenarios with a particular focus on the main issues that the secession scenario raises the fifth section contains a concluding remark

labour migration policy and constitutional change in scotland scotland is holding a referendum on independence in 2014 which implies that the scottish government would become responsible for migration policy in the event of a yes vote control over labour migration could be a vital policy tool for the scottish government influencing long run economic growth rates and demographic change this paper explores migration policy in the context of alternative constitutional outcomes for scotland it asks what scope a small economy that is intimately linked to a neighbouring larger economy has in shaping immigration policy it finds that the level of international migration to scotland is relatively low and that there are some significant differences in migrant characteristics compared to the rest of the uk ruk it also considers the political economy aspects of labour immigration through analysis of recent survey data whatever the outcome of the referendum we would argue that scotland would benefit from a more nuanced approach to immigration policies rather than the current one size fits all uk wide model

wages rents and the quality of life this study focuses on the role of wages and rents in allocating workers to locations with various quantities of amenities the theory demonstrates that if the amenity is also productive then the sign of the wage gradient is unclear while the rent gradient is positive the theory is extended to include the housing market and nontraded goods these extensions require little modification of the conclusion the empirical work on wages shows that the regional wage differences can be explained largely by these local attributes with the use of site price data implicit prices are estimated and quality of life rankings for the cities are computed

optimal starting times for end of season sales and optimal stopping times for promotional fares many industries face the problem of selling a fixed stock of items over a finite horizon these industries include airlines selling seats before planes depart hotels renting rooms before midnight theaters selling seats before curtain time and retailers selling seasonal goods such as air conditioners or winter coats before the end of the season given a fixed number of seats rooms or coats the objective for these industries is to maximize revenues in excess of salvage value when demand is price sensitive and stochastic pricing is an effective tool to maximize revenues in this paper we address the problem of deciding the optimal timing of a single price change from a given initial price to either a given lower or higher second price under mild conditions we show that it is optimal to decrease resp to increase the initial price as soon as the time to go falls below resp above a time threshold that depends on the number of yet unsold items

taxing an independent scotland if scotland were to become independent it would gain considerably more control over its tax system than it currently enjoys in this paper we consider the consequences of independence for the optimal design of a new scottish tax system an analysis which would also be of some relevance for considering the consequences for tax design of independence of other smaller nations scotland is different from the rest of the uk in some ways that are important for tax system design incomes are more equally distributed for example that is one reason why the progressive income tax currently raises less per head in scotland than in the rest of the uk it also suggests that there is less to be gained in terms of redistribution from sharply progressive taxation independence would create additional complexity for individuals and firms working or trading across borders it could also put downward pressure on tax rates and our analysis suggests that optimal tax rates in an independent scotland are likely to be lower than optimal rates in the uk as a whole at the same time the context of a substan tial budget deficit will continue to put upward pressure on tax rates

an analysis of bid price controls for network revenue management bid prices are becoming an increasingly popular method for controlling the sale of inventoryin revenue management applications in this form of control threshold or bid prices are set for the resources or units of inventory seats on flight legs hotel rooms on specific dates etc and a product a seat in a fare class on an itinerary or room for a sequence of dates is sold only if the offered fare exceeds the sum of the threshold prices of all the resources needed to supply the product this approach is appealing on intuitive and practical grounds but the theory underlying it is not well developed moreover the extent to which bid price controls represent optimal or near optimal policies is not well understood using a general model of the demand process we show that bid price control is not optimal in general and analyze why bid price schemes can fail to produce correct accept deny decisions however we prove that when leg capacities and sales volumes are large bid price controls are asymptotically optimal provided the right bid prices are used we also provide analytical upper bounds on the optimal revenue in addition we analyze properties of the asymptotically optimal bid prices for example we show they are constant over time even when demand is nonstationary and that they may not be unique

vertical fiscal externalities in a federation abstract we examine vertical fiscal externalities in a model where a state government provides a productivity enhancing public input and both the state and the central government tax wages and profits previous literature has emphasized the negative tax externality that occurs when two levels of government impose distortionary taxes on the same tax base we show that an increase in the state government s tax rate on wage income can increase federal revenues if the federal government imposes an ad valorem tax on employees wages and the demand for labour is inelastic we also show that an increase in the provision of the public input can either increase or reduce federal tax revenues leading to either under or over provision of the public input by the state government

mathematical programming for network revenue management revisited mathematical programming models for airline seat inventory control provide booking limits and bid prices for all itineraries and fare classes e l williamson airline network seat inventory control methodologies and revenue impacts ph d thesis massachusetts institute of technology cambridge ma 1992 finds that simple deterministic approximation methods based on average demand often outperform more advanced probabilistic heuristics we argue that this phenomenon is due to a booking process that includes nesting of the fare classes which is ignored in the modeling phase the differences in the performance between these approximations are studied using a stochastic programming model that includes the deterministic model as a special case our study carefully examines the trade off between computation time and the aggregation level of demand uncertainty with examples of a multi leg flight and a single hub network

competitive strategies for two firms with asymmetric production cost structures we model joint production marketing strategies for two firms with asymmetric production cost structures in competition the first firm called the production smoother faces a convex production cost and a linear inventory holding cost the second firm called the order taker faces a linear production cost and holds no inventory each firm is assumed to vary continuously over time both its production rate and its price in view of an unstable surge pattern of demand the underlying theoretical motivation is to investigate the temporal nature of the equilibrium policies of two competing firms one operating at or near capacity the production smoother and one operating significantly below capacity the order taker we characterize and compare the equilibrium strategies of the two competing firms among our results we show that if the duopolistic production smoother finds it optimal to hold inventory then he will begin the season by building up inventory continue by drawing down inventory until i

scotland and small country independence the assessment this paper reviews some of the issues consequent on the formation of new states through secession while its particular focus relates to the potential withdrawal of scotland from the united kingdom it discusses preference heterogeneity as a potential cause of the break up of states relating that to recent developments in the economics of identity it examines some macroeconomic issues particularly debt and currency and reflects on how these might influence secession it examines alternatives fiscal decentralization to secession and considers the strategies that those arguing for and against secession may deploy it also explains the structure of this issue explaining how the different contributions come together

economics and identity this paper considers how identity a person s sense of self affects economic outcomes we incorporate the psychology and sociology of identity into an economic model of behavior in the utility function we propose identity is associated with different social categories and how people in these categories should behave we then construct a simple game theoretic model showing how identity can affect individual interactions the paper adapts these models to gender discrimination in the workplace the economics of poverty and social exclusion and the household division of labor in each case the inclusion of identity substantively changes conclusions of previous economic analysis

optimal pricing strategies for new products in dynamic oligopolies this paper deals with the determination of optimal pricing policies for firms in oligopolistic markets the problem is studied as a differential game and optimal pricing policies are established as nash open loop controls cost learning effects are assumed such that unit costs are decreasing with cumulative output discounting of future profits is also taken into consideration initially the problem is addressed in a general framework and we proceed to study some specific cases that are related to models presented in recent literature three basic classes of sales dynamics are analyzed competition with price effects only competition with price as well as adoption effects and competition with adoption effects only in some cases it turns out that results which hold for the monopoly case carry over to the multi firm case in the sense that the qualitative structure of optimal pricing strategies is the same in the monopoly and the oligopoly cases however due to competitive interdependencies differences certainly exist in the levels as well as the rates of change of optimal prices

why are products sold on sale explanations of pricing regularities this paper reports on interesting changes in markdown pricing practices over time and differences in the pricing within a product line the price discrimination and the uncertainty hypotheses appear to better explain the data than the peak load hypothesis fashion has become more important over time and appears to explain the greater seasonal variation in retail apparel prices in recent years differences in uncertainty also explains differences in the pricing of different types of men s dress shirts

the energy sector in scotland s future the energy sector accounts for 15 20 per cent of scottish gdp it is highly capital intensive and maintaining production especially of oil and gas will absorb a large share of business investment over the next 5 10 years the volatility of revenues from the sector means that an independent scotland will face much greater difficulties in macro economic management than as part of the uk attempting to fix its exchange rate either to the pound sterling or the euro without a system of compensating fiscal transfers will put the burden of adjustment on factor mobility and incomes scotland could use a sovereign wealth fund as a stabilizing instrument but it is starting from a much worse position than norway and would need to reduce current government spending to build up the fund the prospects for exporting gas and electricity to the rest of the uk depend upon the terms of access to markets it seems unlikely that integrated great britain markets will survive in their current form large exports will continue but the net terms of trade will probably be less favourable to scotland than at present

local amenities and life cycle migration do people move for jobs or fun abstract do households move for jobs or fun and where do they go when they move we address these questions using the 1970 2000 us census based on a panel of quality of life and business environment measures households prefer msas in warm coastal areas and non metropolitan locations while firms prefer large growing cities in addition cities with improving business environments acquire increasing shares of workers especially workers with high levels of human capital cities with improving consumer amenities become relatively more populated by retirees further analysis of individual level migration decisions indicates that regardless of marital status young highly educated households tend to move towards places with higher quality business environments this tendency is especially pronounced among highly educated couples who are more subject to job market co location problems in contrast regardless of education couples near retirement tend to move away from places with favorable business environments and towards places with highly valued consumer amenities these patterns help explain why areas unattractive to both households and business have struggled as with upstate new york while the sun belt and other regions are thriving

a taxonomy and research overview of perishable asset revenue management yield management overbooking and pricing this paper proposes the term perishable asset revenue management to denote the field that combines the areas of yield management overbooking and pricing for perishable assets after summarizing the characteristics common to problems in this field the paper discusses the objectives and constraints faced by decision makers then it offers a comprehensive taxonomy with 14 different elements and reviews the research that has been done related to each element finally it suggests some important areas of future research that can help bridge the gap between theory and application

cluster sample methods in applied econometrics inference methods that recognize the clustering of individual observations have been available for more than 25 years brent moulton 1990 caught the attention of economists when he demonstrated the serious biases that can result in estimating the effects of aggregate explanatory variables on individual specific response variables the source of the downward bias in the usual ordinary least squares ols standard errors is the presence of an unobserved state level effect in the error term more recently john pepper 2002 showed how accounting for multi level clustering can have dramatic effects on t statistics while adjusting for clustering is much more common than it was 10 years ago inference methods robust to cluster correlation are not used routinely across all relevant settings in this paper i provide an overview of applications of cluster sample methods both to cluster samples and to panel data sets

computing approximate nash equilibria in general network revenue management games abstract computing optimal capacity allocations in network revenue management is computationally hard the problem of computing exact nash equilibria in non zero sum games is computationally hard too we present a fast heuristic that in case it cannot converge to an exact nash equilibrium computes an approximation to it in general network revenue management problems under competition we also investigate the question whether it is worth taking competition into account when making network capacity allocation decisions computational results show that the payoffs in the approximate equilibria are very close to those in exact ones taking competition into account never leads to a lower revenue than ignoring competition no matter what the competitor does since we apply linear continuous models computation time is very short

economic aspects of constitutional change the case of belgium is belgium threatened by secession in this article we highlight why belgium is unlikely to experience the secession of flanders and investigate belgium s journey to federalism we first call upon tools provided by economic theory then we turn to facts first having a look at belgium s history and second presenting the six reforms of the state which occurred between 1970 and 2013 progressively increasing the autonomy of belgian regions and communities and making belgian federalism an evolutionary maybe endless repeated game whose players have different strategies an offensive one for the north and a conservative one for the south then we examine the contemporary dangers and discuss the outcome of belgian game from the point of view of fiscal federalism and subsidiarity

vertical externalities in tax setting evidence from gasoline and cigarettes abstract a common feature of federal systems is that tax bases are joint property consequently state and federal tax setting decisions are interdependent our aim here is to put forward a rudimentary theoretical analysis of this phenomenon and to use the theory as a framework for econometrically estimating the magnitude of the responses we find that when the federal government increases taxes there is a significant positive response of state taxes for example a 10 cent per gallon increase in the federal tax rate on gasoline leads to a 3 2 cent increase in the state tax rate

airline seat allocation with multiple nested fare classes this paper addresses the problem of determining optimal booking policies for multiple fare classes that share the same seating pool on one leg of an airline flight when seats are booked in a nested fashion and when lower fare classes book before higher ones we show that a fixed limit booking policy that maximizes expected revenue can be characterized by a simple set of conditions on the subdifferential of the expected revenue function these conditions are appropriate for either the discrete or continuous demand cases these conditions are further simplified to a set of conditions that relate the probability distributions of demand for the various fare classes to their respective fares the latter conditions are guaranteed to have a solution when the joint probability distribution of demand is continuous characterization of the problem as a series of monotone optimal stopping problems proves optimality of the fixed limit policy over all admissible policies a comparison is made of the optimal solutions

a multiproduct dynamic pricing problem and its applications to network yield management a firm has inventories of a set of components that are used to produce a set of products there is a finite horizon over which the firm can sell its products demand for each product is a stochastic point process with an intensity that is a function of the vector of prices for the products and the time at which these prices are offered the problem is to price the finished products so as to maximize total expected revenue over the finite sales horizon an upper bound on the optimal expected revenue is established by analyzing a deterministic version of the problem the solution to the deterministic problem suggests two heuristics for the stochastic problem that are shown to be asymptotically optimal as the expected sales volume tends to infinity several applications of the model to network yield management are given numerical examples illustrate both the range of problems that can be modeled under this framework and the effectiveness of the proposed heuristics the results provide several fundamental insights into the performance of yield management systems

constitutional change and inequality in scotland what scope does a sub national economy have to affect the level of inequality does a policy menu consistent with the theories of fiscal federalism provide for an ability to affect inequality measures or does this ability require the powers of a nation state in this paper we discuss these questions in the context of the debate around the scottish independence referendum in which inequality has played a prominent role and ask whether independence further devolution or simply different policies under the current constitutional framework are capable of helping scotland make the transition to a less unequal income distribution we provide a series of estimates of the impact of different policy choices upon inequality in scotland and discuss inequality reduction in the context of different constitutional options

comments on pricing research in marketing the state of the art rao s paper provides an account of recent research published in the marketing literature on the subject of pricing the paper contains an impressive bibliographic survey however the formal model proposed by the author as a framework for classifying and assessing the advances and needs in this area of marketing science is rather limited a major shortcoming of this model which appears to epitomize the marketing literature on pricing is the treatment of prices and quantities as unidimensional in other words the model implicitly assumes that purchases of the product under consideration can be characterized by a scalar quantity denoting the number of units purchased while the pricing of any such purchase is determined by a uniform unit price this restriction severely limits the pricing strategies and product types that can be addressed within such a framework for example it excludes two part tariffs and important classes of products involving metered usage service contracts etc in spite of these deficiencies i found the paper very educational its primary value is in highlighting the main research directions of pricing in the marketing literature and in conveying the importance of various pricing issues from the perspective of a leading marketing scientist taking rao s survey as a reference point i will attempt in the remainder of this discussion to examine the marketing perspective on pricing versus the approach prevailing in the economics literature dealing with pricing issues in particular i will try to identify some strengths and weaknesses of these approaches and to suggest possibilities for cross fertilization between the two disciplines with a few possible exceptions it is fair to say that the marketing literature on pricing typically focuses on developing pricing strategies for the firm and therefore treats prices as control variables the economics literature on the other hand approaches pricing from the perspective of industrial organization theory its primary objectives are to

unaffordable housing and local employment growth evidence from california municipalities it is widely believed that unaffordable housing could drive businesses away and thus impede job growth however there is little evidence to support this view this paper presents a simple model to clarify how housing affordability is linked to employment growth and why unaffordable housing could negatively affect employment growth the paper then investigates this effect empirically using data on california municipalities for various reasons a simple correlation between unaffordable housing and employment growth cannot be interpreted as causal several empirical strategies are employed to identify the causal effect of unaffordable housing on employment growth the estimation results provide consistent evidence that unaffordable housing indeed slows local employment growth

lease expiration management for a single lease term in the apartment industry abstract lease expiration management lem in the apartment industry aims to control the number of lease expirations and thus achieve maximal revenue growth we examine rental rate strategies in the context of lem for apartment buildings that offer a single lease term and face demand uncertainty we show that the building may incur a significant revenue loss if it fails to account for lem in the determination of the rental rate we also show that the use of lem is a compromise approach between a limited optimization where no future demand information is available and a global optimization where complete future demand information is available we show that the use of lem can enhance the apartment building s revenue by as much as 8 when the desired number of expirations and associated costs are appropriately estimated numerical examples are included to illustrate the major results derived from our models and the impact on the apartment s revenue of sensitivity to the desired number of expirations and associated costs

monopolist pricing with dynamic demand and production cost this paper deals with pricing of a new product over time by a monopolist who maximizes the discounted profit stream the interdependency of cost and demand on cumulative production makes the problem inherently dynamic cost is assumed to be declining with cumulative production learning curve effect while demand is a function of price and cumulative sales representing word of mouth and saturation effects the paper addresses this problem in a general framework that includes several previous results as special cases and provides new insights in other situations while the learning curve and word of mouth effect cause prices to be lower than the price that maximizes immediate revenues the saturation factor has the opposite effect the price path over time is affected by these factors and the interest rate we characterize the price path under several different situations and interpret the results for policy guidelines
