testing dependence between gdp and tourism s growth rates abstract the main aim of this paper is to link the economic behaviour and statistical properties of gdp and tourism receipts growth rates through modelling the dependence to that end two developed economies such as the united kingdom non tourist oriented and spain tourist oriented and an emerging economy such as croatia tourist oriented are considered as case studies therefore a copula based garch approach is employed to describe the dependence structure between gdp and tourism receipts growth rates in this respect any causality and cointegration between tourism and gdp could justify public policies that promote a more efficient public resource allocation in the tourism industry additionally evidence of dependence between growth rates can justify the extent and direction of these policies results indicate that there is a significant asymmetric and positive dependence between tourism and gdp growth rates for the three countries studied though only for croatia is it time varying over time

new results on the relationship among risk aversion prudence and temperance abstract this note studies the relationships between different aspects of agent s preferences toward risk we show that under the assumptions of non satiation and bounded marginal utility prudence implies risk aversion imprudence implies risk loving and that temperance implies prudence intemperance implies imprudence the implications of these results for comparing risks in the cases of increase in risk increase in downside risk and increase in outer risk are discussed

tourism as a long run economic growth factor the spanish case this paper examines the role of tourism in the spanish long run economic development the tourism led growth hypothesis is confirmed through cointegration and causality testing the results indicate that at least during the last three decades economic growth in spain has been sensible to persistent expansion of international tourism the increase of this activity has produced multiplier effects over time external competitivity has also been proved in the model to be a fundamental variable for spanish economic growth from the empirical analysis it can be inferred the positive effects on income that government policy in the adequacy of supply as well as in the promotion of tourist activity may bring about

the contribution of tourism development to economic growth in the korean economy abstract this study investigates the causal relations between tourism growth and economic expansion for the korean economy by using engle and granger two stage approach and a bivariate vector autoregression var model two principle results emerge from this study first the results of a cointegration test indicate that there is no long run equilibrium relation between two series second the outcomes of granger causality test imply the one way causal relationship of economic driven tourism growth the hypothesis of tourism led economic growth is not held in the korean economy this consequence is supported by testing the sensitivity of causality test under different lag selections along with the optimal lag

exploring the relationship among co2 emissions real gdp energy consumption and tourism in the eu and candidate countries evidence from panel models robust to heterogeneity and cross sectional dependence a major criticism to the existing energy growth environment literature we notice is the selection of methodology panel estimation techniques that fail to consider both heterogeneity and cross sectional dependence across countries may cause forecasting errors the other concern related to the literature is that only a small number of studies analyze the influence of tourism on co2 emissions even though tourism sector has potential for affecting the environment to fulfill the mentioned gaps in the literature this study analyzes the relationship among carbon emissions real income energy consumption and tourism for a panel of the eu and candidate countries over the period 1995 2011 by using heterogeneous panel estimation techniques with cross sectional dependence results from the cadf and the cips panel unit root tests show that the analyzed variables become stationary at their first differences the lm bootstrap panel cointegration test indicates the presence of a long run relationship among the analyzed variables results from the ols with fixed effects the fmols the dols and the group mean estimator reveal that energy consumption contributes to the level of emissions while real income and tourism mitigate co2 emissions the emirmahmutoglu kose panel granger causality test suggests that there is one way causality running from tourism to carbon emissions and two way causality between co2 emissions and energy consumption and between real income and co2 emissions policy implications are further discussed

energy consumption and gdp in developing countries a cointegrated panel analysis in this paper we re investigate the co movement and the causality relationship between energy consumption and gdp in 18 developing countries using data for the period 1975 to 2001 recently developed tests for the panel unit root heterogeneous panel cointegration and panel based error correction models are employed the empirical results provide clear support of a long run cointegration relationship after allowing for the heterogeneous country effect the long run relationship is estimated using a full modified ols the evidence shows that long run and short run causalities run from energy consumption to gdp but not vice versa this result indicates that energy conservation may harm economic growth in developing countries regardless of being transitory or permanent

mergers and acquisitions between risk averse parties abstract this paper evaluates mergers and acquisitions ma however it may yield a higher price for the consumer moreover we show that a decentralized supply chain can be more beneficial for the parties than a centralized supply chain formed by acquisition

a minsky crisis a model is developed to illustrate hyman minsky s financial crisis theories a key assumption is that the level of wealth in the economy is determined mac roeconomically with the value of firms assets responding to the state of confidence as reflected by discounted quasi rents on capital the second assumption is that there is high substitutability between liabilities of firms and money in the public s portfolio a downward shift in anticipated profits leads wealth to contract and the public to shift portfolio preferences toward money interest rates rise leading to further dampening of expected profits and a debt deflation crisis can occur

investigating the influence of tourism on economic growth and carbon emissions evidence from panel analysis of the european union the study investigates the influence of tourism on economic growth and co2 emissions in the empirical analysis unit root and cointegration tests using panel data of european union countries from 1988 to 2009 are performed to examine the long run equilibrium relationship among tourism co2 emissions economic growth and foreign direct investment fdi results from panel cointegration techniques and fixed effects models indicate that a long run equilibrium relationship exists among these variables furthermore tourism co2 emissions and fdi have high significant positive effect on economic growth economic growth in turn shows a high significant positive impact on co2 emissions while tourism and fdi incur a high significant negative impact on co2 emissions

money and credit in a keynesian model of income determination this paper integrates the theory of money and credit derived ultimately from wicksell into the keynesian theory of income determination with assets allocated according to tobinesque principles the model deployed has much in common with the modern endogenous money school initiated by kaldor which emphasises the essential role played by credit in any real life economy since production takes time and the future is always uncertain new ground is broken methodologically because all the propositions are justified by simulations of a rigorous 60 equation model making it possible to pin down exactly why the results come out as they do one conclusion of the paper is that there is no such thing as a supply of money distinct from the money which agents wish to hold or find themselves holding this finding is inimical possibly in the end lethal to the way macroeconomics is currently taught as well as to the neoclassical paradigm itself

post keynesian stock flow consistent modelling a survey the aim of the paper is to provide an overview of the current stock ow consistent sfc literature indeed we feel the sfc approach has recently led to a blossoming literature requiring a new summary after the work of dos santos and above all after the publication of the main reference work on the methodology godley and lavoie s monetary economics an integrated approach to credit money income production and wealth the paper is developed along the following lines first a brief historical analysis investigates the roots of this class of models that can be traced as far back as 1949 and the work of copeland second the competing points of view regarding some of its main controversial aspects are underlined and used to classify the different methodological approaches followed in using these models namely we discuss i how the models are solved ii the treatment of time and its implication and ii the need or not for microfoundations these results are then used in the third section of the paper to develop a bifocal perspective which allows us to divide the literature reviewed according to both its subject and the methodology we explore various topics such as financialisation exchange rate modelling policy implication the need for a common framework within the post keynesian literature and the empirical use of sfc models finally the conclusions present some hypotheses and wishes for the possible lines of development of sfc models

change in energy related co2 carbon dioxide emissions in portuguese tourism a decomposition analysis from 2000 to 2008 abstract tourism is an activity with great potential in portugal at a time of economic crisis tourism is seen as an opportunity to boost the economy and provide sustainable economic growth this strategic path based on tourism has to be accomplished in order to make better use of the economic advantages but at the same time respecting the environment and environmental goals to which portugal is committed so it becomes important to analyze what effects contribute more to emissions in this sector as well as which tourism subsectors are more responsible for the increase of emissions the objective of this work is to identify the effects in which co2 carbon dioxide emissions in tourism can be broken down and analyzed as well as their evolution and which of them has more importance in determining emissions for that in this study a decomposition technique based on logarithmic mean divisia index was used in the 2000 2008 period for five tourism subsectors in portugal in general tourism activity is the most important effect energy mix carbon intensity and energy intensity effects also proved important

a price setting newsvendor problem under mean variance criteria the single product single period newsvendor problem with two decision variables namely price and stock quantity is considered the performance measure in addition to the expected revenue includes the variance of the income scaled with a risk parameter we present conditions for the concavity of this risk sensitive performance measure and the uniqueness of the optimal solution for both risk averse and risk seeking cases under the additive demand model and compare the results to others previously published these conditions are introduced in terms of the lost sales rate elasticity furthermore we provide numerical examples that aim to endorse the theoretical results herein explained

tax incentives and job creation in the tourism sector of brazil s sudene area summary in recent decades a significant number of developing countries have implemented fiscal incentives programs for the tourism industry as part of their regional development policies the main objective of these programs is to increase local investment and employment as tourism activities are labor intensive little evidence is available however to assess the effect of these policies on job creation in emerging markets in this paper we analyze a program of fiscal incentives introduced by the brazilian federal government in the sudene area in 2002 and in which tourism firms were eligible to participate through a difference in difference estimation we compare the change in the logarithm of local employment in the sudene municipalities before and after 2002 to the change in the same outcome in a group of municipalities that were not affected by the program although our empirical analysis does not measure the efficiency of a similar fiscal policy it is the first one in the literature to show its effectiveness it provides evidence that the fiscal incentives led to a substantial increase in tourism employment in the sudene area we find that over the period 2002 09 municipal tourism employment was on average 30 higher than in the absence of the intervention this result is robust and is not the consequence of either displacement effects or job destruction in neighboring municipalities that had not been targeted by the tax incentives we finally discuss some limitations of our analysis that might open avenues for future research in the field

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

capacitated multi item inventory systems with random and seasonally fluctuating demands implications for postponement strategies we address multi item inventory systems with random and seasonally fluctuating and possibly correlated demands the items are produced in two stages each with its own lead time in the first stage a common intermediate product is manufactured the production volumes in the first stage are bounded by given capacity limits we develop an accurate lower bound and close to optimal heuristic strategies of simple structure the gap between them evaluated in an extensive numerical study is on average only 0 45 we use the model to investigate the benefits of various delayed product differentiation postponement strategies as well as other strategic questions including i the benefits of flexible versus dedicated production facilities ii the trade off between capacity and inventory investments and iii the trade off between capacity investments and service levels

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

a note on pricing with risk aversion abstract we consider the pricing problem of a risk averse seller facing uncertain demand demand uncertainty stems from buyers valuations being privately observed by imposing very mild restrictions on the distribution of buyers valuations an increasing generalized failure rate distribution and the bernoulli utility function we show that a risk averse seller will unambiguously post a lower price than a risk neutral counterpart

effects of budgetary constraints on international tourism expenditures abstract this paper implements a logistic transition regression model to examine the relationships between gdp per capita and international tourism expenditures across countries in 2001 2010 by types of savings regimes while studies have focused on the effect of income on international tourism expenditures none consider the nonlinear smooth transition status of savings and its impacts on discretionary spending and hence expenditure on tourism the impact of income on tourism expenditures can vary under different savings regimes the results show that in a low savings regime the effect of an increase in the gdp per capita on international tourism expenditures is more pronounced in a high savings regime there is strong motivation for precautionary savings and tourism is considered a luxury therefore such spending is crowded out by an increase in savings as gdp per capita increases although international tourism expenditures also increase with gdp per capita they do so at a slower rate these findings establish an accurate understanding of the effects of savings on international tourism expenditures

optimal production and inventory policy for multiple products under resource constraints we show that a modified base stock policy is optimal for multiproduct infinite horizon production inventory systems where demand for the products is random and the products share a finite resource every period we characterize the optimal policy for the case of homogeneous products because of the difficulty in computing the optimal base stock levels for the heterogeneous case we propose a heuristic that is simple enough for practical applications we present numerical results that suggest that the heuristic yields near optimal solutions

tourism led growth hypothesis in the top ten tourist destinations new evidence using the quantile on quantile approach this paper examines the empirical validity of the tourism led growth hypothesis in the top ten tourist destinations in the world china france germany italy mexico russia spain turkey the united kingdom and the united states using the quantile on quantile qq approach and a new index of tourism activity that combines the most commonly used tourism indicators this methodology recently introduced by sim and zhou 2015 provides an ideal framework with which to capture the overall dependence structure between tourism development and economic growth the empirical results primarily show a positive relation between tourism and economic growth for the ten countries considered with substantial variations across countries and across quantiles within each country the weakest links are noted for china and germany possibly because of the limited importance of the tourism sector relative to other major economic activities in those countries important country specific policy implications may be drawn from these findings

the risk averse and prudent newsboy the effects of risk and risk aversion in the single period inventory newsboy problem are examined comparative static effects of changes in the various price and cost parameters are determined and related to the newsboy s risk aversion the addition of a random background wealth and of an increase in the riskiness of newspaper demand are also examined although many of the comparative effects generally are ambiguous some fairly simple restrictions on preferences and or risk increases are shown to lead to qualitatively deterministic results

impact of cost uncertainty on pricing decisions under risk aversion abstract this paper studies cost uncertainty in services despite the fact that the service sector has become the largest component of gross domestic products in most developed economies cost uncertainty and its impact on pricing decisions have not received much attention in the literature in this paper we first identify the root causes of cost uncertainty in services using the distinctive characteristics of services defined in the literature we show why cost uncertainty which has been widely neglected in the manufacturing dominated literature is pervasive in services next we investigate how cost uncertainty affects a risk averse service provider s pricing decisions in a make to order setting using the expected utility theory framework we show that cost uncertainty increases the optimal price whereas demand uncertainty reduces it as a result of the countervailing impacts the optimal price under risk aversion may be larger or smaller than the optimal risk neutral price next we study the problem of optimizing cost contingency in service contract pricing we show that the optimal cost contingency decreases as the profit of the contract increases even when the utility function exhibits an increasing absolute risk aversion finally we introduce various strategies to mitigate the risk of cost uncertainty observed in practice and propose new research problems

tourism development and economic growth a closer look at panels abstract this paper applies the new heterogeneous panel cointegration technique to re investigate the long run comovements and causal relationships between tourism development and economic growth for oecd and nonoecd countries including those in asia latin america and sub sahara africa for the 1990 2002 period on the global scale after allowing for the heterogeneous country effect a cointegrated relationship between gdp and tourism development is substantiated it is also determined that tourism development has a greater impact on gdp in nonoecd countries than in oecd countries and when the variable is tourism receipts the greatest impact is in sub sahara african countries additionally the real effective exchange rate has significant effects on economic growth finally in the long run the panel causality test shows unidirectional causality relationships from tourism development to economic growth in oecd countries bidirectional relationships in nonoecd countries but only weak relationships in asia our empirical findings have major policy implications

comparative statics effects independent of the utility function when do we act the same way under risk abstract to date comparative statics effects analyzed in the context of expected utility depend on the decision maker s utility function this paper presents a methodology that allows comparative statics effects to be obtained independent of the utility function for a general family of problems in other words we provide a set of conditions under which all decision makers act the same way such a methodology can be applied to relevant problems in the related literature such as the portfolio choice and the competitive firm under price uncertainty with or without the existence of a forward futures market with regards to such specific cases we show and analyze the most relevant effects produced by the variation of two or more parameters regardless of the decision maker s preferences and attitude towards risk some of these effects are illustrated numerically

exploring the effects of international tourism on china s economic growth energy consumption and environmental pollution evidence from a regional panel analysis abstract this study explores the effects of international tourism on china s economic growth energy consumption and environmental pollution as proxied by co 2 emissions in a multivariate framework using regional panel data over the period 1995 2011 our findings suggest that the tourism induced ekc hypothesis does not exist in central china and is merely weakly supported in eastern and western china however results show that tourism has a negative impact on co 2 emissions in the eastern region which contradicts with our perception to some extent panel causality tests show that the directions of causality in both short and long runs are mixed among regions nevertheless our findings reveal that tourism causally affects economic growth and co 2 emissions in the long run thus tourism led growth hypothesis is verified under all three scenarios our findings also suggest that in all three regions there is bidirectional causality between economic growth and co 2 emissions overall these results imply that low carbon tourism in china should be continuously supported which provides significant insights to policy makers at various government levels

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

the implications of tourism specialisation in the long run an econometric analysis for 13 oecd economies abstract the paper aims to illumine the longrun impact of specialisation in tourism it is shown that specialisation in tourism may not be deleterious for economic welfare once the terms of trade are considered conditions for an improvement in welfare are laid out and their existence tested by econometric methods within an almost ideal demand system formulation of tourist expenditure for 13 oecd economies the analysis uses cointegration techniques and novel sequential break dating procedures evaluated where the time dimension is small the values of the estimated parameters suggest that long run growth may not be harmed by tourism specialisation

tourism and economic development the beach disease abstract this paper analyses empirically the danger of a dutch disease effect in tourism dependent countries in the long run data on 134 countries of the world over the period 1970 2007 is used in a first step the long run relationship between tourism and economic growth is analysed in a cross country setting the results are then checked in a panel data framework on gdp per capita levels that allows to control for reverse causality non linearity and interactive effects it is found that there is no danger of a beach disease effect on the contrary tourism dependent countries do not face real exchange rate distortion and deindustrialisation but higher than average economic growth rates investment in physical capital such as for instance transport infrastructure is complementary to investment in tourism

tourism expansion tourism uncertainty and economic growth new evidence from taiwan and korea abstract this study examines the causal relationship between tourism expansion and economic growth in two asian countries taiwan and south korea an egarch m model with uncertainty factors is employed to examine the direction of causality between tourism expansion and economic growth as well as the impulse impacts of uncertainty on both variables the results indicate that the tourism led economic growth hypothesis is supported for taiwan while a reciprocal causal relationship is found for south korea the significant impacts of uncertainty on growth are also identified

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

financial development and economic growth evidence from panel unit root and cointegration tests abstract in this paper we investigate the long run relationship between financial depth and economic growth trying to utilize the data in the most efficient manner via panel unit root tests and panel cointegration analysis in addition we use threshold cointegration tests and dynamic panel data estimation for a panel based vector error correction model the long run relationship is estimated using fully modified ols for 10 developing countries the empirical results provide clear support for the hypothesis that there is a single equilibrium relation between financial depth growth and ancillary variables and that the only cointegrating relation implies unidirectional causality from financial depth to growth

corporate governance tourism growth and firm performance evidence from publicly listed tourism firms in five middle eastern countries this study explores the under researched relationship between corporate governance and firm performance in tourism companies we employ instrumental variable modelling using 2sls for publicly listed firms in five countries in the middle east board independence is found to be positively related to firm performance and stock performance suggesting that having independent directors among board members will improve overall firm performance board size shows opposing results large boards enhance firm profitability however small boards exhibit more efficient stock performance finally we support the tourism led growth hypothesis in our selected sample these findings have empirical implications for policy makers governments and academics

tourism development energy consumption and environmental kuznets curve trivariate analysis in the panel of developed and developing countries abstract the study investigates the relationship between economic growth carbon dioxide emissions tourism development energy demand domestic investment and health expenditures with an aim to test the validity of the environmental kuznets curve ekc hypothesis in the panel of three diversified world s region including east asia pacific european union and high income oecd and non oecd countries the study covers the period of last nine years i e 2005 2013 the study used the principal component analysis pca to construct tourism development index which is the amalgamation of number of tourists arrivals tourism receipts and international tourism expenditures the results validate the inverted u shaped relationship between carbon emissions and per capita income in the region the results further substantiate the following causal relationships i e i tourism induced carbon emissions ii energy induced emissions iii investment induced emissions iv growth led tourism v investment led tourism and vi health led tourism development in the region

the effect of risk sensitivity on a supply chain of mobile applications under a consignment contract with revenue sharing and quality investment abstract the paper provides a thorough investigation of the revenue sharing contract format typically used in the mobile applications apps industry the platform provider sets the level of revenue sharing and the app developer determines the investment in quality and the selling price of the app the demand for an app which depends on both price and quality investment is assumed to be uncertain so the risk attitude of the supply chain members has to be considered specifically we focus on how risk sensitive behavior of supply chain members affects chain performance the members equilibrium strategies are analyzed under different attitudes toward risk averse neutral and seeking we show that the retailer s utility function has no effect on the equilibrium strategies and suggest schemes to identify these strategies for any utility function of the developer we find that i the revenue sharing contract circumvents the double marginalization effect associated with vertical competition and therefore yields the best selling price for the customer ii a decentralized supply chain sometimes performs better than a centralized one and iii a risk seeking developer may obtain a higher expected profit than does a risk neutral developer

oil prices tourism income and economic growth a structural var approach for european mediterranean countries abstract in this study a structural var model is employed to investigate the relationship among oil price shocks tourism variables and economic indicators in four european mediterranean countries in contrast with the current tourism literature we distinguish between three oil price shocks namely supply side aggregate demand and oil specific demand shocks overall our results indicate that oil specific demand shocks contemporaneously affect inflation and the tourism sector equity index whereas these shocks do not seem to have any lagged effects by contrast aggregate demand oil price shocks exercise a lagged effect either directly or indirectly to tourism generated income and economic growth the paper does not provide any evidence that supply side shocks trigger any responses from the remaining variables results are important for tourism agents and policy makers should they need to create hedging strategies against future oil price movements or plan for economic policy developments

tourism and economic development a survey this article surveys the literature on tourism and economic development identifying the contribution that tourism can make to development including foreign currency income and employment and the costs that it entails single equation and system of equations models for estimating tourism demand are provided indicating developing countries potential to benefit from increasing expenditure on tourism but their susceptibility to deterioration in price competitiveness the main sectors of tourism supply transportation tour operators travel agents and accommodation are examined and the importance of cross country integration between firms is highlighted the article argues that many of the problems associated with the use of environmental resources for tourism stem from market failure and it considers methods for increasing sustainably the returns from them

effects of tourism on regional asymmetries empirical evidence for portugal abstract this study uses a vector autoregressive approach to estimate the regional effects of tourism in portugal with the ultimate objective of assessing tourism s role in reducing regional asymmetries we identify the locations where tourism generates higher effects for each region as well as the regions where tourism generates the strongest effects on the country s economic performance this issue is of particular interest from the side of the country s authorities since tourism is a strategic sector to promote national and regional convergence the study s findings suggest that tourism has contributed to the concentration of economic activity in the largest region of the country and to reduce the gap between the second and the third largest regions some regions benefit more from tourism located in other regions than tourism located in each region and tourism in all regions generate positive effects on the country s economic performance

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

inventory control with an exponential utility criterion a base stock policy is shown to be optimal when a dynamic version of the news vendor model is optimized with respect to an exponential utility criterion

is tourism an engine for economic recovery theory and empirical evidence abstract the purpose of this study is to examine the causal relationships between tourism development and economic growth for this purpose the dumitrescu and hurlin 2012 technique was employed to analyze the casual link between tourism development and economic growth in seven european countries the results showed that there is bidirectional causality between growth in tourism receipts and economic growth suggesting that economic growth and tourism development are interdependent and that tourism development stimulates economic growth and vice versa in these countries theoretical and practical implications are discussed within the realms of growth conservation feedback and neutrality hypotheses

an equilibrium model of the supply chain network under multi attribute behaviors analysis abstract this paper studies a supply chain network scn equilibrium model considering decision makers multi attribute behaviors from the perspective of behavioral finance in this paper an equilibrium model of an uncertain snc is constructed in which retailers choose their decisions according to their risk averse behavior loss averse behavior and regret averse behavior by using different weights to represent retailers attitudes to these three behaviors the retailers multi attribute utility functions are developed the equilibrium conditions of the manufacturers the retailers together with the network are established by the finite dimensional variational inequality formulation three numerical examples are solved in the first numerical example we illustrate the effect of each of these three behaviors on the equilibrium decisions the profits and the utilities of the decision makers in the other two numerical examples we explore the effects of changes in attitudes to these three behaviors on the equilibrium decisions profits and utilities of the decision makers the numerical results show that the equilibrium decisions are affected by each of these three behaviors very much moreover they are sensitive to the changes in attitudes to these behaviors

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

environmental performance impacts of vendor buyer coordination abstract effective coordination is a hallmark of successful supply chain management without such coordination vendors and buyers will act independently to make decisions that optimize their own objectives e g maximize their respective profits or minimize their costs this non coordinated approach is unlikely to be optimal when one considers the supply chain as a whole most vendor buyer coordination research concentrates only on an objective of minimizing total system costs but with the increasing environmental awareness in business and the general public many organizations acknowledge that strategies and practices which incorporate environmental considerations are essential to acquire a competitive advantage the objectives of this research are concerned not only with the economic impact of vendor buyer coordination on the organizations involved but also with the wider effects on society such as the effects of pollution on the environment this research demonstrates how to effectively incorporate environmental issues into vendor buyer coordination first we study the impacts of cost minimizing vendor buyer coordination models on environmental performance when compared with independent non coordinated optimization second we develop a single vendor multi buyer coordination model that includes both costs and environmental performance measures in its objective function a numerical example and a real case study show how both the total system cost and the environmental performance can be simultaneously improved

on the relationship between inventory costs and variety benefits in retailassortments consider a category of product variants distinguished by some attribute such as color or flavor a retailer must construct an assortment for the category i e select a subset variants to stock and determine purchase quantities for each offered variant we analyze this problem using a multinomial logit model to describe the consumer choice process and a newsboy model to represent the retailer s inventory cost we show that the optimal assortment has a simple structure and provide insights on how various factors affect the optimal level of assortment variety we also develop a formal definition of the level of fashion in a category using the theory of majorization and examine its implications for category profits

micro economic determinants of tourist expenditure a quantile regression approach abstract we assess the effect of the main determinants of tourist expenditure by applying both linear and quantile regression models to individual micro data collected by a survey addressed to non resident tourists who spent their holidays in sardinia during the period april october 2012 we find that in addition to income and foreign nationality tourist expenditure is crucially driven by trip related party size stay length accommodation sea and sun typology and transport modality and psychographic characteristics repeated visits and holiday motivations moreover our results indicate that the effects vary with respect to the expenditure component and the level of spending thus confirming the high complexity of the tourism product higher positive effects were found for heavy spenders in the case of foreign nationality previous visits and notoriety motivated holidays while party size and the number of visited sites contribute to reducing the level of expenditure for light spending tourists

time varying linkages between tourism receipts and economic growth in south africa the causal link between tourism receipts and gdp has recently become a major focus in the tourism economics literature results obtained in recent studies about the causal link appear to be sensitive with respect to the countries analysed sample period and methodology employed considering the sensitivity of the causal link we use rolling window and time varying coefficient estimation methods to analyse the parameter stability and granger causality based on a vector error correction model vecm when applied to south africa for the period 1960 2011 the findings are as follows results from the full sample vecm indicate that there is no granger causality between tourism receipts and gdp while the findings from the time varying coefficients model based on the state space representation show that tourism receipts have positive predictive content for gdp for the entire period with the exception of the period between 1985 and 1990 full sample time varying causality tests show bidirectional strong causal

seasonality and regional productivity in the spanish accommodation sector abstract this study quantifies the impact of peak demand and seasonality on regional productivity in the spanish accommodation sector we then identify factors affecting seasonal fluctuations and their relative contributions to regional variations in seasonality the results show that demand for accommodation in the peak season mainly determines productivity thus improving a region s attractiveness as a tourist destination is most effective for tourism based regional development in addition reducing seasonal variations has a non negligible impact on productivity a decomposition analysis reveals that providing climate independent tourist attractions and attracting business travelers are effective in reducing seasonality

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

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

a comparison of the moderating effect of tourism reliance on the economic development for islands and other countries abstract tourism is usually one of the top industries in most countries especially islands however there is some question as to whether there is a negative potential impact if a country relies too much on tourism as a means of economic development to the detriment of other industries such as manufacturing and agriculture the purpose of this paper is to examine the moderating effect of tourism reliance on the relationship between tourism development and economic development for regular countries and island economies including small island developing states sids this study uses quantile regression on panel data from the wdi database from 1995 through 2014 for all of the countries that report tourism and economic data the findings demonstrate that tourism reliance does have a moderating effect on the relationship between tourism development and economic development for all countries but mainly at higher levels of economic development

toward a macroeconomics of the medium run these days macroeconomics has become more respectable than it used to be i can remember when many economists liked to say microeconomics is not problematic but i just don t understand macroeconomics there was a definite implication that something must be wrong with macroeconomics not with the observer of course macroeconomics cannot be exact it has to work by rough analogy and empirical compromise maybe a certain raffishness is inevitable most economists work on microeconomic problems with increasing use of new microeconomic data but now it is widely understood that macroeconomics is at the heart of economics it will not do to be snooty about it this centrality will continue for the best possible reason the need to understand current events especially unfavorable ones and to formulate policies even benign neglect is a policy to

growth effects of leisure tourism and the level of economic development abstractthis study examines 1 whether leisure tourism can contribute to economic growth and 2 if it does whether its growth effects are constant across levels of economic development leisure tourism differs from business tourism in the causal relation with economic growth in addition the natural and heritage related resources for leisure tourism are limited and not reproducible this notion has a significant implication for the relationship between the growth effects of leisure tourism and the level of economic development thus the current study focuses on leisure tourism and controls for the effects of business tourism as an economy grows the growth effects of leisure tourism are expected to diminish due to a lack of continued productivity improvement in the tourism industry the empirical findings in this research reveal that leisure tourism contributes to economic growth at an early stage of economic development but its contribution becomes weaker as the economy develops
