who gains from capital market integration tax competition between unionized and non unionized countries the welfare effects of capital market integration are examined under a model of tax competition with two asymmetric countries the asymmetry is expressed through the labour market one country has a perfect labour market whereas the other country s labour market is unionized our results indicate that the welfare effects of capital market integration differ depending on whether governments are active or passive in attracting capital in the absence of active governments capital market integration benefits the country with a competitive labour market whereas it harms the unionized country capital market integration benefits both countries if governments are active and compete for mobile capital using taxes subsidies

a political economic analysis of labor migration and income redistribution we present a two country political economic model of income redistribution with internationally mobile labor migration can be exogenous and or endogenous i e determined by labor income differentials political influence is determined by the size and homogeneity of the groups where the latter can be affected by immigration we show that immigration can increase the transfers to and the income of the mobile group we also investigate the possibility of migration regulation tax transfer policy competition and coordination and finally coordination of regulation policies it is shown that the selection of any of those regimes will depend on the particular distribution of political influence among the relevant social groups in the two countries

european union commitment towards res market penetration from the first legislative acts to the publication of the recent guidelines on state aid 2014 2020 during the last three decades the european union eu commitment towards the renewable energy sources res market penetration has been very complex involving several aspects pertaining to the economic and political action of member states this paper seeks to overview the historical development of the legislative eu framework including a description of the main financial programmes established and managed by the eu directorates general moreover the work will proceed with the picture of some investment funds ad hoc created for res undertakings and managed by the european investment bank eib in collaboration with the eu or other foreign bank institutes the delicate matter of state aid is discussed paying particular attention to the transition from 1999 to the recent eu guidelines 2014 2020 as these wider scopes could lead to an effective and well functioning european energy single market focusing the attention on three case studies we have produced final remarks on the correct functioning of the eu political framework giving attention to important improvements needed at infrastructural level the eu awareness of the power grid limits that are currently recorded in europe has lead to further reforms of the legislation as shown by the new eu guidelines that will probably support member states in dealing with the infrastructure challenge

factor mobility and income redistribution in a federation abstract jurisdictions in a federation redistribute income by taxing capital and providing transfers to labor capital and labor move to earn higher returns net of taxes or gross of transfer benefits between jurisdictions in determining its redistributive policy the government for each jurisdiction thus takes into account the effects of its policy on the movement of factors from and to the jurisdiction hence the extent of redistribution depends on the mobility of factors the mobility of capital or labor leads to less redistribution than under autarky however mobility of both capital and labor may lead to more redistribution than if only capital moves as a consequence increased mobility of factors is not necessarily harmful to redistribution

two warehouse partial backlogging inventory models for deteriorating items under inflation abstract in many real life situations the practical experiences reveal that some but not all customers will wait for backlogged items during a shortage period such as for fashionable commodities or high tech products with short product life cycle the longer the waiting time is the smaller the backlogging rate would be according to such phenomenon taking the backlogging rate into account is necessary thus i here extend the models introduced in yang 2004 two warehouse inventory models for deteriorating items with shortages under inflation european journal of operational research 157 2 344 356 to incorporate partial backlogging and then compare the two two warehouse inventory models based on the minimum cost approach the study shows that the optimal solution not only exists but also is unique and model 2 is still less expensive to operate than model 1 if the factors of partial backlogging and inflationary effect are considered finally some numerical examples for illustration are provided and sensitivity analysis on some parameters is made

nash equilibria in models of fiscal competition abstract this paper analyzes nash equilibria in a simple model of an economy with jurisdictions engaging in fiscal competition small number nash equilibria in which tax rates are the strategic variables are shown not to coincide with nash equilibria in which public expenditure levels are the strategic variables

an inventory model for deteriorating items with stock dependent consumption rate and shortages under inflation and time discounting this paper derives an inventory model for deteriorating items with stock dependent consumption rate and shortages under inflation and time discounting over a finite planning horizon we show that the total cost function is convex with the convexity a simple solution algorithm is presented to determine the optimal order quantity and the optimal interval of the total cost function the results are discussed with a numerical example and particular cases of the model are discussed in brief a sensitivity analysis of the optimal solution with respect to the parameters of the system is carried out

partial backlogging inventory lot size models for deteriorating items with fluctuating demand under inflation abstract in this paper the traditional inventory lot size model is extended to allow not only for general partial backlogging rate but also for inflation the assumptions of equal cycle length and constant shortage length imposed in the model developed by moon et al moon i giri b c ko b 2005 economic order quantity models for ameliorating deteriorating items under inflation and time discounting european journal of operational research 162 3 773 785 are also relaxed for any given number of replenishment cycles the existence of a unique optimal replenishment schedule is proved and further the convexity of the total cost function of the inventory system in the number of replenishments is established the theoretical results here amend those in yang et al yang h l teng j t chern m s 2001 deterministic inventory lot size models under inflation with shortages and deterioration for fluctuating demand naval research logistics 48 2 144 158 and provide the solution to those two counterexamples by skouri and papachristos skouri k papachristos s 2002 note on deterministic inventory lot size models under inflation with shortages and deterioration for fluctuating demand by yang et al naval research logistics 49 5 527 529 finally we propose an algorithm to find the solution and obtain some managerial results by using sensitivity analyses

tax competition and the distribution of income in this paper we provide a two country two class model of asymmetric capital tax competition we show formally that poor people living in small countries can benefit from capital tax competition and therefore they are in favor of it in order to benefit from capital inflow from larger countries poor people in smaller countries accept less within country income redistribution as a consequence between country income inequality is increased by tax competition

the deterministic eoq with partial backordering a new approach previous authors have shown that if demand that cannot be filled from stock is partially backordered then using the full backordering model or assuming that all stockouts will result in lost sales can lead to substantial increases in cost relative to using a model that specifically recognizes the percentage of the stockouts that will be backordered the models that these authors developed resulted in procedures or equations that are relatively difficult to use in this paper we take a different approach to modeling the deterministic eoq with partial backordering that results in equations that are more like the comparable equations for the basic eoq and its full backordering extension

the politics of 1992 fiscal policy and european integration the internal market in europe will greatly increase the international mobility of resources how will this affect fiscal policy in different countries we consider taxation of capital in a two country model where a democratically chosen government in each country chooses tax policy higher capital mobility changes the politico economic equilibrium in two ways on the one hand it leads to more tax competition between the countries this economic effect tends to lower tax rates in both countries on the other hand it alters voters preferences and makes them elect a different government this political effect offsets the increased tax competition although not completely

social protection and political competition this paper analyses how the level of social protection is determined when its choice depends on political competition first this is done under autarky then the analysis is extended to take account of the existence of an international capital market we show that social protection never increases under international competition and in several circumstances drastically decreases

efficient migration and redistribution abstract it has often been noted that the brain drain may be abetted by highly progressive tax systems in the regions which are likely sources for emigration by those with the most income earning potential this paper presents the case in favour of such policies the underlying assumption here is that there are productivity differences between regions and that emigration of the most skilled workers from less productive regions increases the overall value of national output the problem lies in sharing these gains with the less skilled workers left behind in the low productivity region if national governments can transfer income among regions but if the transfers cannot be targeted to particular individuals then there is a trade off between equity and efficiency generous transfers redistribute the gains but tend to impede efficient migration since prospective migrants will only emigrate if their earnings net of all fiscal transfers and net of migration costs are higher in the destination region greater tax progressivity in the source region helps relax a constraint and make the trade off less difficult

commodity tax competition between member states of a federation equilibrium and efficiency we first describe regional market equilibria whereupon consumers of each region allocate their purchases of private goods between domestic and nondomestic ones according to the structure of relative prices taxes and transportation costs next regional optimal tax levels and public good quantities are derived the tax of the other region being held constant fiscal competition arises from the ability of one region in choosing its tax to alter the tax base of the other

social insurance majority voting and labor mobility abstract this paper presents a political economy approach to payroll tax competition between two countries choosing their respective systems of social insurance in a context of labor mobility it considers a class of social insurance systems which includes two interesting polar cases one where benefits are linked to contributions bismarck and one where benefits are flat beveridge the type of social insurance is chosen behind the veil of ignorance at a first constitutional stage in the second stage the generosity of social insurance as measured by the payroll tax rate is chosen by the majority given that some have the possibility to move the main results are as follows first the type of mobility namely poor vs rich has a significant impact on the second stage tax competition migration equilibrium second more bismarckian systems are not necessarily more tax competition proof third the process will result in social insurance systems with a stronger than optimal link between earnings and benefits put differently at the constitutional stage the countries will tend to adopt systems which are too bismarckian

an integrated production inventory model with imperfect production processes and weibull distribution deterioration under inflation abstract this study develops an integrated production and inventory model from the perspectives of both the manufacturer and the retailer the model assumes a varying rate of deterioration partial backordering inflation imperfect production processes and multiple deliveries the elapsed time until the production process shift is assumed to be arbitrarily distributed the discounted cash flow and classical optimization technique are used to derive the optimal solution a numerical example including the sensitivity analysis is given to validate the results of the production inventory model the integrated decision results in lower optimal joint cost compared with an independent decision by the manufacturer and the retailer

distributive implications of european integration one of the main pitfalls of european construction is undoubtedly the alleged charge that it impedes redistributive policy at the national level this charge is indeed widespread in political circles and in the medias yet it had received little attention among economists up to recently over the last few years an increasing amount of research has been devoted to that accusation or to be more neutral to that conjecture the purpose of our paper is to survey this literature we first present the conventional wisdom according to which mobility makes redistribution difficult if not impossible we also discuss the most important qualifications to this result and the solutions that are generally advocated and that imply some sort of cooperation in a second part we consider a different issue that of redistribution across countries it assumes the existence of some supranational government which is not trivial in addition informational differences between the national and the supranational governments are shown to play a crucial role

planning for shortages net present value analysis for a deteriorating item with partial backlogging abstract this paper develops inventory models to help answer strategic questions concerning whether planning for shortages offers financial benefits a production inventory system producing a deteriorating product in batches at a finite production rate with partial backordering is considered customers pay a deposit when placing a backorder backordered items receive a discount on the sales price as lost sales may lead to customers not returning the demand rate may depend on the fraction of lost sales we develop a cash flow based profit maximising net present value npv model without the inventory cost parameters commonly used in this context unit holding cost unit backorder cost unit deterioration cost and unit lost sales cost the model finds the optimal inventory policy just like npv models that discount the traditional parameters but has the advantage of not needing to estimate the value of the traditional parameters it is shown that in models based on discounting the traditional parameters the parameters are not exogenously determinable but are non trivial functions of non financial endogenous system parameters such as the production rate annual demand rate and backorder rate extensive numerical experiments illustrate how cash flow npv models provide insights into the value of planning for shortages and strategic choices about the design of the production inventory system it also provides insight into the classical problem of how to interpret unit backorder cost and unit lost sales cost the study indicates that these insights cannot be reliably obtained from npv models based on discounting unit backorder costs and unit lost sales costs

two warehouse partial backlogging inventory models with three parameter weibull distribution deterioration under inflation abstract in many inventory systems the effects of deterioration of physical goods have drawn much attention of various researchers in recent years the more the deterioration is the more the order quantity would be according to such consideration taking the deterioration rate into account is necessary thus in this paper i develop the two warehouse partial backlogging inventory model introduced in yang 2006 to incorporate three parameter weibull deterioration distribution the objective is to derive the optimal replenishment policy that minimizes the net present value of total relevant cost per unit time two alternative models are compared based on the minimum cost approach the study shows that the optimal solution not only exists but also is unique model 2 is still less expensive to operate than model 1 in the proposed model finally some numerical examples and sensitivity analysis on parameters are made to validate the results of the proposed inventory system

income redistribution and public goods provision under tax competition abstract a standard result in existing literature is that public goods are under provided under tax competition see zodrow and mieszkowski 1986 this paper shows that introducing redistribution concerns changes the result capital mobility reduces income redistribution by increasing the efficiency costs of capital taxation if public goods have positive distributional effects providing more public goods counteracts the negative effects of capital mobility moreover under the condition that labor income and capital income are positively correlated less income redistribution through capital taxation can be compensated by stronger taxation of labor income as a result a higher level of public goods is desirable if capital mobility increases

two warehouse inventory models for deteriorating items with shortages under inflation abstract in this paper the two warehouse inventory problem for deteriorating items with constant demand rate and shortages under inflation is considered in contrast to the traditional deterministic two warehouse inventory model with shortages at the end of each replenishment cycle an alternative model in which each cycle begins with shortages and ends without shortages is proposed here the optimal solution not only exists but also is unique comparing these two two warehouse inventory models the study shows that the proposed model is less expensive to operate than the traditional one in the case of the inflation rate is greater than zero hence under the consideration of inflationary effect the proposed model is less expensive finally some numerical examples for illustration are provided
