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

habits costly investment and current account dynamics abstract we analyze the current account dynamics for a small country model with habit forming consumers and costly investment the model has several empirical and policy implications i it is consistent with stylized facts regarding the effects of productivity shocks and increases in fiscal spending and regarding the savings investment co movement ii the long run effect of a temporary shock on net foreign assets is often opposite to that of a permanent shock iii under strong habit persistence the welfare dynamics are sluggish so that a beneficial tax financed fiscal policy may have a harmful hangover effect on welfare

regional capital mobility in china economic reform with limited financial integration abstract this paper assesses the changes in the regional capital mobility in china during the period of economic reform in 1978 2008 by employing a panel time varying coefficient tvp model this approach is much more suitable to model china s evolution in the regional capital mobility than a standard structural break model as china s reforms took place gradually and were often implemented over several stages using the tvp model we find that 1 china s provincial capital mobility demonstrated a moderate improvement over the sample period but worsened temporarily between 1994 and 1997 this is probably due to the government s effort to combat inflation which reduced the investment and transfers to regions 2 regions with the most developed and least developed provinces experienced higher degree of capital mobility improvement than those in the middle

on china s domestic capital mobility and the role of the government empirical evidence over 1970 2006 this article investigates capital mobility across 29 provinces in china for the period of 1970 2006 using the feldstein horioka fh approach and campbell and mankiw s consumption smoothing cs framework it also examines the role of the governments in driving provincial capital mobility if the provincial government investment is not properly separated out from the private investment the fh framework applied to the overall saving and investment private plus public is found to underestimate the private saving investment correlation and hence overstates the degree of private capital mobility compared with the cs framework that focuses on the private consumption and output both frameworks indicate strong correlation between private saving investment and private consumption output implying strong barriers in the provincial private capital flows however there is ample evidence that capital mobility has been rising over time particularly after the mid 1990s it also appears that the government facilitates capital flows through inter governmental transfers during the sample period the extent of provincial capital mobility sheds light on the ability of different provinces in diversifying idiosyncratic provincial risks the earlier findings are robust to alternative measurements of variables and model specifications

remanufacturing as a marketing strategy the profitability of remanufacturing systems for different cost technology and logistics structures has been extensively investigated in the literature we provide an alternative and somewhat complementary approach that considers demand related issues such as the existence of green segments original equipment manufacturer competition and product life cycle effects the profitability of a remanufacturing system strongly depends on these issues as well as on their interactions for a monopolist we show that there exist thresholds on the remanufacturing cost savings the green segment size market growth rate and consumer valuations for the remanufactured products above which remanufacturing is profitable more important we show that under competition remanufacturing can become an effective marketing strategy which allows the manufacturer to defend its market share via price discrimination

endogenous federal grants and crowd out of state government spending theory and evidence from the federal highway aid program contrary to simple theoretical predictions existing evidence suggests that federal grants do not crowd out state government spending a legislative bargaining model with endogenous grants documents a positive correlation between grant receipts and preferences for public goods this correlation has likely biased existing work against measuring crowd out to correct for such endogeneity the model motivates instruments based on the political power of state congressional delegations exploiting this exogenous variation in grants the instrumental variables estimator reports crowd out that is statistically and economically significant this endogeneity may explain the flypaper effect a nonequivalence between grant receipts and private income jel d70 h40 h77

on savings and investment dynamics in a small open economy abstract this paper constructs a stochastic overlapping generations two country model of savings and investment under conditions of perfect international capital mobility the focus of the analysis is on the relationship between savings and investment dynamics in a small open economy in response to stochastic variations in domestic and or foreign production technologies the model is simulated under alternative specifications of the stochastic distribution governing both technologies this provides insight into the very complicated nature and rich diversity of possible relationships between savings and investment dynamics

capital mobility for developing countries may not be so high abstract international capital flows to developing countries have taken on considerable policy importance in recent years there is disagreement however about whether financial capital mobility has become so high that developing countries have little ability to sterilize capital flows this paper reviews several popular methods of estimating the degree of capital mobility for developing countries and shows that they are subject to potentially important upward biases due to inappropriate assumptions concerning the roles of domestic inflation and sterilization corrections for these factors can cut estimates of capital mobility by one half or more

the effects of partisan alignment on the allocation of intergovernmental transfers differences in differences estimates for spain abstract in this paper we test the hypothesis that municipalities aligned with upper tier grantor governments i e controlled by the same party will receive more grants than those that are unaligned we use a rich spanish database which provides information on grants received by nearly 900 municipalities during the period 1993 2003 from three different upper tier governments i e central regional and upper local since three elections were held at each tier during this period we have enough within municipality variation in partisan alignment to provide differences in differences estimates of the effects of alignment on the amount of grants coming from each source moreover the fact that a municipality may simultaneously receive grants from aligned and unaligned grantors allows us to use a triple differences estimator which consists of estimating the effects of changing alignment status on the change in grants coming from the aligned grantors relative to the change in grants coming from the unaligned ones the results suggest that partisan alignment has a sizeable positive effect on the amount of grants received by municipalities for example with majority governments at the two layers aligned municipalities receive over 40 more grants than unaligned ones

international capital mobility what do national saving investment dynamics tell us abstract we interpret the relationship between national saving and investment in the long run as reflecting a solvency constraint and interpret the ease with which a country can run current account imbalances in the short run before it has to ultimately reverse the transaction at some future date to satisfy the solvency constraint as being positively related to the degree of international capital mobility we apply panel error correction techniques to data for 20 oecd countries from 1960 to 1999 we find that saving and investment display a long run cointegration relationship that is consistent with the interpretation that a long run solvency constraint is binding for each country over time however deviations from this long run equilibrium relation have become more persistent which suggests that capital mobility has increased

evaluating the impacts of foreign direct investment aid and saving in developing countries abstract we develop an open economy model to demonstrate how saving aid and direct investment inflows affect investment under asymmetric information the model that relates a firm s net worth to investment suggests that the relative impact of these financial sources depends on a country s income level financial structure and governance infrastructure we estimate the impact of each source using panel data for 64 developing countries the results provide support for the view that net worth matters and suggest that the influence of financial systems can explain why saving investment correlations are high for developed countries and lower for developing countries

the empirics of the municipal fiscal adjustment we summarize the literature that uses the vector error correction model approach to analyze the dynamics of the municipal fiscal adjustment the international comparison between samples collected from entire countries and specific regions reveals interesting similarities but also remarkable differences the main similarities are the fulfillment of the intertemporal budget constraint the volatility of the budgetary components and the importance of the intergovernmental transfers as an adjustment instrument the most remarkable difference is the preponderant role of the own revenues in the usa probably reflecting the larger fiscal autonomy of us municipalities in most cases the large municipalities seem to be more dependent on grants than their small counterparts although this pattern is broken in japan finally partial evidence supporting the existence of moral hazard problems and the flypaper effect is provided

north south lending and endogenous domestic capital market inefficiencies abstract we develop an open economy model of intertemporal trade under asymmetric information capital market imperfections are endogenous and depend on a country s stage of economic development relative to the perfect information benchmark north south capital flows are dampened and possibly reversed and world interest rates are lower whereas riskless rates are equalized across borders the domestic loan rate is higher in poorer countries the model can be applied to a number of policy issues including the debt overhang problem the indexation of foreign public debts and the effect of income distribution on growth

the flypaper effect what happens to a state s spending when it receives an unconditional grant from the federal government the standard theoretical analysis predicts that the increase in spending will be the same as that generated by an equivalent increase in local incomes or roughly 5 10 percent for most states in contrast numerous empirical analyses have found that spending increases by much more with some estimates near 100 percent this result is known as the flypaper effect since the money appears to stick where it hits the authors review this evidence as well as other studies that find similar behavior in firms

terms of trade dynamics in asia an analysis of national saving and domestic investment responses to terms of trade changes in 14 asian ldcs abstract i estimate a three equation model of savings investment and growth on pooled time series data for 14 asian developing countries to explore terms of trade dynamic effects on the current account a terms of trade deterioration lowers aggregate saving and raises investment in the current year it also exerts a positive lagged effect on investment due to the unanticipated temporary nature of the terms of trade change the current account oscillates before returning gradually to its steady state level the model explains 65 per cent of the variance in the sample countries current accounts over the period 1962 1983

the dynamics of municipal fiscal adjustment abstract the dynamic fiscal policy adjustment of local jurisdictions is investigated empirically using a panel of more than 1000 u s municipalities over a quarter of a century distinguishing own source revenue grants expenditures and debt service the analysis is carried out using a vector error correction model which takes account of the intertemporal budget constraint the results indicate that a large part of the adjustment in response to fiscal imbalances takes place by offsetting changes in future expenditures in addition the results show that fiscal imbalances are financed to a significant extent by subsequent changes in grants decomposition of the sample according to average city population reveals that the basic pattern of fiscal adjustment is robust although intergovernmental grants play a much more pronounced role in maintaining budget balance for large cities

capital flows investment and exchange rates abstract this paper incorporates international capital flows into a two country monetary general equilibrium model of asset prices with investment and production we calculate theoretical covariances between investment the current account the exchange rate and the terms of trade these covariances depend upon the coefficient of relative risk aversion the magnitude and sign of a country s net international indebtedness other properties of tastes and technologies and the stochastic processes on disturbances to productivity and monetary growth rates international capital flows arise from changes in world wealth and its relative composition in foreign and domestic assets

the global side of the investment saving puzzle in this paper we reexamine the long standing and puzzling correlation between national saving and investment in industrial countries we apply an econometric methodology that allows us to separate idiosyncratic correlation at the country level from correlation at the global level in a major break with the existing literature we find no evidence of a long run relationship in the idiosyncratic components of saving and investment we also find that the global components in saving and investments commove indicating that they react to shocks of a global nature

international capital mobility in oecd countries the feldstein horioka puzzle revisited abstract we utilise the most recent time series techniques of dynamic ols and examine international capital mobility across 23 oecd countries we adopt the saving investment approach where the endogeneity problem is confronted our findings show that capital has been remarkably mobile in most countries over the last three decades

saving investment associations and capital mobility on the evidence from japanese regional data abstract the paper examines the magnitude of the saving retention coefficient b in a setting of known near perfect capital mobility japanese regions first we find that on total regional saving and investment rate data inclusive of regional government saving and investment the estimate of b is negative this negative relationship in the total rates across japanese regions appears to arise from the strong negative association in the government saving and investment rates second on private regional investment and saving rate data b is insignificantly different from zero this is evidence consistent with the hypothesis of feldstein and horioka economic journal 1980 that in a financially integrated economy b would be close to zero

the feldstein horioka puzzle and spurious ratio correlation abstract this study shows that the feldstein horioka puzzle resembles a spurious ratio correlation due to a common deflator pearson 1896 7 empirically the feldstein horioka specification and its counterpart with an arbitrary deflator final domestic demand give similar results monte carlo results also indicates that the slope and r 2 of the ratio regression are upward biased theoretically assuming each of the original undeflated variables are linear homogeneous functions of the deflator and random disturbances formulas for and r 2 are derived as saving and investment rates are numerically small relative to the disturbances both and r 2 are predominantly determined by the disturbances and they tend towards unity when the disturbances are close in magnitude the feldstein horioka results are therefore noisy though not entirely spurious and do not necessarily reflect a strong correlation between investment and savings

using a discontinuous grant rule to identify the effect of grants on local taxes and spending when investigating the effects of federal grants on the behavior of lower level governments it is hard to defend the handling of grants as an exogenous factor federal governments often set grants based on characteristics and performance of decentralized governments in this paper we make use of a discontinuity in the swedish grant system in order to estimate the causal effects of general intergovernmental grants on local spending and local tax rates the formula for the distribution of funds is used as an exclusion restriction in an iv estimation we find evidence of crowding in where federal grants are shifted to more local spending but not to reduced local tax rates

budget spillovers and fiscal policy interdependence evidence from the states abstract this paper formalizes and tests the notion that states expenditures depend on the spending of similarly situated states we find that even after allowing for fixed state effects year effects and common random shocks among neighbors a state government s level of per capita expenditure is positively and significantly affected by the expenditure levels of its neighbors ceteris paribus a one dollar increase in a state s neighbors expenditures increases its own expenditure by over 70 cents

the terms of trade and the current account the harberger laursen metzler effect the paper examines the effect of terms of trade changes on a small country s spending and current account assuming optimizing behavior in an intertemporal framework with perfect international capital mobility a temporary future terms of trade deterioration implies a deterioration improvement of the trade balance whereas a permanent terms of trade deterioration has an ambiguous effect depending on the rate of time preference nominal and real variables are considered via exact price indexes two periods and an infinite horizon are examined

current account dynamics and the terms of trade harberger laursen metzler two generations later this is a study of the current account dynamics resulting from the savings and investment dynamics in a small open economy which is subject to exogenous changes in its terms of trade and in world interest rates anticipated and unanticipated as well as temporary and permanent terms of trade changes have very different effects there is however a general tendency towards cycles in both savings and investment which gives rise to cycles in the current account it is shown that the classic harberger laursen metzler effect on saving of a terms of trade deterioration can have any sign for plausible parameter values both for temporary and permanent disturbances

saving growth and investment a macroeconomic analysis using a panel of countries this paper provides a descriptive analysis of the long and short run correlations among saving investment and growth rates for 123 countries over the period 1961 94 three results are robust across data sets and estimation methods i lagges saving rates are positively related to investment rates ii investment rates granger cause growth rates with a negative sign iii growth rates granger cause investment with a positive sign

the feldstein horioka puzzle revisited a monte carlo study abstract this study revisits the feldstein horioka fh puzzle by employing a variety of asymptotically efficient cointegration estimators and by using the critical values obtained from monte carlo simulations to test the hypothesis of a unit retention coefficient this leads to a lower rejection of the null than standard critical values would have implied despite ample evidence supporting the fh result there appears to be considerable heterogeneity in terms of the savings investment association and only 25 of the 23 oecd countries we examine can be characterised as open economies in the fh sense whether or not one subscribes to the fh interpretation the fh result does not appear to be robust

saving and investment in an open economy with non traded goods the authors examine a model of a small open economy in which there is free international mobility of financial capital investment in capital goods and a nontraded good such an environment is rich enough to explain several phenomena that are inexplicable in other models the authors explain why a high saving country may nonetheless borrow from abroad to finance investment they suggest an explanation of why saving and investment may be correlated even with no restrictions on trade in assets the authors also provide an optimizing model of stages in the balance of payments copyright 1989 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

de facto financial openness and capital mobility abstract this paper shows that de facto financial openness does does not increase capital mobility in developing developed countries and that capital is is not freely mobile in the most financially open developing developed countries

domestic saving and international capital movements in the long run and the short run the evidence and analysis in this paper support the earlier findings of feldstein and horioka 1980 that sustained increases in domestic savings rates induce approximately equal increases in domestic rates of investment new estimates for the post opec period 1974 79 imply that each extra dollar of domestic saving increases domestic investment by approximately 85 cents in a sample of 17 oecd countries an explicit analysis of the problems of identification and simultaneous equations bias suggests that the regression estimates are more relevant as a guide to the long run response of international capital flows than to their short run behavior coefficient estimates based on annual variations in savings and investment are subject to potentially severe simultaneous equations bias that is not present when annual observations are averaged over a decade or more and the regression is estimated with a cross country sample of these averages a portfolio model of international capital allocation that is presented in the paper indicates that the short run change in the rate of net foreign investment in response to a sustained increase in domestic saving is likely to be substantially greater than the ultimate steady state response this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item

capital mobility and the relationship between saving and investment rates in oecd countries abstract this paper considers tests that use data on saving and investment rates to determine the degree of international capital mobility two types of evidence are presented to show that a high correlation between saving and investment rates across oecd countries can be consistent with a high degree of capital mobility this evidence qualifies the conclusions of previous studies and casts doubt on the usefulness of testing hypotheses about capital mobility with data on saving and investment rates

relicensing as a secondary market strategy secondary markets in the information technology industry where used or refurbished equipment is traded have been growing steadily for original equipment manufacturers oems in this industry the importance of secondary markets has grown in parallel not only as a source of revenue but also because of their impact on these firms competitive advantage and market strategy recent articles in the press have severely criticized some oems who are perceived to be actively trying to eliminate the secondary market for their products other oems have policies that enhance their secondary markets the goal of this paper is to understand how an oem s incentives and optimal strategies vis a vis the secondary market are shaped contingent on her relative competitive advantage product characteristics and consumer preferences the critical trade off that we examine is whether the indirect benefit from maintaining an active secondary market the resale value effect can outweigh the potentially negative effect of the sales of used products at the expense of new product sales the cannibalization effect to that end we develop a durable good model where the oem can directly affect the resale value of her product through a relicensing fee charged to the buyer of the refurbished equipment we analyze the oem s strategy in both the monopoly and the duopoly cases characterize the optimal relicensing fee set by the oem and draw conclusions on the conditions that favor stimulating or deterring the secondary market this paper was accepted by candace a yano operations and supply chain management

common and country specific fluctuations in productivity investment and the current account abstract dynamic factor analysis and kalman filtering are used to construct a measure of common economic activity for the g7 countries we find that the common fluctuations are strongly associated with movements in us investment common fluctuations have substantial impact on fluctuations in both productivity and investment in these countries but very little impact on the current account country specific investment fluctuations have a significant negative impact on the current account while country specific productivity movements have little independent effect these findings are shown to be generally consistent with the predictions of a multi country dynamic model calibrated to the empirical decomposition of productivity shocks

estimating saving investment correlations evidence for oecd countries based on an error correction model abstract saving investment correlations are important stylized facts in open economy macroeconomics and indicators of capital mobility they are best estimated by an error correction model ecm because an ecm is consistent with intertemporal general equilibrium models the ecm is a synthesis of previous approaches applying the ecm to the oecd countries we find that in general saving and investment are cointegrated the ecm is more powerful in detecting cointegration than the two step engle granger procedure estimates of the saving investment correlation are robust with respect to overdifferencing we find evidence of a large country effect and an increase in capital mobility within the oecd area

productivity shocks non traded goods and optimal capital accumulation this paper considers the interaction of saving and investment in determining the current account for a small open economy subjected to productivity shocks by emphasizing the distinction between traded and non traded goods the analysis highlights the crucial role of the real exchange rate in macroeconomic adjustment our results demonstrate the importance of intertemporal substitution for determining the response of investment to anticipated productivity disturbances we also show how the correlation of movements in saving and investment following an anticipated disturbance depends critically on relative sectoral factor intensities

the dynamics of a small open economy in response to monetary fiscal and productivity shocks abstract this paper evaluates empirically the relative importance of monetary and fiscal versus technology shocks in an open economy characterized by perfect international capital mobility the variance covariance matrix of these shocks is estimated a stochastic model is used to perform numerical simulations the results show that persistent shocks to productivity can reproduce several empirical regularities including the puzzling high correlation between national saving and investment remarkably well and that monetary and fiscal shocks play a minor role

asymmetric information and agenda control the bases of monopoly power in public spending abstract a pervasive empirical finding widely known as the flypaper effect is that lump sum intergovernmental grants generate considerably greater public spending by the recipient jurisdiction than would be predicted by equivalent shifts in personal income in that jurisdiction moreover such observations are inconsistent with standard median voter models of the political process we posit a model in which it is in the interest of suppliers of a collectively provided good not to generate full information to voters about outside aid the empirical results are consistent with flypaper and suggest that voters are very poorly informed about outside grants

consumption smoothing channels in open economies abstract many intertemporal open economy macro models imply a theory of consumption smoothing channels thus we build an empirical model to analyze the intertemporal smoothing role of saving components fixed investments inventories and trade balance through the use of var impulse responses to different types of shocks we find that for the oecd countries the bulk of intertemporal smoothing has been carried out domestically via gross fixed investments and inventories but the trade balance has also played a relevant albeit volatile smoothing role we also characterize the dynamic behavior of each component the trade balance and inventories are mostly used as short run smoothing tools while fixed investment provides more and more smoothing over time we can also address some empirical puzzles such as the excess sensitivity of investment anomaly glick r rogoff k 1995 global versus country specific productivity shocks and the current account journal of monetary economics 35 159 192 and the saving investment correlation puzzle feldstein m horioka c 1980 domestic saving and international capital flows economic journal 90 314 329

consumption patterns as a measure of capital mobility evidence from some apec countries consumption patterns are used to measure capital mobility within the apec region both on a bilateral and multilateral basis two models are estimated by iv sur and ols using quarterly data for four countries the us japan canada and australia the results show that the hypothesis of perfect capital mobility is rejected and some results even indicate autarky it is argued however that the hypothesis of perfect capital mobility is unreasonable and that the consumption criterion is inappropriate because it assumes real interest equalization

the role of saving and investment in exchange rate determination under alternative monetary mechanisms abstract we argue that the demand for national currencies depends on existing payment arrangements for imports and exports therefore exchange rate movements depend on these arrangement as a result the relationship between exchange rate movements and various macroeconomic aggregates like saving and investment depend on what we call the monetary mechanism these points are explicitly demonstrated by studying two extreme monetary mechanisms one in which all payments are done with the seller s currency and one in which all payments are done with the buyer s currency

international capital mobility evidence from panel data abstract to test whether capital is internationally mobile some researchers have examined the relationship between saving and investment using time averaged data they find saving and investment to be related and conclude that capital is relatively immobile in this paper i argue that a country s intertemporal budget constraint biases results using time averaged data against finding capital mobility using annual data pooled for 21 oecd countries over the 1962 1990 period i find the estimated impact of saving on investment to be considerably smaller than previous estimates

do federal grants boost school spending evidence from title i abstract one of the federal government s main elementary and secondary education programs is title i which allocates money for compensatory education to school districts based on child poverty i use sharp changes in per pupil grant amounts surrounding the release of decennial census data to identify effects of title i on state and local education revenue and how much the program ultimately increases spending by recipient school districts i find that state and local revenue efforts initially are unaffected by title i changes but that local governments substantially and significantly crowd out changes in title i within in a 3 year period

adjustment costs in investment time preferences and the current account abstract this paper studies the effects of supply and demand shocks on the optimal investment and savings decisions of economic agents in a small open economy the two building blocks of the setup are adjustment costs in investment and a recursive time preference structure it is shown that the model can mimic certain stylized facts

on the robustness of the consumer homogeneity assumption with respect to the discount factor for remanufactured products abstract the strategic closed loop supply chain clsc literature makes the assumption that a consumer s willingness to pay wtp for a remanufactured product is a fraction of his her wtp for the corresponding new product and this fraction called discount factor is assumed to be constant among consumers recent empirical research challenges this assumption by showing that there is considerable variability in discount factors among consumers this paper considers a complex model in the clsc literature strategic remanufacturing under quality choice and compares its solution under constant discount factors with the solution that assumes a probability distribution for the discount factors which is analytically intractable and must be obtained numerically we consider quality choice and remanufacturing for both monopoly and competitive cases overall we find remarkable consistency between the results of the constant and variable discount factor models thus we make a convincing argument that the constant discount factor assumption is robust and can be used due to its tractability

domestic savings and intra national capital flows abstract regional british data on savings and investment are shown to be uncorrelated consistent with the hypothesis of perfectly mobile intra national capital flows

current accounts in debtor and creditor countries the authors reexamine a classic question in international economics what is the current account response to a transitory income shock such as a temporary improvement in the terms of trade a transfer from abroad or unusually high production to answer this question they construct a world equilibrium model in which productivity varies across countries and international borrowing and lending take place to exploit good investment opportunities despite its conventional ingredients the model generates the novel prediction that favorable income shocks lead to current account deficits in debtor countries and current account surpluses in creditor countries evidence from thirteen oecd countries broadly supports this theoretical prediction

the dynamic adjustment of local government budgets does spain behave differently the aim of this article is to analyse whether spanish municipalities adjust in response to budget shocks and if so which elements of the budget they are more likely to adjust the methodology we use to answer these questions is a vector error correction model vecm estimated with data from a panel of spanish municipalities during the period 1988 to 2006 our results confirm that spanish municipalities do indeed make adjustments in response to fiscal shocks i e the deficit is stationary in the long run we compare our results with those obtained for us and germany to evaluate if the viability of local finance depends on the institutional arrangement and to analyse how it affects the adjustment patterns we observe that grants have a more important role in the adjustment process in environments where either they have an equalization objective or where there is no clear rule that determines their distribution this fact can generate a moral hazard problem governments tend to spend more due to the exp

savings investment and international capital flows abstract the high correlation between national savings and domestic investment rateshas been interpreted as evidence that capital is not internationally mobile this paper surveys the theory and evidence on the relationship between savings and investment in a sample of 23 oecd countries a positive correlation between savings and investment rates is found in both the short and long runs however a wide variety of models generate such co movements in savings and investment in response to exogenous disturbances even under conditions of complete financial markets thus the savings investment correlation provides little evidence on the question of international capital mobility

managing new and remanufactured products we study a firm that makes new products in the first period and uses returned cores to offer remanufactured products along with new products in future periods we introduce the monopoly environment in two period and multiperiod scenarios to identify thresholds in remanufacturing operations next we focus our attention on the duopoly environment where an independent operator io may intercept cores of products made by the original equipment manufacturer oem to sell remanufactured products in future periods we characterize the production quantities associated with self selection and explore the effect of various parameters in the nash equilibrium among other results we find that if remanufacturing is very profitable the original equipment manufacturer may forgo some of the first period margin by lowering the price and selling additional units to increase the number of cores available for remanufacturing in future periods further as the threat of competition increases the oem is more likely to completely utilize all available cores offering the remanufactured products at a lower price

vignettes on the world capital market this paper is motivated by a sense that we as a profession need to understand much better than we now do how the world capital market works we seem to be genuinely schizophrenic in the ways we build models many of them are closedeconomy models in which the rest of the world does not even appear yet others of them are models of the small open economy in which hardly any degree of freedom is left for economic policy to influence events lying behind the schizophrenia is i believe a genuine ignorance on our collective part of how the world capital market

domestic determinants of the current account balance of the united states the u s economy is found to be sufficiently open to make the balance on foreign transactions an essential part of the equilibration process between saving and investment specifically over the past two decades changes in the national saving rate have increasingly been matched by changes in net foreign rather than domestic investment thus it would be counterfactual to assume in policy discussions that measures to raise the national saving rate add fully to the stock of productive capital in the united states barring only keynesian complications conversely a stimulus to domestic investment could be validated in part by drawing on foreign saving

the relationship between domestic savings and investment the feldstein horioka test using japanese regional data abstract the feldstein horioka test on capital mobility applies to japanese intra national capital flows we find that savings and investment are insignificantly correlated this suggests that the high correlation observed by the previous studies is due to the currency premium

international real business cycles we ask whether a two country real business cycle model can account simultaneously for domestic and international aspects of business cycles with this question in mind we document a number of discrepancies between theory and data the most striking discrepancy concerns the correlations of consumption and output across countries in the data outputs are generally more highly correlated across countries than consumptions in the model we see the opposite

we voted for this abstract this paper examines two institutional factors that influenced school spending in missouri during the 1970s first the retirement of a bond issue is usually accompanied by an increase in the operating tax rate which requires voter approval the retirement of a bond issue does not reduce but apparently obscures the cost of a tax increase in addition a change in assessment practices in 1975 allowed some districts to increase their effective operating rates without voter approval each of these factors led to substantial tax increases in the affected districts

saving determinants in colombia 1925 1994 abstract this paper analyzes the determinants of saving in colombia using the framework of an intertemporal model national saving partially responds to temporary changes in output according to the permanent income hypothesis higher government expenditures in relation to their permanent level are associated with lower national saving refuting the existence of ricardian equivalence the paper tests other common hypotheses in regard to saving behavior in particular we find that changes in national savings and changes in investment are perfectly correlated and that savings cause growth in the granger sense the results also indicate that increases in urbanization and age dependency have had a significantly negative effect on private saving in colombia finally we find that much of the recent reduction in private savings can be accounted by the effects of higher taxation

capacity acquisition subcontracting and lot sizing the fundamental question encountered in acquiring capacity to meet nonstationary demand over a multiperiod horizon is how to balance the trade off between having insufficient capacity in some periods and excess capacity in others in the former situation part of the demand is subcontracted while in the latter capacity that has been paid for is rendered idle capacity and subcontracting decisions arise in many economic activities ranging from production capacity planning in semiconductor fabs to leasing communication networks from transportation contracts to staffing of call centers in this paper we investigate the trade offs between acquiring capacity subcontracting production and holding inventory to satisfy nonstationary demand over a finite horizon we present capacity acquisition models with holding and without holding inventory and identify forecast robust properties of the models that restrict the dependence of optimal capacity decisions on the demand forecasts we develop algorithms for numerous practical cost structures involving variable and fixed charges and prove that they all have polynomial time complexity for models with inventory we solve a sequence of constant capacity lot sizing and subcontracting subproblems which is also of independent interest
