optimal control and differential game models of military expenditure in less developed countries abstract this paper presents optimal control and differential game models of military expenditure in less developed countries we emphasise the strategic interconnections between aggressive neighbours and explicitly stress the optimal resource allocation problem between civilian and military expenditure a major innovation of the analysis is to analyse the asymmetric reaction functions of the two agents and the formalisation of the stylised fact that most ldc arms races have taken place between participants of unequal size

conform or challenge adjustment strategies of sanction torn companies the literature on sanctions often neglects the role of domestic firms in sender states although sanctions only have a real economic effect when senders firms reduce their activities on the target s market in contrast sanctions avoidance and increasing investments in the target country the observed behaviour of many companies facing the eu sanctions against russia imposed in 2014 mitigate the impact of these restrictive measures while sanctions increase the political risk for companies they also offer economic opportunities and previous studies could not settle the debate on which factor prevails by evaluating responses from british french german italian and polish enterprises to an online survey distributed in 2017 we analyse at the firm level how sanction torn companies adjust to new political orders and what drives their strategic decisions we find evidence that resource dependency induces strategies that challenge sanction policies in particular non fungible assets in the target country incentivise companies to further increase their engagement these defiance strategies diminish the real economic effect of sanctions and generate a new economic equilibrium which has negative long term implications on the choice set of policymakers to further pursue the imposition of sanctions and which even outlasts the lifting of these restrictive measures

conflict cooperation and commerce the effect of international political interactions on bilateral trade flows the public choice approach to political economy is employed to gain insight into the connection between international politics and trade flows a model is constructed in which importers are assumed to be rational utility maximizers who seek to satisfy international security as well as economic welfare objectives this model of bilateral trade flows reflects contemporary theory in the field of international economics and it explicitly incorporates the general foreign policy orientation of importers among its determinants the model is tested in 16 annual crosssectional estimations 1960 75 for a complete network of 25 countries the findings show considerable support for the hypothesis that trade flows are significantly influenced by broad political relations of amity and enmity between nations the author concludes that nations adjust trade ties to satisfy security as well as economic welfare goals and that a formal political economy of trade should reflect this fact

military spending and stochastic growth abstract this study examines capital accumulation military spending arms accumulation and output growth in a stochastic endogenous growth model the analysis shows that higher lower growth in foreign military spending leads to faster slower economic growth in the home country if the home country s intertemporal substitution elasticity in consumption is smaller larger but more volatility in foreign military spending can lead to higher economic growth in the home country when its intertemporal substitution elasticity is large in addition shocks to output production may stimulate economic growth

sports sentiment and stock returns this paper investigates the stock market reaction to sudden changes in investor mood motivated by psychological evidence of a strong link between soccer outcomes and mood we use international soccer results as our primary mood variable we find a significant market decline after soccer losses for example a loss in the world cup elimination stage leads to a next day abnormal stock return of 49 basis points this loss effect is stronger in small stocks and in more important games and is robust to methodological changes we also document a loss effect after international cricket rugby and basketball games this paper employs a novel mood variable international soccer results to investigate the effect of investor sentiment on asset prices using a cross section of 39 countries we find that losses in soccer matches have an economically and statistically significant negative effect on the losing country s stock market for example elimination from a major international soccer tournament is associated with a next day return on the national stock market index that is 38 basis points lower than average we also document a loss effect after international cricket rugby and basketball games on average the effect is smaller in magnitude for these other sports than for soccer but is still economically and statistically significant we find no evidence of a corresponding effect after wins for any of the sports that we study controlling for the pre game expected outcome we are able to reject the hypothesis that the loss effect after soccer games is driven by economic factors such as reduced productivity or lost revenues we

investment the current account and the relative price of non traded goods in a small open economy abstract this paper incorporates traded and non traded investment expenditure into an infinite horizon setting with optimizing economic agents extending previous research that has incorporated traded and non traded investment into a two period setting the paper analyzes the dynamic adjustment of the relative price of non traded output the market price of capital and the current account following exogenous shocks to the system the exogenous shocks considered by the paper include permanent transitory and anticipated changes in an income tax and an investment subsidy as well as changes in the level of government purchases of traded and non traded output

anticipated foreign military threat arms accumulation and the current account in a small open economy this paper examines the effects of an anticipated foreign military threat on consumption the home weapons stock and net foreign asset position in a small open economy if the utility function is separable between butter and guns the economy decreases both butter and guns when the news arrives accumulates foreign assets prior to the foreign threat realization and increases guns as the foreign threat realizes if the utility function is nonseparable between butter and guns the economy may have two dynamic responses the first is similar to the separable case except that consumption exhibits a discrete jump when the foreign threat realizes the second is that the economy increases both butter and guns on impact decumulates foreign assets prior to the foreign threat implementation but either increases or decreases guns as the foreign threat realizes

the impact of military burden on long run growth and welfare abstract this paper presents an endogenous growth model to examine how a government s resource allocation between the defense and non defense sectors will govern both economic growth and social welfare we demonstrate that there exists an optimal defense expenditure share that maximizes the economic growth rate but this rate is smaller than the welfare maximizing share this result can be viewed as a possible vehicle to explain why in many developing countries arms limitation and disarmament negotiations usually have low performance even failing

u s policy toward foreign direct investment foreign investment policy is an increasingly important part of overall foreign policy the authors investigate the substance of u s outgoing foreign direct investment ofdi and incoming foreign direct investment ifdi policy in terms of a small set of policy values and process factors the policy values are domestic prosperity national autonomy and national security the process factors are ideological consonance impact transparency the diffusion and concentration of perceived costs and benefits and the political capacity of groups and institutions these considerations illuminate the relative stability in both areas of policy since world war ii and help to explain the changes that did take place the paper concludes with a forecast that despite the oft heard prediction that economic nationalism is on the increase u s policies toward foreign investment will remain much the same during the eighties as they have been since world war ii

the arms trade and the stability of regional arms races abstract arms sales to countries involved in regional conflicts raise a range of pressing policy issues this paper models the interaction between two potentially hostile countries who spend their national income on arms imports and consumption goods their welfare depends on consumption and military security military security is a function of relative arms stocks and depends on the relative advantages of aggressive and defensive strategies we examine the dynamic game for noncooperative and regional arms control regimes an innovation of the paper is the inclusion of the price of arms which proves to have a major effect on the stability of arms races

market efficiency of brazilian exchange rate evidence from variance ratio statistics and technical trading rules abstract this study utilizes the variance ratio test to examine the behavior of brazilian exchange rate we show that adjustments for multiple tests and a bootstrap methodology must be employed in order to avoid size distortions we propose a block bootstrap scheme and show that it has much nicer properties than the traditional chow denning chow k v denning k c 1993 a simple multiple variance ratio test journal of econometrics 58 3 385 401 multiple variance ratio tests overall the method proposed in the paper provides evidence refuting the random walk behavior for the brazilian exchange rate for long investment horizon but consistent with the random walk hypothesis for short run horizon additionally we also test for the predictive power of variable moving average vma and trading range break trb technical rules and find evidence of forecasting ability for these rules nonetheless the excess return that can be obtained from such rules is not significant suggesting that such predictability is not economically significant

imported input price and the current account in an optimizing model without capital mobility abstract this paper analyses the effect of an oil price increase in an economy which cannot borrow in the international capital markets current account surpluses and deficits are matched by reserve changes at the central bank it is shown in an optimizing setup that an unanticipated oil price increase worsens the current account and lowers the real interest rate contrary to models which assume perfect capital markets

military expenditures and economic growth in less developed countries an augmented model and further evidence a study of the impact of military expenditures on economic growth and development examines the differences in the results of previous studies which led to contradictory conclusions the authors find that these differences are due to sample variations specificational choices and the different time periods examined the data indicate that there is no consistent statistically significant connection between military spending and economic growth augmentation of the models suggests that military expenditures neither help nor hurt economic growth to any significant extent 2 tables

effects of an anticipated expansion in international public goods on public capital accumulation abstract this paper presents a generic model to include public capital accumulation and the services of international public goods provided by a neighbor country it examines the long run and short run responses of private and public capital accumulation in the home country to an anticipated increase in international public goods it is found that the home economy in effect cuts its public capital stock but keeps an unchanged private capital stock in the long run when a neighbor commits itself to expanding the stock of public goods in the future the key factor determining the short run responses of the home country is the extent to which it will match its government spending with a neighbor country s policy which is associated with the relative difference between the marginal utility of consumption and that of home public capital affected by an increase in international public goods

currency substitution and the real exchange rate the utility maximization approach abstract this paper studies the currency substitution hypothesis with rational expectations in terms of a sidrauski type model where domestic and foreign money enter the utility function it shows that contrary to liviatan 1981 the approach does not necessarily contradict calvo and rodriguez 1977 furthermore the impact of monetary stabilization policy is fully characterized with flexible and pre fixed rates for an extension of dornbusch and mussa 1975 a brief analysis of the optimal quantity of money is also provided

patterns in stock market movements tested as random number generators this paper shows that tests of random number generators rngs may be used to test the efficient market hypothesis emh it uses the overlapping serial test ost a standard test in rng research to detect anomalous patterns in the distribution of sequences of stock market movements up and down our results show that most stock markets exhibit idiosyncratic recurrent patterns contrary to the efficient market hypothesis also that ost detects a different kind of non randomness to standard econometric long and short memory tests exposure of these anomalies should contribute to making markets more efficient

a dynamic model of capital and arms accumulation how does competitive arms accumulation affect investment and capital accumulation in a dynamic optimization framework including both investment and military spending we find that when the utility function is separable between consumption and the weapon stocks an unanticipated rise in current military threat reduces current investment and an anticipated rise in future military threat stimulates current investment but when the utility function is nonseparable between consumption and the weapon stocks a current military threat may not decrease the short run investment in the long run capital accumulation is independent of the military conflicts among countries regardless of the form of the utility function

good day sunshine stock returns and the weather psychological evidence and casual intuition predict that sunny weather is associated with upbeat mood this paper examines the relationship between morning sunshine in the city of a country s leading stock exchange and daily market index returns across 26 countries from 1982 to 1997 sunshine is strongly significantly correlated with stock returns after controlling for sunshine rain and snow are unrelated to returns substantial use of weather based strategies was optimal for a trader with very low transactions costs however because these strategies involve frequent trades fairly modest costs eliminate the gains these findings are difficult to reconcile with fully rational price setting

the determinants of military expenditures in developing countries abstract this paper first discusses the results of various quantitative studies of the impact of military spending on economic growth in developing countries it concludes that there is little doubt that this impact is generally negative the paper then proceeds to consider the main factors influencing the level of military expenditure itself the analysis is developed from a conceptual matrix covering the national regional and global levels each being divided into political military and economic aspects the quantitative analysis based on cross country regressions for the period 1978 to 1980 indicates that differences among developing countries in the relative size of their military burdens reflect a complex of factors both domestic regional and global and both political military and economic

nonlinearity data snooping and stock index etf return predictability abstract this paper examines daily return predictability for eighteen international stock index etfs the out of sample tests are conducted based on linear and various popular nonlinear models and both statistical and economic criteria for model comparison the main results show evidence of predictability for six of eighteen etfs a simple linear autoregression model and a nonlinear in variance garch model but not several popular nonlinear in mean models help outperform the martingale model the allowance of data snooping bias using white s reality check also substantially weakens otherwise apparently strong predictability

reversal of fortunes democratic institutions and foreign direct investment inflows to developing countries does increased democracy promote or jeopardize foreign direct investment fdi inflows to less developed countries we argue that democratic institutions have conflicting effects on fdi inflows on the one hand democratic institutions hinder fdi inflows by limiting the oligopolistic or monopolistic behaviors of multinational enterprises facilitating indigenous businesses pursuit of protection from foreign capital and constraining host governments ability to offer generous financial and fiscal incentives to foreign investors on the other hand democratic institutions promote fdi inflows because they tend to ensure more credible property rights protection reducing risks and transaction costs for foreign investors hence the net effect of democracy on fdi inflows is contingent on the relative strength of these two competing forces our argument reconciles conflicting theoretical expectations in the existing literature empirical analyses of fifty three developing countries from 1982 to 1995 substantiate our claims we find that both property rights protection and democracy related property rights protection encourage fdi inflows after controlling for their positive effect through property rights protection democratic institutions reduce fdi inflows these results are robust against alternative model specifications statistical estimators and variable measurements

how many hands to make sanctions work comparing eu and us sanctioning efforts abstract one of the core disputes in the literature on economic statecraft addresses the conditions under which multilateral sanctions are more successful than unilateral ones our game theoretic model implies that extant assessments do not sufficiently differentiate between the varying abilities of multilateral and unilateral senders in credibly threatening and carrying out sanctions we introduce a selection argument that focuses on the complex decision making process of the european union eu to impose sanctions in comparison to the united states us the institutional structure of the eu and conflicting economic interests of multiple principals make the imposition of sanctions much more difficult in addition the international organization is less accountable vis a vis the voters both mechanisms render sanction threats by the eu less credible since the united states as a unilateral sender can issue more credible sanction threats imposed us sanctions are a negative selection of cases and thus less successful than restrictive measures imposed by the eu we test these propositions with a new dataset on threatened and imposed sanctions by the european union and the united states for the period between 1989 and 2015 the empirical evidence demonstrates that eu sanctions are indeed more successful than those by the us in contrast us sanction threats are more successful than those by the eu we provide evidence for the difficulties of multilateral senders to impose sanctions by showing that eu sanctions are both less likely and less severe the more varied the economic links of the multilateral sender with the sanctioned state are

the asian crisis and calendar effects on stock returns in thailand abstract this paper systematically examines daily returns of the thai stock market index to determine whether there is evidence of calendar effects due to the day of the week the month of the year days before or after holidays and within month effects particular attention is given to the evidence of these anomalies prior to during and after the asian crisis most of the previous empirical evidence examines each of these effects in isolation the approach adopted within this paper is to start with a general model which incorporates a range of different calendar anomalies before estimating the conditional volatility models daily data from 3rd january 1995 to 29th december 2000 are used for estimation providing 1473 observations the final models are tested by comparing their forecast performance for 2001 244 observations with various models which do not include calendar effects the conclusion is that the inclusion of calendar effects improves the forecast accuracy

the wandering weekday effect in major stock markets this paper reports a wandering weekday effect the pattern of day seasonality in stock market returns is not fixed as assumed in the monday or weekend effects but changes over time analysing daily closing prices in eleven major stock markets during 1993 2007 our results show that the wandering weekday is not conditional on average returns in the previous week the twist in the monday effect nor does it diminish through the period of analysis the results have important implications for market efficiency and help to reconcile mixed findings in previous studies including the reported disappearance of the weekday effect in recent years

when are sanctions effective a bargaining and enforcement framework although a considerable literature identifies the conditions under which sanctions are more likely to be successful few studies examine the question of when sanctioning states or senders are willing to enforce their sanctions laws against their firms using a game theoretic model we argue that imposing sanctions creates a strategic dilemma for senders we demonstrate that senders often have disincentives to enforce their sanctions policies given that the restriction on economic transactions with targeted states may undermine their firms competitiveness the model indicates that sanctions are more likely to succeed when the sender s firm retains a moderate share of the target s market relative to its foreign competitors however the model also demonstrates that sanctions are likely to be imposed only when the conditions do not favor their success the empirical implications of the model are tested using the threat and imposition of economic sanctions ties data set

an optimizing analysis of the effects of world interest disturbances on the open economy term structure of interest rates abstract this paper studies the effects of world interest rate disturbances on the real domestic term structure of interest rates an intertemporal optimizing representative agent framework with variable employment and endogenous terms of trade is developed the economy faces an external borrowing constraint the adjustment of the short and long term rates as well as the discount bond yield curve is distinguished with the long rate and the yield curve derived recursively from the short both permanent and temporary world interest shocks are considered a notable result is that the yield curve exhibits relative maxima and minima for temporary disturbances

state owned mncs and host country expropriation risk the role of home state soft power and economic gunboat diplomacy expropriation risk has a binding effect on foreign direct investment fdi however state owned multinational corporations may counter the monopoly power of the host state by leveraging the political influence of their home government the magnitude of this counter force we argue may vary depending on the strength of political relations between the home and host state and the level of economic dependence of the host country on the home market we find supporting evidence of our hypotheses using chinese firm level fdi information between 2003 and 2010

dynamic analysis in the viner model of mercantilism abstract this paper models the central theme of mercantilism in jacob viner s interpretation power vs plenty in a framework of modern theory of international finance it is shown that in the viner model of mercantilism a nation with strong mercantilist sentiment ends up with large foreign asset accumulation and high consumption in the long run an import tariff leads to more foreign asset holding and more total consumption furthermore in the viner model the harberger laursen metzler effect exists unambiguously a permanent terms of trade deterioration causes a current account deficit in the short run

the effect of sanctions on u s foreign direct investment for years the united states has imposed economic sanctions to com pel countries to alter their behavior an important concern is whether government sanctions influence private foreign direct investment fdi decisions the largest source of foreign capital in the first study to assess empirically the relationship between economic sanctions and fdi we consider whether u s sanctions influence u s fdi inflows into targeted countries using panel data for 171 countries from 1965 to 2000 we find strong evidence that u s investors pull out of countries targeted for u s sanctions prior to their imposition this disinvestment is not permanent and invest ment tends to return after the sanctions are imposed the results provide support for fdi studies that show the effect of risk on investor decision making the use of economic sanctions by the united states to compel countries to alter their behavior has increased in recent years at the same time u s foreign direct investment fdi has expanded with u s multinational corporations mncs rep resenting the largest share of global fdi despite the growth of u s fdi and the u s government s imposition of sanctions no empirical work has considered the relationship between sanctions and u s investor decisions how do u s mncs react to the use of u s sanctions and does u s fdi make sanctions more or less effective in this article we analyze the impact of u s sanctions on investment decisions made by u s mncs building on investors risk calculations that are critical to the fdi literature 1 we propose several reasons why risk linked to economic sanctions influences fdi flows we hypothesize that u s firms significantly draw down their investment in tar geted countries prior to the imposition of sanctions as risk levels are most height ened however after sanctions have been in place long enough for investors to understand their specific restrictions uncertainty surrounding the amount of risk decreases and u s fdi is expected to return to levels near the pre sanction period

optimum borrowing and the current account when there are fluctuations in income abstract current account issues are examined in a context in which expenditure and borrowing are chosen optimally permanent falls in income are first discussed and the analysis deals with fixed and endogenous discount rates and interest rates a smoothing response in consumption producing a current account deficit is shown to follow a short term income fall however a long term fall can call forth an adjustment response with consumption and debt first moving toward the equilibrium which would obtain if the income fall were permanent

economic growth and defense spending granger causality abstract this paper uses granger causality to check the assumed exogeneity of military spending relative to economic growth in previous studies of the relationship between economic growth and military spending the test results performed using two measures of military spending consistently show that military spending is not a strongly exogenous variable implying that previous work in this area is flawed

optimal monetary growth with accommodating fiscal policy in a small open economy abstract this paper emphasizes how the choice of the optimal monetary growth rate in a small open economy under perfect capital mobility depends upon the accommodating policy chosen to maintain the overall budget constraint in the economy when this occurs through lump sum taxation the optimal monetary growth rate is shown to be the distorted friedman monetary rule if the adjustment occurs through the income tax rate the optimal monetary growth rate involves a phelps type tradeoff between the income tax rate and the inflation tax rate the framework is suited for analyzing optimal macroeconomic policy in general and the latter part of the paper considers an optimal monetary fiscal package

military expenditure spin off and economic development abstract this paper analyses the strategic causes and the economic spin off effects of military expenditure in less developed countries a formal optimising model is used to show that defence burden in ldcs may be analysed principally in terms of strategic factors such as security and threat and is determined relatively autonomous of economic factors given this autonomousness we scrutinise the widely held belief that defence expenditure has a substantial spin off in the form of technological progress r d skill creation effective demand all of which has positive developmental effects econometric evidence for india shows that such claims are exaggerated and economic spin off from defence to development is weak

defence spending and growth in greece 1974 90 some preliminary econometric results during the period 1974 90 greece has allocated an average of 6 4 of gdp to defence yearly the greek defence burden is currently the highest among european union and nato members at the same time the greek economy has exhibited the lowest rates of growth and it is plagued by persistent economic problems this paper using disaggregated military spending data investigates its economic effects during the period 1974 90 preliminary results reported here are inconclusive

current account effects of a temporary change in government expenditure a perfect foresight model of intertemporal utility maximization is used to analyze the current account effects of a temporary increase in government spending the relationship between the marginal utility of private consumption and the supply of public goods in the economy is shown to play a crucial role in determining the qualitative nature of the optimal current account response the link between the timing of the policy change and the magnitude of the current account effect is also examined
