euro depreciation and trade asymmetries between germany and italy versus the us industry level estimates abstractsince april 2014 to march 2015 the european central bank expansionary monetary policy instigates a huge depreciation of the euro in terms of dollar according to the mainstream monetary theory these dynamics should make the exports cheaper and at the same time make the imports more expensive has real depreciation of the euro helped in the improvement of european countries trade balances following the main methodologies in the recent literature our study analyses the effects of this depreciation both for italy and germany towards the us we use industry level data at monthly frequency the results are different from each bilateral relationship we find that 11 industries register a long run improvement 8 for italy and 3 for germany the j curve effect is proven just in six cases always for italy the inverted j curve effect is proven in eight cases four for germany and four for italy these results seem to be an indirect demonstration of the structural asymmetries between german and ital

the j curve effect and the u s agricultural trade balance according to the j curve theory following a currency depreciation there will be an initial deterioration of the trade balance before an improvement is realized this paper finds empirical evidence indicating the first segment of the j curve does exist for the u s agricultural trade balance a 10 depreciation of the u s dollar is estimated to lead a deterioration of the agricultural trade balance that will last for about nine months

endogenous export prices and the taiwan us trade imbalance to explain the perplexing issue of why taiwan s trade imbalance with the us has persisted despite the depreciation of the dollar we estimate a four equation model to determine the direct pass through dpt and indirect cost adjustment ica effects of exchange rate changes on taiwan s export prices the ica effect is important in the case of taiwan because it imports mostly intermediate goods for the production of manufactured goods that are exported our findings support the view that dpt and ica effects reduce the effectiveness of exchange rate as a mechanism for international trade adjustment

taiwan s trade imbalance and exchange rate revisited this article applies the recently developed econometric method of autoregressive distributed lag ardl model to re examine the relationship between the exchange rate and bilateral trade imbalance for taiwan and its several trading partners china hong kong the us japan south korea and malaysia the implication of this issue is critical to policy makers particularly after china and taiwan joined the world trade organization wto in late 2001 and early 2002 respectively the empirical evidence shows a stable long run relationship of bilateral trade balance and real exchange rate between taiwan and its trading partners except japan other findings indicate that except for the us there is no specific pattern supporting the j curve phenomenon for these trading partners

determinants of international trade flows this paper models and estimates import demand and demand for export functions for 19 industrial countries although primary emphasis is placed on the period of generalized floating exchange rates 1972 through 1980 estimates are also provided for the fixed exchange rate years 1957 1970 thus making possible a comparison between the two eras aside from the conventional income and price variables the paper assesses the effect of variations in the exchange rate and in the expected exchange rate on real trade flows additionally it estimates an unrestricted lag structure of the effect of price and exchange rate variations on imports

bilateral j curve between india and her trading partners india a land of over one billion people and one of the newly emerging industrial powers in the world is going through a slow but steady metamorphism for centuries india has played a major role in the international trade it was not uncommon to see her ships carrying silk and spices across the arabian seas and bringing back machine made textile invasions of india first by mughals and latter by the british through the east india company were all trade oriented india s presence in the world trade is relatively small at this time but is gaining momentum after independence in 1947 india for a brief period experimented with socialism the five year plans were mainly focused towards building infrastructure and development of small scale agriculture based industries the industrial development even though extremely important for growth played a secondary role the foreign investment was encouraged but only in the selected sectors of the economy however threat of nationalization a large bureaucracy corruption lack of understanding of the indian business practices and the requirement that a major share holder must be an indian national discouraged foreign capital investment in india during 1991 1992 india adopted a policy of trade liberalization to attract foreign capital and to encourage non resident indians to invest in their home country government of india established a separate unit within the home ministry whose main function was to expedite processing of applications india also relaxed the requirement that a major partner be an indian national india provided export subsidies to the exporters in terms of cash as well as foreign exchange so that they could import machines and raw materials exports responded to the trade liberalization and increased from 44 041 crores of rupees in 1991 1992 to 141 603 crores in 1998 1999 where one crore is equivalent to ten million in us dollar terms at a current exchange rate of 42 48 rupees per dollar this translates to an increase from 10 37 billion to 33 34 billion over eight years india also anticipates that through a major increase in the information technology mainly software industry her exports will increase to 90 billion by 2005 the trade liberalization has been accompanied by changes in the monetary policies the inflation rate has been reduced from about 12 to 9 per year the interest rates have declined from 14 to 10 and the exchange rate has been allowed to respond to market forces as a result from 1991 1992 to 1998 1999 the rupee has declined from 19 62 rupees per dollar to 42 48 rupees per dollar by december 2000 rupee had further devalued to 46 25 per dollar with a hope that it will further boost india s exports and improve her trade balance however the impact of currency depreciation on the trade balance is not instantaneous indeed there is ample evidence in the literature that after currency depreciation the trade balance worsens in the short run before improving in the long run since this pattern of movement of the trade balance over time resembles the letter j magee 1973 labelled it the j curve phenomenon magee argued that after devaluation contracts that are in transit at old exchange rates dominate the short run response of the trade balance over time new contracts at new prices begin to exert their favourable impact at this stage elasticities may increase leading to an eventual improvement in the trade balance of course the delayed response could also be due to lags in the process of increasing the production of exportables junz and rhomberg 1973 have identified five lags namely recognition lags decision lags delivery lags replacement lags and production lags only after the realization of these lags the trade balance could improve early studies that tried to investigate the impact of currency depreciation on the trade balance relied upon estimating the marshall lerner condition the condition

predicting the competitive relationships of industrial production between taiwan and china using lotka volterra model abstractthis work is the first to apply lotka volterra model combined with genetic algorithm ga to predict the production relationships of high tech industry among different areas previous studies analysed the trade interdependency among various countries but few studies have highlighted the quantitative evidence of production relationships thus this study utilizes motherboard shipment volumes to predict the competitive relationships of industrial production on both sides of the taiwan strait specifically this work uses simultaneous non linear least square regression in combination with gas for numerical parameter optimization of the proposed lotka volterra model the results of parameter estimation reveal that shipment growth in china substantially promotes that in taiwan whereas the shipment growth in taiwan curtails that in china the standard deviation of the estimated parameters from the 3000 iterated simulations is small confirming the reliability and stability of our parameter estimations

optimal non linear pricing with regulatory preference over customer type abstract in this paper we characterize the pareto optimal set of non linear pricing schedules when non negative weights are assigned to each customer type our analysis first compares general non linear tariff schedules and sets of self selecting two part tariffs when there are two customer types and the cost function is linear we then derive optimal sets of two part tariffs for arbitrary numbers of customer types and general cost functions we also consider the sustainability of non linear pricing schedules under the threat of entry of rival firms

small farmer cooperatives and voluntary coffee certifications rewarding progressive farmers of engendering widespread change in costa rica abstract our research examines the benefits and drawbacks for cooperatives who participate in voluntary coffee certifications we interviewed administrators at twenty costa rican coffee cooperatives about management practices related to voluntary certification voluntary certifications are popular among coffee cooperatives access to certified markets is facilitated by state support of the cooperative sector regulation of the coffee sector and well enforced environmental and social laws however there are no significant or consistent financial incentives for farmers to pursue certification multiple certifications may lower auditing and implementation costs but cooperatives rarely receive the full premium for multiply certified coffee low market demand for certified coffee weak price incentives and high auditing and management costs encourage cooperatives to certify only a portion of their members this strategy rewards compliant farmers rather than inducing widespread change to farming practices among the entire membership though financial incentives are weak certifications offer non financial benefits to both farmers and cooperatives including better management and more resilient cooperatives

effects of exchange rate variations on bilateral trade with a vehicle currency evidence from china and singapore abstract using a testable gravity type bilateral trade model derived from an underlying demand and supply model this paper explores the effects of exchange rate variations on bilateral trade in an exchange rate regime with a vehicle currency the introduction of the vehicle currency allows us to figure out whether variations in the trade volume due to the fluctuation of the bilateral exchange rate are primarily due to changes in demand or in supply or both more specifically in this theoretical framework the appreciation of one country s currency against the vehicle currency is expected to promote its imports but the effect of revaluation of the country s currency against the vehicle currency on its exports is ambiguous moreover high volatility of the exchange rate of one country s currency against the vehicle currency is also expected to depress its import volume from the empirical point of view the decomposition of the bilateral exchange rate of two currencies into the bilateral rates of these two currencies against the vehicle currency provides a new alternative to avoid the econometric problem of potential reverse causality in assessing the effects through compiling a novel monthly bilateral trade dataset between china and singapore over 21 years or 252 months we empirically test the predictions of our model which get robust support from the results

the j curve a literature review due to lag structure currency devaluation is said to worsen the trade balance first and improve it later resulting in a pattern that resemble the letter j hence the j curve phenomenon since its introduction by magee in 1973 brooking papers on economic activity 1 pp 303 25 a large number of studies have attempted to test the phenomenon using different techniques and different model specifications the results are at best ambiguous and deserve to be collected together for the future generation of researchers and graduate students this paper fills such a vacuum in the literature by reviewing the j curve related empirical papers

is there a j curve abstract if the response of the value of the trade balance to movements in the real exchange rate is described by a j curve then a real depreciation initially worsens a balance of trade deficit only improving it over time this paper investigates whether a j curve can be detected in the last twenty five years of american data no statistically reliable evidence of a stable j curve is detected the model is checked extensively to support this finding

the latte revolution regulation markets and consumption in the global coffee chain abstract coffee is a truly global commodity and a major foreign exchange earner in many developing countries the global coffee chain has changed dramatically as a result of deregulation new consumption patterns and evolving corporate strategies from a balanced contest between producing and consuming countries within the politics of international coffee agreements power relations shifted to the advantage of transnational corporations a relatively stable institutional environment where proportions of generated income were fairly distributed between producing and consuming countries turned into one that is more informal unstable and unequal through the lenses of global commodity chain analysis this paper examines how these transformations affect developing countries and what policy instruments are available to address the emerging imbalances

fair trade organic coffee production in nicaragua sustainable development or a poverty trap abstract this article assesses the impact of fair trade organic coffee production on the well being of small scale farmers in nicaragua studying the results of organic management is crucial for evaluating the advantages of fair trade because approximately half of all fair trade coffee is also organically certified a wide range of farmers representatives of cooperatives and export companies in nicaragua were interviewed during seven months of field work between 2005 and 2008 fair trade organic production raises farmer income when low intensity organic farming is an alternative to low intensity conventional farming however low intensity farming produces very little coffee in the case of the most marginalized farmers keeping these farmers in poverty with higher intensities of management the economic advantages of fair trade organic production largely depend on prices in the mainstream market

was it real the exchange rate interest differential relation over the modern floating rate period in this paper we explore the relationship between real exchange rates and real interest rate differentials in the united states germany japan and the united kingdom contrary to theories based on the joint hypothesis that domestic prices are sticky and monetary disturbances are predominant we find little evidence of a stable relationship between real interest rates and real exchange rates we consider both in sample and out of sample tests one hypothesis that is consistent with our findings is that real disturbances such as productivity shocks may be a major source of exchange rate volatility this paper investigates the empirical relationship between major currency real exchange rates and real interest rates over the modern post march 1973 flexible rate experience the exchange rates examined here include the dollar mark dollar yen and dollar pound rates our two major findings are as follows first the data do not indicate a strong correspondence between real interest rate differentials short term or long term and real exchange rates this finding appears to conflict with the predictions of most monetary and portfolio balance models of exchange rate determination though the conflict can be substantially reconciled if aggregate disturbances are primarily real in nature i e changes in productivity tastes etc it is true that in many cases the sign of the estimated exchange rate interest rate differential relationship is consistent with the possible predominance of financial market disturbances but the relationship is not stable enough to be statistically significant second although one does find some evidence of a unit root in both real exchange rates and long term but not shortterm real interest differentials these two series do not appear to be linearly cointegrated hence the nonstationarity or near nonstationarity in the two series cannot be attributed to the same factor in section i we briefly describe a class of small scale monetary models of exchange rate determination the importance of this class of models for empirical work derives from its strong predictions about how the exchange rate will move

transitory and permanent disturbances and the current account an empirical analysis in the intertemporal framework the intertemporal models of current account determination demonstrate that in the analysis of the current account balance of a country it is important to distinguish between transitory and permanent disturbances in income and relative prices this paper attempts to decompose the observed data on income and real exchange rate into transitory and permanent components and then uses the decomposed series to test the empirical validity of the predictions of the intertemporal models evidence from the united states and japan provide very limited support for the intertemporal models in terms of the effects of transitory and permanent changes in income on current account balance for both us and japan the study finds that permanent changes in real exchange rate have significant effects on the current account balance statistical tests find no evidence of hysteresis in the trading relations of the two countries

the j curve effect and us agricultural and industrial trade this paper examines the j curve hypothesis for us agricultural and manufactured goods using the shiller lag model the results support the j curve effect for agricultural goods but not for manufactured goods these findings explain why many studies in the literature fail to support the j curve phenomenon there are two explanations for these findings 1 the aggregation bias of data that combine both agricultural and manufactured goods and 2 the country under study is often an industrial nation like the us or japan with a high proportion of manufactured goods in both exports and imports

measuring global money market interrelationships an investigation of five major world currencies abstract this paper extends the study of global money market integration in two primary directions first a technique which combines stationarity and cointegration tests as a basis for constructing an error correction model is applied to assess the existence of long run equilibrium relationships between money market series second analysis for the increasingly significant asian offshore markets of singapore and hong kong is added to traditional european and national markets analysis major findings are 1 the error correction model is an appropriate technique for identifying causality relationships and 2 major domestic markets and included offshore markets are partially segmented

the effects of fair trade on coffee growers a framework and analysis the world coffee market has undergone a significant transformation in the past couple of decades resulting in declining farm prices despite the fact that coffee demand has been strong and consumer prices have been soaring fair trade organizations have tried to address this price imbalance by providing an alternative method of trading aimed at increasing the prices received by coffee growers despite their noble objectives fair trade movements have had limited success in improving coffee growers welfare however this paper utilizes a novel framework of heterogeneous producers and relevant market information to provide insights on the market and welfare impacts of the fair trade regime when important idiosyncrasies of fair trade production and marketing are included in the analysis

cointegration how short is the long run abstract when testing for cointegration and faced with short sample periods it is common for researchers to turn to more frequently sampled observations that is to move from annual to quarterly or monthly data in order to increase the number of observations we argue that such a gain in the degrees of freedom is more apparent than real essentially cointegration is a long run concept and hence requires long spans of data to give tests for cointegration much power rather than merely large numbers of observations using monte carlo simulations we demonstrate this for four popular tests for cointegration

nonlinear pricing and price cap regulation abstract this paper analyzes profit maximizing nonlinear pricing by a firm that is subject to price cap regulation two forms of regulatory constraint are considered i a cap on the firm s average revenue and ii a constraint that the firm must continue to offer each consumer the option of buying at the uniform price optimal nonlinear price schedules in these regimes are shown to have simple characterizations that are related to the nonlinear tariffs that an unregulated monopolist would charge of the regulatory regimes the firm prefers the average revenue constraint to the option constraint and likes uniform pricing least consumers in aggregate prefer the option regime to uniform pricing and like the average revenue constraint least but there are also distributional effects between consumers although the optional tariff regime pareto dominates uniform pricing it is ambiguous whether welfare is higher under uniform pricing or under the average revenue regime an example is used to illustrate the nature of the ambiguity

exchange rates and fiscal policy in a popular model of international trade this paper develops a reinterpretation of the devaluation analysis in a popular model of international trade developed by charles bickerdike joan robinson and lloyd metzler it has come to be known as the elasticity approach 1 that model developed in terms of independent markets for imports and exports has been criticized for its apparent lack of general equilibrium properties the assumptions underlying the model have remained by and large implicit and vary across users and the integration of this analysis with the absorption approach and macroeconomics has never been demonstrated all this is very much recognized and indeed application of the model is consistently accompanied by appropriate partial equilibrium impact effect or upper bound caveats these shortcomings notwithstanding the model continues to enjoy substantial popularity in policy discussions and interpretations of current events in empirical work and in recent textbooks in the field of international economics the brm model is likely to remain the preferred tool in the analysis of trade balance issues along with the foreign trade multiplier model it is therefore interesting and useful to enquire into its formal general equilibrium implications this paper is concerned with one such interpretation involving a nontraded goods sector and a well defined government policy that makes the analysis consistent with the absorption approach while it may well be possible to generate alternative interpretations the present analysis would seem to have the advantage of simplicity while at the same time pointing out the essential properties that would have to be satisfied by alternative treatments in section i a brief review of the brm approach is offered in section ii that approach is interpreted in terms of a simple model with nontraded goods and constant terms of trade the implicit assumptions of the brm model are brought to the f oreground by an explicit consideration of the market for home goods the equilibrium conditions and the role of the relative price of nontraded goods 3 following that analysis section iii considers the subsidiary issues that are raised by variable terms of trade the notion of total elasticities is given an interpretation in section iv where we return to the composite traded good model to explore alternative assumptions about absorption policies

taiwan s exports and trade imbalance against us and japan an empirical analysis the persistence of the bilateral trade surplus between taiwan and the usa and the bilateral trade deficit between taiwan and japan despite the significant appreciation or depreciation of the nt dollar during the early 1980s to the mid 1990s renewed interest to seek explanations for these phenomena to assess the above proposition a polynomial distributed lag pdl method is imposed on the impact of changes in the real exchange rate on the bilateral trade structure particularly export demand and trade imbalance between taiwan the usa and japan from 1981 to 1998 the empirical findings show that 1 the real income factors have important effects on the real exports in both cases 2 the real exchange rates and the real imports are not major determinants of the export demand from taiwan to the usa but they do play an important role on the real exports from taiwan to japan 3 the real exchange rate has significant effect on the real trade surplus with the usa and on trade deficit with japan but the real

rate of return regulation and product variety abstract this paper examines the effect of rate of regulation on a monopolist that faces a market of observationally identical but heterogeneous consumers under plausible technological conditions rate of return regulation increases the quality offered to any consumer and expands the variety of products it offers some consumers receive a quality that is greater than the socially optimal quality rate of return regulation unambiguously increases consumers surplus if the allowed rate of return is close to the monopoly rate of return social welfare increases as well

taiwan s exports and trade imbalance against us and japan an empirical investigation based on error correction model this study employs recent advances in time series analysis cointegration and error correction model to examine the long run and short run determinants of the exports and trade imbalance between the usa japan and taiwan the unit root tests reveal nonstationary in most of the variables the cointegration tests affirm positive the long run associations are between the exchange rate changes and the exports as well as the trade imbalance once these long run effects are accounted for it is found that there are evidences of short run relationship between these variables

vertical product differentiation and the import demand function theory and evidence in this paper we use a model of vertical product differentiation to cast doubt on the general validity of the import demand function as specified in macroeconomic models the empirical importance of our theoretical concerns is then established according to our first hypothesis the share of a good s imports in total imports is non increasing in domestic wages if the country has comparative advantage in high quality varieties of this good the second hypothesis states that the share of a good s imports is increasing in non wage domes tic income if the country has comparative advantage in high quality varieties of this good

the balance of trade and exchange rates theory and contemporary evidence from tourism abstract the purpose of this study is to investigate the effects of exchange rate depreciations and appreciations on the tourism trade balance specifically we employed linear and nonlinear autoregressive distributed lag ardl cointegration techniques to analyze the extent to which currency depreciations and appreciations affect the united states u s bilateral tourism trade with canada mexico and the united kingdom u k the results showed that the depreciation of the u s dollar subsequently improves the u s trade balance with all three trading partners however while the appreciation of the u s dollar deteriorates the u s bilateral tourism trade balance with canada and the u k it does not ultimately affect the u s bilateral tourism trade with mexico in the long term these results provide evidence contradicting the j curve theory supporting the postulations of the ml condition theoretical and policy implications are discussed within the realms of j curve theory marshall lerner ml condition international trade and tourism

nonlinear prices and the regulated firm this paper examines the problem of a regulated utility that sells output according to a nonlinear price schedule three results are obtained first rate of return regulation lowers the price schedule charged by the firm along its entire length second some units of output will always be sold at a marginal price below true marginal cost third a move from linear to nonlinear prices at a given fair rate of return can lead to an unambiguous increase in welfare

welfare effects of price discrimination by a regulated monopolist should a multiproduct monopolist whose average price is capped by regulation be allowed to engage in third degree price discrimination if the cap applies to a price index with weights proportional to demands at uniform prices then price discrimination benefits consumers as well as the firm but if perhaps more realistically it is the firm s average revenue that is capped then consumers prefer uniform pricing in this case total output is higher when discrimination is allowed which increases welfare but marginal utilities differ across markets which is inefficient and the overall effect is ambiguous a small amount of discrimination is desirable however it is better not to allow price discrimination if the price cap is close to the level of marginal cost the consequences of tightening the price cap when discrimination is allowed are also examined

exchange rate policy and trade balance a cointegration analysis of the argentine experience since 1962 using multivariate cointegration tests for nonstationary data and vector error correction models this article examines the determinants of trade balance tb for argentina over the last forty to fifty years taking into account that the short run impacts of currency depreciation on the tb behaviour may differ from the long run effects our investigation confirms the existence of long run relationships among tb real exchange rate rer and foreign and domestic incomes for argentina during different rer management policies based on the estimations the marshall lerner condition is checked and by means of impulse response functions we trace the effect of a one time shock to the rer on the tb not finding support for a j curve pattern in the short run
