A model of trust in quality and North–South trade

Why do some countries produce higher quality goods than other countries? This paper suggests that one reason is self-perpetuating reputations, modelling the idea with a Klein–Leffler reputation model embedded in a general equilibrium model of trade. Reputation differences are particularly interesting because reputation is a form of “social capital”. Like product differentiation, it can explain why countries might trade even if their technologies and endowments are identical, why firms could profit from exports even if the foreign price is no higher than the domestic one, and why governments like to have “high-value” sectors. Ideally, a developing country would shift its own producers to a high-quality equilibrium; if that is not possible, the next best thing is to import experience goods and substitute to home production of goods for which reputation is not important.     

A monetary model of China–US trade relations

This paper develops a general equilibrium monetary model to study China–US trade relations. The model captures two main features of China–US trade: China's fixed exchange rate regime and the use of the US dollar as the international medium of exchange. The main conclusions of this paper are threefold. First, an improvement in the productivity of China's tradable sector would benefit both China and the US. Second, a RMB appreciation would reduce consumption in the US and increase consumption in China, and would likely reduce China's trade surplus. It would also lead to a contraction in China's tradable sector and an expansion in US's tradable sector. Third, a monetary expansion in the US would hurt China because it would lead to a transfer of wealth from China to the US, a fall in China's relative wage rate and terms of trade, and an artificial expansion in China's tradable sector. A US monetary expansion would also increase China's trade surplus.     

Cap and trade to solve environmental problems ——an analysis of approach in the EU

Environmental problem is a global problem, which has been emphasized by many countries all over the world. To handle the climate change, international community has tried many means. This paper will focus on the approach called "cap and trade", and analyze its application in the EU—the EU Emissions Trading System (EU ETS). The effectiveness of the EU ETS in different phases will be analyzed in detail, as well as the benefits of the EU ETS comparing with other means of reducing greenhouse gas. It can be found that "cap and trade" is a successful mechanism to reduce the greenhouse gas s and other countries are supposed to learn from the experience of the EU ETS.     

The Heckscher–Ohlin model and the network structure of international trade

This paper estimates for 28 product groups a characteristic parameter that reflects the topological structure of its trading network. Using these estimates, it describes how the structure of international trade has evolved during the 1980–2000 period. Thereafter, it demonstrates the importance of networks in international trade by explicitly accounting for their scaling properties when testing the prediction of the “Heckscher–Ohlin” model that factor endowment differentials determine bilateral trade flows. The results suggest that factor endowment differentials increase bilateral trade in goods that are traded in “dispersed” networks. For goods traded in “concentrated” networks, factor endowment differentials are less important.     

A dynamic analysis of the Korea–Japan free trade area: simulations with the G‐cubed Asia–Pacific model

This paper explores the effects of the proposed free trade agreement between Japan and Korea. Our experiments are based on a new dynamic simulation model, called the Asia‐Pacific G‐cubed Model, which incorporates the rational expectations and intertemporal optimizing behaviour of agents. The simulations show that both Korea and Japan benefit from the bilateral FTA although other countries lose. The output gains from the FTA are estimated to be larger when trade liberalization is undertaken by a tariff reduction that is more gradually phased‐in than rapid.

Existence of equilibrium in the Helpman–Krugman model of international trade with imperfect competition

Helpman and Krugman (Market structure and foreign trade. Increasing returns, imperfect competition, and the international economy. MIT Press, Cambridge, 1985) provide a synthesis of the traditional factor proportions theory of international trade and the theory of international trade due to the exploitation of scale economies in imperfectly competitive markets. They derive illuminating results about trade patterns and gains from trade, among other things, leaving unanswered the question of existence of equilibrium, however. The central significance of their characterization of properties of free trade equilibria with inter-industry and intra-industry trade calls for an analysis of existence of equilibrium. This is the object of the present paper. We prove the existence of equilibrium for the integrated multi-sector multi-factor Helpman–Krugman economy without national borders. Well-known conditions ensure that the world economy under free trade reproduces this equilibrium and thus establishes existence of a free trade equilibrium. Since an equilibrium of the integrated economy is not necessarily unique, the same holds true for a free trade equilibrium.     

Predator–prey dynamics in general equilibrium and the role of trade

We examine the implications of trade in an economy with two interrelated natural resources, focusing on the case of a simple predator–prey relationship. We derive a three-sector general equilibrium model where production functions are linked via the ecological dynamics of the natural system. Under autarky, this economy exhibits a steady-state equilibrium that overexploits the prey stock, reducing the linked predator population and overall welfare in the absence of harvesting controls. When two economies engage in trade, differences in the dynamics of the two resource systems can become the basis for comparative advantage. In this case, the predator–prey relationship leads to a source of comparative advantage in harvesting prey for a country with a lower autarky steady-state proportion of predators to prey. This feature has not been noticed in the literature and leads to a counterintuitive implication: free trade can help conserve predator and prey stocks in the country with the higher autarkic steady-state proportion of predators to prey. To illustrate the relevance of our analytic findings, we present the stylized empirical example of the effect of Chinook salmon imports on killer whale populations.     

Microeconomic analysis on the growth of trade volume in China: 1978–2007

The gravity equation is usually employed by researchers in the field of international trade to explain the growth of a country’s imports and exports volume, especially the manufactured goods. But in China, variables in the model, such as exchange rate, tariff, transportation cost, and spatial distance etc., are not sufficient to explain the riddle of China’s growth in trade volume. In fact, this growth in China’s trade volume is owing to the disintegration of production in the process of economic globalization, to the multinational corporations’ (MNC) vertical outsourcing of their manufacturing processes and procedures, and to the timely readjustment of Chinese enterprises on their strategies of participating in the international intra-product specialization. In this paper we establish an equilibrium model of intra-product specialization dominated by MNCs, and do some empirical tests on the growth in trade volume in China by using the variables including technological conditions of trade, similarity of economies, policy conditions of trade, disintegration of production and level of per capita capital equipment. The empirical results support our basic judgments.     

A cross-industry analysis of intra-industry trade measurement thresholds: Canada and the United States, 1988–1999

The measurement of intra-industry trade allows for the separation of horizontal from vertical intra-industry trade using thresholds to categorize different types of trade. Using product-level data on Canada–United States international trade and corresponding cross-industry determinants, this study tests the sensitivity of these thresholds finding that previous studies may have incorrectly specified the measurement of intra-industry trade.     

A closed-form solution to the transitional dynamics of the Lucas–Uzawa model

This paper studies how the intertemporal allocation determines the transitional dynamics to a given steady state and the long-term growth of an economy. Our main contribution consists in determining the solutions path for all the variables of the model, under fairly general conditions on σ and β.     

A generalization of the Cairns–Krautkraemer model and the optimality of the mining rule

There exists a rule of thumb of mines, which decides how the cut-off grade (the lowest grade of extracted ore) should change in response to a change in the price of the metal. It requires that the cut-off grade should decrease (increase) when the present value price of metal increases (decreases). In this paper, the optimality of the rule will be examined by generalizing the Cairns–Krautkraemer model under the perfect foresight assumption.     

Input–output analysis of CO2 emissions embodied in trade and the driving forces: Processing and normal exports

In recent years, energy-related CO₂ emissions embodied in international trade and the driving forces have been widely studied by researchers using the environmental input–output framework. Most previous studies however, do not differentiate different input structures in manufacturing processing exports and normal exports. Using China as an example, this paper exemplifies how implications of results obtained using different export assumptions differ. The study posits that the utilization of traditional I–O model results in an overestimation of emissions embodied in processing exports and an underestimation in normal exports. The estimate of CO₂ emissions embodied in China's exports drops by 32% when the extended I–O model is used. The choice of export assumption has more impact on the decomposition results for processing exports. The study further highlights that for a country with an export structure similar to China, it is meaningful to look into the impact of export assumption in embodied emission studies.     

On the existence and uniqueness of solution to the Lucas–Uzawa model

In this paper we define the concept of admissible solution and then provide closed-form solutions for all variables of the model along the transitional dynamics path. We present numerical simulations and compare our results with those obtained through the methods developed by Boucekkine and Ruiz-Tamarit and, Barro and Sala-I-Martin.     

On the Mitra–Wan forestry model: A unified analysis

We present a substantive and far-reaching generalization of the principal results in the economics of forestry, as formalized by Mitra and Wan (1986). Rather than a polarized dichotomy of linear and strictly concave, differentiable benefit (felicity) functions, we develop the theory in the context of functions that are supported at the golden-rule consumption and are not necessarily concave. Through a non-interiority condition on the set of zeroes of a resulting “discrepancy function,” we show the equivalence of finitely-maximal, maximal, minimal value-loss and optimal programs, and thereby answer questions left open by Brock and Mitra. Our synthesizing criterion is new to the capital theory literature, and in the concave setting, proves to be necessary and sufficient for the asymptotic convergence of good programs.     

A contribution to the chronology of turning points in global economic activity (1980–2012)

We propose a novel chronology of global business cycles based on industrial production data for a sample of 85 countries at a monthly frequency from 1980 until 2012 and the Bry and Boschan (1971) algorithm. We assess the methodology with statistical tools of signal detection theory and against existing chronologies of country-specific turning points. Finally, we conclude by introducing and evaluating a logit model of the probability of a global downturn occurring up to 12 months ahead. This model uses the macro and financial indicators tracked by the Database of Global Economic Indicators (DGEI) of the Federal Reserve Bank of Dallas (see Grossman et al., 2014) to offer advanced warning of upcoming turning points of the global cycle.     

Cost-minimization analysis of fingolimod compared with natalizumab for the treatment of relapsing–remitting multiple sclerosis in Sweden

Abstract

Background:

Fingolimod and natalizumab have the same European Union licence for the treatment of relapsing multiple sclerosis, and are considered by the Committee for Medicinal Products for Human Use (CHMP) to have broadly similar efficacy.

Objective:

A cost-minimization analysis was performed to compare differences in treatment costs between fingolimod and natalizumab from a societal perspective in Sweden.

Methods:

This analysis included costs associated with initiating and following treatment (physician visits and monitoring), continuing therapy (drugs and administration), and lost patient productivity and leisure time. Unit costs (in Swedish krona [SEK]) were based on regional data (median prices for physician visits and monitoring sessions). Natalizumab infusion costs were obtained from the national cost-per-patient database. Drug costs for both therapies were 15,651 SEK/28 days.

Results:

After 3 years, fingolimod use was associated with savings of 124,823?SEK/patient compared with natalizumab (total cost/patient: 566,718 SEK vs 691,542 SEK). Cost savings with fingolimod were 40,402 SEK/patient after 1 year and 301,730 SEK/patient after 10 years. Treatment with natalizumab was 18% more expensive than fingolimod therapy after 1 year and 23% more expensive after 10 years.

Limitations:

Based on the CHMP assessment, it was assumed that fingolimod and natalizumab have similar efficacy. The analysis was conducted for Sweden, and caution is needed in extrapolating the results to other countries.

Conclusion:

Fingolimod is cost-saving compared with natalizumab for the treatment of relapsing–remitting multiple sclerosis in Sweden.     

Is attack the best form of defence? A competing risks analysis of acquisition activity in the UK

The primary purpose of this paper is to investigate whethercompanies can use acquisition as a strategy to reduce theirlikelihood of take-over. The determinants of making an acquisitionand being taken over are modelled for the first time withina competing risks framework using two large samples of UK manufacturingcompanies which together cover most of the post-World War IIperiod up to 1990. Our results indicate that, ceteris paribus,companies which make acquisitions can significantly reduce theirconditional probability of being taken over by around one-third,largely through the impact that acquisition has on corporatesize. In this sense, attack, through acquisition, is the bestform of defence against take-over.     

Does trade liberalization and its associated increased economic activity affect permanently the value and pattern of trade flows?

Despite a number of multi-country case studies based on a variety of analytical frameworks and numerous econometric studies using large cross-country data sets that analyse trade openness and its induced economic activities that alters both the volume and value of trade flows, there is still disagreement among economists concerning the nature of this relationship. In this article, we follow a rather unique approach by estimating the density functions of the observed trade flows and the density functions of trade flows generated by tariff removal using an intertemporal global Computable General Equilibrium (CGE) model. Our inquiry is whether or not the trade flows generated by global tariff elimination impact economies in the long-run and alter their historical underlying distributions. If the latter case prevails, it implies that the economies follow a different transitional path into a new steady-state equilibrium. The density functions, estimated parameters and higher moments of the observed trade flow distributions are distinctly different from the parameter estimates of the trade flows generated by the model. In this sense, trade-inducing economic activity as generated by tariff removal and captured by the neoclassical specification of the model is associated with trade flows along a different transitional path from the observed trade flows.     

The US–China Phase One trade deal: An economic analysis of the managed trade agreement

In light of the recent tit-for-tat trade dispute between China and the US, interest in quantifying the effects of the so-called Phase One agreement has risen. To this end, this paper quantifies the impact of the asymmetric managed trade agreement using such a multi-country open-economy dynamic general equilibrium model. Besides assessing the direct implications for China and the US, this paper analyzes trade diversion effects. The model-based analysis finds noticeable positive (negative) impacts of the agreement for the US (China) as well as negative spillover effects for countries not directly affected by the managed trade deal due to trade diversion. The impact of possible future trade agreements is also examined.     

A characterization of the coskewness–cokurtosis pricing model

The coskewness–cokurtosis pricing model is equivalent to absence of any positive-alpha return for which the residual risk has positive coskewness and negative cokurtosis with the market. This parallels the CAPM and also the fundamental theorem of asset pricing.
