Labour migration in a model of North-South trade

A dynamic general eqilibrium model of the world economy is adopted to examine the benefits and drawbacks of labour migration to each of the participatingregions. It is demonstrated that, especially in the long term, the migration of workers may be mutually beneficial: the region of immigration making production gains, while that of emigration perceives a higher demand for its products. In contrast to previous results, it is shown that no immigration limits would be imposed even if migrants' incomes were taxed and, indeed, differentiated payments to immigrants is suboptimal     

Foreign trade and innovation in domestic labor relations

For the most part, neoclassical trade theory has restricted its concerns to the effect that trade has on the production and distribution of commodities. It implicitly assumes that international trade leaves unchanged the institutional structure of domestic economies.The empirical evidence presented here supports the claim that international trade induces innovation in the institutions regulating the capital-labor relationship. Existing trade theories, neoclassical or otherwise, that assume away such changes give only a partial answer to one of the central questions a theory of trade must answer: What are the effects of trade, and are these effects beneficial?     

A competitive general equilibrium model of technology transfer,innovation, and obsolescence

A general equilibrium production model is developed where technologies are embodied in capital goods of different vintages indexed in a continuum. A difference in the extent of existing knowledge determines a wage gap between a developed (north) and a developing region (south). With free flow of technology, relatively backward technologies move to the south. With innovation in the north, a technology cycle is created by which some of the technologies are pushed out of the north into the south. This also tends to widen the wage gap between the regions.     

A model of technology strategy

Technology strategy, a relatively new concept in management theory, describes how firms might use technology to gain competitive advantage. However, little practical information exists to assist firms in incorporating technological issues into the overall strategy of the firm. To counter this, a utilitarian, time-based model of the process of technology strategy has been developed. The proposed model links six technologially related tasks with decreasing time-frames, which are based on Jagues organizational constructs. Such time-frames reflect short-, medium-nad long-term future periods relevant to management decision-making and corporate development activites. The spectrum of tasks and time-frames are in the following ranges; setting horizons, beyond 20 years; industry forecasting, relating to the peirod 10-20 years ahead; technology positioning, 5-10 years; determining technology availability, 2-5 years; appropriating technology, between 1-2 years; managing technology, relating to the first year.In outlining these tasks and time-frames, it is argues that the six tasks are interrelated and should operate in parallel, in an iterative manner.     

Capital Flight, North-South Lending, and Stages of Economic Development

We present a two-country OLG economy in which international capital mobility exists in the presence of moral hazard in financial contracts. The difference in the extent of asymmetric information is a source of capital movement and capital flows from the South to the North. Even though there exists a unique steady state under autarky, multiple locally stable steady states may emerge in a world economy with an integrated capital market. However, the integration may drive the South down to further impoverishment. The South's government therefore should take into account seriously the timing of capital market liberalization as a conduit of economic development.     

North-South and South-South trade-related technology diffusion: an industry-level analysis of direct and indirect effects

Abstract .  This paper examines one direct and three indirect channels of North-South trade-related technology diffusion. We find that i) the largest impact on TFP in the South is from direct North-South technology diffusion; ii) there are also significant effects from indirect North-South technology diffusion, though their magnitude is smaller than that of the direct one; and iii) the impact of direct North-South technology diffusion on TFP in the South occurs faster than the impact of indirect technology diffusion.     

A model of technology adoption and growth

Summary We construct a model of economic growth in which firms adopt more advanced technologies. In order to advance its technology, a firm must make an investment. The size of this investment depends on the size of the technology adoption barriers in the firm's country Assuming a Markov chain for these barriers, we examine the amount of variation and persistence in the chain for which the model matches the observed output disparity across countries and the mobility of nations. Our calibration suggests a range for the size of these barriers of a factor five, and the presence of a barrier trap.The author is grateful to V. V.

Economies of Scale, International Capital Mobility, and North-South Inequality

This paper develops a model of North-South trade with a continuum of goods, external economies of scale and international capital mobility. The North-South wage gap must exceed any difference in labor quality for South to overcome the established external economies in North. In equilibrium North retains the goods with the largest external economies and South specializes in the remaining goods. While Northern product innovation leads to the production of additional goods in South, it is possible for South to experience a terms-of-trade deterioration, a reduction in foreign investment, and an increase in wage and income inequality.

Imported technologies,urban unemployment and the North-South dialogue

This paper extends the Harris-Todaro model with intersectoral capital mobility to include sector specific imported technologies. Technologies are assumed to be embodied in imported capital goods. The small economy in the South, for which the model is defined, can import any amount of these technologies from the North at given royalty rates. We find that if the North agrees to reduce the royalty rate on the industrial technology, both the level and the rate of urban unemployment would rise and the income distribution change against the wage earners, whereas such a reduction for the agricultural technology would have just the opposite effects. A decrease in either royalty rate would increase the national income in the South, although the magnitude of the increase in income would be larger with reduced royalty rate for agricultural rather than industrial technology. The policy implication is that the South should emphasize the import of agricultural technology over the industrial technology.     

Trade-Related Intellectual Property Rights, North-South Trade, and Biological Diversity

In the Trade-Related Intellectual Property Rights (TRIPS) Agreement of GATT (1 January 1995) it was agreed to harmonise intellectual property rights (IPR) on an international level and to include the option for patent protection for all life forms such as plants and animals (Article 27 (3) b). Patenting, however, leads to considerable conflicts between international trade and protection of biological diversity, which can be illustrated by the example of seed production. We make use of a three-stage game to show the strategic incentives for implementation of two different property rights regimes (patents and farmers' rights) on competition and biodiversity. We show that the Southern government has no incentive to acknowledge international patents, even if farmers' rights do exist. The Northern producer will always dominate in the output market if patents are applied, but without farmers' rights biodiversity will not be maintained by the Southern government. Thus total payoff of the northern firm is maximized, if both IPR regimes are implemented. However, if only farmers' rights are valid, biodiversity will be maximal.     

A general model for culture and technology

This paper offers a process model in which the interaction of technology and social institutions can be analyzed systematically within a single frame of reference. By considering both aspects of culture, not as substantive entities to be classified as to type, but as organizational states to be described and measured by a class of variables that is truly scaleable, it is possible to describe with precision and economy, a given state of techno-social organization and also design and predict future states of technological and social organization The potentialities and properties of various possible future states can be projected as highly compressed, synoptic models since the number of variables used to describe a real or projected system-state is small. Thus the model offers a versatile instrument for disciplining rich and diverse classes of data into manageable wholes. It also offers possibilities of making normative judgements of what kind of organizational linkages between technology and social institutions will produce relative consistency or effectiveness.     

International Transmission of Government Spending,Monopolistic Competition and North-South Trade

This paper utilises a North–South general equilibrium model where South exports an intermediate good to North in exchange for differentiated goods. The model is used to examine international transmission of government spending and its welfare implications. It is shown that an increase in government spending in North (South) can increase (decrease) the number of differentiated goods produced, thereby decreasing (increasing) the degree of monopoly power in North. Furthermore an increase in government spending in South can decrease the welfare North, but the impact of an increase in government spending in North the welfare of South cannot be unambiguously determined.

The distribution of demand, market structure, and investment in technology

In a quality-ladder growth model, the dispersion in the demand for quality influences the prices innovators may charge for their innovations and the number of such firms that may obtain market shares at any one time. Under a more dispersed distribution, the innovator may only charge a lower price to cover the entire market. The payoff to innovation declines, causing investment to fall. When the dispersion has reached a critical level, the innovator will no longer price out the incumbents, turning the market into a natural oligopoly with firms selling different grades co-existing at any one time, even if it is optimal for all consumers to buy the highest grade available. Any further increases in dispersion raise the payoff to innovation, inducing greater investment.     

A stochastic model for technology forecasting

A hybrid selection model for emerging technology

Technology selection, which influences the advantages of an enterprise or a country, is a multi-criteria decision issue that can be improved by integrating different methods. In addition, it is more and more difficult to identify the right technologies because the technologies are increasing in number and complexity. This study proposes a technology selection process integrating fuzzy Delphi method, analytic hierarchy process (AHP), and patent co-citation approach (PCA) for technology selection. The former effectively gathers experts' judgments toward technology selection criteria and conducts the fuzziness existing in their responses. The analytic hierarchy process has the strength of identifying criteria and obtaining their relationship and their weights. The patent co-citation approach identifies the major R&D fields of a specific technology from patent data. Through this proposed process, the key technology fields can be identified in the end. The organic light emitting diode (OLED) technology in Taiwan is used to be an example to illustrate the proposed technology selection process.     

Finance constraints and technology spillovers from foreign to domestic firms

Scholars have suggested that externalities such as technology spillovers to domestic firms from the entry and presence of foreign firms – i.e., Foreign Direct Investment (FDI) spillovers – arise only when domestic firms possess adequate absorptive capacity. But they have also maintained a predominantly technological focus in their conceptualization of absorptive capacity, treating it mostly as a function of domestic firms' technological investments. Yet, several anecdotes point to finance constraints being equally important hurdles to absorbing technology. Given the comparatively scant attention to finance constraints in the FDI spillover literature, we present theoretical arguments and a counterfactual simulation for how finance constraints influence firms' realization of FDI spillovers. In the process, we identify two mechanisms underlying why firms facing high finance constraints experience lower FDI spillovers. (125 words).
