The complementary nature of technological capabilities: Measurement and robustness issues

The application of composite indicators to complex phenomena in social science has come to remarkable prominence. As a result, they have been widely applied in wide-ranging fields. This paper explores the application of a composite indicator of technological capabilities that can be also valid for composite indicators in other fields. We focus on whether different methodologies to build composite indicators lead to different results. The arithmetic mean to aggregate technological capabilities variables has been widely criticized, as it allows for perfect substitutability between variables, thus disregarding the complementary nature of technological capabilities. We introduce a new aggregation rule, the concave mean, in order to take into account the complementarity argument in a Science-Technology-Innovation context. Using a dataset for 138 countries, we show that the arithmetic mean is biased in principle but robust in practice. This depends upon the fact that technologically more advanced countries tend to have a more complementary structure in their technological capabilities compared to less developed nations.     

IS CORPORATISM FEASIBLE?

This paper investigates the effects of cooperation (corporatism) on macroeconomic performance by considering a rather standard policy game between the government and a monopoly union. We stress the shortcomings of the traditional way used to model cooperation in policy games (the maximization of the weighted sum of players’ preferences), which only approximates the Nash product solution. We find that it is difficult to implement corporatism, although it generally increases social welfare, as it often reduces the union's utility. In particular, we show that an inflation‐neutral union will never find it profitable to cooperate with the government, unless side‐payments are considered. The study of this issue, however, is beyond the scope of this paper.     

Welfare Implications of a Preferential Tariff Reduction for Agricultural Exports from Less Developed Countries vs. a Generalized Tariff Reduction

The paper presents the results of a theoretical study focusing on a comparative evaluation of the welfare effects of a preferential tariff reduction for agricultural exports from less developed countries versus a generalized tariff reduction. The results are derived using a diagrammatic approach. The analysis is developed within a partial equilibrium framework with one commodity, three large countries (importing developed country, exporting developed country, developing country), fixed exchange rates and zero transportation costs. The theoretical model makes provisions for a country to switch from being an exporter to being an importer, or vice versa, as the equilibrium price changes. Three alternative policy scenarios are analyzed: the imposition of a non-discriminatory tariff, a preferential tariff reduction, and a generalized tariff reduction. Two alternative definitions of the welfare functions are used. One is based on consumers' and producers' surplus, the other adds domestic income and changes in foreign exchange earnings/expenditure. Some methodological implications of the specific model used are discussed, along with the impact, in terms of welfare, of the policy scenarios considered.     

How limiting deceptive practices harms consumers

There are two competing sellers of an experience good, one offers high quality, one low. The low‐quality seller can engage in deceptive advertising, potentially fooling a buyer into thinking the product is better than it is. Although deceptive advertising might seem to harm the buyer, we show that he could be better off when the low‐quality seller can engage in deceptive advertising than not. We characterize the optimal deterrence rule that a regulatory agency seeking to punish deceptive practices should adopt. We show that greater protection against deceptive practices does not necessarily improve the buyer welfare.     

Taking Actively Advantage of MNCs’ Presence

In this paper, not only do we posit that the presence of a multinational corporation may entail significant benefits for the host economy and local firms’ performance, but also that these benefits can be actively sought and dynamically reinforced by local firms through the development of intense, embedded customer–supplier relationships. Building on the relational view, we argue that this may happen through the commitment of resources to relation-specific investments. Our hypotheses find support in a sample of SMEs suppliers of ST Microelectronics, the fourth largest producer of microelectronic components in the world. We show that by making relation-specific investments, local firms can grow quantitatively and qualitatively, improve their innovativeness, and acquire new clients.     

Unobservable skill dispersion and comparative advantage

This paper investigates a theoretical mechanism linking comparative advantage to the distribution of skills in the working population. We develop a tractable multi-country, multi-industry model of trade with unobservable skills in the labour market and show that comparative advantage derives from (i) cross-industry differences in the substitutability of workers' skills and (ii) cross-country differences in the dispersion of skills. We establish the conditions under which higher skill dispersion leads to specialization in industries characterized by higher skill substitutability across tasks. The main results are robust when the model is extended to allow for partial observability of skills. Finally, we use distributions of literacy scores from the International Adult Literacy Survey to approximate cross-country productivity differences due to skill dispersion and we carry out a quantitative assessment of the impact of skill dispersion on the pattern of trade.     

Pricing Bonds and Bond Options with Default Risk

The pricing of bonds and bond options with default risk is analysed in the general equilibrium model of Cox, Ingersoll, and Ross (1985). This model is extended by means of an additional parameter in order to deal with financial and credit risk simultaneously. The estimation of such a parameter, which can be considered as the market equivalent of an agencies' bond rating, allows to extract from current quotes the market perceptions of firm's credit risk. The general pricing model for defaultable zero-coupon bond is first derived in a simple discrete-time setting and then in continuous-time. The availability of an integrated model allows for the pricing of default-free options written on defaultable bonds and of vulnerable options written either on default-free bonds or defaultable bonds. A comparison between our results and those given by Jarrow and Turnbull (1995) is also presented.
