Abstract This paper first presents stylized evidence showing how the date of the adoption of competition policy is correlated with country size. Smaller countries tend to adopt competition policy later. We then present a theoretical model with countries of different size, trade costs, and firms competing à la Cournot. In the model we show that reduced trade costs following from increasing globalization affect countries differently depending on their size. This has implications for the incentives to introduce competition policy. The predictions of the model are consistent with the empirical regularity presented.  相似文献

A general equilibrium theory with heterogeneous skills predicts a complementarity between trade and democracy in creating demand for superior technologies. Trade liberalization or democratization alone may lead to vested interests that limit technology adoption. We use panel data on technology adoption, at a disaggregated level, for the period 1980–2000. Exploiting within-country variation over time and the heterogeneous timing of trade liberalization and democratization, we document a significant and sizable positive interaction between trade openness and democratization for technology adoption. The result that transitions to open democracies are beneficial for technological dynamics is robust to a large set of checks.  相似文献

In contrast to Mundell's inquiry on the optimality of currency areas, this article aims to understand under what circumstances a Pareto‐dominant monetary union will be established. Using a multicountry overlapping generations model, we highlight gains from monetary union arising from reduced transactions costs and lower inflation. Despite these gains, countries acting independently will impose barriers to exchange through local currency restrictions, thereby creating transactions costs and providing an incentive for inflation. Therefore, the gains from monetary union are most likely to be lost without collective effort.  相似文献

We present a model of capital accumulation and technology adoption in a vintage-capital framework. The model is an infinite-horizon/infinite-dimensional optimal control model: the firm employs a continuum of technologies (a continuum of heterogeneous capital goods). Capital goods are technology specific, their technology is related to vintage and technology progress. The entrepreneur maximizes the profits obtained by employing a continuum of technologies under the assumption of constant returns to scale and bearing adjustment costs for gross investments. The diffusion of a new technology is established by allowing the entrepreneur to invest in vintage capital goods.  相似文献

The introduction of packet-switched telephony in the form of Voice over Internet Protocol (VoIP) raises concerns about current regulatory practice. Access regulation has been designed for traditional telephony on public networks (PSTN). In this paper we analyze the effect of access regulation and retail price regulation of PSTN networks on the adoption of a new technology in the form of VoIP. In particular, we show that with endogenous consumer choice between PSTN and VoIP telephony, higher prices for terminating access to the PSTN network make VoIP less likely to succeed and lead to lower profits of operators that offer exclusively VoIP telephony.   相似文献

This paper presents a one‐primary factor, two‐consumer good, and two‐country model of international trade where each country’s government supplies a country‐specific public intermediate good so as to attain efficient production. By introducing the Marshallian adjustment process, it is demonstrated that the country with larger factor endowment exports the good whose productivity is more sensitive to the public intermediate good. Our normative analysis of free trade shows the following results. First, at least one country gains from trade. Secondly, if a country incompletely specializes in the trading equilibrium, the country necessarily loses from trade.  相似文献

Why do 20% of Swedes report having adopted a clean energy system while the corresponding share of Spaniards equals 0.4%? Using data for about 25,000 individuals across 33 countries, this study tests which cultural trait, individualism or collectivism, is associated with greater levels of clean technology adoption. Our fractional probit estimates suggest that individualistic individuals are more inclined to adopt clean energy systems for home and transport purposes. In particular, the adoption probability rises by an estimated 2% if a person exhibits individualistic values. This finding is not driven by country-specific tax or subsidy policies or market-specific determinants and is robust to controlling for individual and household characteristics, attitudes, social and personal norms and other significant dimensions of cultural differences. The results, therefore, facilitate an understanding of how the decision to adopt clean energy technologies can be driven by cultural factors.  相似文献

Recent studies have suggested that institutional and economic factors are important drivers of financial inclusion. However, the effects of culture on the usage and adoption of formal financial services are not as widely understood. This paper explores the impact of religiosity on financial inclusiveness, utilizing aggregated data from individuals’ religious preferences and financial behaviors. The results suggest that higher levels of religiosity are negatively associated with the usage and adoption of formal financial services, both across U.S. states and across different countries. To explore possible causal implications, we exploit spatial variations in historical pathogen prevalence as the main instrument of our study.  相似文献

We examine the effects of free trade agreement (FTA) on tariffs and welfare in a three‐country model with vertical trade, where an FTA is formed between a country exporting a final good whose production involves using an intermediate good, and a country exporting the intermediate good in exchange for the final good. We demonstrate that the FTA reduces its member country's external tariff, whereas it raises the non‐member country's tariff. The non‐member country unambiguously becomes better off. In contrast, the FTA may or may not make its member countries better off. This implies that the formation of an FTA may not always be Pareto‐improving.  相似文献

Summary. This study develops a real options approach for analyzing the optimal risk adoption policy in an environment where the adoption means a switch from one stochastic flow representation into another. We establish that increased volatility does not necessarily decelerate investment, as predicted by the standard literature on real options, once the underlying volatility of the state variable is made endogenous. We prove that for a decision maker with a convex (concave) objective function, increased post-adoption volatility increases (decreases) the expected cumulative present value of the post-adoption profit flow, which consequently decreases (increases) the option value of waiting and, therefore, accelerates (decelerates) current investment.Received: 12 October 2001, Revised: 4 December 2002, JEL Classification Numbers: O32, G30, D92, C61.

We explore how broadband access drives changes in the quantity and diversity of consumption of online content by using panel data that describes household Internet usage before and after broadband adoption. Our data suggests that on average, broadband adoption increases usage by over 1300 min per month. We also find that information consumption becomes more evenly distributed within the population, driven in part by post-adoption usage gains of almost 1800 min per month among individuals who were in the lowest usage quintile before adopting broadband. After adopting broadband, this pre-adoption lowest-usage quintile consumes content in greater quantities than users in neighboring quintiles, passing both the second and third quintiles in terms of absolute usage. This suggests that these users may have had strong preferences for high-bandwidth content that was too costly to consume in a narrowband environment. We also show that broadband adoption increases the variety of content that users consume although many of these gains appear to be associated with an increase in the variety of sites visited within previously visited content categories rather than an expansion in the types of content consumed.  相似文献

In this paper, a framework is developed to analyze how the specifications of new technologies and the heterogeneity of micro-units of production affect the input use, the adoption pattern, and the productivity of inputs. It shows that asset-productivity-enhancing (APE) technologies tend to be adopted by micro-units with high-quality assets, while variable-input, efficiency-enhancing (VIEE) technologies tend to be adopted by micro-units with low-quality assets. In both cases, the variable input productivity increases, but the average productivity of the fixed asset may decline in the case of the VIEE technology. The distribution of asset quality and the new technology specifications will therefore determine the impacts of production technology innovations on aggregate behavior and consequently the change in average productivity of the fixed asset.  相似文献

In a duopoly framework we show that among the set of firms competing with the technology leader, both relatively advanced and relatively backward firms will not be likely adopters of the superior technology. Instead, the firms in the “middle” will invest for adopting the superior technology. This particularly characterizes the innovation characteristic of LDC markets where backward firms exist along with technology super-powers.  相似文献

Supply security and environmental concerns associated with oil call for an introduction of hydrogen as a transport fuel. To date, scenario studies of infrastructure build-up and sales of fuel cell vehicles (FCVs) are driven by cost estimates and technological feasibility assumptions, indicating that there is a “chicken and egg problem”: Car producers do not offer FCVs as long as there are no hydrogen filling stations, and infrastructure will not be set up unless there is a significant number of FCVs on the road. This diffusion barrier is often used as an argument for a major (public) infrastructure program, neglecting the fact that the automobile market is highly competitive and car producers, consumers, and filling station operators form an interdependent dynamic system, where taxes influence technology choice. In this paper, an agent-based model is used that captures the main interdependencies to simulate possible diffusion paths of FCVs. The results suggest that a tax on conventional cars can successfully promote diffusion even without a major infrastructure program. However, consumers and individual producers are affected differently by the tax, indicating that differently strong resistance towards such a policy can be anticipated. Moreover, there is evidence that some producers might benefit from cooperation with filling station operators to generate a faster build-up of infrastructure.

It is well known that the design of cost minimizing procurement rules for the selection of a contractor among distinct technological groups requires the favouritism of inefficient firms. In this paper, I show that, if technology adoption is non-contractible, these policies will also provide optimal incentives for the inefficient firms to adopt more efficient technologies.  相似文献

A modified version of the partial‐equilibrium gravity model, originally proposed by Fukao et al. (2003 ), is employed to investigate the changing pattern of US textile trade. We use US Bilateral Manufacturing Imports and Exports data for 1989–2001 to assess the impact of labor wages, tariffs, and exchange rates on the composition of US textile imports before and after the creation of NAFTA. The analysis is performed at the SIC two‐digit industry level and the more disaggregated four‐digit sector level. We find little evidence of trade diversion in textiles frequently attributed to NAFTA, while trade creation is clearly present. Furthermore, lower wages in some textile‐exporting countries (e.g. countries in Asia) do not appear to significantly increase these countries' shares of US textile imports at the expense of other trading partners. However, variations in currency exchange rates and tariffs have substantial effects on the composition of US imports.  相似文献

We studied how the pursuit of bilateral free‐trade agreements (FTAs) affects the likelihood of achieving multilateral free trade. We derive and compare the stable Nash equilibria of two games of trade liberalization: in the FTA game, each country can either form an FTA with one of its trading partners or both of them or none of them, whereas in the (restricted) No FTA game, purely bilateral FTAs are not permitted. The major result is that there exist circumstances under which the freedom to pursue (discriminatory) bilateral FTAs is necessary for achieving multilateral free trade.  相似文献
