The adoption and diffusion of inputs in the production network is at the heart of technological progress. What determines which inputs are initially considered and eventually adopted by innovators? We examine the evolution of input linkages from a network perspective, starting from a stylized...

This paper provides a survey of recent growth models that attempt to explain the cross-country diversity in rates of economic growth. It shows that these models can only generate differences in growth rates in the absence of international capital markets. With free international capital mobility...

In this paper we argue that modelling the trend component in real GNP as a random walk is inconsistent with its interpretation as productivity growth. As an alternative we specify the trend as an Auto Regressive Integrated Moving Average (ARIMA) process, whose impulse response function follows...

We argue that a sensible measure of the aggregate value of human capital is the ratio of total labour income per capita to the wage of a person with zero years of schooling. The reason is that total labour income not only incorporates human capital, but also physical capital: given human...

The search for and dating of a possible european business cycle, has been inconclusive. At this stage, there is no consensus on the existence of such a cycle, or of its periodicity and amplitude, or of the relationship of individual member countries to that cycle. Yet cyclical convergence is the...

Many papers have explored the relationship between average tariff rates and economic growth, when theory suggests that the structure of protection is what should matter. We therefore explore the relationship between economic growth and agricultural tariffs, industrial tariffs, and revenue...

We construct a set of human capital indexes for the states of the United States for each Census year starting in 1940. To do so we propose a new methodology for the construction of index numbers in panel data sets. Our method is based on an optimal approach by which we choose the `best' set...

The paper shows how prolonged price inertia can arise in a macroeconomic system in which there are temporary price rigidities as well as production lags in the use of intermediate goods. In this context, changes in product demand -- generated, say, by changes in the money supply -- have...

The rise of the People’s Republic of China (PRC) in world trade has brought both benefits and anxiety to other economies. For many policy questions, it is crucial to know the extent of foreign value added (FVA) in exports. We review a general formula in Koopman, Wang and Wei (2008) for...

This paper develops a novel theory of trade in a global supply chain. We expand on a monopolistic competition trade model. Countries produce both intermediate and final goods that are sold domestically or, incurring country-pair specific trade costs, internationally. This links countries in a...
