Summary. We seek to explain the economic volatility of the last 6 years, in particular the rapid expansion and contraction of the knowledge sectors. Our hypothesis is that these sectors amplify the business cycle due to their increasing returns to scale, growing faster than others in an upswing and contracting faster in a downswing. To test this hypothesis we postulate a general equilibrium model with two sectors: one with increasing returns that are external to the firm and endogenously determined - the knowledge sector - and the other with constant returns to scale. We introduce a new measure of volatility of output, a real beta, and derive a resolving equation, from which we prove that the increasing return sectors exhibit more volatility then other sectors. We validate the main results on US macro economic data of real GDP by industry (2-3 digits SIC codes) of the 1977-2001 period, and provide policy conclusions.Received: 18 March 2002, Revised: 16 February 2004, JEL Classification Numbers:

We compare a number of models of post War US output growth in terms of the degree and pattern of non-linearity they impart
to the conditional mean, where we condition on either the previous period's growth rate, or the previous two periods' growth
rates. The conditional means are estimated non-parametrically using a nearest-neighbour technique on data simulated from the
models. In this way, we condense the complex, dynamic, responses that may be present in to graphical displays of the implied
conditional mean.

Summary. The purpose of this paper is to consider environmental taxation which would control emissions of firms in a model of growth
cycles. In the model presented below, the economy may experience two phases of growth and environmental quality: “the no-innovation
growth regime” and “the innovation-led growth regime”. Aggregate capital and environmental quality remain constant in the
no-innovation growth regime, while they perpetually increase in the innovation-led growth regime. The paper shows that the
tax plays a key role in determining whether the economy stably converges to one of the two regimes or fluctuates permanently
between them. It also shows that there is a critical level of the tax and that the economy obtains higher growth rates of
capital and environmental quality by raising (or reducing) the tax if the initial tax is below (or above) the critical level.

This paper conducts a statistical analysis of post-war economic fluctuations in Italy. It is argued that business cycles in this country qualitatively conform to the general character of the phenomenon, a result which confirms existing evidence. A temporal stability analysis of stylized facts shows that some statistically significant changes in the empirical regularities occurred after 1973, but they did not alter the main qualitative features of the business cycle. The evidence thus supports interpretative models of the Italian business cycle which incorporate a stable propagation mechanism. 相似文献

A two-sector growth model with endogenous technical change is presented. Concerning technical change, we assume that it is reflected by increases in the stock of human capital which are acquired through learning by doing. As a result, it turns out that transitory or, using the Hopf bifurcation theorem, persistent oscillations of the economic variables may be the outcome. Thus we are able to show that learning mechanisms alone may be sufficient to destroy the circular flow as described by Schumpeter. 相似文献

We find that initial returns were more favorable for Internet initial public offerings (IPOs) than non–Internet firm IPOs. Since the demise of the Internet sector, the underpricing of Internet–firm IPOs is not significantly different from other IPOs.
Initial returns of Internet firms are positively and significantly related to underwriter prestige and to pre–IPO market conditions. However, initial returns after the demise of the Internet sector are not significantly related to these characteristics.
The aftermarket performance of Internet firms is initially favorable but weakens over time. Firms that experienced higher initial returns during the strong Internet cycle experience weaker aftermarket performance. 相似文献
