Apparatus for use in the production of ribbon-shaped crystals from a silicon melt

A susceptor for facilitating induction heating of silicon melt is described. The susceptor comprises a pair of susceptor halves of a thickness less than two skin depths, each being the mirror image of the other, disposed in mutually opposed, electrically insulated relation. The crucible comprises a quartz body supported by the graphite susceptor, whereby the R-F coil is electrically coupled with the melt

Convergence behaviour in exogenous growth models

This paper analyzes several aspects of convergence behaviour in the Solow growth model. In empirical work, a popular approach is to log-linearize around the steady-state. We investigate the conditions under which this approximation performs well, and discuss convergence behaviour when an economy is some distance from the steady-state. A formal analysis shows that convergence speeds will be heterogeneous across countries and over time. In particular, the Solow model implies that convergence to a growth path from above is slower than convergence from below. We find some support for this prediction in the data.convergence, economic growth, Solow model

Rich Nations, Poor Nations: How much can multiple equilibria explain?

The idea that income differences between rich and poor nations arise through multiple equilibria or 'poverty traps' is as intuitive as it is difficult to verify. In this paper, we explore the empirical relevance of such models. We calibrate a simple two sector model for 127 countries, and use the results to analyze the international prevalence of poverty traps and their consequences for productivity. We also examine the possible effects of multiplicity on the world distribution of income, and identify events in the data that may correspond to equilibrium switching.

Means for growing ribbon crystals without subjecting the crystals to thermal shock-induced strains

A susceptor particularly suited for use in growing a ribbon crystal employing edge defined film fed growth techniques is described. The susceptor includes a die through which a melt is drawn for forming a crystal ribbon. This is combined with a coolant delivery system characterized by a pair of jets for directing a stream of fluid coolant along a path extended to impinge on the susceptor in close proximity with the die in nonincident relation with the crystal being grown

Rich nations, poor nations: how much can multiple equilibria explain?

This paper asks whether the income gap between rich and poor nations can be explained by multiple equilibria. We explore the quantitative implications of a simple two sector general equilibrium model that gives rise to multiplicity, and calibrate the model for a large number of countries. Under the assumptions of the model, around a quarter of the world’s economies are found to be in a low output equilibrium. The output gains associated with an equilibrium switch are sizeable, but well short of the vast income disparity observed in the data.poverty traps, multiple equilibria, TFP differences,calibration
