This paper considers the small sample properties of the mean group estimator of the long-run coefficients in dynamic heterogeneous panels, and using Monte Carlo techniques examines the effectiveness of a number of alternative bias-correction procedures in reducing the small sample bias of these...

Experimental studies have been performed to investigate the thermal performances of woks fabricated from materials with different thermal conductivities and surface emissivities. A pre-mixed air/butane flame impinged vertically upwards upon a flat impingement-plate's (to simulate the wok's...

The coastal region in mainland China experiences typhoon wind hazard and risk. Since historical surface observations are scarce and of short period, the hazard assessment is often carried out using the typhoon wind field and track models. For a few major cities in the coastal region, there are...

It is widely recognized that nonagricultural earnings are crucial for the welfare of rural households in developing countries. In this study, we investigate whether workers close to cities are paid higher nonagricultural wages than workers in outlying rural areas. We find that workers close to...
