MINIMUM WAGES,IMPORT STATUS,AND FIRMS' INNOVATION: THEORY AND EVIDENCE FROM CHINA

This study explores the heterogeneous effects of minimum wage on innovation of different types of firms. We develop an open‐economy R&D‐based growth model and obtain the following result: raising the minimum wage reduces innovation of firms that use domestic inputs but increases innovation of firms that import foreign inputs. We test this result using city‐level data on minimum wages and firm‐level patent data in China. In accordance with our theory, we find that raising the minimum wage is associated with more innovation by importing firms and less by non‐importing firms. This result survives a battery of robustness checks. (JEL E24, F43, O31)

Forecasting the spot price of gold:combined forecast approaches versus a composite forecast approach

The fluctuation of the gold price has significant impact on the economic and social aspects of a society. In the literature, most authors have employed fundamental analysis approach in forecast model building. The basic principle underlying this approach is that it is the supply and the demand which simultaneously determines the gold price. However, due to the lack of data of quantity supplied and quantity demanded, simultaneous econometric approach seems unsuccessful. In this paper, combined and composite time series forecasting techniques are proposed. The effects of various economic factors towards spot price of gold are also examined. Among the combined forecasting models, it seems that the odds-matrix method of assigning weights provides the most accurate forecasts of spot price of gold. For the economic factors considered, the futures price of gold and and the exchange rate seem to be most informative in forecasting the spot price of gold.
