Motivated by the argument that central bank intervention leads to non‐linear exchange rate adjustment processes, we examine purchase power parity (PPP) by applying quantile unit root tests to the exchange rates of the New Taiwan Dollar (NTD) vis‐à‐vis seven Asian currencies. We show that exchange rate regime matters in determining whether PPP holds. While PPP holds overwhelmingly during the period when the NTD is under the fixed exchange rate regime, it is present only for some exchange rates during the managed floating rate regime. For exchange rates exhibiting mean reversion, the reversion occurs mainly when the shocks are large. In contrast to conclusion in the literature, our test results show little evidence of asymmetric mean reversion between positive and negative shocks. 相似文献

This study presents an annual macro-type econometric model of the Canadian agricultural sector. The model is designed to depict and forecast some of the important activities of the agricultural economy. This agricultural model is linked with a well established existing econometric model of the Canadian economy—the TRACE model. Forecasting results using the agricultural model with and without the linkage with the TRACE modfhtre discussed. Government expenditure multipliers of the TRACE model with and without the linkage of the agricultural model are also examined and discussed.

This paper analyses whether the use of imported intermediates improves productivity using firm‐level panel data of manufacturing firms in Ghana covering the period between 1991 and 2002. This includes examining the importance of absorptive capacity (ABC) in enhancing the productivity gains from imported intermediates. We propose lagged relative productivity as a new measure of ABC. For any given period, ABC is defined as the natural logarithm of a firm's total factor productivity (TFP) in the previous period relative to the firm's initial TFP. An alternative measure of ABC considers real value added per worker in lieu of TFP. Overall, we find that firms with high levels of ABC derive productivity gains from the contemporaneous and prior use of imported intermediates, particularly for firms operating in the input‐intensive industries. Our findings are robust to different specifications of the base model and different estimation techniques. 相似文献

We explore the effects of asymmetries in capacity constraints on collusion where market demand is uncertain and where firms’ sales and prices are private information. We show that all firms can infer when at least one firm's sales are below some firm‐specific ‘trigger level.’ When firms use this public information to monitor the collusive agreement, price wars may occur on the equilibrium path. Symmetry facilitates collusion but, if price wars are sufficiently long, then the optimal collusive prices of symmetric capacity distributions are lower on average than the competitive prices of asymmetric capacity distributions. We draw conclusions for merger policy. 相似文献

Competition among generics helps keep drug prices low and control medical costs. Good estimates of the effect on price of the entry of another generic competitor would inform competition policy and test oligopoly theories. However, identifying the causal effect of entry is difficult since the number of firms that compete in a market is endogenously determined. We exploit provisions of the 1984 Hatch–Waxman Act to identify a causal effect. We find that ignoring endogenous selection into generic drug markets imparts a significant downward bias to the estimates of the effects of two and three competitors on generic drug prices. 相似文献

Using nationally representative data from the Canadian Community Health Survey, we explored if the Vancouver 2010 Winter Olympics were associated with leisure-time physical activity rates among youth in Canada. No statistically significant changes were observed in the rate of moderately active/active youth in Canada or the province of British Columbia (BC) over the two-year time periods under investigation. At the regional level however, a significant increase in the rate of moderately active/active females from 2007–2008 (pre-event) to 2009–2010 (the year prior to the event and the year the event was staged) was observed in the Richmond, BC, health region (z = 2.05, p = .04). Previous conclusions that trickle-down effects do not occur are not supported by our data. Instead, we conclude that trickle-down effects may in fact occur, but may tend to be localised within certain communities (i.e. close to where Olympic events are staged) and among particular segments of a population. 相似文献
