The coexistence of secret intervention operations and “the signaling channel” (Mussa. The Role of Official Intervention, 1981) seems confusing. Vitale ( Journal of International Economics, 49, 1999, 245–267) resolves this puzzle by employing an asymmetric information framework and an assumption of a fundamental‐inconsistent target for the exchange rate. Ferré and Manzano ( International Journal of Finance and Economics, 14, 2009, 378–393) follow Vitale's microstructure framework and argue that the central banks' profitability motivation offers a rationale for their secret intervention even under a target consistent with the fundamentals. However, that the authority uses its superior information to obtain speculative profits through secret intervention in the market is not a typical goal for central banks. To theoretically explain the opaqueness in non‐profitmaking central banks' exchange rate policies, we employ a model of a central bank's optimization by considering that no bank really knows the exact fundamental rate and they take into account the possible bad consequences of announcing the intervention. We also show that, in passing the bank's private information to market participants, a bank's announcement of the intervention size is equivalent to revealing its target rate. (JEL E58, F39) 相似文献

A search-theoretic model is constructed, where money and Bitcoin can be used as mediums of exchange. We investigate how each currency facilitates transactions and how they compete with each other. Quantitative analysis shows that welfare in an economy with both money and Bitcoin is lower than in a money-only economy due to congestions in the confirmation of Bitcoin transactions and that the welfare gap between the two economies expands as inflation rises. Moreover, an increase in transaction fees for Bitcoin can increase welfare by reducing inefficient Bitcoin transactions. 相似文献

Probing into the incidence of job displacements during the 1997–99 recession period, this study offers theoretically grounded micro‐causal explanations for regional ties and regional discrimination in South Korea. Our statistical analysis reveals the significant impact of a worker's birth region (the basis of regional ties and discrimination) on the layoff process. Native Kyongsang workers are found to have faced higher rates of layoff in Seoul‐Kyongki regional firms than native Jolla workers during the recession period. The Kyongsang–Jolla layoff rate gap is mainly due to differential treatment rather than a difference in observable characteristics. The findings suggest that the problem of regional ties and regional discrimination is more deep‐rooted and widespread in South Korea than previously reported. 相似文献

为了掌握福鼎市桐江溪卤乙酸(HAAs)的含量、时空分布规律及其来源,对水体中HAAs化合物进行取样调查。根据桐江溪水文情势及沿岸特点设置10个取样点,于2017年12月及2018年7月按照涨潮、退潮情况分别对水样进行采集,检测HAAs分布情况,同时将卤乙酸(HAAs)与水质特性、涨退潮进行了相关性分析。研究发现,HAAs是普遍存在于桐江溪中的污染物质。其中,一氯乙酸(MCAA)、二氯乙酸(DCAA)、三氯乙酸(TCAA)、一溴乙酸(MBAA)、二溴乙酸(DBAA)等5种卤乙酸(HAA_5)质量浓度为0.44~3.39μg/L;一氯乙酸(MCAA)、二氯乙酸(DCAA)、三氯乙酸(TCAA)、一溴乙酸(MBAA)、二溴乙酸(DBAA)、三溴乙酸(TBAA)、一溴一氯乙酸(BCAA)、一溴二氯乙酸(BDCAA)、二溴一氯乙酸(CBDAA)等9种卤乙酸(HAA_9)质量浓度为0.83~56.15μg/L。桐江溪中HAAs主要为DCAA,TCAA,TBAA 3种,其中DCAA为制药厂及医院排水导致,主要分布在下游;TCAA主要来源于河段上游的农业生产活动;TBAA为上游沸石矿尾矿库受雨水冲刷而流入的Br~-所生成,主要分布于河流中下段。相关性分析结果表明,温度与HAA_5,HAA_9质量浓度呈现正相关,pH值与HAA_5,HAA_9质量浓度呈现负相关;TCAA质量浓度于相同季节不同潮汐及不同季节相同潮汐时均呈现上游高于下游的现象,其他HAAs均不因涨潮、退潮的差异造成质量浓度分布的变化。掌握桐江溪HAAs的含量、时空分布规律及来源,探讨其与水质的相关性,对于净水工艺选择、水厂出水HAAs含量的溯源分析、水体环境风险评估以及研究水生生物体内HAAs的累积效应等有重要意义。 相似文献

Previous published studies have estimated the long‐run cointegrating relationship to infer the price elasticity of imports, but a stable long‐run cointegrating relationship might not be detected in the data, especially in the case of sectoral data. This paper develops a method to estimate the price elasticity of imports based on a vector autoregression model, which can be applied when a stable long‐run cointegration relationship does not exist. The methods developed in past studies and our method are applied to Korean sectoral imports data to illustrate the usefulness of our method. 相似文献

Using a dynamic model of an open monetary economy, this paper examines the effects of tourism‐related anticipated shocks on goods prices and foreign exchange reserves. Foreign tourists consume mainly non‐traded goods in holiday destinations, converting them into exportable goods. This gives rise to a tourism terms‐of‐trade effect that affects the accumulation of foreign exchange. Announcements of anticipated events bring tourist visits forward, resulting in an initial under‐adjustment or an over‐adjustment in the prices of the non‐traded goods when the tourism terms‐of‐trade effect is positive or negative. This leads to an increase or a decrease in foreign reserves in the long run. 相似文献

We investigate ethnic minority and nonminority sell-side analysts’ participation in public earnings conference calls. We find that minority analysts are underrepresented in conference call Q&A sessions, and minority analysts who do participate on the calls experience lower levels of prioritization than do nonminority analysts. Minority analysts’ lower participation rates are partially but not fully mediated by characteristics such as experience, work environment, and stock rating favorability. Additionally, firm and conference call fixed effects mediate approximately half the magnitude of lower minority participation rates. Extroverted minority analysts participate at higher rates, but the negative association between minority status and conference call participation is exacerbated when calls are more time constrained, when executive teams are less diverse, and when analysts are from less prestigious brokerage houses. Overall, we document the underrepresentation of minority analysts on earnings conference calls and provide evidence suggesting both analysts’ and managers’ choices influence minority analysts’ participation rates. 相似文献

This paper examines the effect of monetary policy on the market value of the liquidity services that financial assets provide, known as the liquidity premium. The theory predicts that money supply and nominal interest rates have positive effects on the liquidity premium, but asset supply has a negative effect. The empirical analysis with U.S. data confirms the theoretical predictions. The theory also proposes that the liquidity properties of assets can cause negative nominal yields when the money holding cost is low and liquid assets are scarce. The suggestive empirical findings in Switzerland to support this theoretical result are presented. 相似文献

This paper reports the results of a survey of students with and without prior knowledge of accounting with a view to identifying any differences in their perception of the relevance of current prices of assets.
The combination of cash flows and net realizable values appears to have an intuitive appeal to students with no prior exposure to accounting concepts or practices. In the process of learning about accounting, it seems that students learn to abandon net realizable values in favour of historical costs. 相似文献
