Money,Bitcoin, and Monetary Policy

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.     

CAN SECRET INTERVENTION BE COMPATIBLE WITH A NON‐PROFITMAKING CENTRAL BANK AND A FUNDAMENTAL‐CONSISTENT TARGET?

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)     

MEASURING PRICE ELASTICITY OF SECTORIAL IMPORTS

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.     

Climbing the Job Ladder: New Evidence of Gender Inequity

An explanation for the gender wage gap is that women are less able or less willing to “climb the job ladder.” However, the empirical evidence on gender differences in job mobility has been mixed. Focusing on a subsample of younger, university‐educated workers from an Australian longitudinal survey, we find strong evidence that the dynamics of promotions and employer changes worsen women’s labor market position.     

PRICE DYNAMICS,FOREIGN EXCHANGE AND ANTICIPATED SHOCKS IN A TOURISM ECONOMY

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.

TAX REFORM

After brief individual presentations, panelists discuss among themselves and with the audience a broad spectrum of issues regarding various taxes and tax reform proposals. The discussion includes such issues as privatizing Social Security and Medicare, eliminating income tax withholding, and the merits and demerits of income taxes, consumption taxes, value added taxes, sales taxes, and taxes on resources that have an inelastic supply. One panelist relates his recent experiences using his tools as an economist to deal with tax and related issues as a current member of the Canadian Parliament. Another cites practical problems of implementing tax reform from his long experience advising governments, especially in Latin America. A major focus of the exchange of views is on public choice problems involved in passing and implementing a so-called flat tax. However, the discussion also deals with economic efficiency and equity considerations and with nearly all other types of taxes. The discussion includes not only the impact on the country within which tax reform occurs, but international implications, as well.
