Price transmission,foreign exchange rate risks and global diversification of ADRs

The purposes of this article are to reinvestigate how returns of major American depository receipts (ADRs) from different countries are related to the underlying stock returns and to identify the determinants of ADR risk premiums. We use different types of error-correcting terms in vector error correction models to examine information flows between ADRs and the underlying foreign stocks. General method of moments estimation of conditional international asset pricing model of Dumas and Solnik (1995 Dumas, B and Solnik, B. 1995. The world price of foreign exchange risk. Journal of Finance, 50: 445–79. [Crossref], [Web of Science ®] , [Google Scholar]) is applied to investigate ADR return premiums. We find that stock returns are more affected by disequilibrium between ADR and stock prices in an inefficient way. For US investors, foreign exchange rate risk premiums and world market risk premium (beyond US index) are priced in ADRs returns ex ante. Surprisingly, it is shown that the exchange rate of New Taiwan dollar and the interest rates of Brazil and Taiwan play important roles in determining ADR risk premiums across countries.     

Product diversification and bank risk: evidence from South Asian banking institutions

ABSTRACT

We investigate whether the product diversification activities of South Asian banking institutions have led to an increase or decrease in their solvency and profit risks. Using the data of five countries – India, Bangladesh, Nepal, Pakistan and Sri Lanka – for the period 2000–2016, we analyse the effect of both income and assets diversification activities on the Z-score and SDs of ROA (Return on Assets) and ROE Return on Equity). Among income diversification activities, securities trading income has a significant positive influence on bank risk while other categories have no influence. With respect to assets diversification, non-interest-bearing assets and loans given to government were found to have a significant positive influence on bank risk, while mortgage loans and non-classified loans have opposite influences. However, the impacts of securities trading income and loans given to the government are mainly confined to private sector banks and state-owned banks, respectively. We also uncover some country-specific diversification influences on the above relationships.     

Commodity Taxes, Wage Determination, and Profits

We examine the effects of two different types of commodity taxation, specific and ad valorem, on wages and profits. We analyze two models of wage determination, one with efficiency wage setting and one with union-firm bargaining. In the former, a (locally) revenue-neutral shift from specific to ad valorem taxation leads to an increase in both employment and wages and a reduction in profitability. In the latter, the effect on wages and profits may be reversed: predominantly ad valorem taxation raises employment but lowers wages, and under certain circumstances, the net effect is an increase in profits.     

Textbooks,Taxes, and Objectivity in Economics Instruction

Ignoring welfare gains from taxation biases conclusions about net welfare effects and about attitudes toward taxation. Examples are identified, and alternative, balanced treatments are presented.     

Nuclear Power, Externalities and Non-Standard Pigouvian Taxes

The external effects arising from the use of nuclear power are, in a fundamental way, related to uncertainty. In this paper we locate these external effects and derive a dynamic Pigouvian tax in order to make the decentralized economy support the command optimum. Another interesting result is that a small constant energy tax (which we interpret as a second best policy) can take the decentralized economy reasonably close to the command optimum.     

Currency substitution, portfolio diversification, and money demand

Abstract .  We extend the Thomas (1985) dynamic optimizing model of money demand and currency substitution to the case in which the individual has restricted or no access to foreign currency denominated bonds. In this case currency substitution decisions and asset substitution decisions are not separable. The results obtained suggest that the significance of an expected exchange rate depreciation term in the demand for domestic money provides a valid test for the presence of currency substitution. Applying this approach to six Latin-American countries, we find evidence of currency substitution in Colombia, Dominican Republic, and Venezuela, but not in Brazil and Chile.
