The transesterification of boronate esters with diols is tunable over at least 14 orders of magnitude. Rate acceleration is achieved by internal base catalysis, which lowers the barrier for the proton transfer step. Here we report a photoswitchable internal catalyst that tunes the rate of boronic ester/diol exchange over at least 4 orders of magnitude. We employed an acylhydrazone molecular photoswitch, which forms a thermally stable but photoreversible intramolecular H-bond, to gate the activity of the internal base catalyst in 8-quinoline boronic esters. The photoswitch can be cycled repeatedly, with high photostationary states. The intramolecular H-bond is found to be essential to the design of this photoswitchable internal catalyst, as protonating the quinoline with external sources of acid has little effect on the exchange rate.

After the financial crisis at the end of the 1990 s many countries rejected fixed exchange rate policy. However actually they failed to proceed to announced "independent float" exchange rate arrangement. This might be due to the "fear of floating" or an irreversible result of inflation targeting central bank policy. In the article advantages and drawbacks of fixed and floating exchange rate arrangements are systematized. Features of new returning to exchange rates stabilization and possible risks of such policy for Russia are considered. Special attention is paid to the issue of choice of a "target" currency composite which can minimize external inflation pass-through.

Rate Risk

This study aims to analyze economic exposures and its factors namely exchange rates and inflation, that influence firm value as reflected through firm cash flow. Analytical method used Ordinary Least Square and eviews as analytical tool. This study used secondary data and cigarette industry companies listed on the Indonesia Stock Exchange as samples along 2008 to 2017. Samples choosing method used purposive sampling based on determined criterias. The results showed that partially economic exposure had positive effects on firm value but insignificant. These could be seen from the economic exposure factors influncenced namely exchange rates and inflations.The exchange rate risk has low influenced cash flow was caused of the tobacco industry has low level of export/import.Enhance,inflation also had low effect on cash flow was caused of the tendency of cigarette consumers will continue to buy cigarettes even though its price increases. In short, economic exposure in the tobacco industry has low influence toward firms value. Hence, simultaneously changes in exchange rates and inflation which are economic exposure indicators have a significant effect on cash flows.  Keywords: Economic Exposure, Exchange Rate Risk, Inflation Risk, Firms Value, Cash Flow

Floating Exchange Rate

This study examined the effect exchange rates have on import and export volumes under alternative exchange rate policies adopted in South Africa over the period 1960 to 2017. Using quarterly time series data for the stated period, a log-linear error correction model is employed to estimate the country’s export and import elasticities, taking into account Gross Domestic Product (GDP), the real price of exports, the real price of imports and real exchange rates. Using the freely floating exchange rate regime as the base period, the study concluded that both export and import volumes are lower under a system of fixed exchange rates. Export and import volumes were also found to be lower under the dual exchange rate regime, relative to the freely floating exchange rate regime. In accordance with export-led growth strategies, exports were found to be higher and imports lower under a managed floating exchange rate regime. It is therefore recommended that South Africa revert to a more managed exchange rate regime, until the South African economy is developed to accommodate a freely floating exchange rate regime.

The level of return obtained by investors is influenced by microeconomic and macroeconomic factors. This study aims to obtain empirical evidence regarding the effect of exchange rates, Gross Domestic Product and solvency on stock returns. This research was conducted at the mining company in the coal sub-sector on the Indonesia Stock Exchange. All the coal mining sub-sector companies listed on the Stock Exchange for the period 2014-2017 used as the population. The method of determining the sample used is using a saturated sampling technique. Multiple linear regression test used as the data analysis on this research. Based on the results of the analysis of this study it was found that the exchange rate and GDP had a negative and significant effect on stock returns. The solvency proxied by DER has a positive and significant effect on stock returns. Keywords: Exchange Rate, Gross Domestic Product, Solvability and Return.

This paper revisits the association between exchange rates and monetary fundamentals with the focus on both linear and nonlinear approaches. With the monthly data of Euro/US dollar and Japanese yen/US dollar, our linear analysis demonstrates the monetary model is a long-run description of exchange rate movements, and our nonlinear modelling suggests the error correction model describes the short-run adjustment of deviations of exchange rates, and monetary fundamentals are capable of explaining exchange rate dynamics under an unrestricted framework.

Exchange Rate Fluctuations

What keeps the three major industrial blocs -- Western Europe, North America, and industrialized Asia -- from developing a common monetary standard to prevent exchange-rate fluctuations? One important reason is the differing theoretical perspectives of economic advisers. The first issue is whether or not a floating foreign exchange market -- where governments do not systematically target exchange rates -- is “efficient.” Many economists believe that exchange risk can be effectively hedged in forward markets so international monetary reform is unnecessary. Second, after a decade and a half of unremitting turbulence in the foreign exchange markets, economists cannot agree on “equilibrium” or desirable official targets for exchange rates if they were to be stabilized. The contending principles of purchasing power parity and of balanced trade yield very different estimates for the “correct” yen/dollar and mark/dollar exchange rates. Third, if the three major blocs can agree to fix nominal exchange rates within narrow bands, by what working rule should the new monetary standard be anchored to prevent worldwide inflation or deflation? After considering the magnitude of exchange-rate fluctuations since floating began in the early 1970s, I analyze these conceptual issues in the course of demonstrating how the central banks of Japan, the United States, and Germany (representing the continental European bloc) can establish fixed exchange rates and international monetary stability.

Abstract We provide a theory of the determination of exchange rates based on capital flows in imperfect financial markets. Capital flows drive exchange rates by altering the balance sheets of financiers that bear the risks resulting from international imbalances in the demand for financial assets. Such alterations to their balance sheets cause financiers to change their required compensation for holding currency risk, thus affecting both the level and volatility of exchange rates. Our theory of exchange rate determination in imperfect financial markets not only helps rationalize the empirical disconnect between exchange rates and traditional macroeconomic fundamentals, it also has real consequences for output and risk sharing. Exchange rates are sensitive to imbalances in financial markets and seldom perform the shock absorption role that is central to traditional theoretical macroeconomic analysis. Our framework is flexible; it accommodates a number of important modeling features within an imperfect financial market model, such as nontradables, production, money, sticky prices or wages, various forms of international pricing-to-market, and unemployment.
