Foreign Exchange and BSE/ELR Programs

Opening Statements

This is a follow-up discussion related to my original inquiry on February 24 regarding a BSE program and floating or flexible exchange rates. I appreciate the responses from Davidson, O’Donnell, Mosler and Forstater. These initial responses have lead me to review what little material I could find on how instituting a BSE/ELR type of program might affect the balance of payments. Concurrent to this issue is whether a fixed or flexible floating rate exchange is the ideal choice. In the following discussion, I will try to outline my analysis of the information and hopefully instigate further discussion of this important policy issue in addressing problems of unemployment, price stability and balance of payment questions. The complete references used in this study are provided at the end.

To set the stage for this discussion, let me first state that the implementation of a BSE/ELR type of program is a desirable policy goal. Given the tenets of functional finance, as excellently discussed by Randy Wray in his latest book, the ability for a government to implement this program is accepted as correct. Therefore, the discussion of whether this is desirable or even obtainable is set aside. Equally the issue of whether "fiat" money is indeed tax driven, as outlined by Mosler, Mitchell, Wray and Forstater, is accepted as a "sufficient" if not a necessary reason for determining the value of a fiat currency. The ability to maintain stable prices by this monetary policy is accepted. Thus my focus is upon the conditions of international exchange and how domestic policies to eliminate unemployment affect this exchange.

The focus of the discussion is the writings of the proponents of a BSE/ELR type of program that stress the need for "flexible" exchange rates in this type of policy implementation. Against this background are the writings of Davidson that stress a return to a "fixed" exchange rate to control the de-stabilizing effects of rapid capital flows in the international community. While Davidson does not specifically address this issue within the backdrop of a BSE/ELR program, inferences can be drawn from his work with regard to the desirability of a fixed exchange rate under this type of domestic program.

A brief digression into historical analysis is needed at this point. Until the early 1970’s, most of the major world economies operated under a fixed exchange rate regime. Davidson notes that during the period from 1950 to 1973, the real growth rate of the GDP for OECD nations was almost twice the peak of the industrial revolution. Since 1973, when flexible exchange rates returned, growth has been almost half the 1950 to 1973 period. Equally in this period, unemployment has reached double digit levels in many of the OECD economies (1998a, pp. 3-4). Steady growth is desirable in order to help offset any inflationary tendencies that will arise when a government maintains a deficit monetary policy that would arise from the BSE/ELR program. Additionally, with the return to flexible exchange rates since the 1970’s, the growth in daily volume of international exchange has grown enormously. It is estimated the daily global turnover on the organized exchanges in 1998 was $1.599 trillion (Cross, 1998, p. 5). Due to this enormous growth in international volume, the ability of governments to make and implement domestic monetary and fiscal policies are said to be diminished. This particularly becomes true when continuous and persistent deficits or surpluses occur within one country’s balance of trade. (Although the US may represent one situation that has tended to avoid any major detrimental effects from its persistent deficit due the $ being used as a "store of value" or as a "vehicle" for international transactions.) Thus with the implementation of a BSE/ELR type of program, analysis must be provided on how this will affect the current balance of trade position.

Discussion

Mosler, in "Exchange Rate Policy and Full Employment," and Mosler and Forstater, in "A General Analytical Framework for the Analysis of Currencies and Other Commodities," and Mitchell, in "The Buffer Stock Employment Model in a Small Open Economy," have provided a starting point to begin an analysis of this issue. Beginning with Mosler’s work, Mosler states, "The combination of BSE and floating exchange rates directly insures sustained full employment by definition and should promote favorable terms of trade as later discussed" (p. 1). Mosler goes on to analyze two situations in which the exchange rate was essentially "fixed" to the $US. The first is an analysis of Russia that was unable to set its interest rate exogeneously due to the convertibility of rubles for $ at the CB. With the suspension of convertibility in August of 1998, the result is said to be a floating exchange rate regime in which Russia can now practice functional finance to remedy its situation. Thus a BSE/ELR type of program could be instituted without further drains of its $US reserves.

The other example was centered on the "currency board" regime in HK. In order for HK to implement a BSE/ELR program, it would have to obtain more $ US to protect its reserves. In this example, the exchange is fixed to the $US putting a constraint on domestic independence. Based on these two situations, Mosler states:

"If a government chooses a fixed exchange rate policy, and simultaneously attempts to achieve full employment, it could very well lose its foreign exchange reserves. Interest rates would be rising, as expressed by the forward price of the
currency falling while the spot price is being supported by a diminishing pool of
fx reserves" (p. 8).

Thus for Mosler, in order for a BSE/ELR program to be effective, flexible exchange rates are needed.

A similar analysis is found in the Mosler and Forstater work. In analyzing the Asian Crisis of 1997, they state that the maintenance of a "pegged exchange rate," another type of fixed exchange, set up a situation that proved destabilizing. The results of this peg are described as:

However, when the private sector turned to being net sellers of the local currency
to pay their $US obligations the central banks were reluctant to lose their $US
reserves to support the local currency and instead let it float downward. At the
lower foreign exchange rates the local businesses were unable to meet their $US
obligations and a liquidity crisis, which is still not resolved followed (pp. 8-9).

From this discussion, it can be inferred that a fixed exchange rate was disastrous for the local currencies. Due to the "pegged" nature of the exchange, any attempt to implement a BSE/ELR program would either drain $US reserves or cause further devaluation of the currency with its attendant inflationary effects. Price stability is undermined and unemployment increases. This is readily exemplified Asian contagion over the last two years.

Mitchell continues this line of thought in the analysis of inflation and short/long interest rates in connection with a BSE/ELR program. From this comes the important conclusion that,

Under fixed exchange rates, globalisation of financial markets lead to a convergence of both short-term and long-term interest rates across countries within the exchange rate bloc. The rates also tend to move together and are thus determined by shared conditions. Individual economies cannot run independent monetary policy (p. 11).

From these discussions, it is clear that the originators of the BSE/ELR programs are solidly in agreement that a floating exchange rate policy is necessary for implementation. The positive benefit of a floating exchange rate is further collaborated by Meulendyke who states "domestic policy actions are more independent than under relatively fixed exchange rates because policy is less constrained by official balance of payments settlements" (p. 209). In this scenario, monetary policy can be reinforced. She goes on to state:

For example, a tightening of monetary policy, ceteris paribus, tends to restrain
U.S. inflation and, over time, economic growth, driving up the dollar’s
exchange rate. A higher exchange rate, in turn, shifts trade from the United
States to other countries and contributes to slowing U.S. economic growth
(p. 209).

At this point, it might be easy to accept these conclusions as consistent and argue for a regime of flexible exchange rates. However, Davidson has provided excellent analysis in arguing for a return to a fixed exchange regime, also known as the Bancor plan. While Davidson does not address his arguments within the BSE/ELR framework, certain implications can be drawn from his work. Key to this work is the understanding that expectations in a non-ergodic international world are subject to rapid and often destabilizing effects on the balance of trade. In "International Money and the Real World," Davidson elaborates how the floating exchange rate contributes to destabilization. He describes these effects as follows:

If, however, a freely flexible (or even a crawling peg) exchange rate system is in
operation, then the elasticity of expectations is not constrained to values close to
Zero by the prevailing institutional structure of the foreign exchange market. Thus
a small decline in the spot exchange rate would not automatically induce an
expectation that this was a temporary deviation from a normal rate. Uncertainty
about future gains or losses will (by definition) necessarily be significantly greater
than in a fixed exchange rate system (p. 261).

The focus of Davidson's analysis is upon the amount of investment undertaken in an uncertain world. If greater volatility is evidence in the FX markets, investment decisions may be hindered or reduced.

This has important implications when considering a BSE/ELR type of program. Keynesian stimulus is designed to provide for increasing demand that, ceteris paribus, brings forth more investment. (It should be noted that this stimulus is not just the simple "printing of money" that is so often attributed to Keynesian policies.) While this demand certainly would result in a closed economy with increased internal investment, in an open economy this stimulus must be weighed carefully against balance of payment considerations. Mohsen Bahmani-Oskooee has indicated in a study of data for the period 1973-1988 that budget deficits raise import volumes and lower export volumes "in the short run as well as in the long run" (1991, p. 80). Since the Mosler-Mitchell-Forstater model relies on deficit monetary policy, it is evident that a serious balance of payments' problem could arise under the BSE/ELR proposal. The resulting deficit in the balance of payments can make investment unattractive even if the deficit country is running at full employment. This is due to the fact that a deficit balance of payment over time, ceteris paribus, will lower the foreign exchange value of the deficit nation and instigate uncertainty as to the future profitability of investments. As Davidson states in another paper, "Until we reform the world’s international payments system it will be impossible for any individual nation, except perhaps the United States, to undertake national macro policies to maintain high levels of aggregate demand internally without fear of a balance of payments constraint" (1998a, p. 7).

The important issue in this discussion is centered on investment incentives and uncertainty. In a expansionary policy like the BSE/ELR program, capital flows for investment will be impacted by the expectations of return and the needs for liquidity. If the expansion is viewed as inflationary, investment will be constrained as participants wait for more stabilization of price levels. This constraint on investment could have de-stabilizing affects due to the bottlenecks in production to meet the demand of the expanded work-force.

Another important consideration to this discussion is that Davidson attaches his fixed exchange regime to the existence of an international clearing mechanisms to provide for stability within the markets. The specifics of his recommendation are well known and need not be repeated here. However, it is important to this discussion to recognize that this "market-maker" is an important aspect to a fixed exchange regime.

One final background work that might be relevant to these discussions is provided by Sheila Dow. In her paper on monetary theory for an open economy, Dow examines monetary policy in both fixed and flexible exchange rate considerations. She provides an interesting conclusion that is stated as follows:

Whether exchange rates are more or less flexible determines primarily the
limitation put on the supply of finance during an expansion; the more fixed are
exchange rates, the greater the scope for capital inflows to continue to finance an
expansion. With fixed exchange rates, the responsiveness of supply to changes in
expected returns increases; with floating exchange rates, it is demand which
becomes more elastic. Since either of these increases the tendency towards
financial ease in an expansion and tightness in a contraction, the general statement
may be made that economic openness increases the scope for instability (1986,
p. 254).

The important fact that is drawn out by Dow’s paper is that instability can result under either a fixed or flexible regime as presently practiced.

Concluding Analysis

The goal of this discussion is to provide clarity in formulating a comprehensive policy program based on functional finance. One aspect of this program involves the implementation of a BSE/ELR or similar type of program. As Warren, Mitchell and Forstater have expounded, a BSE/ELR type of program can provide an avenue to ensure full employment and price stability. Equally, Davidson has also demonstrated in his works that unless an international regime of controls on the exchange market are instituted that de-stabilizing macro affects are likely to continue, thus hampering monetary policy from being pursued in exclusion to exchange factors. The major difference as revealed in the above discussion is on the issue of flexible or fixed exchange rate regimes.

Interesting enough, in all the discussion that Warren, Mitchell and Forstater have expressed, the fixed exchange rate policy is different from that advocated by Davidson. By this I mean they either involved pegs to the $US or involved the use of currency boards. In reaching their conclusions, these types of fixed exchange regimes have been shown to be detrimental to the economic situation. Thus, floating exchange rates should remain. However, it is clear from Davidson’s work that the fixed exchange rate regime he proposes solves many of the current deficiencies of the present system. Equally attractive is the fact that Davidsons’ program would eliminate a number of problems that have been associated with the flexible exchange rate and its hybrid fixed forms, such as the speculative motive. (Even today we have a commercial on TV that touts the ability to make $40,000 off a $10,000 investment in ONE MONTH in currency exchanges!) While Dow may be correct that under either regime, expansions and contractions will have de-stabilizing affects, it appears that greater stability can be ensured under a fixed exchange rate regime with its accompanying international market maker that Davidson proposes. In fact, it would seem that any implementation of a BSE/ELR program would work better if implemented with the Davidson program for international settlements. The Davidson proposal eliminates many of the problems that are voiced by the BSE/ELR proponents. Countries with persistent balance of trade deficits or surpluses would have a stabilizing institution to bring order to the market.

Having said this, let me restate my original desire for this discussion. It is to be hoped that this will inspire better clarity and discussion to the advantage of one FX regime over the other. My conclusions are preliminary and certainly not dogmatic at this point. Yet the overwhelming needs for international capital controls and the immediate need for providing for full-employment are one side of the same issue that must be addressed. This issue is in assuring that any full-employment policy will not have negative or destabilizing influences on other economic participants in a global environment. It is also important to recognize that capital flows under a stable state of expectations can provide much of the investment needed to finance the demand that full employment will produce.

Perhaps the esteemed words of Abba Lerner are in order at this point:

The central idea is that government fiscal policy, its spending and taxing,
its borrowing and repayment of loans, its issue of new money and its
withdrawal of money, shall all be undertaken with an eye only to the
results of these actions on the economy and not to any established
traditional doctrine about what is sound or unsound (p. 39).

Comments and discussion encouraged.
