covered interest rate arbitrage in the interwar period and the keynes einzig conjecture keynes 1923 conjectured that deviations from covered interest rate parity would not be arbitraged unless a profit of at least a half of one percent on an annualized basis was available and that larger deviations would still be moderately persistent because of less than perfect elasticity of supply of arbitrage funds this two part conjecture was given further emphasis by other writers on this period notably einzig 1937 we apply nonlinear econometric techniques to a previously unexploited weekly data base for the 1920s london and new york markets and find strong support for the conjecture

volume liquidity and liquidity risk abstract many classes of microstructure models as well as intuition suggest that it should be easier to trade when markets are more active in the data however volume and liquidity seem unrelated over time this paper offers an explanation for this fact based on a simple frictionless model in which liquidity reflects the average risk bearing capacity of the economy and volume reflects the changing contribution of individuals to that average volume and liquidity are unrelated in the model but volume is positively related to the variance of liquidity or liquidity risk empirical evidence from the u s government bond and stock markets supports this new prediction

the political economy of sugar legislation the findings of this paper are a rather straightforward account of the political economy of senatorial voting on the sugar program in the spirit of stigler and peltzman s accounts of interest group activity voting on sugar is indeed related to the concentration of economic interests in the senators states states with high concentrations of sugar growers and processing tend to vote for the program those with high concentration of users tend to vote against it the emergence of corn syrup as a sugar substitute and its subsequent interests in the program further supports this perspective these concentrated interests are associated with conditions ripe for overcoming the collective action problem and we infer use their organizations to influence senatorial behavior the political variables suggest countervailing forces which can be interpreted at least in part as further examples of organized here politically organized influences on the interests of senators thus while the model is one of opposing interests those of producers and users tend to influence different senators the major group interest trade off then is between the pull of organized interests in the constituency with that of party organization at the national or national institutional level at least for those for whom the pull is in opposite directions

funding liquidity and equity liquidity in the subprime crisis period evidence from the etf market using index and financial exchange traded funds etfs this study explores the relation between funding liquidity and equity liquidity during the subprime crisis period our empirical results show that a higher degree of funding illiquidity leads to an increase in bid ask spread and a reduction in both market depth and net buying imbalance such findings indicate that an increase in funding liquidity can improve equity liquidity with a stronger effect for the financial etfs than for the index etfs our study provides a better overall understanding of the effect of the liquidity supplier funding constraint during the subprime crisis period

covered interest arbitrage and market turbulence the covered interest parity theorem states that the covered interest differential between two similar assets denominated in different currencies should be zero this paper utilizes high quality data recorded by the dealers at the bank of england to test covered interest parity during certain historical periods in which there is known to have been turbulence as well as during a relatively calm control period the data is high frequency and allowance is made for the bid offer spread brokerage costs and other considerations the results have three main implications firstly profitable arbitrage opportunities do occasionally occur and sometimes persist during turbulent periods secondly the degree of efficiency of the relevant markets appears to have increased over time thirdly there appears to be a maturity effect whereby the existence and size of profitable arbitrage opportunities appear to be positive functions of the length of maturity a rationalization of this phenomenon is offered in terms of the existence of credit limits copyright 1989 by royal economic society

intra day arbitrage opportunities in foreign exchange and eurocurrency markets we have two primary objectives in this study first we examine the frequency of attaining simultaneous equilibrium on spot and forward foreign exchange markets and on domestic and foreign securities markets second we measure the profitability of covered interest arbitrage and one way arbitrage our empirical analysis has been conducted using real time quotations the empirical results indicate that a the markets are efficient in the sense that profit opportunities from traditional covered interest arbitrage are rarely available and b the frequency of attaining simultaneous market equilibrium is surprisingly low thus opening the door for one way arbitrage the role of transaction costs in explaining the deviation of the actual forward price from the interest parity forward price has been studied extensively based on covered interest arbitrage frenkel and levich 1975 1977 have shown that the interest parity line is bound by a neutral band defined as

preferred habitat for liquidity in international short term interest rates abstract risk shifting window dressing and a preferred habitat for liquidity have been offered as possible explanations as to why us money market rates are higher before the year end than afterwards the two hypotheses differ in the timing of the rate decline at the year end and the evidence on the timing of the decline supports the preferred habitat hypothesis in us money markets this paper extends this line of research to the behavior of international short term interest rates at year ends and quarter ends using london interbank offer rates libor for 11 different currencies the results suggest that the behavior of libor for five currencies the us dollar euro japanese yen swiss franc and german mark is consistent with year end or quarter end preferred habitats for liquidity other currencies do not demonstrate consistently distinct patterns in turn of the year and turn of the quarter yields none of the results provides any support for risk shifting window dressing

covered interest arbitrage profits the role of liquidity and credit risk we study the profitability of covered interest parity cip arbitrage violations and their relationship with market liquidity and credit risk using a novel and unique dataset of tick by tick firm quotes for all financial instruments involved in the arbitrage strategy the empirical analysis shows that positive cip arbitrage deviations include a compensation for liquidity and credit risk once these risk premia are taken into account small arbitrage profits only accrue to traders who are able to negotiate low trading costs the results are robust to stale pricing and the nonsynchronous trading occurring in the markets involved in the arbitrage strategy

re election incentives and deforestation cycles in the brazilian amazon abstract despite expansive research on amazonian deforestation and its drivers the role of local politics is not well understood using a panel data set that combines municipal level deforestation and election data from 2002 to 2012 i estimate the effect of an incumbent mayor running for re election on deforestation rates in election periods i find that deforestation rates increase 8 10 in election years when an incumbent mayor runs for re election an amount equivalent to four percent of the total forest lost since the 2004 elections electoral deforestation cycles do not appear to be driven by changes in agricultural policy implementation and activity but are linked to corruption and campaign finance suggesting that weak institutional constraints facilitate electoral manipulation of forest resources this phenomenon is not likely limited to amazonian forests re election incentives could very well lead to misallocation of other natural resources in alternate geographies

a stochastic dominance analysis of yen carry trades abstract yen carry trades have made headline news for over a decade we examine the profitability of such trades for the period 2001 2009 yen carry trades generated high mean returns and sharpe ratios prior to the recent financial crisis they continued to outperform major stock markets for the full sample period given the non normality of carry trade returns we apply non parametric tests based on stochastic dominance sd to evaluate whether the high returns of yen carry trades are compatible with risk as reflected in returns on us and global stock market indices we apply a general test for sd developed recently by linton maasoumi and whang 2005 to six currencies as well as portfolios of these currencies for a large class of risk averse investors profits from yen carry trades cannot be attributed to risks

information and index arbitrage a random cash futures basis is derived in a dynamic multimarket learning game with sequential information shocks and strategic arbitrageurs who trade to exploit gaps in the basis statistical properties of the authors theoretical basis are derived both with and without index arbitrage the authors find that basis volatility a measure of intermarket mispricing may initially increase even as individual prices become more precise and that arbitrage reduces basis volatility the model is also used to analyze regulatory issues such as the possible impact of circuit breakers on the quality of the trading process copyright 1994 by university of chicago press

measuring true stock index value in the presence of infrequent trading based on the beveridge nelson 1981 decomposition of an arima process i present a measure of true stock index value that is not directly observable due to infrequent trading of stocks the technique is illustrated with daily observations of the russell 2000 index this new measure might well prove useful in studies of lead lag relationships between index derivatives and spot market and futures basis measurements

the microeconomics of market making this paper examines the influence of risk aversion on the pricing policies of a market maker for securities it is shown that a market maker s bid ask spread can be decomposed into a portion for the known limit orders a risk neutral adjustment for expected market orders and a risk adjustment for market order and inventory value uncertainty it is dem onstrated that a risk averse market maker may set a smaller spread than a risk neutral specialist finally this paper demonstrates the pervasive role of inventory in affecting both the placement and size ofthe spread

do liquidity measures measure liquidity abstract given the key role of liquidity in finance research identifying high quality proxies based on daily as opposed to intraday data would permit liquidity to be studied over relatively long timeframes and across many countries using new measures and widely employed measures in the literature we run horseraces of annual and monthly estimates of each measure against liquidity benchmarks our benchmarks are effective spread realized spread and price impact based on both trade and quote taq and rule 605 data we find that the new effective realized spread measures win the majority of horseraces while the amihud 2002 illiquidity and stock returns cross section and time series effects journal of financial markets 5 31 56 measure does well measuring price impact

when and how us dollar shortages evolved into the full crisis evidence from the cross currency swap market abstract this paper investigates when and how the us dollar shortages evolved into the full crisis in the cross currency swap market between major european currencies and the us dollar during the turmoil of 2007 2009 using the dynamic factor model with regime switching coefficients of each swap price with respect to the latent common factor the 1 year market entered the high crisis regime soon after the onset of the subprime problem in august 2007 the 10 year market entered that regime following the collapse of bear sterns in mid march 2008 financial credit spreads have significant predictive power for switches between high and low regimes

does the law of one price hold in international financial markets evidence from tick data abstract this paper investigates the validity of the law of one price lop in international financial markets by examining the frequency size and duration of inter market price differentials for borrowing and lending services one way arbitrage using a unique data set for three major capital and foreign exchange markets that covers a period of more than seven months at tick frequency we find that the lop holds on average but numerous economically significant violations of the lop arise the duration of these violations is high enough to make it worthwhile searching for one way arbitrage opportunities in order to minimize borrowing costs and or maximize earnings on given funds we also document that such opportunities decline with the pace of the market and increase with market volatility

margin based asset pricing and deviations from the law of one price in a model with heterogeneous risk aversion agents facing margin constraints we show how securities required returns increase in both their betas and their margin requirements negative shocks to fundamentals make margin constraints bind lowering risk free rates and raising sharpe ratios of risky securities especially for high margin securities such a funding liquidity crisis gives rise to bases that is price gaps between securities with identical cash flows but different margins in the time series bases depend on the shadow cost of capital which can be captured through the interest rate spread between collateralized and uncollateralized loans and in the cross section they depend on relative margins we test the model empirically using the credit default swap bond bases and other deviations from the law of one price and use it to evaluate central banks lending facilities jel g01 g12 g13 e44 e50 the paramount role of funding constraints becomes particularly salient during liquidity crises with the one that started in 2007 being an excellent case in point banks unable to fund their operations closed down and the funding problems spread to other investors such as hedge funds that relied on bank funding therefore traditional liquidity providers became forced sellers interest rate spreads increased dramatically treasury rates dropped sharply and central banks stretched their balance sheets to facilitate funding these funding problems had significant asset pricing effects the most extreme example being the failure of the law of one price loop securities with nearly

liquidity and the law of one price the case of the futures cash basis deviations from no arbitrage relations should be related to market liquidity because liquidity facilitates arbitrage at the same time a wide futures cash basis may trigger arbitrage trades and in turn affect liquidity we test these ideas by studying the dynamic relation between stock market liquidity and the index futures basis there is evidence of two way granger causality between the short term absolute basis and liquidity and liquidity granger causes longer term absolute bases shocks to the absolute basis predict future stock market liquidity the evidence suggests that liquidity enhances the efficiency of the futures cash pricing system copyright 2007 by the american finance association

monetary policy and covered interest parity in the post gfc period evidence from the australian dollar and the nz dollar abstract after the global financial crisis gfc most major currencies had higher interest rates than the us dollar on forward contract because of increased demand for the us dollar as international liquidity however unlike the other major currencies the australian dollar and the nz dollar had lower interest rates than the us dollar on forward contract in the post gfc period the purpose of this paper is to explore why this happened through estimating the covered interest parity cip condition in the analysis we focus on a unique feature of australia and new zealand where short term interest rates remained significantly positive even after the gfc the paper first constructs a theoretical model where increased liquidity risk causes deviations from the cip condition it then tests this theoretical implication by using daily data of six major currencies we find that both money market risk measures and policy rates had significant effects on the cip deviations the result implies that unique monetary policy feature in australia and new zealand made deviations from the cip condition distinct on the forward contract
