long live the doge death as a term limit on venetian chief executives can an electorate use the projected life expectancy of a lifetime appointed chief executive to enforce binding informal term limits informal term limits based on the life expectancy of a chief executive candidate at election would enable an electorate to exercise discretion in adjusting tenure lengths to minimize expected turnover and tenure length costs while also providing a strictly binding term limit death we provide a detailed historical case study of venice from 1172 to 1797 when the ruling patricians utilized informal term limits on their chief executive the doge relying on the projected life expectancy of ducal candidates

trading volume and information revelation in stock markets i consider a market microstructure model in which the rates of public and private informa tion arrival are probabilistic the latter depends on the availability of private information that is stochastically changing over time in equilibrium traders estimate the availability of private information using past periods trading volume and use this information to adjust their strategies the time series properties include contemporaneous correlation between price variability and volume and autocorrelation in price variability similar to garch the model explains why trading volume contains useful information for predicting volatil ity and provides predictions on the limit and market order placement strategies of traders

financial intermediary coalitions abstract in this article an environment in which the investment opportunities of agents are private information is studied and it is shown that financial intermediaries arise endogenously within that environment it is established that financial intermediaries are part of an efficient arrangement in the sense that they are needed to support the authors private information core allocations these intermediaries which are coalitions of agents exhibit the following characteristics in equilibrium they borrow from and lend to large groups of agents they produce information about investment projects and they issue claims that have different state contingent payoffs than claims issued by ultimate borrowers

weather and intraday patterns in stock returns and trading activity abstract we examine the relation between weather in new york city and intraday returns and trading patterns of nyse stocks while stock returns are found to be generally lower on cloudier days cloud cover has a significant influence on stock returns only at the market open there are significantly more seller initiated trades when there is more cloud cover at the market open which is consistent with the return results cloudy skies are associated with higher volatility and less market depth over the entire trading day finally cloud cover is not significantly correlated with spread measures and turnover ratios the findings overall suggest that weather has a significant influence on investors intraday trading behavior

determinants of bank growth choice abstract we study the determinants of bank growth in a two stage logistic regression model we first compare banks that branch bank acquire or product expand with banks that do not grow externally banks that are federally chartered in states with higher income growth and with higher labor prices are less likely to grow externally larger banks are more likely to grow externally in the second stage we study determinants of growth activity for banks that expand products branch or acquire other banks depending on the time period bank structure regulatory environment performance and balance sheet characteristics determine bank growth choices

disagreement and asset prices abstract how do differences of opinion affect asset prices do investors earn a risk premium when disagreement arises in the market despite their fundamental importance these questions are among the most controversial issues in finance in this paper we use a novel data set that allows us to directly measure the level of disagreement among wall street mortgage dealers about prepayment speeds we examine how disagreement evolves over time and study its effects on expected returns return volatility and trading volume in the mortgage backed security market we find that increased disagreement is associated with higher expected returns higher return volatility and larger trading volume these results imply that there is a positive risk premium for disagreement in asset prices we also show that volatility in and of itself does not lead to higher trading volume instead only when disagreement arises in the market is higher uncertainty associated with more trading finally we are able to distinguish empirically between two competing hypotheses regarding how information in markets gets incorporated into asset prices we find that sophisticated investors appear to update their beliefs through a rational expectations mechanism when disagreement arises

trading halts and market activity an analysis of volume at the open and the close this paper analyzes how the daily opening and closing of financial markets affect trading volume we model the desire to trade at the beginning and end of the day as a function of overnight return volatility nyse data from 1933 88 indicate that closing volume is positively related to expected overnight volatility while volume at the open is positively related to both expected and unexpected volatility from the previous night we interpret the symmetric response of trading at the open and the close to expected volatility as being due to investor heterogeneities in the ability to bear risk when the market is closed this desire of investors to trade prior to market closings indicates a cost of mandating marketwide circuit breakers

a model of the financial firm with imperfect asset and deposit elasticities abstract the paper develops an intertemporal model to estimate the production technology of financial firms such as banks price taking is testable in each separate market for assets and liabilities and competitive price taking is a nested special case such tests are applied both to outputs and inputs empirical results for a sample of banks in new york and new jersey indicate that price taking applies only in markets for labor and time deposits in markets for loans demand deposits cash and materials the price taking hypothesis is not accepted

effects of financial innovations on market volatility when beliefs are heterogeneous abstract consider a model with two logarithmic utility maximizer agents that observe aggregate consumption but disagree about its expected rate of change markets are incomplete we first show that volatility of the interest rate in an economy with additional information is higher in a complete markets economy with no additional information there are two differences in volatility with the previous the first one due to the increase in volatility of the wealth share of the individuals is always positive the second difference is the change in covariance between the components of the interest rate volatility and can be positive or negative

the contribution of product mix versus efficiency and technical change in us banking abstract similar to a du pont analysis this paper divides the changes in returns on assets of us commercial banks for the period from 2000 to 2005 into conventional measures of bank performance the contribution of product mix is significant and offsets losses from technical change and operating efficiency banks respond to changes in the business environment by switching towards more lucrative traditional and nontraditional products large banks are found to benefit more than community banks from the switch to an optimal output portfolio mix including new products spawned by recent financial innovations and deregulation

how do banks respond to shocks a dynamic model of deposit taking institutions abstract this paper proposes a dynamic model of the optimal choices of a bank that benefits from market power and takes into account the impact of the deposit generation process interbank lending borrowing emerges as a buffer that assists the bank in smoothing intertemporal adjustments in interdependent loan and deposit choices the bank smooths the impact of interest rates shocks on its customers to minimize the adjustments over time of the stocks of deposits and loans it does not however provide insurance against negative shocks of real origin that increase its expected default costs the predictions of the model help to shed light on the available empirical evidence and to analyze some recent developments of the banking industry

informational linkages across trading regions evidence from foreign exchange markets abstract using a new high frequency data set from electronic broking services ebs this paper examines informational linkages in the euro dollar and dollar yen exchange rates across five trading regions asia pacific the asia europe overlap europe the europe america overlap and america information is proxied by exchange rate return direction of return volatility trading activity and order flow we find that informational linkages are statistically significant at both own region and inter region levels but own region spillovers dominate in economic significance especially for volatility and trading activity in addition order flow spillovers from the europe america overlap trading region are the most important source of spillovers to other trading regions for both currency pairs

an empirical evaluation of the overconfidence hypothesis abstract recently several behavioral finance models based on the overconfidence hypothesis have been proposed to explain anomalous findings including a short term continuation momentum and a long term reversal in stock returns we characterize the overconfidence hypothesis by the following four testable implications first if investors are overconfident they overreact to private information and underreact to public information second market gains make overconfident investors trade more aggressively in subsequent periods third excessive trading of overconfident investors in securities markets contributes to the observed excessive volatility fourth overconfident investors underestimate risk and trade more in riskier securities to document the presence of overconfidence in financial markets we empirically evaluate these four hypotheses using aggregate data overall we find empirical evidence in support of the four hypotheses

an empirical examination of information differences of opinion and trading activity abstract we investigate the relations between trading volumes and our proxies for information flows and divergences in opinions we view s p 500 index futures open interest as a useful proxy for divergences of traders opinions and find that volumes are higher on days when open interest increases than on days with declines volume in individual equities is more closely related to firm specific information flows while equity basket volume is more closely associated with market information this differential impact is greatest for small capitalization stocks where market wide news has no explanatory power

divergence of opinion in complete markets a note we consider an arrow debreu model with agents who have different subjective probabilities in general asset prices will depend only on aggregate consumption and the distribution of subjective probabilities in each state of nature if all agents have identical preferences then an asset with more dispersed subjective probabilities will have a lower price than an asset with less dispersed subjective probabilities if risk aversion does not decline too rapidly it seems that this condition is likely to be met in practice so that increased dispersion of beliefs will generally be associated with reduced asset prices in a given arrow debreu equilibrium there have been several recent investigations concerning the effect of heterogeneous probability beliefs on asset prices most of these investigations have taken place in the context of capm like mean variance models see for example lintner 5 miller 7 williams 10 jarrow 4 and mayshar 6 comparatively little has been done in the analysis of differences of opinion in an arrow debreu contingent claims context rubinstein 8 breeden and litzenberger 2 and breeden 1 have presented nice analyses of asset price determination in an arrow debreu model but most of their results have assumed commonly held probability beliefs in this paper we analyze the impact of divergence of opinion on asset prices in an arrow debreu economy the results serve to generalize the findings of rubinstein and breeden litzenberger to the case of different probability beliefs among the results we establish are 1 in equilibrium asset prices depend only on aggregate consumption and the distribution of subjective probability beliefs 2 asset values are an increasing function of any one individual s probability beliefs 3 an increase in the spread of the probability beliefs of investors may increase or decrease equilibrium asset values depending on the value of a parameter of the utility function however the most likely effect is to decrease the asset values these results are especially interesting in light of the recent empirical work of cragg and malkiel 3 they studied the relationship between ex post return and various measures of risk for common stocks and found that the measure of risk that performed best in their analysis was a measure of divergence of opinion

bank commercial loan markets and the role of market structure evidence from surveys of commercial lending abstract this paper seeks to test two tenets that underlie the current practice of antitrust analysis in banking the first is the view that bank commercial loan markets are local in nature and the second is the view that banks in more concentrated markets are more likely to engage in some form of noncompetitive behavior tests of both of these tenets are conducted using an extensive set of loan specific survey information not previously employed to address these issues results consistent with the existence of local banking markets and the dominance of competitive differences as an explanation for observed differences in loan rates are found

the dominance of inefficiencies over scale and product mix economies in banking abstract this study measures and analyzes inefficiencies for all u s banks in 1984 inefficiencies are measured relative to a thick frontier cost function and are found to dominate measured scale and product mix economies most inefficiencies are operational in nature involving the overuse of physical inputs rather than financial involving overpayment of interest also technical inefficiencies proportionate overuse of all inputs dominate allocative inefficiencies improper mix of inputs these results suggest that competitive pressures in banking from deregulation will be focused primarily on banks that do not control costs rather than on those of a particular size or product mix

disagreement and learning dynamic patterns of trade we study volume dynamics when there are disagreements among investors for that purpose we develop a dynamic model in which differences in the interpretation of public information lead to trade we obtain a simple linear equilibrium in closed form in which risk averse agents take into account future trading opportunities when solving for their optimal portfolio allocation using this framework we then study what restrictions on the disagreement process are needed to generate empirically observed patterns in volume and prices we show that having infrequent but major disagreements leads to autocorrelation in volume and correlation between volume and absolute price changes when agents disagree on past news but agree on the interpretation of current news there is learning and the convergence of agents opinions leads to trade

the role of fixed costs and cost complementarities in determining scope economies and the cost of narrow banking proposals narrow banking proposals would separate insured deposits from most types of bank lending using data from large u s banks the authors examine the extent to which narrow banking proposals are likely to result in increased production costs production costs will rise for nonjoint provision of deposit and loan services if there are cost complementarities in producing the two outputs jointly or if joint production enables banks to spread their fixed costs more effectively unlike standard cost function approaches the authors methods allow them to estimate the fixed cost and cost complementarity effects separately they find the net production cost consequences of narrow banking to be negligible copyright 1993 by university of chicago press

the administrative foundations of self enforcing constitutions current theories of the rule of law argue that public officials respect rights if the citizens are coordinated on an equilibrium in which they collectively resist abuse constitutional rules are means to coordinate on this equilibrium in past and present states however constitutional rules often have no effect on the rule of law this paper suggests an alternative view of the origin and development of the rule of law instead of considering constitutional rules as coordination devices for citizens at large history suggests considering them as manifestations of equilibria with rulers constrained by administrators required to implement policy analysis of the administrative foundations of self enforcing constitutions may be the key to a theory and policy that would foster the rule of law in developing countries and those in transition in particular constitutional reforms might benefit from focusing on altering the equilibrium distribution of administrative capacity and power providing incentives to the administratively powerful to check predation by each other and the central authorities and to align administrators interests with social welfare

financial distress drivers in brazilian banks a dynamic slacks approach abstract this study applies the dynamic slacks based model dsbm developed by tone and tsutsui 2010 in order to assess the evolution of input saving output increasing potentials in major brazilian banks from 1996 to 2011 we propose that these potentials or slacks can be used as proxies for an eventual financial distress situation in the future the main research objective is to determine whether or not different characteristics of bank type related to ownership size and merger and acquisition processes are significantly related to inefficiency levels and by extension to an eventual financial distress situation since higher inefficiency levels also imply lower input saving output decreasing potentials based on a balanced panel model secondary data from economatica were collected and analyzed results indicate higher inefficiency levels and slacks in small public and national banks policy implications are also addressed

market sidedness insights into motives for trade initiation we infer motives for trade initiation from market sidedness we define trading as more two sided one sided if the correlation between the number of buyer and seller initiated trades increases decreases and assess changes in sidedness relative to a control sample around events that identify trade initiators consistent with asymmetric information trading is more one sided before merger news consistent with belief heterogeneity trading is more two sided before earnings and macro announcements with greater dispersion in analyst forecasts and after news with larger announcement surprises we examine the codeterminacy of sidedness bid ask spread volatility number of trades and order imbalance

learning from prices and the dispersion in beliefs i study whether investors use an asset s price to update their beliefs about its payos i show that in a dynamic economy the relationship between the dispersion in investor beliefs and returnvolume characteristics can be used to empirically answer this question when investors have rational expectations re and condition on the price i show that belief dispersion is positively related to expected returns return volatility and correlation between volume and absolute returns but negatively related to return autocorrelation when investors do not use the price as in a dierence of opinions do model these relationships are reversed i test these predictions using the crosssection of returns volume and analyst forecast dispersion over dierent horizons the results are consistent with the re model at quarterly and longer horizons but reject both models at the monthly horizon i show that a hybrid model with some do investors and some re investors can match the short horizon evidence the empirical results are consistent with the idea that while some investors do not use the price in the short run they increase their conditioning on the price over time

measurement effects and the variance of returns after stock splits and stock dividends this article examines the relation between two factors affecting stock returns the bid ask spread and price discreteness and the increase in return variance after ex dates of stock splits and stock dividends controlling for these effects the variance of daily returns still increases significantly the variance of weekly returns also increases significantly and the variance of returns for a control sample of nonsplitting firms shows no significant increase variance ratio tests show that bid ask errors are small for these stocks and therefore cannot explain the large increase in variance spreads and price discreteness do not explain increased variance after stock distributions article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

public goods institutions human capital and growth evidence from german history what are the origins and consequences of the state as a provider of public goods we study public goods provision established through new laws in german cities during the 1500s cities that adopted the laws subsequently began to differentially produce and attract human capital and to grow faster legal change occurred where ideological competition introduced by the protestant reformation interacted with local politics we study plagues that shifted local politics in a narrow period as sources of exogenous variation in public goods institutions and find support for a causal interpretation of the relationship between legal change human capital and growth

what does it take for a roving bandit settle down theory and an illustrative history of the visigoths a roving bandit provides exclusive rivalrous collective goods to members of its in group a stationary bandit further provides inclusive non rivalrous public collective goods to the out group the inclusive goods are an input to the production of the exclusive goods enjoyed by the in group as such the transition from roving to stationary bandit is likely to involve the redefinition of the in group its collective interest and the type of goods that it provides to illustrate these points i employ a case study of the roving visigothic confederacy as it evolved during the fourth and fifth centuries towards the stationary visigothic kingdom the illustration provides insights into why competition amongst roving bandits does not always or often lead to the emergence of a non predatory state

financial intermediation and delegated monitoring this paper develops a theory of financial intermediation based on minimizing the cost of monitoring information which is useful for resolving incentive problems between borrowers and lenders it presents a characterization of the costs of providing incentives for delegated monitoring by a financial intermediary diversification within an intermediary serves to reduce these costs even in a risk neutral economy the paper presents some more general analysis of the effect of diversification on resolving incentive problems in the environment assumed in the model debt contracts with costly bankruptcy are shown to be optimal the analysis has implications for the portfolio structure and capital structure of intermediaries

how do diversity of opinion and information asymmetry affect acquirer returns we examine the theoretical predictions that link acquirer returns to diversity of opinion and information asymmetry theory suggests that acquirer abnormal returns should be negatively related to information asymmetry and diversity of opinion proxies for equity offers but not cash offers we find that this is the case and that more strikingly there is no difference in abnormal returns between cash offers for public firms equity offers for public firms and equity offers for private firms after controlling for one of these proxies idiosyncratic volatility jel g31 g32 g34 this article examines whether variables suggested by diversity of opinion models and information asymmetry models are helpful in understanding the cross sectional variation in acquirer announcement returns using a sample of pure equity offers and pure cash offers for public and private firmsfrom1980to2002 wedocumentthatthesevariables theuncertainty proxies explain a significant fraction of the cross sectional variation in acquirer announcement returns perhaps most strikingly after controlling for the uncertainty proxies there is no difference in abnormal returns between cash offers for public firms equity offers for public firms and equity offers for private firms using two proxies for diversity of opinion employed previously in the literature the standard deviation of analyst forecasts and breadth of ownership we show that bidder abnormal returns for acquisitions of

inferring market power from time series data abstract using bank specific data on deposit rates this paper tests for the existence of market power in banking by means of time series estimations a test is developed that can reject perfect competition on the basis of the observed relationship over time between deposit rates and security rates adjusted for operating costs the analysis also examines whether pricing behavior differs across markets and banking products in a manner consistent with hypothesized differences price taking behavior is rejected for the vast majority of banks for the deposit category that one would expect to be more geographically limited greater market power is found to be exercised by banks located in more concentrated markets

banks responses to deregulation profits technology and efficiency the deregulation of interest rates in the early 1980s raised bank funding costs and lowered profits in response banks raised fees for deposit services reduced branch operating costs and shifted to higher earning assets rates of return did not regain their prederegulation levels until the early 1990s our goal is to decompose the change in bank profits following deregulation into i intemal bank initiated adjustments to the new regulatory structure and ii external contemporaneous changes in banks business environment this decomposition will depend in part on the assumed competitive structure of the banking industry with perfect competition output and input prices are part of the external environment and banks responses are limited to changes in output and input quantities an alternative approach assumes imperfect competition where banks have some control over output prices deposit fees minimum balance requirements and interest rates on certain loans and output quantities and input prices comprise the external environment the altemative model is supported by the data using this model large banks but not smaller banks are found to have relied primarily on changing output prices and input use to mitigate and reverse the negative effects of deregulation on profits the adjustment to deregulation was essentially complete after four years following this additional changes in bank profitability during the late 1980s were primarily due to changes in banks business environment

stock prices and volume the authors undertake a comprehensive investigation of price and volume co movement using daily new york stock exchange data from 1928 to 1987 they adjust the data to take into account well known calendar effects and long run trends to describe the process they use a seminonparametric estimate of the joint density of current price change and volume conditional on past price changes and volume four empirical regularities are found 1 positive correlation between conditional volatility and volume 2 large price movements are followed by high volume 3 conditioning on lagged volume substantially attenuates the leverage effect and 4 after conditioning on lagged volume there is a positive risk return relation article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

short sales constraints and price discovery evidence from the hong kong market short sales practices in the hong kong stock market are unique in that only stocks on a list of designated securities can be sold short by analyzing the price effects following the addition of individual stocks to the list we find that short sales constraints tend to cause stock overvaluation and that the overvaluation effect is more dramatic for individual stocks for which wider dispersion of investor opinions exists these findings are consistent with miller s 1977 intuition and other optimism models we also document higher volatility and less positive skewness of individual stock returns when short sales are allowed the question of how short sales impact capital markets is highly controversial with short sale regulations varying widely across countries and capital markets 1 although short selling has been carried out for years in major financial markets around the world its effects on market efficiency especially on pricing efficiency remain of interest to financial researchers miller 1977 theorizes that in the presence of short sales constraints security prices tend to reflect a more optimistic valuation than the average opinion of potential investors and thus tend to be upward biased this overvaluation argument is based on two conditions 1 a security s short sales are either prohibited or costly and 2 investors have heterogeneous beliefs or information about the security s value the underlying intuition is quite straightforward pessimistic investors are forced to sit out of the market when short sales are not available and thus some negative information is not reflected in prices enabling enthusiastic buyers to bid prices above the level that average investors perceive as fair this argument has significant implications for market efficiency theories since one of the major functions of capital markets is price discovery indeed an efficient market should be a market in which prices always

strategic trading behavior and price distortion in a manipulated market anatomy of a squeeze abstract this paper investigates an attempted delivery squeeze in a bond futures contract traded in london using cash and futures trades of dealers and customers we analyze their strategic trading behavior price distortion and learning in a market manipulation setting we argue that marked differences in settlement failure penalties in the cash and futures markets create conditions that favor squeezes we recommend that regulators require special flagging of forward term repurchase agreements on the key deliverables that span futures contract maturity dates and that exchanges mark to market their contract specifications more frequently or consider a cash settled contract on a basket of bonds

differential interpretation of public signals and trade in speculative markets most models of trade in speculative markets assume that agents interpret public information identically we provide empirical evidence on the relation between the volume of trade and stock returns around public announcements and we argue that the evidence is inconsistent with this assumption we then develop a model of trade around public announcements that incorporates differential interpretations and is consistent with the observed volume return relation then we test the standard model of belief revision underlying most models of trade using stock brokerage research analysts earnings forecasts the hypthesis of identical interpretations seems inconsistent with the forecast revisions in these data

do consumers pay for one stop banking evidence from an alternative revenue function abstract in providing financial services jointly banks may reduce costs due to complementarities in production cost economies of scope or raise revenues from complementarities in consumption revenue economies of scope cost economies of scope between bank deposits and loans have been found to be small revenue economies of scope are investigated here for the first time and found to be insignificant over 1978 1990 for both small and large banks and for those on or off the revenue efficient frontier the lack of complementarities between deposits and loans where benefits are most likely to occur suggests that claims of important synergies from an expansion of banking powers be taken with caution

takeovers and divergence of investor opinion we test several hypotheses on how takeover premium is related to investors divergence of opinion on a target s equity value we show that the total takeover premium the pre announcement target stock price run up and the post announcement stock price markup are all higher when investors have higher divergence of opinion we obtain identical results with higher market level investor sentiment when divergence of opinion is higher a firm is less likely to be a takeover target although takeover synergy in successful takeovers is higher our results suggest that takeovers may play a role in explaining high contemporaneous stock prices in the presence of high divergence of investor opinion the author 2011 published by oxford university press on behalf of the society for financial studies all rights reserved for permissions please e mail journals permissions oup com oxford university press

history lessons institutions factor endowments and paths of development in the new world the explanations offered for the contrasting records of long run growth and development among the societies of north and south america most often focus on institutions the traditional explanations for the sources of these differences in institutions typically highlight the significance of national heritage or religion we in contrast argue that a hemispheric perspective across the wide range of colonies established in the new world by the europeans suggests that although there were many influences factor endowments or initial conditions had profound and enduring effects on the long run paths of institutional and economic development followed by the respective economies

an examination of cost subadditivity and multiproduct production in large u s banks this paper examines the subadditivity of costs for a sample of the largest commercial banks in the u s we introduce into the bank production literature the grid approach developed by evans and heckman 1984 we estimate two models of the bank cost function one where deposits are treated as outputs while in the other deposits are treated as inputs the models are estimated using the commonly used translog and the more flexible miniflex laurent viewed narrowly the findings imply that cost complementarities are not the raison d etre for multiproduct production in the largest commercial banks subadditive costs however are sufficient but not necessary for multiproduct production it is quite possible for multiproduct production to be optimal when output are produced independently levy and haber 1986 and teece 1980 1982 it is only required that inputs be shareable as opposed to joint copyright 1990 by ohio state university press

market created risk we develop a multiperiod rational expectations model of securities market equilibrium in which equilibrium prices may move between periods even though it is common knowledge that no new information has arrived about ultimate security payoffs this happens because investors know they have imperfect information about the endowments of other investors and this knowledge affects their probability beliefs about the prices that will prevail at the intermediate trading date these beliefs are reflected in the equilibrium at the initial trading date when investors focus on the probabilities of intermediate capital gains and losses rather than ultimate payoffs virtually all models of the pricing of securities employ some notion of market equilibrium so for prices to fluctuate something in the equilibrium must change since equilibrium in an informationally efficient market implies that market clearing prices reflect all available information about future securities payoffs it seems to be frequently assumed that observed jumps in prices ought under the efficient market hypothesis to reflect the arrival of new information about future cash payoffs to securities the major theme of this paper is to examine a multiperiod model of securities market equilibrium in which equilibrium prices may change sharply between periods even if it is common knowledge that no new information about ultimate payoffs has arrived and all investors are rational and make full use of all available information in our model the new information that leads to a price change is information about how much of the known total supply of risky securities is held by investors of different preferences for this model to produce intertemporal price fluctuation in equilibrium two phenomena must occur firstly the initially unknown composition of the market must not be revealed by equilibrium prices at the initial trading date secondly despite this the true composition of the market must at least partially determine prices at a later trading date they key to both these phenomena lies in the difference in investor behavior when they anticipate revising their current portfolio holdings in response to future price changes as compared to when they choose portfolios on the basis of receiving the ultimate cash payoffs to the securities they buy in practice few investors anticipating holding financial securities to their eventual liquidation by the issuer short term debt or debt close to maturity would be the major exception few equity securities relative to the total supply

two trees with heterogeneous beliefs spillover effect of disagreement in a model where investors disagree about the fundamentals of two stocks the state price density depends on investor disagreements for both stocks especially the larger stock this implies that disagreement among investors in a large firm has a spillover effect on the pricing of other stocks owned by these investors the pricing effects of investor disagreements crucially depend on the average belief biases empirical findings support the novel model prediction of a disagreement spillover effect and help reconcile some mixed evidence in the literature

belief dispersion in the stock market we develop a dynamic model of belief dispersion with a continuum of investors differing in beliefs the model is tractable and qualitatively matches many of the empirical regularities in a stock price its mean return volatility and trading volume we find that the stock price is convex in cash flow news and increases in belief dispersion while its mean return decreases when the view on the stock is optimistic and vice versa when pessimistic moreover belief dispersion leads to a higher stock volatility and trading volume we demonstrate that otherwise identical two investor heterogeneous beliefs economies do not necessarily generate our main results

economies of diversification in the banking industry abstract this paper defines a new measure economies of diversification to examine the cost effect of product line expansion this measure is a special case of expansion path subadditivity and contains economies of scope as a special case a nonparametric frontier technique which isolates the effects of inefficiency and scale is used to measure economies of diversification applied to a set of 468 u s depository institutions operating in 1984 we find slight diseconomies of diversification diseconomies of diversification and inefficiency due to the overutilization of resources are found to be more important determinants of bank costs than is the failure to operate at optimal scale

are foreign exchange forecasts rational new evidence from survey data abstract tests of rationality in foreign exchange markets have been inconclusive because of disagreement over the relevant asset pricing model this paper uses a newly available set of data on foreign exchange expectations to directly test the rationality of four foreign currency markets overall the results reject the rational expectations hypothesis

enjoying the quiet life under deregulation not quite summary most empirical studies in the banking literature assume that the alternative profit function is linearly homogeneous in input prices we show that such an assumption is theoretically unwarranted and that its use may yield misleading results we use koetter et al review of economics and statistics 2012 94 2 462 480 as a benchmark to showcase how empirical results can be sensitive to the linear homogeneity assumption contrary to koetter et al we find a positive relation between market power and profit efficiency when this assumption is dropped this relation is slightly weakened after the wave of intrastate and interstate deregulation but not enough to support the quiet life hypothesis copyright 2014 john wiley sons ltd

measuring investors opinion divergence numerous proxies for divergence of investors opinions have been suggested in the empirical accounting and finance literatures i offer a new proxy constructed from proprietary limit order and market order data this allows me to capture additional information on investors private valuations proxies from the extant literature based on publicly available data do not contain such information given my new measure i ask which of the extant proxies correlates best with it in my regression analysis unexplained volume is the best proxy for opinion divergence conditioning on various firm specific and order specific characteristics generally does not change this conclusion the main exception is the sample of firms without ibes forecast dispersion data for which bid ask spread is the best proxy for opinion divergence factor analysis also suggests that unexplained volume is the preferred proxy for opinion divergence

a composite cost function for multiproduct firms with an application to economies of scope in banking the composite cost function the authors propose combines a quadratic output structure with a log quadratic input price structure and is well suited for examining economies of scope subadditivity and other important properties of multiproduct firms to compare the composite model with an appropriate set of alternative functional forms they develop a parsimonious but general specification that nests the standard translog cost function the generalized translog cost function a separable quadratic cost function and the composite cost function an application to economies of scope in banking confirms the advantages of the composite model copyright 1992 by mit press

financial asset holdings and political attitudes evidence from revolutionary england the english parliament s struggle for supremacy against monarchical dictatorship during the civil war 1642 1648 was crucial for the establishment of representative government yet its lessons continue to be debated i exploit novel data on individual mps drawn from 1 842 biographies to show that the conflict was over overseas interests and other factors over which the executive enjoyed broad constitutional discretion rather than over domestic property rights i further exploit the coincidence of individual mps ability to sign legally binding share contracts with novel share offerings by overseas companies to measure the effect of overseas share investment on their political attitudes i show that overseas shareholding pushed moderates lacking prior mercantile interests to support reform i interpret the effect of financial assetholding as allowing new investors to exploit emerging economic opportunities overseas aligning their interests with traders by consolidating a broad parliamentary majority that favored reform the introduction of financial assets also broadened support for the institutionalization of parliamentary supremacy over dictatorial rule jel codes o10 g11 f10 k00 n23 p10

the risk of financial intermediaries this paper reconsiders the formal estimation of bank risk using the variability of the profit function in our model point estimates of the variability of profits are derived from a model where this variability is endogenous to other bank characteristics such as capital and liquidity we estimate the new model on the entire panel of us banks spanning the period 1985q1 2012q4 the findings show that bank risk was fairly stable up to 2001 and accelerated quickly thereafter up to 2007 we also establish that the risk of the relatively large banks and banks that failed in the subprime crisis is higher than the industry s average thus we provide a new leading indicator which is able to forecast future solvency problems of banks

the relation between price changes and trading volume a survey this paper reviews previous and current research on the relation between price changes and trading volume in financial markets and makes four contributions first two empiri cal relations are established volume is positively related to the magnitude of the price change and in equity markets to the price change per se second previous theoretical research on the price volume relation is summarized and critiqued and major insights are emphasized third a simple model ofthe price volume relation is proposed that is consis tent with several seemingly unrelated or contradictory observations and fourth several directions for future research are identified

macroeconomic driven prepayment risk and the valuation of mortgage backed securities we develop a three factor no arbitrage model for valuing mortgage backed securities in which we solve for the implied prepayment function from the cross section of market prices this model closely fits the cross section of mortgage backed security prices without needing to specify an econometric prepayment model we find that implied prepayments are generally higher than actual prepayments providing direct evidence of significant macroeconomic driven prepayment risk premiums in mortgage backed security prices we also find evidence that mortgage backed security prices were significantly affected by fannie mae credit risk and the federal reserve s quantitative easing programs received may 10 2016 editorial decision september 22 2017 by editor stijn van nieuwerburgh

a theory of self enforcing monetary constitutions with reference to the suffolk system 1825 1858 abstract we develop a theory of self enforcing monetary constitutions a monetary constitution is the framework of rules within which money providing and money using agents interact a self enforcing monetary constitutions is upheld by the agents acting within the system it thus does not require external enforcement we describe how the institutional technology of polycentric sovereignty applies to monetary constitutions and show how the 19th century suffolk banking system was characterized by polycentric sovereignty rendering its de facto monetary constitution self enforcing we conclude by briefly discussing the implications of our analysis for the role of the state in maintaining healthy money and banking systems

international trade and institutional change medieval venice s response to globalization international trade can have profound effects on domestic institutions we examine this proposition in the context of medieval venice circa 800 1600 early on the growth of long distance trade enriched a broad group of merchants who used their newfound economic muscle to push for constraints on the executive that is for the end of a de facto hereditary doge in 1032 and the establishment of a parliament in 1172 the merchants also pushed for remarkably modern innovations in contracting institutions that facilitated longdistance trade for example the colleganza however starting in 1297 a small group of particularly wealthy merchants blocked political and economic competition they made parliamentary participation hereditary and erected barriers to participation in the most lucrative aspects of long distance trade over the next two centuries this led to a fundamental societal shift away from political openness economic competition and social mobility and toward political closure extreme inequality and social stratification we document this oligarchization using a unique database on the names of 8 178 parliamentarians and their families use of the colleganza in the periods immediately before and after 1297 we then link these families to 6 959 marriages during 1400 1599 to document the use of marriage alliances to monopolize the galley trade monopolization led to the rise of extreme inequality with those who were powerful before 1297 emerging as the undisputed winners jel codes d02 f10 n43

fairly priced deposit insurance and bank charter policy the thrust of current deposit insurance reform risk based insurance premiums and capital requirements is an effort to price deposit insurance more fairly fairly pricing deposit insurance eliminates inequitable wealth transfers but it does not lead to an efficient equilibrium this paper shows that an alternative charter policy results in an efflcient separating equilibrium this article analyzes the effect of alternative charter policies when deposit insurance is fairly priced the thrust of current deposit insurance reformrisk based capital requirements 1988 and risk based insurance premiums 1994 is an effort to price deposit insurance more fairly chan greenbaum and thakor s 1992 seminal paper dramatically illustrated that fairly pricing deposit insurance is not enough to solve the deposit insurance problem in their model when banks hold nontraded private information assets no equilibrium exists with fairly priced deposit insurance unless banks earn rent or are subsidized fairly pricing deposit insurance eliminates inequitable transfers of wealth but it does not lead to an efficient equilibrium this paper shows that an alternative charter policy gives an efficient separating equilibrium the separating equilibrium segregates the market for insured transactions deposits from private information financial intermediation the analysis in this article provides support for the deposit insurance reform proposal in the recent 1993 national commission on financial institution reform recovery and enforcement ncfirre report to the president and congress and for merton and bodie s 1993 proposal both proposals impose a separating equilibrium that isolates insured transactions accounts and the public information traded assets that secure them from private information assets in the bank s portfolio the formal model developed here is designed to demonstrate the effect of charter policy on the efficiency of market equilibrium in an uncomplicated setting but the main result that a separating equilibrium is more efficient is extremely robust with respect to the model specification the model has two types of financial intermediaries intermediaries that hold nontraded private

why don t we agree evidence from a social network of investors we study sources of investor disagreement using sentiment of investors from a social media investing platform combined with information on the users investment approaches e g technical fundamental we examine how much of overall disagreement is driven by different information sets versus differential interpretation of information by studying disagreement within and across investment approaches overall disagreement is evenly split between both sources of disagreement but within group disagreement is more tightly related to trading volume than cross group disagreement although both sources of disagreement are important our findings suggest that information differences are more important for trading than differences across market approaches

citicorp travelers group merger challenging barriers between banking and insurance abstract the citicorp travelers group merger increased the prospects for new legislation to remove the barriers between banking and insurance resulting in a positive wealth effect for institutions most likely to gain from deregulation analysis of abnormal returns surrounding the merger show that life insurance companies and large banks excluding citicorp and travelers group have significant stock price increases while the returns of small banks health insurers and property casualty insurers are insignificantly different from 0 this analysis provides evidence that investors expect large banks and insurance companies to receive significant benefits from recent congressional legislation removing barriers to bancassurance

affine disagreement and asset pricing models of heterogeneous beliefs can generate rich implications for trading and asset pricing see suleyman basak 2005 for a recent survey when studying such models aggregation often leads to difficulty in computing equilibrium outcomes in this paper we introduce a flexible framework to model heterogeneous beliefs in the economy which we refer to as affine disagreement about fundamentals affine processes see darrel duffie jun pan and kenneth singleton 2000 are appealing as they provide a large degree of flexibility in modeling the conditional means volatilities and jumps for various quantities of interest while remaining analytically tractable our affine heterogeneous beliefs framework allows further for stochastic disagreement among agents about growth rates volatility dynamics as well as the likelihood of jumps and the distribution of jump sizes disagreement about rare disasters provides an interesting case study for our framework research by thomas a rietz 1988 francis longstaff and monika piazzesi 2004 robert j barro 2006 and others show that the possible occurrence of rare disasters that result in severe losses in consumption can have large impact on asset prices however the relatively short sample period and lack of historical precedents of disaster events at least in the united states make it difficult to precisely measure the frequencies of disasters or the size of their asset pricing new risk channels

the benefits of lending relationships evidence from small business data this paper empirically examines how ties between a firm and its creditors affect the availability and cost of funds to the firm we analyze data collected in a survey of small firms by the small business administration the primary benefit of building close ties with an institutional creditor is that the availability of financing increases we find smaller effects on the price of credit attempts to widen the circle of relationships by borrowing from multiple lenders increases the price and reduces the availability of credit in sum relationships are valuable and appear to operate more through quantities rather than prices

volume volatility and the dispersion of beliefs i examine a two period noisy rational expectations model of a futures market and show that the dispersion of expectations about a weighted average of future prices measures both the additional volatility and the additional expected volume of trade associated with noisy information the role played by dispersion helps clarify several stylized facts concerning volume and price behavior specifically dispersion can be a factor contributing to the positive correlation between volume and absolute price changes and the positive correlation between consecutive absolute price changes article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

the price concentration relationship in banking the commonly observed positive correlation between market concentration and profitability may be explained by noncompetitive pricing behavior as argued by the structure performance hypothesis or by the greater efficiency of firms with dominant market shares as argued by the efficient structure hypothesis by examining the price concentration relationship instead of the profit concentration relationship this paper tests the structure performance hypothesis in a manner that excludes the efficient structure hypothesis as an alternative explanation of the results the results strongly support the structure performance hypothesis and are robust with respect to model specification measurement of concentration and econometric technique copyright 1989 by mit press

the efficiency effects of a single market for financial services in europe abstract this paper examines the potential efficiency effects of a single market for financial services in europe the topics covered include universal banking the merger and acquisition process itself cross border ownership and management of financial institutions and the effects of consolidation of financial institutions on the supply of relationship lending services to informationally opaque small businesses the research reviewed here suggests that the creation of a single market for the european financial services industry is not likely to bring about strong efficiency gains and that cross border efficiency barriers may prevent the single market from becoming a reality
