money supply announcements and real interest rates abstract current research on the relation between money and asset prices focuses on the reaction of asset prices to money supply announcements in this paper we use the real interest observed in the u k index linked bond market and the nominal interest rate observed in the nominal bond market to study the reaction of real interest rates and expected inflation to money surprises we find that monetary surprises have a strong effect on inflationary expectations we also find some evidence of a positive reaction of long term real interest rates to the m3 announcement

taking account of governance implications for land use dynamics food prices and trade patterns deforestation mainly caused by unsustainable agricultural expansion results in a loss of biodiversity and an increase in greenhouse gas emissions as well as impinges on local livelihoods countries governance performance particularly with respect to property rights security exerts significant impacts on land use patterns by affecting agricultural yield related technological investment and cropland expansion this study aims to incorporate governance factors into a recursive agro economic dynamic model to simulate governance impacts on land use patterns at the global scale due to the difficulties of including governance indicators directly into numerical models we use lending interest rates as discount rates to reflect risk accounting factors associated with different governance scenarios in addition to a reference scenario three scenarios with high low and mixed divergent discount rates are formed to represent weak strong and fragmented governance we find that weak governance leads to slower yield growth increased cropland expansion and associated deforestation mainly in latin america sub saharan africa south asia and southeast asia this is associated with increasing food prices particularly in sub saharan africa and southeast asia by contrast strong governance performance provides a stable political and economic situation which may bring down deforestation rates stimulate investment in agricultural technologies and induce fairly strong decreases in food prices

monetary innovations and interest rates this paper examines the effect of unexpected weekly changes in the money supply on financial markets l examination of financial market reaction to weekly monetary surprises provides information on how the economy reacts to monetary changes also the reaction to weekly monetary surprises may put real or imagined constraints on federal reserve behavior as noted by tobin a decade ago certainly the rate of growth of the money stock has become the customary capsule form for describing monetary policy and gauging how easy or tight it is for a time it seemed that public preoccupation with this number might itself be a market constraint on the federal reserve believers in monetarism would regard accelerated growth of m1 as the harbinger of more inflation and higher interest rates if such people were to dominate financial markets they would make it difficult for the fed to carry out a rate reducing expansionary policy tobin 1974 p 70 throughout the paper unexpected weekly changes in the money supply monetary innovations are measured by reported changes in the supply of money minus expected changes where expected changes in money are obtained from market survey data changes in current interest rates of various terms to maturity are used to measure the effects of innovations on financial markets

money supply announcements and real economic activity abstract this paper derives testable implications of a model due to siegel 1985 in which interest rates react to announced innovations in the money supply solely because money announcements reveal information about real economic activity tests of these implications yield results inconsistent with the model in addition the results contradict the finding of huizinga and leiderman 1987 that interest rates tended to rise in response to unexpected increases in the monetary base from october 1979 to february 1984

monetary policy regimes expected inflation and the response of interest rates to money announcements this paper examines the response of the term structure of interest rates to weekly money announcements estimated responses for both the pre and post october 1979 periods are first presented then two competing hypotheses involving the policy anticipations and expected inflation effects are formally specified and compared with the estimated responses both hypotheses are found to be consistent with the responses but they have sharply different implications about the federal reserve s short run monetary policy by exploiting these different implications additional empirical results focusing directly on the money stock process support the policy anticipations hypothesis

deforestation and the rule of law in a cross section of countries relationships between deforestation and population pressure income growth and insecure property rights are examined with data from 120 countries insecure property rights are hypothesized to arise from two sources government instability or inability to enforce ownership and an absence of government accountability the former source is captured by measures of general lawlessness such as guerrilla warfare revolution and frequent constitutional change the latter is proxied by variables indicating the type of government executive frequency of political purges and the existence of an elected legislature general support is indicated for the property rights hypothesis and for the effects of population growth

direct tests of the reservation wage property this paper provides the first direct experimental tests of the reservation wages predicted by finite horizon job search models previous indirect tests were based on search duration and search income the authors show that such indirect tests are weak by demonstrating that a naive rule performs essentially as well as the risk neutral model in predicting search duration in contrast direct tests of predicted reservation wages imply rejections of both the naive rule and the risk neutral model the general concave model survives direct tests with reservation wage data as does a specific logistic concave model copyright 1992 by royal economic society

experiments on unemployment benefit sanctions and job search behavior this paper presents the results of an experimental study on unemployment benefit sanctions the experimental set up allows us to distinguish between the effect of benefit sanctions once they are imposed the ex post effect and the threat of getting a benefit sanction imposed the ex ante effect we find that both effects matter moreover the ex ante effect turns out to be substantial and bigger than the ex post effect benefits sanctions stimulate the outflow from unemployment

international interest rates and us monetary policy announcements evidence from hong kong and singapore this paper investigates the responses of market interest rates to us monetary policy announcements for the us and two emerging economies hong kong and singapore which are similar on many respects but have experienced opposite exchange rate regimes in the last twenty years our results based on market expectations extracted from federal fund futures rates document that fomc announcements significantly affect the term structure of interest rate in the us and both asian countries further international interest rate differentials around fomc meeting dates tend to be negative for short maturities with the impact gradually dissipating as bond maturity increases finally for the case of singapore we find that domestic interest rates react to both external and domestic monetary policy announcements with a magnitude that is larger over the full bond maturity spectrum for domestic announcements these results are robust to time varying futures risk premia and alternative measures of interest rates expectations

economic news exchange rates and interest rates the paper esamines the post october 1979 response of exchange rates and interest rates to the new information contained in the first announcement of fifteen us macroeconomic series illarkets respond primarily to monetary news but also to news about the trade deficit domestic inflation and variables that reflect the state of the business cycle for all fifteen macroeconomic variables an increase decrease in interest rates is accompanied by an appreciation depreciation of the dollar which is consistent with models that stress price rigidity and absence of purchasing power parity the effect of economic news on asset prices has received increasing attention in the economic literature because an outcome of the efficient markets rational expectations hypothesis is that flesible asset prices change the moment new information about future fundamentals arrives in the market in the exchange rate literature the role of news has gained importance because structural models have failed to predict most of the variation in exchange rates during the 1970s see imeese and rogoff 1983 researchers were naturally led to investigate the types of news that make exchange rates so volatile and to utilize news in order to test which model of exchange rate determination is consistent with the floating eschange rate experience notable studies are those of dornbusch 1980 frenkel 1981 edwards 1982a b 1983 copeland 1984 and rose 1984 in this paper i also examine the effects of macroeconomic news on eschange rates but i adopt a different more direct strategy one that complements previous work avoids some of its shortcomings and promises interesting conclusions i examine the instantaneous response of exchange rates the moment a piece of economic news hits the market if one can isolate the exact time during a business day when news arrives it is straightforward to examine the response of exchange rates because financial data are continuously available the advantages of the present methodology are many first it is possible to identify the exact types of economic news and how they affect exchange rates second the simultaneity bias which plagues the previous literature on exchange rates and news is not present here the independent variables that represent news can be interpreted as causal the paper was presented at the 1985 meeting ofthe american economic association the author wishes to thank sebastian edwards r w hafer nicholas karamouzis andrew rose and two anonymous referees for helpful comments kim rupert of the money market services for providing the survey data soo kounne for able research assistance and barnard college for research support

why interest rates rise when an unexpectedly large money stock is announced ment of an unexpectedly large growth in the money supply will lead to an immediate increase in interest rates this announcement effect is often taken as confirmation of the monetarist view that the way to bring down interest rates even in the short run is to reduce the rate of money growth in this paper we provide an alternative explanation of the announcement effect that is consistent with the keynesian view that in the short run the way to bring down interest rates is to expand the money supply we do not address the issue of inflationary expectations in a formal way though in the long run we would expect the well known fisher effect to hold looking closely at the announcement effect it is clear that whatever may be the true short run relationship between money growth and interest rates it cannot be inferred from a simple correlation of announcements of changes in the money stock with the resulting changes in interest rates this is because of several properties of the announcement phenomenon that we capture in the model

search at wholesale auto auctions wholesale trade in used cars is conducted by ascending bid auctions with sale subject to the seller s acceptance of the winning bid one out of three times the seller rejects the bid and no trade takes place i model the seller s decision as the outcome of search and thus determined by the winning bid distribution and a reported retail price this market is ideal for testing search theory since all offers whether or not accepted are observed qualitative predictions of the theory in particular the role of the variance are confirmed the quantitative results are more ambiguous

a conservation industry for sustaining natural capital and ecosystem services in agricultural landscapes conservation investment in agricultural landscapes has evolved to take a more market based or business approach however current levels of conservation investment are not likely to mitigate degradation to natural capital and ecosystem services we propose the further evolution of a conservation industry to generate substantially increased investment in conservation in agricultural landscapes particularly from the private sector a mature conservation industry is envisaged as comprising of investors producers and service providers who produce conservation products and services exchanged via market transactions a number of requirements for a viable and effective conservation industry are identified including institutional infrastructure conservation market institutions and regulatory systems information provision quantifying benefits business models and accounting and auditing standards and facilitation entrepreneurship incubation and capacity building a conservation industry requires careful design and planning in order to operate effectively whilst it is not without risk a conservation industry has the potential to increase participation and investment in conservation actions and enhance the sustainability of agricultural landscapes

money supply announcements and interest rates does monetary policy matter abstract most current explanations of the effect of money supply announcements on the rate of interest center on central bank policy this paper analyzes a flexible price macroeconomic model where present and future monetary policy have no influence on either interest rates or real output but monetary data signal information about real economic activity which influences both short and long term real rates of interest the magnitude of the interest rate response is shown to depend on the difference in the income elasticities of currency and deposit demand and the relative size of monetary and real disturbances to the economy

credit constraints and productivity in peruvian agriculture this article evaluates the performance of a rural credit market in peru we develop a model that shows that collateral requirements imposed by lenders in response to asymmetric information can lead not just to quantity rationing but also to transaction cost rationing and risk rationing just like quantity rationing these two additional forms of nonprice rationing adversely affect farm resource allocation and productivity we test the insights of the model using a panel data set from northern peru we estimate the returns to productive endowments for constrained and unconstrained households using a switching regression model we find that consistent with the theory productivity is independent of endowments for unconstrained households but is tightly linked to endowments for constrained households we estimate that credit constraints lower the value of agricultural output in the study region by 26

exchange rates interest rates and money stock announcements a theoretical exposition abstract when the federal reserve announce a larger than anticipated weekly level of the us money stock m1 the dollar appreciates and short term interest rates increase because of an expected liquidity effect but long term interest rates and particularly long run forward interest rates increase because of an expected inflation effect the two effects are not mutually exclusive but coexist when market participants are not completely sure of the fed s policy rule and thus react in a weighted average manner with weights that reflect subjective probabilities about different federal reserve money growth policies

agricultural expansion and deforestation modelling the impact of population market forces and property rights abstract this paper compares four different modelling approaches to agricultural expansion and deforestation and explores the implications of assumptions about the household objectives the labour market and the property rights regime a major distinction is made between population and market based explanations many of the popular policy prescriptions are based on the population approach assuming subsistence behaviour and limited market integration within a more realistic particularly for the long term effects market approach well intentioned policies such as agricultural intensification programmes may boost deforestation many forest frontier contexts are also characterized by forest clearing giving farmers land rights deforestation becomes an investment to the farmer and a title establishment strategy land titling and credit programmes may therefore increase deforestation

organizing a public ecosystem service economy for sustaining biodiversity abstract the core question this paper attempts to address is how social organization needs to respond to biodiversity features and functions in order to achieve its sustainable use scholars have suggested that the governance of complex systems should be dispersed across multiple centers of authority and that any regulative system needs as much variety in the actions that it can take as exists in the system it is regulating further it has been argued that complex ecosystems and biodiversity can successfully be maintained by complex polycentric multi layered governance systems which have a variety of response mechanisms but how should polycentric governance of biodiversity be organized borrowing from the organization of public economies in metropolitan areas we distinguish between production and provision of public ecosystem services and suggest the direction of institutional change for the organization of a public ecosystem service economy if the market alone cannot solve the allocation of public ecosystem services economic efficiency criteria based on hypothetical markets are not sufficient therefore we suggest design principles which go beyond economic efficiency and provide examples of the emergence of polycentric governance from an ethiopian coffee forest conservation project

secrecy of monetary policy and the variability of interest rates this paper addresses the issue of how secrecy of the short run monetary policy objectives affects the behavior of the federal funds rate secrecy is modeled by assuming that financial markets are unc ertain about a parameter in the federal reserve reaction function th ey learn over time about this parameter by means of bayes rule and this learning process is reflected in the time path of interest rates and of reserve aggregates the main result of the paper is that secr ecy tends to increase the volatility of the funds rate and of reserve aggregates copyright 1987 by ohio state university press

the case for methodological pluralism abstract ecology and economics share the same greek root both address complex systems ecology consists of numerous approaches to understanding natural systems energetics population biology food web models hierarchy theory to mention just a few within ecology field knowledge and the reporting of new observations are well respected economics on the other hand is dominated by one pattern of thinking and standard of proof the market model and econometrics within economics field knowledge and observations per se are little valued agreement on a correct method is frequently taken as an indication of the maturity of a science the argument is developed in this paper that all the aspects of complex systems can only be understood through multiple methodologies the agreement on method within economics however seems to reflect stronger pressures within the discipline for conformity than for truth relative to ecology since ecological economics seeks to understand a larger system than either economics or ecology seeks to understand a diversity of methodologies is appropriate and pressures to eliminate methodologies for the sake of conformity should be avoided

inducing risk neutral preferences with binary lotteries a reconsideration abstract we evaluate the binary lottery procedure for inducing risk neutral behavior we strip the experimental implementation down to bare bones taking care to avoid any potentially confounding assumptions about behavior having to be made in particular our evaluation does not rely on the assumed validity of any strategic equilibrium behavior or even the customary independence axiom we show that subjects sampled from our population are generally risk averse when lotteries are defined over monetary outcomes and that the binary lottery procedure does indeed induce a statistically significant shift toward risk neutrality this striking result generalizes to the case in which subjects make several lottery choices and one is selected for payment

changing political regimes and tropical deforestation expansion of agriculture is a main cause of tropical deforestation government policies and weak property rights contribute to this process by encouraging landowners and landless to accelerate land clearing using panel data common to previous studies we add the dimension of new political regimes democratic and non democratic and investigate how the rate of agricultural land expansion in tropical countries depends on the nature and persistence of each regime we find that both new autocratic and democratic regimes have accelerated the expansion of agricultural land thus yielding support to some of the findings in the earlier literature interesting differences emerge between regions with the impact being most pronounced in latin america we interpret these results mainly in the context of increasing tenure and ownership insecurity which in turn is driven by the tendency of new regimes to implement land reforms as a form of social and economic policy or voter payback the argument is developed more formally using a simple competitive land use model that incorporates political regime dependent confiscation risk and agricultural subsidy policy

institutional ecological economics abstract new institutional economics and its forerunners have we argue made important contributions to the evolving agenda of ecological economics the conceptualisation of environmental problems as instances of interdependence and the acknowledgement of positive transaction costs are key insights into the nature of environmental problems we also discuss how plurality of behavioural motivations and limited cognitive capacity have important implications for environmental decision making and its analysis we show how evolutionary and collective action theories offer complementary takes on the choice and change of environmental governance institutions and how the concept of social capital can enrich analyses of environmental governance we conclude that an emerging institutional ecological economics has the greatest relative advantage in analysing the design implementation and effectiveness of environmental governance solutions

the economics of poverty in poor countries this paper which examines recently studied links between 1 poverty high fertility and undernourishment and 2 environmental degradation and civic disconnection in developing countries opens by reviewing the limitations of orthodox discussions of economic institutions and property rights and the orthodox dichotomy that has located the cause of poverty in the suppression of markets the introduction also notes that much of the analysis in this paper is based on data from sub saharan africa and india the next section of the paper summarizes evidence on the magnitude and extent of world poverty section 3 exposes the connection between undernourishment and a persons capacity to work as one of the pathways to the poverty trap sections 4 and 5 consider the dependence of impoverished rural populations on common property resources and how the conventional process of economic growth can break down this system and make certain sections of the population especially vulnerable to economic shocks the next two sections explore the possibility that links between poverty high fertility and environmental degradation may constitute another pathway to the poverty trap the eighth section reviews the methodology of using net national product which includes resource depletion and environmental deterioration as an evaluation criterion and argues that mainstream development economists may have neglected environmental and population problems because they have been relying on the wrong economic indices the final section concludes that a number of policies must be used to improve options for people

monetary shocks and the nominal interest rate this paper reconsiders the effects of monetary shocks on the nominal interest rate in a standard macroeconomic model it is determined that when the policy objective is controlling the money stock money supply shocks generate a situation of excess demand for money the positive relationship between nominal interest rates and monetary innovations in the united states following the 1979 change in regime is thus not puzzling but perfectly consistent with standard theory nominal interest rate decreases are possible only when fine tuning rules are adopted copyright 1992 by the london school of economics and political science

interest rates the forward premium and unanticipated money reply the relationship between the weekly money supply announcement and interest rates has attracted the attention of a large number of economists recent research by cornell 2 3 engel and frankel 5 gavin and karamouzis 6 grossman 7 hardouvelis 9 naylor 10 nichols small and webster 11 roley 12 roley and walsh 13 urich 14 and urich and wachtel 15 indicates a positive correlation between unanticipated changes in the announced money supply and interest rates the consensus on the relationship between unanticipated changes in money supply announcements and interest rates however disappears in the explanation of the phenomenon two competing explanations and thus two hypotheses are offered the main difference between the two hypotheses lies in the interpretation of future money growth conditioned on the information provided by the money supply announcement according to the first hypothesis also known as the expected liquidity hypothesis market participants believe that the federal reserve will promptly offset any deviations in the money supply from its target level this implies that an unanticipated increase in the money supply revealed by the announcement will be followed by a monetary tightening and hence an increase in real short term interest rates according to the second hypothesis also known as the inflation premium hypothesis market participants interpret the change in the money supply revealed by the announcement as a permanent deviation from the money supply target this implies that an unanticipated increase in the money supply will not be offset and hence will raise the inflation premium therefore according to the first hypothesis an increase in nominal interest rates caused by an unanticipated increase in the announced money supply is due to a rise in real interest rates according to the second hypothesis it is due to an increase in the inflationary premium in order to distinguish between the two hypotheses evidence has been presented from the foreign exchange and long term bond markets after analyzing the correlation between unanticipated money growth and the change in the level of spot exchange rates before and after the announcements cornell 2 3 engel and frankel 4 hakkio and pearce 8 and hardouvelis 9 find support for the expected liquidity hypothesis based on the correla

market perceptions of federal reserve policy and the weekly monetary announcements abstract in october 1979 the federal reserve altered its operating procedures emphasizing control of the growth rate of the money stock was the fed able to gain credibility in the market the paper investigates this question by examining the reactions of spot and expected future exchange rates foreign interest rates and long run domestic forward interest rates to the weekly federal reserve announcements of m l both before and after october 1979 the empirical evidence points out that the fed did gain credibility but was unable to establish full credibility the market reactions are consistent with the hypothesis that market participants attached a positive probability to the event that the fed may at some point in the future abandon its money stock targets

middlemen in bilateral search markets this article examines the role of middlemen in bilateral search markets e g employment agencies real estate brokers it is shown that the middleman narrows the set of buyer firm and seller worker types who search seller types with high valuations and buyer types with low valuations drop out of the search market and instead trade through the middleman the middleman also decreases the equilibrium search intensities of those agents who search it is proven that the middleman improves welfare if search is very costly and inefficient and decreases welfare if search is effectively costless and very efficient

ownership risk investment and the use of natural resources the effect of insecure ownership on ordinary investment and natural resource use is examined insecure ownership is postulated to depend on the type of government regime in power and the prevalence of political violence or instability the political determinants of economy wide investment are estimated from cross country data and the results are used to form an index of ownership security when introduced into empirical models of natural resource use this index has a significant and quantitatively important effect on the use of forests and petroleum contrary to conventional wisdom ownership risk slows resource use in some circumstances

economic search an experimental study this paper presents results of experiments designed to test several of the hypotheses present in the theoretical literature on optimal economic search first we test whether the subjects searchers actually search for wages in ways that are consistent with setting an optimal reservation wage we then proceed to determine experimentally the effects of risk aversion increased search costs changes in risk brought about by a mean preserving transformation of the distribution of wage offers the presence or absence of recall the existence of a finite horizon and the searcher s state of knowledge about the underlying distribution of wages in general we find that the searchers exhibit behavior that is consistent with that predicted by theory differences between risk neutral and risk averse searchers are found and the responses of both groups to changes in search costs in the degree of risk or in the state of knowledge are consistent with theoretical predictions

risk attitudes and reservation wages of unemployed workers evidence from panel data abstract this paper studies risk attitudes of unemployed job seekers and their relationship to self reported reservation wages we find that risk aversion is prevalent and that reservation wages decrease slightly over time furthermore risk aversion and reservation wages are negatively correlated

labor market search an experimental study the theoretical results derived from models of economic search have implications which relate to the structure and performance of labor markets utilizing a series of laboratory experiments we attempt to capture many of the features of workers search and also the conditions under which labor markets operate by varying certain of the experimental conditions we are able to determine the searchers responses to changes in the terms of unemployment insurance to the existence of a minimum wage and to different states of information about the underlying distribution of wages in most cases the behavior of the searchers is consistent with that predicted by theory

deforestation property rights and international trade deforestation primarily affects developing countries most developing countries share two characteristics 1 trade liberalization reforms in the last two decades and 2 weak property rights and limited rule of law this paper investigates this second best world first in a stylized model in which trade distortions are eliminated in an economy whose natural resources are subject to open access second empirically in an estimation exercise that disentangles the direct effect of trade on deforestation rates and an indirect effect through its interaction with ownership security in accordance with the theory the results show that only the indirect effect is significant

the effect of relative monetary surprises on spot exchange rates this paper examines the hypothetical relationship between us and canadian monetary surprises and the behaviour of us canadian spot exchange rates past studies have found that positive us monetary surprises were correlated with an appreciating us dollar in foreign exchange markets in this paper it is argued that monetary surprises in the us must be measured relative to foreign monetary innovation rather than in the conventional absolute sense when examining their impact on exchange markets rational investors consider expected returns and risk differentials in the us and local markets jointly in determining whether to be net buyers or sellers of us dollars the monetary actions of both the fed and the central bank operating in the local foreign economy will be considered in the foreign exchange market because of the close synchronization between the weekly money supply announcements in canada and the us it is possible to examine whether the relative or absolute us monetary surprise is more signifi

deforestation and the environmental kuznets curve an institutional perspective institutions for secure property rights and better environmental policies for moving the system towards a sustainable growth path can reduce the height of an environmental kuznets curve ekc relationship between income and deforestation this study examines the impact of these specific institutional factors on the ekc relationship for deforestation across latin american african and asian countries the factors related to agricultural production population economy and governmental policies of each country are hypothesised to affect deforestation results of the latin american countries show significant evidence of an ekc relationship for deforestation and also relevance of the institutional factors to reduce the rate of deforestation improvements in institutions for secure property rights and better environmental policies can thus significantly reduce the rate of deforestation without hindering the level of economic growth evidence also suggests that the effect of agricultural production on deforestation could be halted by strengthening institutional factors there was found to be complementarity between the institutional factors and forest sector polices and an additive effect between the institutional factors and forest products export promotion policies which could also eventually reduce the rate of deforestation

redd and forest transition tunneling through the environmental kuznets curve abstract international attention is focused on finding ways to reduce emissions from deforestation because of the emerging concerns over climate change however the causes of deforestation are rooted in current economic and development paradigms the causes of deforestation also vary across different geographical regions and have implications for the forest transition attempts to reach an international agreement on curbing deforestation have achieved little success despite over 30 years of un negotiations new initiatives from redd reducing emissions from deforestation and forest degradation could provide financial incentives to curb deforestation hence alternative development paths for forest cover changes and forest transition are analyzed for the redd policy within the framework of an environmental kuznets curve ekc for deforestation the ekc models are estimated for geographical regions of latin america africa and asia the results based on the panel data analysis of 43 countries covering the period 1970 1994 provides evidence that an inverted u shaped ekc fits for latin america and africa while a u shaped ekc applies to asia the results also indicate that strengthening agricultural and forestry sector policies are important for curbing deforestation the ekc models estimates could provide guidance for decisions on financing the redd policy as specific to each region

the impact of money on short term interest rates this study reviews empirical evidence from four research methods related to the impact of money on short term nominal rates the studies consistently fail to find evidence supporting the much hypothesized short term negative relationship between money and nominal rates since at least april 1975 reasons for the absence of a negative relationship include the tendency of financial markets to anticipate corrective action by the fed whenever ml deviates from targeted growth ranges and a rapid adjustment of inflationary expectations to changes in money growth

explaining forest transitions the role of governance abstract we analyze how governance may influence competing land uses for forests and thus the occurrence of forest transitions across different low and middle income countries we develop a model of competing land uses that allows for governance to impact the risk of future versus current agricultural and forested land allocations the resulting hypothesis on the relationship between governance and the likelihood of a forest transition is then tested using cross country data the empirical analysis offers strong support for the competing land use framework and indicates that rule of law forest policy and regulatory quality influence forest transitions these findings inform not only the ongoing debate on forest transitions but also policy options for managing such transitions in developing economies

choice modelling and its potential application to tropical rainforest preservation abstract loss of rainforest occurs in part because of a global market failure problem markets routinely transmit signals about international demands for forest products such as timber but fail to transmit signals about demands for preservation to make efficient resource allocation choices decision makers need some framework to estimate the non use values that might be held by an international community for rainforest preservation non market valuation techniques can be used for this purpose but framing and other problems limit the application of the contingent valuation method cvm an alternative technique choice modelling cm appears to hold some promise because it can be used to model complex situations and to frame choices consistent with real life choices in this paper a cm experiment to assess the values that australians hold for rainforest conservation in vanuatu is reported the experiment disguises effectively the issue of interest rainforest conservation in vanuatu within a pool of other conservation locations also the experiment demonstrates that choice tradeoffs may involve a variety of environmental and socio economic factors rather than be concentrated on some monetary tradeoff the results demonstrate that a variety of predictive and valuation tools can be gained from a cm experiment and suggest that further development is warranted

central bank secrecy fed watching and the predictability of interest rates abstract a common criticism of central bank secrecy is the assertion that it will lead to lower forecast accuracy on the part of private agents the model considered here demonstrates that reducing central bank secrecy can actually reduce the forecasting accuracy of many of the private agents in the economy when it is recognized that some agents engage in fed watching and others do not this result comes about because the interest rate process depends in part on the information that agents use in forecasting future interest rates

real time search in the laboratory and the market the standard model of labor market search posits repeated infinite horizon search from a fixed distribution of wages in a stationary environment under these circumstances the optimal search policy has a reservation wage property i e the decision to accept an offer involves a comparison of the offer with a time invariant constant w which itself is a function of the parameters characterizing the search environment a wage offer greater than or equal to w is accepted while any other is rejected and search is continued some early empirical job search studies however accumulated evidence of a declining trend in reservation wages over the course of an unemployment spell 1 since then several theoretical explanations for the declining reservation wage profiles have emerged all of which relax the stationarity assumption of the standard model for example reuben gronau 1971 assumes searchers have finite lives kenneth burdett 1977 gerard j van den berg 1990 james albrecht and susan vroman 2005 and others model short term unemployment benefits albrecht pieter a gautier and vroman 2006 permit directed search to heterogeneous prospects 2 john p danforth 1979 and silvio rendon 2006 consider general liquidity con strained search and burdett and tara vishwanath 1988 model learning about the job offer distribution behavioral explanations for declining reservation wages have been suggested by braunstein and schotter 1981 schotter and braunstein 1982 and others in this paper we present the results of the first ever to our knowledge real time search laboratory experiment performed in an effort to investigate this falling res ervation wage phenomenon where field studies of unemployed search often rely on strong identifying assumptions to recover searchers unobservable reservation wages in the laboratory we are able to elicit subjects complete reservation wage profiles in an incentive compatible manner 3 further in the laboratory we are able to

commodity prices money surprises and fed credibilit strict monetarist theory in an extreme form holds that excessive money growth or the expectation of future money growth shows up immediately in the rapid inflation of goods prices however it is widely argued that for most goods prices are in fact sticky in the short run and reflect money growth only in the long run if one seeks a sensitive market measure of the perceived looseiless or tightness of monetary policy one must look elsewhere than at the general price level interest rates being determined in quickly adjusting financial markets are free to respond immediately to expectations regarding monetary policy in 1981 and 1982 every friday at 4 10 p m eastern standard time the federal reserve board would announce the money stock for the week ending nine days previously if the announced money stock was different from what the market had been expecting interest rates generally jumped in the same direction clearly they were responding to revisions of the expected future path of the money stock but nominal interest rates are an ambiguous indicator of expectations on the one hand an announced increase in the money stock may be received by the market as indicating a higher

property rights genetic resources and biotechnological change it is well recognized that wild genetic resources the genetic constitutions of plants and animals have substantial social and economic value as repositories of genetic information today genetic information provides direct and indirect inputs into plant breeding programs the development of natural products including drugs and pharmaceuticals and increasingly sophisticated applications of biotechnology 2 recognition of the potential of wild genetic resources in the development of drugs has led the national cancer institute to initiate a massive plant collection project 3 which is a follow up to an earlier 1970s project that sought to identify drugs effective against a variety of cancers and to look at the immune system effects of various drugs it is estimated that 70 percent of the 3 000 species known to have anticancer properties are found in the tropical forests 4 in recent years a number of widely used drugs have been developed from plants including two important anticancer drugs derived from the rosy periwinkle found in tropical madagascar with the recent major breakthroughs in biotechnology the future potential of these resources seems limitless species that have no current commercial application have useful natural chemicals or are as yet undiscovered never

understanding the coexistence of formal and informal credit markets in piura peru summary this paper examines why farm households seek informal loans in piura peru where formal lenders offer loans at lower interest rates a panel data econometric analysis reveals that the informal sector serves various types of clients households excluded from the formal sector but also households that prefer informal loans because of lower transaction costs or lower risk an in depth examination of contract terms and loan technologies permits an accurate comparison of effective loan costs and contractual risk across sectors and reveals that proximity and economies of scope enjoyed by informal lenders enable them to substitute information intensive screening and monitoring for contractual risk and supply these various types of clients

trade tragedy and the commons we develop a theory of resource management where the degree to which coun tries escape the tragedy of the commons and hence the de facto property rights regime is endogenously determined three forces determine success or failure in resource management the regulator s enforcement power the extent of har vesting capacity and the ability of the resource to generate competitive returns without being extinguished the model can explain heterogeneity across coun tries and resources in the effectiveness of resource management and it predicts that changes in prices population and technology can cause transitions to better or worse management regimes jel p14 q21 q22 q23 q32 many of the world s major renewable resource stocks are in a state of decline this is true for capture fisheries for forests in developing countries and for many measures of the biosphere s health other renewable resources including many species of wildlife marine mammals and coral reefs are also under threat while poverty and government corruption are surely respon sible for some of this record particular emphasis is often placed on the potentially damaging role played by international trade this emphasis is not surprising given that natural resource products are a key export for much of the developing world and property rights over renewable resources are both difficult to define and poorly enforced but property rights are not an immutable country characteristic such as weather mineral deposits or topography they are instead market institutions developed to facilitate transactions and protect scarce resources consequently changes in prices technology and other effects of market integration may alter the de facto property rights regime and lead to impacts quite dif ferent from those predicted by existing analyses the purpose of this paper is to examine renew able resource use within a framework where the enforcement of property rights and hence the efficacy of resource management is endogenously determined we develop a theory where an existing government regulates the use of a renewable resource by a set of agents who have a right to harvest the resource could be a fishery forest stock aquifer etc and we assume it is local and therefore contained within one country the govern ment sets rules limiting harvests but agents may cheat on these allocations and risk punishment property rights are endogenous in this framework because the government must account for agents incentive to cheat as a result the effective protection for the resource or what we refer to as the de facto property rights regime may be far from perfect even though property rights would be perfectly enforced if there was no monitoring problem
