the nba and the influx of international basketball players the determinants of salaries for professional athletes in the national basketball association nba are examined to investigate how international athletes have fared relative to athletes trained in the united states it is found that international basketball players were paid a large premium above other players of similar skills and characteristics for the 1996 97 and 1997 98 seasons after which the premium disappeared this temporary premium is likely attributable to a winner s curse experienced by nba teams before investing significant resources in scouting and evaluating international players

securitization and the balance sheet channel of monetary transmission abstract this paper shows that the balance sheet channel of monetary transmission is stronger for us banks that securitize their assets this finding is different in spirit from the widely found negative relationship between financial development and the strength of the lending channel of monetary transmission focusing on the balance sheet channel and using bank level observations we find that securitizing banks are more sensitive to borrowers balance sheets and that monetary policy has a greater impact on this sensitivity for securitizing banks the optimality conditions from a simple partial equilibrium framework suggest that the positive effects of securitization on policy effectiveness could be due to the high sensitivity of security prices to policy rates

competitive equilibrium in the credit market under asymmetric information abstract we study a competitive credit market equilibrium in which all agents are risk neutral and lenders a priori unaware of borrowers default probabilities admissible credit contracts are characterized by the credit granting probability the loan quantity the loan interest rate and the collateral required the principal result is that in equilibrium lower risk borrowers pay higher interest rates than higher risk borrowers moreover the lower risk borrowers get more credit in equilibrium than they would with full information no credit is rationed and collateral requirements are higher for the lower risk borrowers

islamic banking and finance recent empirical literature and directions for future research this paper examines the recent empirical literature in islamic banking and finance highlights the main findings and provides a guide for future research early studies focus on the efficiency production technology and general performance features of islamic versus conventional banks whereas more recent work looks at profit and loss sharing pls behaviour competition risks as well as other dimensions such as small business lending and financial inclusion apart from key exceptions the empirical literature suggests no major differences between islamic and conventional banks in terms of their efficiency competition and risk features although small islamic banks are found to be less risky than their conventional counterparts there is some evidence that islamic finance aids inclusion and financial sector development results from the empirical finance literature dominated by studies that focus on the risk return features of mutual funds finds that islamic funds perform as well if not better than conventional funds there is little evidence that they perform worse than standard industry benchmarks some recent evidence however suggests that islamic bond sukuk issuance destroys value for shareholders

financial intermediation as a beliefs bridge between optimists and pessimists this paper proposes a new framework for understandingnancial intermediation in contrast to previous research we consider a setting in which intermediaries possess no inherent information processing or monitoring advantages instead in an economy with overly optimistic entrepreneurs who require funding from overly skeptical pessimistic investors we show that intermediaries can arise endogenously in such a setting only a rational intermediary will be su ciently optimistic tond it worthwhile to invest in a technology for screening entrepreneurs projects and yet be pessimistic enough to use this technology our framework produces implications consistent with heretofore unexplained stylized facts and a number of others which are as of yet untested

input subsidy programs in sub saharan africa a synthesis of recent evidence input subsidy programs have once again become a major plank of agricultural development strategies in africa ten african governments spend roughly us 1 billion annually on input subsidy programs isps amounting to 28 6 of their public expenditures on agriculture this article reviews the microlevel evidence on isps undertaken since the mid 2000s we examine the characteristics of subsidy beneficiaries crop response rates to fertilizer application and their influence on the performance of subsidy programs the impacts of subsidy programs on national fertilizer use and the development of commercial input distribution systems and finally the impact of isps on food price levels and poverty rates the weight of the evidence indicates that the costs of the programs generally outweigh their benefits findings from other developing areas with a higher proportion of crop area under irrigation and with lower fertilizer prices factors that should provide higher returns to fertilizer subsidies than in africa indicate that at least a partial reallocation of expenditures from fertilizer subsidies to r d and infrastructure would provide higher returns to agricultural growth and poverty reduction however because isps enable governments to demonstrate tangible support to constituents they are likely to remain on the african landscape for the foreseeable future hence the study identifies ways in which benefits can be enhanced through changes in implementation modalities and complementary investments within a holistic agricultural intensification strategy among the most important of these are efforts to reduce the crowding out of commercial fertilizer distribution systems and programs to improve soil fertility to enable farmers to use fertilizer more efficiently the challenges associated with achieving these gains are likely to be formidable

sports jobs and taxes the economic impact of sports teams and stadiums this book examines the economic impact of new stadiums or a sports franchise on the local economy it explores such general issues as the appropriate method for measuring economic benefits and costs the source of the bargaining power of teams in obtaining subsidies from local government the local politics of attracting and retaining teams the relationship between sports and local employment and the importance of stadium design in influencing the economic effects of a facility the book also contains case studies of major league sports facilities in baltimore chicago cincinnati cleveland indianapolis san francisco and the twin cities and of minor league baseball stadiums and spring training facilities the primary conclusions are the sports teams and stadiums are not a source of local economic growth and employment the size of the net subsidy exceeds the financial benefit of a new stadium and cities are probably willing to subsidize sports teams because of the intense popularity of sports among a substantial proportion of voters and businesses and the leverage that teams enjoy from the monopoly position of professional sports leagues

the economic consequences of professional sports strikes and lockouts post evaluation of the effects of the lockout an examination of the impact of past work stoppages in professional football and basketball can shed some light on the potential impact of the nba lockout as well as the viability of professional sports as engines of economic growth in cities the parameter estimates from a reduced form empirical model of the determination of real per capita income in 37 standard metropolitan statistical areas smsas over the period 1969 1996 suggest that prior work stoppages in professional football and baseball had no impact on the economies of cities with franchises further the departure of professional basketball from cities had no impact on their economies in the following years these results refute the idea that attracting professional sports franchises represents a viable economic development strategy

female income and the divorce decision evidence from micro data escalating divorce rates during the 1960s and 1970s led to large numbers of academic investigations into the causes of divorce most of these studies concentrated on a significant increase in female income that resulted from rising female labour force participation rates the difficulty with quantifying these arguments is that it is possible to observe the income of married females or it is possible to observe the income of divorced females but it is not possible to observe both outcomes simultaneously this research attempts to resolve these difficulties by using sample selection techniques to correct for possible bias from simple observation of the income of married and divorced females

the impact of seed vouchers on poverty reduction among smallholder rice farmers in nigeria in response to the global food crisis of 2008 the united states agency for international development usaid funded an emergency rice initiative eri program to boost rice production in nigeria the supplementary seed voucher program implemented alongside the eri adopted a randomized control trial to grant randomly selected farmers access to subsidized certified improved rice seed using the seed voucher system svs in this study we provide a consistent estimate of the impact of the svs on poverty reduction using mixed methodologies such as inverse propensity score weighing ipsw and the local average treatment effect late estimation techniques results show that the svs has a positive and statistically significant impact on annual household income and per capita consumption expenditure this study shows that availability of good quality seed at an affordable price can raise agricultural productivity increase household income and contribute to poverty reduction

an exploration of competitive signalling equilibria with third party information production the case of debt insurance in markets in which sellers know more about product quality than buyers but cannot convey their superior information either by directly issuing costly signals of the spence type or by successfully funding the production of information i suggest another way in which the informational asymmetry problem can be resolved a third party can produce the necessary information at a cost and use it to price a service consumed by the sellers buyers can then observe a seller s choice of service consumption level and be well informed in equilibrium in this framework i construct a model in which a borrower s choice of insurance coverage signals its default probability to lenders and explore the properties of the resulting signalling equilibrium in a variety of cases subsequent to akerlof s provocative paper 1 the analysis of equilibria in markets with asymmetrically informed agents has been the subject of considerable enquiry akerlof s novel insight was the observation that such markets can fail in the sense that the demand at any price is zero this market failure can be prevented however if a priori imperfectly informed buyers of a given product can somehow revise their initial conditional estimates of product quality so that prices are consistent with quality in an equilibrium bhattacharya 2 3 ross 9 and spence 12 13 14 have suggested that one way of achieving this is to allow sellers of the product or service to issue costly signals of the quality offered for sale in a rational equilibrium prospective buyers could use these signals to discriminate accurately between products of differing quality campbell and kracaw 4 have recently suggested another possibility that sellers can make side payments to information producers to acquire the necessary information at a cost and convey it to the market this paper explores yet another distinct way of resolving the information asymmetry problem the market structure considered here involves three parties a group of sellers each aware of the quality of its own product a set of buyers who perhaps satisfy the rational expectations assumption that they are aware of the average quality of the products in the market but are unable to distinguish one seller from the other on the basis of product quality and third party information producers who expend resources to produce information about the quality of each product offered for sale these information producers recover the cost of information acquisition by using their knowledge to structure and price some fixed quality service that they provide to

compensating differentials and the social benefits of the nfl abstract we use hedonic rent and wage equations to measure compensating differentials in central cities and metropolitan areas with franchises of the national football league rents are about 8 percent higher in the central cities but this impact may not carry over to broader geographical areas wages are about 2 percent lower in areas with teams but the standard error on this parameter is large the central city results indicate that sports franchises appear to be a public good once these quality of life benefits are included in the calculus the large public expenditure on new stadiums appears to be a good investment for cities and their residents

securitization and bank performance theory suggests that securitization provides financial institutions with an opportunity to lower the cost of funding improve credit risk management and increase profitability in practice however it might lead to adverse consequences through a number of indirect channels therefore the net impact of securitization on bank performance is ambiguous this study aims to evaluate whether banks improve their performance through the use of the securitization market by applying a propensity score matching approach in other words we build a counterfactual group of banks to assess what would have happened to the securitizing banks had they not securitized using us commercial banking data from 2001 to 2008 we first test these hypotheses using univariate analysis and find that securitizing banks are on average more profitable institutions with higher credit risk exposure and higher cost of funding however the propensity score matching analysis does not provide evidence of significant causal effects of securitization on the performance of banks therefore securitization does not seem to outperform alternative funding risk management and profitability improvement techniques used by banks that have ex ante similar characteristics to those securitizing our evidence raises important questions about the motives for banks increasing securitization activities and consequent implications for the banking system

securitization a financing vehicle for all seasons securitization is considered to be one of the biggest financial innovations of the last century it is also regarded as both a catalyst and a solution to the 2008 financial crisis once a popular method of financing the mortgage and consumer credit markets aspects of the global securitization market are now struggling to revive in this paper i discuss the role that ethics played in securitization prior to the 2008 financial crisis and find that it is not an obvious story of moral failures but rather that it lies in more subtle elements of the financial system the ethics uncertainty role in the securitization story is one of flawed incentives and the shifting of responsibility for handling risk the role of securitization and the ethics of risk transfer have rarely been discussed explicitly in the literature the historical origins of securitization and lessons learned from previous flawed uses of the process are also provided i also detail the various global institutional reform proposals that have taken place moving forward it is crucial to understand the causes consequences and ethical implications of securitization in the financial crisis so as to help individuals and managers better assess risk align incentives and design appropriate policy responses

information reliability and a theory of financial intermediation this paper is an analysis of when it will be beneficial for agents engaged in the production of information to form coalitions the model is cast in a financial market framework thus leading to an identification of conditions sufficient for the existence of financial intermediaries intermediation is shown to improve welfare if informational asymmetries are present and the information generated to rectify these asymmetries is potentially unreliable the usual appeal to transactions costs to explain intermediation is not needed

traditional and nontraditional banking an information theoretic approach abstract this paper uses a multiproduct approach to analyze the costs of a sample of large banks where bank outputs are measured to account for the different types of information produced by banks diseconomies of scope are found between traditional banking activities of originating and monitoring loans and nontraditional activities of loan selling and buying this suggests maintaining fire walls between commercial bank functions and investment bank functions after the glass steagall act is repealed will not sacrifice joint production economies it also suggests that arguments for repeal of the act based on the existence of such economies are ill founded

making markets for structured mortgage derivatives abstract this paper distinguishes between securitization in which simple pass through instruments are created and structuring in which mortgages derivative claims are created the point is to explain how structuring a transaction brings value to a deal s underwriter briefly an underwriter must defeat arbitrage between pass throughs and derivatives the potential for market segmentation and price discrimination by the underwriter is used to analyze the structuring process in the course of the analysis the legal rules for trusts the algebraic rules for structuring and the limits on permissible price discrimination are discussed results for an actual transaction illustrate the important features of the analysis

banks and loan sales marketing nonmarketable assets theories of financial intermediation predict that bank loans should not be marketable because of moral hazard problems banks will not conduct credit risk analysis or monitor borrowers if they are not at risk for failing to perform these services throughout most of history bank loans have not in fact been marketable yet by the end of the 1980 s the amount of commercial and industrial loan sales outstanding had grown to over 250 billion from trivial amounts at the beginning of the decade to explain the opening of this loan sales market we present a model of incentive compatible loan sales that allows for implicit contractual features between loan sellers and loan buyers we then test for the presence of these features using a sample of over 800 recent loan sales

impact of conservation agriculture technology on household welfare in zambia this article examines the determinants and impact of conservation agriculture ca technology adoption on farm household welfare in zambia to account for selection bias from both observable and unobservable factors an endogenous switching regression model is employed to estimate the impact of the technology on continuous outcomes like farm output throughput accounting ratio tar poverty gap and severity of poverty a recursive bivariate probit model is however used for the estimation of impact of adoption on a binary outcome like poverty headcount the empirical findings demonstrate that the adoption of ca technology increases maize output and farm tar and reduces household poverty moreover the results reveal that farmers years of schooling social networks access to credit extension services and machinery as well as soil quality positively influence adoption of ca technology

introduction economics of betting markets economists have long been interested in the economics of betting markets as exemplified by the excellent survey articles by sauer 1998 and vaughan williams 1999 this is perhaps not surprising

moral hazard and information sharing a model of financial information gathering agencies we propose a theory of information gathering agencies in a world of informational asymmetries and moral hazard in a setting in which true firm values are certified by screening agents whose payoffs depend on noisy ex post monitors of information quality the formation of information gathering agencies groups of screening agents is justified on two grounds first it enables screening agents to diversify their risky payoffs second it allows information sharing the first effect itself is insufficient despite the risk aversion of screening agents and the stochastic independence of the monitors used to compensate them this paper develops a model that explains the formation of financial institutions which acquire and process information for the purpose of certifying asset qualities but do not get involved in funding the model makes two basic assumptions the first is that there is an informational asymmetry in the capital market involving insiders possessing more accurate information about the true economic values of their firms than outsiders and the second is that those engaged in the production of information to rectify this asymmetry can gain from sharing their information examples of the information gathering agencies iga s we study are creditrating agencies financial newsletters standard and poor s value line investment counselors credit bureaus etc iga s are distinct from funding financial intermediaries ffi s like banks and credit unions that in addition to acquiring and processing information also issue claims against themselves fund their customers needs and transform asset characteristics from a modeling standpoint a key distinction between iga s and ffi s is that in the case of the latter outsiders depositors for instance do not necessarily have to assess the quality of the intermediary s information since the intermediary can be made accountable for this quality through the positions it takes in the screened assets thus models that explain ffi s focus on how the contracts offered by the intermediary ensure information reliability without reliance on explicit monitoring on the other hand because of the absence of loan and deposit type contracts to dissipate informational problems a model explaining iga s must rely on monitoring related mechanisms

the use of loan sales and standby letters of credit by commercial banks abstract this paper examines the incentives banks have to engage in off balance sheet activities such as commercial loan sales and the issuance of standby letters of credit slcs i show that loan sales and loans backed by slcs have payoff characteristics similar to secured debt like secured debt off balance sheet activities permit banks to sell a portion of the cash flows associated with new investment oppurtunities this ability permits banks to invest in loans with positive net present values that they would pass up if restricted to deposit financing an examination of the risk premium on large certificates of deposit provides evidence consistent with the model

wages rents and the quality of life this study focuses on the role of wages and rents in allocating workers to locations with various quantities of amenities the theory demonstrates that if the amenity is also productive then the sign of the wage gradient is unclear while the rent gradient is positive the theory is extended to include the housing market and nontraded goods these extensions require little modification of the conclusion the empirical work on wages shows that the regional wage differences can be explained largely by these local attributes with the use of site price data implicit prices are estimated and quality of life rankings for the cities are computed

taking a new look at empirical models of adoption average treatment effect estimation of adoption rates and their determinants this article shows that the observed sample adoption rate does not consistently estimate the population adoption rate even if the sample is random it is proved that instead the sample adoption rate is a consistent estimate of the population joint exposure and adoption rate which does not inform about adoption per se likewise it is shown that a model of adoption with observed adoption outcome as a dependent variable and where exposure to the technology is not observed and controlled for cannot yield consistent estimates of the determinants of adoption the article uses the counterfactual outcomes framework to show that the true population adoption rate corresponds to what is defined in the modern policy evaluation literature as the average treatment effect ate which measures the effect or impact of a treatment on a person randomly selected in the population in the adoption context a treatment corresponds to exposure to the technology the article uses the ate estimation framework to derive consistent nonparametric and parametric estimators of population adoption rates and their determinants and applies the results to consistently estimate the population adoption rates and determinants of the nerica new rice for africa rice varieties in c ote d ivoire the ate methodological approach developed in the article has significant policy implications with respect to judging the intrinsic merit of a new technology in terms of its potential demand by the target population independently of issues related to its accessibility and in terms of the decision to invest or not in its wide scale dissemination

european capitals of culture and life satisfaction this paper analyses whether hosting the most prestigious european cultural event the european capital of culture has an impact on regional economic development and the life satisfaction of the local population we show that european capitals are hosted in regions with above average gdp per capita but do not causally affect the economic development in a significant way surprisingly using difference in difference estimations a negative effect on the wellbeing of the regional population is found during the event since no effect is found before the event reverse causality and positive anticipation can be ruled out the negative effect during the event might result from dissatisfaction with the high levels of public expenditure transport disruptions general overcrowding or an increase in housing prices

the emergence and regulation of contingent commitment banking abstract in but a relatively few years banking has changed considerably now it is very much a business of making contingent promises or commitments and even just a decade ago it was not recognizing change is apparently easier though than accounting for it or than not worrying about it in this paper an attempt is made to account for the change from traditional to contingent commitment banking an attempt which must however be regarded as less than brilliantly successful and responding to the concern that has been expressed by among others federal reserve officials it is argued that even if banking keeps on changing until the last vestige of the traditional has disappeared the federal reserve need not in the end be less effective as the u s monetary authority than it is at present there is also a concern shared by some federal reserve officials that if change persists then unless bank regulatory policy is altered appropriately financial stability will be increasingly threatened that could be but as is argued in the paper it is far from obvious that more capital and or a risk adjusted capital requirement will make bank failures rarer than they otherwise would be

estimating outcome distributions for compliers in instrumental variables models in imbens and ingrist 1994 angrist imbens and rubin 1996 and imbens and rubin 1997 assumptions have been outlined under which instrumental variables estimands can be given a causal interpretation as a local average treatment effect without requiring functional form or constant treatment effect assumptions we extend these results by showing that under these assumptions one can estimate more from the data than the average causal effect for the subpopulation of compliers one can in principle estimate the entire marginal distribution of the outcome under different treatments for this subpopulation these distributions might be useful for a policy maker who wishes to take into account not only differences in average of earnings when contemplating the merits of one job training programme vs another we also show that the standard instrumental variables estimator implicitly estimates these underlying outcome distributions without imposing the required nonnegativity on these implicit density estimates and that imposing non negativity can substantially alter the estimates of the local average treatment effect we illustrate these points by presenting an analysis of the returns to a high school education using quarter of birth as an instrument we show that the standard instrumental variables estimates implicitly estimate the outcome distributions to be negative over a substantial range and that the estimates of the local average treatment effect change considerably when we impose nonnegativity in any of a variety of ways

the effect of professional sports on the earnings of individuals evidence from microeconomic data this article examines the impact of professional sports franchises in labour markets using data from the march supplement to the current population survey cps for workers employed in specific occupational groups in all large us cities from 1983 to 2002 results from a standard wage model suggest that professional football franchises increase average hourly and weekly earnings of males employed in these occupations but professional baseball franchises reduce them these results support growing evidence that professional sports affect labour markets however the mixed nature of the association between sport and earnings provides little economic justification for government subsidies for professional sport

collateral and rationing sorting equilibria in monopolistic and competitive credit markets the authors examine how market structure affects credit allocation under universal risk neutrality and asymmetric information about borrowers they consider both monopolistic and perf ectly competitive banks and examine the role of collateral in each ca se when a bank is a monopolist on the loan side they find collatera l is never used and asymmetric information results in reduced bank le nding under perfect competition collateral has a useful sorting rol e moreover rationing is possible even with collateral availability and perfectly elastic deposit supply in this setting the authors sh ow co signers are valuable social welfare properties of the monopoly and competitive equilibria are also compared copyright 1987 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

loan sales and the cost of bank capital this paper considers a model where banks may improve the returns on loans by monitoring borrowers bank regulation together with competitive deposit and equity financing can give banks an incentive to sell loans but the extent of their loan selling is limited by a moral hazard problem a solution is given for the optimal design of the bank loan buyer contract that alleviates this moral hazard problem an explanation is also given as to why some banks might buy loans and why loan sales volume has recently increased banks practice of making loans and then selling them to other institutions and individuals has grown in popularity an important example in the development of loan selling has been the increase in banks mortgage loans that are insured and pooled under the authority of the government national mortgage association gnma and then sold to secondary market investors recently however there has been a dramatic rise in the volume of other types of loans being sold especially by money center banks portions of commercial loans originated by these larger banks are being sold to smaller banks foreign banks and other financial and nonfinancial institutions in addition banks car loans and credit card receivables have also been pooled and sold to institutions and individuals selling loans that were once considered nonmarketable assets a process that has been termed asset securitization may be signalling the start of a fundamental change in the commercial banking business the leading banks in loan selling operations now view themselves more as originators and distributors of loans rather than as institutions holding loans as assets the potentially large impact of loan sales on the future of commercial banking naturally evokes the question of what incentives exist for banks to sell loans in this paper we show that loan sales allow some banks to finance loans less expensively than by traditional deposit or equity issue because bank funds received via loan sales can avoid costs associated with required reserves and

costly information production equilibria in the bank credit market with applications to credit rationing in this paper we explore the nature of equilibria in an asymmetrically informed bank credit market in which credit applicants know their own intrinsic default risks but potential lenders can discover these default risks only by expending resources to produce information the resolution of informational asymmetries in the capital market is in the contemporary view considered a very important function served by financial intermediaries like commercial banks and in the opinion of some even the primary justification for their existence 17 we therefore focus on how the presence of asymmetric information in particular the response of expected profit maximizing banks to it affects the equilibrium prices and quantities of credit offered in the banking system

information reusability competition and bank asset quality this paper explains the recent decline in bank asset quality using the notion of information reusability banks are viewed as information processors they exist because of their advantage in extracting the surplus associated with the reusability of borrower specific information it is shown that a bank s incentive to screen loan applicants and hence maintain the quality of its assets depends on the surplus this screening can produce which in turn depends on information reusability two recent changes in banks operating environment are increased competitition and greater temporal volatility in borrower credit risks the former has directly reduced banks informational surplus while the latter has impaired information reusability hence screening expenditures have been reduced and the diminution of screening has lowered the quality of bank assets it is also shown that an increase in deposit insurance premia has an effect similar to that of narrowing interest spreads and therefore will result in reduced asset screening and impaired asset quality

a performance assessment of the angolan soccer league abstractthis article analyses the technical efficiency of the angolan soccer league from 2008 to 2014 using a translog distance stochastic frontier model the greene stochastic frontier model presented in 2005 and kumbhakar stochastic frontier model presented in 1990 are adopted and the covariates used include luanda location funding by the oil company sonangol club supported by rich fans and club relegated during the period policy implications are then derived

bank funding modes securitization versus deposits abstract we examine a bank s choice of whether to fund the loans it originates by emitting deposits or to sell the loans to investors with common knowledge of loan quality and laissez faire banking we find that the choice is irrelevant with asymmetric information but without government intervention we find that better quality assets will be sold securitized and poorer quality assets will be funded with deposits public regulation can influence the bank s choice subsidies can cause a bank to favor deposit funding but mutual funds and third party insurers may mitigate the effects of governmental subsidies

cluster sample methods in applied econometrics inference methods that recognize the clustering of individual observations have been available for more than 25 years brent moulton 1990 caught the attention of economists when he demonstrated the serious biases that can result in estimating the effects of aggregate explanatory variables on individual specific response variables the source of the downward bias in the usual ordinary least squares ols standard errors is the presence of an unobserved state level effect in the error term more recently john pepper 2002 showed how accounting for multi level clustering can have dramatic effects on t statistics while adjusting for clustering is much more common than it was 10 years ago inference methods robust to cluster correlation are not used routinely across all relevant settings in this paper i provide an overview of applications of cluster sample methods both to cluster samples and to panel data sets

productivity and welfare effects of nigeria s e voucher based input subsidy program summary in an attempt to go beyond the so called smart subsidies nigeria has embarked on a potentially innovative mobile phone based input subsidy program that provides fertilizer and improved seed subsidies through electronic vouchers in this article we examined the productivity and welfare effects of the program using household level data from rural nigeria the article employed instrumental variable regression approach to control for the potential endogeneity of the input subsidy program our results suggest that the program is effective in improving productivity and welfare outcomes of beneficiary smallholders the size of the estimated effects suggests a large improvement in productivity and welfare outcomes moreover the distributional effects of the program suggest no heterogeneity effects based on gender and farm land size these results are robust to using alternative measurements of program participation the benefit cost ratio of 1 11 suggests that the program is marginally cost effective overall our results suggest that while improving average productivity is a good outcome for improving food security improving the distributional outcome of the program by targeting the most disadvantaged groups would maximize the program s contribution to food security and poverty reduction

the solvency of financial institutions in spain lessons from securitization on analysing a sample of spanish banks we find that securitization has a slightly negative impact on the soundness of the issuing entity an unbalanced dynamic panel model was estimated using the forward orthogonal deviations gmm method and used to analyse 537 traditional securitizations issued by 61 banks between 1998 and 2012 the analysis revealed that the entities soundness became weaker immediately prior to the crisis but this effect became insignificant after 2007 securitization has facilitated a process of regulatory capital arbitrage leading to lower capital requirements while at the same time giving rise to a slight worsening of the quality of the originators portfolios it was found that profitability liquidity and inflation positively affect solvency while changes in short term interest rates affect it negatively

large sport events and unemployment the case of the 2006 soccer world cup in germany this study analyses on the basis of a multivariate analysis ex post the effects on the jobs market of a soccer world cup in this case the 2006 world cup held in germany in addition to three methods already used for other analyses in studies of sporting events an extended difference in difference estimate is used in order to compare the development of the numbers of unemployed in the 12 world cup venues with the development of the numbers of unemployed in 63 other german cities the results demonstrate that in none of the respective match venues did the effect of the sporting event on unemployment differ significantly from zero

capital regulation and insured banks choice of individual loan default risks abstract how bankers choose the riskiness of their individual assets is an important question it is well known that fixed premium deposit insurance leads a bank to prefer a high variance asset portfolio but its effect on individual asset choice has not been carefully evaluated this paper demonstrates how bank examination procedures and capital adequacy standards can make the value of a bank s deposit insurance contract concave in individual asset risks insured bankers may therefore have a rational preference ceteris paribus for relatively safe individual loans even while they prefer risky portfolio returns the model s implications for loan securitization and the federal regulators new risk based capital standards are discussed

the economics of sports facilities and their communities since the 1950s taxpayers have been the primary investors in stadia built for the use of privately owned professional sports teams team owners have argued that sports facilities boost local economic activity however economic reasoning and empirical evidence suggest the opposite public support for stadia is also driven by demand for community image and owners of sports teams supply a scarce input into image enhancement participation in the major league for which they have been able to extract monopoly rents from dispersed taxpayers we suggest reforms to dissipate the monopoly sports leagues exercise when negotiating with host communities for their teams
