measuring and improving the performance of customs valuation controls an illustration with gabon modern customs administrations aim to both facilitate legal trade and combat fraud to meet this dual objective many customs administrations in developing countries must give risk management a highly prominent role in this context of modernisation this paper first provides stylised facts on the performance of the customs controls carried out at the gabon border then we compare gabon s granular import customs data with international trade statistics based on this comparison we identify undetected fraud and present a methodology to target ex post audits finally we define indicators to monitor the performance of customs valuation controls

estimating the effect of hierarchies on information use theory suggests that greater hierarchical distance between a subordinate and his boss makes it more di cult to share abstract and subjective information in decision making a novel data set put together from credit dossiers of large corporate loan applicants enables us to observe the information collected by loan o cers and also how it is used by the ultimate loan approving o cer we flnd that greater hierarchical geographical distance between the information collecting agent and the loan approving o cer leads to less reliance on subjective information and more on objective information by exploiting non linearities in the assignment rules that determine an applicant s hierarchical distance and using information collecting agent flxed efiects we show that our result cannot be driven by endogenous assignment of applicants we also flnd that higher frequency of interactions between the information collecting agent and loan approving o cer both over time and through geographical proximity helps mitigate the efiects of hierarchical distance on information use our results show that hierarchical distance in uences information use and highlights the importance of human touch in communication

internal capital markets and the competition for corporate resources this article examines the role of corporate headquarters in allocating scarce resources to competing projects in an internal capital market unlike a bank headquarters has control rights that enable it to engage in winner picking the practice of actively shifting funds from one project to another by doing a good job in the winner picking dimension headquarters can create value even when it cannot help at all to relax overall firm wide credit constraints the model implies that internal capital markets may sometimes function more efficiently when headquarters oversees a small and focused set of projects this article analyzes the process by which internal capital markets channel limited resources to different uses inside a company in so doing it seeks to address two related sets of questions first what is the fundamental economic rationale for creating an internal capital market that is under what circumstances can it make sense to combine several technologically distinct projects under one roof and have them seek funding from corporate headquarters as opposed to setting them up as stand alone companies that each raise external financing on their own second given this rationale what is the optimal size and scope of an internal capital market should headquarters be involved in funding a large number of projects or just a few and should these projects be unrelated to one another or in similar lines of business the answers to both sets of questions flow from the insight that in a credit constrained setting where not all positive npv projects can be financed headquarters can create value by actively reallocating scarce funds across projects for example the cash flow generated by one division s activities may be taken and spent on investment in another division where the returns are higher or alternatively one division s assets may be used as collateral to raise financing that is then diverted to the other division simply put individual projects must compete for the scarce funds and headquarters job is to pick the winners and losers in this competition

capital budgeting in multidivision firms information agency and incentives author s bernardo antonio e cai hongbin luo jiang abstract we consider a firm with two investment projects divisions each run by a manager who can provide i unverifiable information about the quality of either or both projects and ii unverifiable access to valuable resources that can enhance the cash flows of either or both projects we then examine the extent to which capital allocation and managerial compensation schemes can be designed jointly to mitigate the information and incentive problems within the firm we find that the firm underinvests in capital in both projects relative to the first best level optimal managerial profit sharing increases in the quality of both projects and managers underinvest resources in both projects interestingly the underinvestment problem in one project is less severe when the other project is higher quality this effect will be stronger when the moral hazard problem is more acute and project returns are more highly correlated we also predict that multi division firms will invest more less than single division firms when other divisions in the firm perform well poorly

capital markets and firm organization how financial development shapes european corporate groups we investigate the effect of financial development on the formation of european corporate groups because cross country regressions are hard to interpret in a causal sense we exploit exogenous industry measures to investigate a specific channel through which financial development may affect group affiliation internal capital markets using a comprehensive firm level data set on european corporate groups in 15 countries we find that countries with less developed financial markets have a higher percentage of group affiliates in more capital intensive industries this relationship is more pronounced for young and small firms and for affiliates of large and diversified groups our findings are consistent with the view that internal capital markets may under some conditions be more efficient than prevailing external markets and that this may drive group affiliation even in developed economies this paper was accepted by bruno cassiman business strategy

the economics of university computer provision a case study in public production and cost is the provision of computer services in british universities provided efficiently the pattern of expenditure in the last twenty years is explored and a study is made of current spending across universities variations in unit computing costs and the output of computing expreience is studied for british universities using conventional cost and production function estimation in addition the three demensional production surface for the output of computer provision is estimated using distance weighted techniques this case study has more general applicability to other areas of public production and cost

what s different about banks abstract negotiable certificates of deposit cd s trade in the capital market in competition with other securities like commercial paper and bankers acceptances if cd s must pay lenders competitive monetary interest the reserve tax on cd s is borne by bank borrowers viability of the tax means there must be something special about bank loans that makes some borrowers willing to pay higher interest rates than those on other securities of equivalent risk moreover there must be something special about banks that prevents other intermediaries from competing to assure that it never pays to finance loans with cd s

the bright side of internal capital markets we examine capital expenditure decisions of discount firms in response to wal mart s entry into their markets before wal mart s entry focused incumbents and discount divisions of diversified incumbents are similar in size geographic dispersion and firm debt levels however discount divisions of diversified firms are significantly more productive after wal mart s entry diversified firms are quicker to either exit the discount business or stay and fight also their capital expenditures are more sensitive to the productivity of their discount business internal capital markets function well as transfers are away from the worsening discount divisions it appears diversified firms make better investment decisions

tariffs enforcement and customs evasion evidence from india we examine the effect of tariff policies on evasion of customs duties in the context of the trade reform in india of the 1990s by exploiting the variation in tariff rates across time and products we identify a robust positive elasticity of evasion with respect to tariffs a second contribution of the paper is to provide some evidence on the impact of enforcement while we cannot identify the direct impact of enforcement on evasion we can establish the extent to which enforcement related factors such as product characteristics that determine the ease of detection of evasion affect the evasion elasticity the results render support to the hypothesis that improvements in enforcement can reduce the responsiveness of evasion to tariffs

accounting for inequality trends decomposition analyses for the uk 1971 86 eight explanations for uk income inequality trends between 1971 and 1986 are assessed by pooling evidence from inequality index decompositions by population sub group and by income source the principal causes of the aggregate trends were a mixture of changes in earnings inequality employment structure and unemployment but this mixture changed over time the impact of wage inequality changes on income inequality changes fell during the 1970s and 1980s reflecting the secular decline in the importance of employment earnings for household income packages unemployment changes had their largest impact at the start of the 1980s between 1981 and 1986 self employment income changes appear to have had the largest influence

asymmetric information and the structure of the banking industry abstract we analyze the effects of informational asymmetries on the market structure of the banking industry in a multi period model of spatial competition in the process of lending incumbent banks gather proprietary information about their clients acquiring an advantage over potential entrants we show that these informational asymmetries are important determinants of the industry structure and of banks strategic behavior contrary to traditional models of horizontal differentiation the steady state equilibrium is characterized by a finite number of banks even in the absence of exogenous fixed costs in addition less concentrated industry structures may be associated with higher interest rates

are politically connected firms more likely to evade taxes evidence from tunisia are politically connected firms more likely to evade taxes using tax social security and customs records from tunisia in which firms owned by former president ben ali and his family are identified this paper demonstrates that connected firms were more likely to evade taxes ceteris paribus connected firms are 4 6 more likely not to submit a tax declaration in spite of registering workers and or customs transactions and 8 4 more likely to report anomalously low sales when submitting a tax declaration

affiliated firms and financial support evidence from indian business groups abstract we investigate the functioning of internal capital markets in indian business groups we document that intragroup loans are an important means of transferring cash across group firms and are typically used to support financially weaker firms evidence suggests that an important reason for providing support may be to avoid default by a group firm and consequent negative spillovers to the rest of the group consistent with such spillovers the first bankruptcy in a group is followed by significant drops in external financing investments and profits of other firms in the group and an increase in their bankruptcy probability

the determinants and labour market effects of lifelong learning despite the policy importance of lifelong learning there is very little hard evidence from the uk on a who undertakes lifelong learning and why and b the economic benefits of lifelong learning this paper uses a rich longitudinal panel data set to look at key factors that determine whether someone undertakes lifelong learning and then models the effect of the different qualifications acquired via lifelong learning on individuals economic outcomes namely wages and the likelihood of being employed those who left school with o level qualifications or above were much more likely to undertake lifelong learning undertaking one episode of lifelong learning also increased the probability of undertaking more lifelong learning we found little evidence of positive wage effects from lifelong learning however males who left school with only low level qualifications do earn substantially more if they undertake a degree via lifelong learning we also found important positive employment effects from lifelong

multinational banks in the crisis foreign affiliate lending as a mirror of funding pressure and competition on the internal capital market abstract we investigate how the lending activities abroad of a multinational bank s local and hub affiliates have been affected by funding difficulties during the financial crisis we find that affiliates local deposits and performance have been stabilizing loan supply by contrast relying on short term wholesale funding has increasingly proven to be a disadvantage in the crisis which has seen inter bank and capital markets freeze by introducing a liable approximate measure for intra bank flows we detect competition for intra bank funding between the affiliates abroad as well as an increasing focus on the parent bank s home market activities in addition the more an affiliate abroad relies on intra bank funding in the crisis the greater its dependence on its parent bank having a stable deposit and long term wholesale funding position we consider changes in long term lending to the private sectors of 40 countries by the affiliates of the 68 largest german banks to obtain a more precise picture we clean our lending data from valuation effects

internal capital markets and corporate politics in a banking group we analyze proprietary internal capital allocation data from a large retail banking group consisting of member banks and a headquarters organization we find that capital allocations from headquarters compensate for deposit shortfalls on the bank level suggesting that the headquarters offers deposit smoothing to member banks we then analyze how the distribution of influence within the group relates to capital allocations and lending behavior more influential banks are allocated more funds from headquarters and their loan growth is less sensitive to their deposit base the effects of influence are stronger if banks have a greater demand for deposit smoothing

tax rates and tax evasion evidence from missing imports in china tax evasion by its very nature is difficult to observe we quantify the effects of tax rates on tax evasion by examining the relationship in china between the tariff schedule and the evasion gap which we define as the difference between hong kong s reported exports to china at the product level and china s reported imports from hong kong our results imply that a one percentage point increase in the tax rate is associated with a 3 percent increase in evasion furthermore the evasion gap is negatively correlated with tax rates on closely related products suggesting that evasion takes place partly through misclassification of imports from higher taxed categories to lower taxed ones in addition to underreporting the value of imports

political connections and tariff evasion evidence from tunisia are politically connected firms more likely to evade taxes this paper presents evidence suggesting firms owned by president ben ali and his family were more prone to evade import tariffs during ben ali s reign evasion gaps defined as the difference between the value of exports to tunisia reported by partner countries and the value of imports reported at tunisian customs were correlated with the import share of connected firms this association was especially strong for goods subject to high tariffs and driven by underreporting of unit prices which diminished after the revolution consistent with these product level patterns unit prices reported by connected firms were lower than those reported by other firms and declined faster with tariffs than those of other firms moreover privatization to the ben ali family was associated with a reduction in reported unit prices whereas privatization per se was not

anniversary article a perspective on asymmetric information incentives and intrafirm resource allocation the paper asymmetric information incentives and intrafirm resource allocation by harris kriebel and raviv was published in the june 1982 issue ofmanagement science in this article written as part of this journal s 50 year anniversary celebration we highlight the significance of the harris et al paper for research in managerial accounting we first formulate and solve a continuous version of the harris et al model to illustrate the key assumptions and findings of their paper we then review several strands of the resource allocation literature in managerial accounting that have taken their inspiration either directly or indirectly from the work of harris et al

asymmetric information incentives and intrafirm resource allocation this paper considers the question how should a firm allocate a resource among divisions when the productivity of the resource in each division is known only to the division manager obviously if the divisions as represented by their managers are indifferent among various allocations of the resource the headquarters can simply request the division managers to reveal their private information on productivity knowing that the managers have no incentive to lie the resource allocation problem can then be solved under complete or at least symmetric information this aspect is a flaw in much of the recent literature on this topic i e there is nothing in the models considered which makes divisions prefer one allocation over another thus although in some cases elaborate allocation schemes are proposed and analyzed they are really unnecessary in the model we develop a division can produce the same output with less managerial effort if it is allocated more resources and effort is costly to the manager we further assume that this effort is unobservable by the headquarters so that it cannot infer divisional productivity from data on divisional output and managerial effort given these assumptions we seek an optimal resource allocation process our results show that certain types of transfer pricing schemes are optimal in particular if there are no potentially binding capacity constraints on production of the resource then an optimal process is for each division to choose a transfer price from a schedule announced by the headquarters division managers receive a fixed compensation minus the cost of the resource allocated to them at the chosen transfer price resources are allocated on the basis of the chosen transfer prices if there is a potentially binding constraint on resource production a somewhat more complicated but similar scheme is required

cheating ourselves the economics of tax evasion no government can announce a tax system and then rely on taxpayers sense of duty to remit what is owed some dutiful people will undoubtedly pay what they owe but many others will not over time the ranks of the dutiful will shrink as they see how they are being taken advantage of by the others thus paying taxes must be made a legal responsibility of citizens with penalties attendant on noncompliance but even in the face of those penalties substantial tax evasion exists and always has the history of taxation is replete with episodes of evasion often notable for their inventiveness during the third century many wealthy romans buried their jewelry or stocks of gold coin to evade the luxury tax and homeowners in eighteenth century england temporarily bricked up their fireplaces to escape notice of the hearth tax collector webber and wildavsky 1986 p 141 this essay reviews what is known about the magnitude nature and determinants of tax evasion with an emphasis on the u s income tax alm 1999 andreoni erard and feinstein 1998 and slemrod and yitzhaki 2002 offer more comprehensive recent reviews of the literature it then places this information into a conceptual and policy context

coincident correlations of growth and cash flow in banking abstract prior empirical research indicates that loan growth in the banking industry is positively related to cash flow i offer an alternative methodology that is better able to capture the effect of cash flow on loan growth while controlling for the potentially coincident effect of loan growth on cash flow using a sample of 171 389 observations on banks 1986 2007 i find that causality runs more consistently from growth to cash flow than from cash flow to growth this extends prior empirical research by houston and james 1998 and campello 2002 on cash flow sensitivities in the banking industry

why do low educated workers invest less in further training several studies document that low educated workers participate less often in further training than high educated workers this article investigates two possible explanations low educated workers invest less in training because of 1 the lower economic returns to these investments or 2 their lower willingness to participate in training controlling for unobserved heterogeneity we find that the economic returns to training for low educated workers are positive and not significantly different from those for high educated workers however low educated workers are significantly less willing to participate in training we show that this lesser willingness to train is driven by economic preferences and personality traits

the economics of the arab spring summary a singular failure of the arab world is the absence of a private sector that is independent competitive and integrated with global markets this paper argues that private sector development is both a political and regional challenge in so far as the private sector generates incomes that are independent of the rent streams controlled by the state it can pose a direct political challenge it is also a regional challenge since fragmented markets deny scale economies to firms and entrench the power of insiders we argue that overcoming regional economic barriers constitutes the single most important collective action problem facing the region since the fall of ottoman empire

are internal capital markets efficient using segment information from compustat we find that the investment by a segment of a diversified firm depends on the cash flow of the firm s other segments but significantly less than it depends on its own cash flow the investment by segments of highly diversified firms is less sensitive to their cash flow than the investment of comparable single segment firms the sensitivity of a segment s investment to the cash flow of other segments does not depend on whether its investment opportunities are better than those of the firm s other segments

multinational banks and the global financial crisis weathering the perfect storm we use data on the 48 largest multinational banking groups to compare the lending of their 199 foreign subsidiaries during the great recession with lending by a benchmark group of 202 domestic banks contrary to earlier more contained crises parent banks were not a significant source of strength to their subsidiaries during the 2008 09 crisis as a result multinational bank subsidiaries had to slow down credit growth about twice as fast as domestic banks this was particularly the case for subsidiaries of banking groups that relied more on wholesale market funding domestic banks were better equipped to continue lending because of their greater use of deposits a relatively stable funding source during the crisis we conclude that while multinational banks may contribute to financial stability during local bouts of financial turmoil they also increase the risk of importing instability from abroad

the returns to education macroeconomics we offer an extensive summary and a critical discussion of the empirical literature on the impact of human capital on macro economic performance with a particular focus on uk policy we also highlight methodological issues and make recommendations for future research priorities taking the studies as a whole the evidence that human capital increases productivity is compelling though still largely divided on whether the stock of education affects the long run level or growth rate of gdp a one year increase in average education is found to raise the level of output per capita by between three and six percent according to augmented neo classical specifications while leading to an over one percentage point faster growth according to estimates from the new growth theories still over the short run planning horizon four years the empirical estimates of the change in gdp are of similar orders of magnitude in the two approaches the impact of increases at different levels of education appear to depend on the level of a country s development with tertiary education being the most important for growth in oecd countries education is found to yield additional indirect benefits to growth more preliminary evidence seems to indicate that type quality and efficiency of education matter for growth too

inequality measurement an axiomatic approach the theory of inequality measurement is examined using some basic axioms which extend the pigou dalton principle of transfers from these basic axioms various inequality indices may be derived as an alternative to ad hoc methods or to methods involving prior specification of a social welfare function the key idea is the concept of distance between two income shares conventional inequality indices are analysed in terms of their implied distance functions

to steal or not to steal firm attributes legal environment and valuation data on corporate governance and disclosure practices reveal wide within country variation that decreases with the strength of investors legal protection a simple model identifies three firm attributes related to that variation investment opportunities external financing and ownership structure using firm level governance and transparency data from 27 countries we find that all three firm attributes are related to the quality of governance and disclosure practices and firms with higher governance and transparency rankings are valued higher in stock markets all relations are stronger in less investor friendly countries demonstrating that firms adapt to poor legal environments to establish efficient governance practices

investment cash flow sensitivities are useful a comment on kaplan and zingales arecent paper in this journal by kaplan and zingales reexamines a subset of erms from work of fazzari hubbard and petersen and criticizes the usefulness of investment cash eow sensitivities for detecting enancing constraints we show that the kaplan and zingales theoretical model fails to capture the approach employed in the literature and thus does not provide an effective critique moreover we describe why their empirical classiecation system is eawed in identifying both whether erms are constrained and the relative degree of constraints across erm groups we conclude that their results do not support their conclusions about the usefulness of investment cash eow sensitivities in a recent paper in this journal kaplan and zingales 1997 hereinafter kz argue that investment cash eow sensitivities do not provide useful evidence about the presence of enancing constraints because kz use a subset of the same erms and the same regressions as fazzari hubbard and petersen 1988 hereinafter fhp and claim page 176 that fhp can legitimately be considered the parent of all papers in this literature it is appropriate that we respond based on a simple theoretical model kz reach the provocative conclusion page 211 that the investment cash eow sensitivity criterion as a measure of enancial constraints is not well grounded in theory in section i we show that the kz model does not capture the theoretical approach employed in fhp and many subsequent studies most of the kz paper attempts to show that empirical investment cash eow sensitivities do not increase monotonically with the degree of enancing constraints within the 49 low dividend erms from the fhp sample in section ii we explain why the kz classiecation of the degree of constraints is eawed in identifying both whether or not erms are constrained absolute constraints as well as the relative degree of constraints across erms as a result we argue in section iii that there is no expected ex ante pattern for the

what enhances mathematical ability a cross country analysis based on test scores of 15 year olds this paper examines the mathematical abilities of 15 year olds in a range of countries which participated in the 2003 cycle of the oced s programme for international student assessment pisa utilising information on the scores obtained by individual students in the mathematical part of the pisa assessment we use a range of indicators from the literature on inequality and poverty to evaluate the mathematical performance of participating countries since data from pisa contained a wealth of information on the circumstances of the students in terms of their home and school environment we identify and examine the relative influence of factors which serve to enhance the mathematical performance of students in the pisa assessment

capital rationing and organizational slack in capital budgeting this paper reconciles three stylized facts about capital budgeting in firms and shows that they are tied to the presence of asymmetric information among the several members of the firm each with his or her own objectives and decisions the facts of interest are 1 the existence of organizational slack 2 the rationing of resources within organizations 3 the stated cut off rate for accepting capital projects in firms is often greater than the market rate of interest organizational slack is defined as the excess of resources allocated over the minimum necessary to accomplish the tasks assigned resource rationing is defined as the under allocation of resources i e an increase in the amount allocated would generate revenues in excess of its costs rationing and slack are both manifestations of ex post inefficiencies an lp model is used to show that these inefficiencies can occur in ex ante efficient organizational designs when asymmetric information is present the optimal allocation policy involves a hurdle rate criterion in which the hurdle rate is strictly in excess of the cost of capital thus inducing rationing in some states of the world typically resources are optimally allocated such that slack exists in other states the optimal allocation policy trades off these two inefficiencies
