deregulation consolidation and efficiency evidence from the spanish insurance industry this paper provides new information on the effects of deregulation and consolidation in financial services markets by analyzing the spanish insurance industry the sample period 1989 98 spans the introduction of the european union s eu third generation insurance directives which deregulated the eu insurance market deregulation has led to dramatic changes in the spanish insurance market the number of firms declined by 35 average firm size increased by 275 and unit prices declined significantly in both life and non life insurance we analyze the causes and effects of consolidation using modern frontier efficiency analysis to estimate cost technical and allocative efficiency as well as using malmquist analysis to measure total factor productivity tfp change the results show that many small inefficient and financially underperforming firms were eliminated from the market due to insolvency or liquidation as a result the market experienced significant growth in tfp over the sample period consolidation not only reduced the number of firms operating with increasing returns to scale but also increased the number operating with decreasing returns to scale hence many large firms should focus on improving efficiency by adopting best practices rather than on further growth

seasonality differential access and interlinking of labour and credit this article explains the interlinking of rural labour and credit transactions in terms of differential access to credit markets and seasonality a model is developed which incorporates not only seasonality and differential access but also several other explanations for interlinking suggested in the literature moreover it allows one to test the sensitivity of the results to differing powers on the part of landowners relative to working households

tournaments and sharecropping this paper explores the incentive effects of a renewal clause in a lease the basis of selection is rank order performance the authors findings in the context of a principal agent model are as follows in order to extract greater effort from tenants i e agents the landlord the principal must commit to a reward scheme that provides a part of the second period income to the winner on the basis of past performance this payment provides insurance and creates incentives for agents to work harder in the current period it also makes the contract efficient ex post and renegotiation proof copyright 1996 by the london school of economics and political science

the costs of distribution in the uk life insurance market the cost of direct and independent distribution in the uk life insurance sector over the period 1990 1997 is examined this is a novel contribution to the literature that until now has focused almost solely on distribution in the non life sector unlike the non life sector the distribution of life insurance is complicated by the existence of investor protection policies which in the uk are believed to have increased the use of independent agents using a pooled data set of 44 companies between 1990 and 1997 this study finds little evidence for such a view cost benefits are found for firms focusing in one mode of distribution from a modelling of the distribution decision this finding maybe attributed to firms choosing distribution systems which match the transactional problems associated with their product mix and or mode of corporate governance

the determinants of efficiency and productivity in the swiss insurance industry abstract using state of the art frontier efficiency methodologies we study the efficiency and productivity of swiss insurance companies in the life property casualty and reinsurance sectors from 1997 2013 in this context we provide the first empirical analysis of internationalization strategies of insurance companies a topic of high interest in the business and economics literature but one that has to date not been the focus of efficiency studies in the insurance sector we find that productivity and efficiency have improved with regard to property casualty and reinsurance in the case of life insurance productivity and efficiency diminished however life insurance firms with higher levels of international business exhibit superior efficiency levels we observe that diversification strategies directed to the european market are more beneficial compared to those targeting markets outside of europe

agent discretion and the choice of insurance marketing system this article argues that different insurance marketing organizations arise as a means to minimize the costs of correctly matching policyholder risks with insurance coverage when policyholders are easily sorted without sales agent participation in screening exclusive dealing will be the preferred marketing organization when agent information is important for risk placement independent agency may be preferred empirical support for our theory is obtained from analysis of compensation contracts and market shares of the different marketing forms exclusive dealers are found to be prevalent in relatively standardized homogeneous product lines and markets and their agents receive less profit based compensation than those of independent agency insurers these findings are consistent with our theory

the liability insurance market t his paper offers an overview of the u s liability insurance market and the link between its performance and developments in tort law over the last few decades the dominant feature of the insurance market has been the intermittent periods of rapidly rising premiums and cutbacks on the availability of coverage the insurance cycle appears to be increasing in amplitude and since the 1960s has been concentrated increasingly in liability lines an episode of rising premiums in the late 1960s was followed by a six year period of declining and eventually negative growth rates in total liability insurance premiums over the 1975 1977 period the annual growth rate jumped to 30 percent then followed another period of declining real premiums until premiums nearly tripled in 1984 1986 accompanied by cancellations of policies and massive withdrawal of insurers from some lines this crisis had an economic impact beyond the insurance market leading to the withdrawal of many goods and services from u s markets in mid 1987 the market began to turn again with premiums falling by as much as 40 percent for some commercial policies since then aggregate revenue from premiums has been relatively stable the liability insurance market is intertwined with the tort system in addition to providing incentives to avoid accidents the tort system allocates the risks of accident costs in providing compensation for accident victims the modern expansion of liability in tort law as described by priest in this issue represents a shift in the burden of supplying insurance from first party insurance markets to liability or third party insurance markets clearly this shift will

characteristics of mexican economic growth empirical testing of some latin american structuralist hypotheses abstract this article examines a series of hypotheses about the latin american industrialization process put forward by the structuralist school of thought using mexico as a test case in particular it examines the relationship between the distribution of income and associated patterns of consumption and industrial structure and its implications on demand constraints growth constraints employment constraint and multinational control the results indicate that the modern traditional dichotomy based on durable versus non durable consumer goods is not the best way to examine this relationship since the consumption patterns for durable goods do not show a homogeneous behavior when distribution changes overall it was found that growth and employment constraints and multinational control seem to get more exacerbated under greater inequality with respect to the demand constraints no definite conclusion can be made because of the mentioned heterogeneity in the response of durable goods to changes in distribution and the lack of information on relative excess capacity and or dynamic linkages of the different sectors

economies of scale and scope in the finnish non life insurance industry abstract economies of scale and scope in finnish non life insurance are studied the production process is separated into cost and portfolio management functions firms expand their branch network to either gain market power or informational advantages there are diseconomies of scale at firm and economies of scale at branch level and economies of scope in production large firms in the non life insurance industry pay a substantial premium to gain market power via branch networks the retained premiums curve of portfolio management is u shaped and a positive function of the number of branches

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

market structure and the efficiency of european insurance companies a stochastic frontier analysis abstract this paper is motivated by the progressive liberalisation of the european insurance market in recent years it uses stochastic frontier analysis to estimate flexible fourier cost functions for european insurance companies separate frontiers are estimated for life non life and composite companies we adopt a maximum likelihood approach to estimation in which the variance of both one sided and two sided error terms is modelled jointly with the frontiers this approach allows us to simultaneously control for the impact of heteroskedasticity on the estimation of scale economies as well as estimating the effect of firm size and market structure on x inefficiency the study draws on standard poor s eurothesys data set of financial reports for the period 1995 to 2001 this provides technical and non technical accounts at year end for life non life and composite insurance businesses in 14 major european countries our estimates suggest that over this period most european insurers were operating under conditions of decreasing costs increasing returns to scale and that company size and domestic market share were significant factors determining x inefficiency larger firms and those with high market shares tend to have higher levels of cost inefficiency

the competitive effects of exclusive dealing evidence from the u s beer industry abstract several recent theoretical articles have modeled the effects of exclusive dealing contracts that restrict dealers to selling a single brand yet detailed empirical analysis of the impact of exclusivity on actual market outcomes has been lacking i analyze a unique set of firm level data on nearly 400 beer distributors in the united states the impacts of economies of scale and restrictions on distributor promotional activities on the use of exclusive dealing are measured as well as the effects of exclusivity on costs prices and output the results support the view that exclusive dealing serves to minimize manufacturer dealer incentive conflicts and enhances social welfare

stagnation income distribution and monopoly power the deceleration in the rate of industrial growth in the indian economy since the middlesixties initially interpreted by some as a temporary downward deviation from trend hasnow come to be generally accepted as reflecting long run tendencies towards stagnation several explanations for these tendencies have been offered bhagwati and desai 1970 and bhagwati and srinivasan 1975 have focused on inefficiencies and the misallocationof resources arising from industrial policies pursued by the government others chakravarty 1974 raj 1976 and vaidyanathan 1974 among them have emphasisedthe sluggishness of agricultural growth which is alleged to have retarded industrial growthby limiting markets and the supply of wage goods and raw materials a third view reflectedin srinivasan and narayana 1977 for example has put the blame on a slackening of invest ment demand due to lower public investment but does not explain why public investmentfell or why its fall restrained industrial growth finally there is the explanation put forthin bagchi 1970 1975 1982 in nayyar 1978 and in parts of mitra 1977 that inequali ties in income distribution have resulted in a limited demand for industrial goods reducedincentives for investment and therefore reduced growth this view seems to suggest apositive relation between growth and income equality which is opposed to the generallyaccepted idea derived from cambridge growth models that higher growth requires greaterinequality the purpose of this paper is to examine the last explanation by considering the inter action between growth and income distribution in an underdeveloped economy with thehelp of a simple macroeconomic model the model is a stylisation of the indian economy so that we will be able to use the model to assess the argument that a deceleration in therate of growth of the indian industrial economy could have been caused by an unequaldistribution of income the argument will not be made that this income distributional con straint is the binding constraint on industrial growth the model will merely examine theinternal consistency of the argument that a bad income distribution could explain stagnation in the sense of reduced growth and show that in the indian context as in other similarcontexts this argument can be put forward in explaining stagnation our argument is first presented with a highly simplified schematisation of the indianeconomy which we shall call the basic model the economy modelled produces only one

price dispersion in an automobile insurance market from automobile insurance data for alberta over the period 1974 81 we find thatpremiums are highly correlated across driver classes in a given year but that premiums for a given driver class are not correlated over a period of more than 5 years firms relative market shares among drivers over age 25 and married males under 25 are inversely related to their deviations from the mean premiums in these driver classes the variance of real premiums decreases with the numberof firms in the market and increases with the real loss cost per car insured and the number of cars insured from these results we conclude that the price dispersion in automobile insurance in alberta is based on costly consumer search

entry size distribution scale and scope economies in the life insurance industry existing empirical studies in the life insurance industry in the united states and canada find evidence of economies of scale in at least some aspects of the production of life insurance with consequent implications for the efficiency of life insurance markets however these empirical results are inconsistent with the institutional facts in the industry first overall economies of scale houston and simon 1970 are at odds with the evidence that over a substantial period of time the life insurance market in canada and the united states has supported a large and growing number of independent firms of vastly different sizes 1 second if economies of scale account for the differences in firm size with small firms ex

the robustness of output measures in property liability insurance efficiency studies abstract we empirically examine two methods for measuring output in property liability insurer efficiency studies the value added approach and the flow or financial intermediation approach the approaches are not mutually consistent the value added approach is closely related to traditional measures of firm performance but the flow approach is not in addition efficient value added approach firms are less likely to go insolvent while firms characterized as efficient by the flow approach are generally more likely to fail we also find that the theoretical concern regarding the value added approach s use of losses as a measure of output is not validated empirically

free and slave labor in the antebellum south perfect substitutes or different inputs the substitutability between free and slave labor is examined and the permissibility of aggregating the two in to a single labor variab le is investigated using a translog production function slaves on large cotton farms worked in gangs free labor was not observed to do so despite this previous research has aggregated free and slave labor and employed functional forms imposing strong restrictions on substitution estimation of the translog function shows that simple additive aggregation is not acceptable on large farms slaves and free labor were complements while on small nongang farms they were substitutes copyright 1988 by mit press

efficiency in the international insurance industry a cross country comparison the purpose of this paper is to provide new empirical evidence on frontier efficiency measurement in the international insurance industry a topic of great interest in the academic literature during the last several years a broad efficiency comparison of 6462 insurers from 36 countries is conducted different methodologies countries organizational forms and company sizes are compared considering life and non life insurers we find a steady technical and cost efficiency growth in international insurance markets from 2002 to 2006 with large differences across countries denmark and japan have the highest average efficiency whereas the philippines is the least efficient regarding organizational form the results are not consistent with the expense preference hypothesis which claims that mutuals should be less efficient than stocks due to higher agency costs only minor variations are found when comparing different frontier efficiency methodologies data envelopment analysis stochastic frontier analysis

the effect of organizational structure on efficiency evidence from the spanish insurance industry this paper provides new information on the effects of organizational structure on efficiency by analyzing spanish stock and mutual insurers over the period 1989 1997 we test the efficient structure hypothesis which predicts that the market will sort organizational forms into market segments where they have comparative advantages and the expense preference hypothesis which predicts that mutuals will be less efficient than stocks technical cost and revenue frontiers are estimated using data envelopment analysis the results indicate that stocks and mutuals are operating on separate production cost and revenue frontiers and thus represent distinct technologies in cost and revenue efficiency stocks of all sizes dominate mutuals in the production of stock output vectors and smaller mutuals dominate stocks in the production of mutual output vectors larger mutuals are neither dominated by nor dominant over stocks in the cost and revenue comparisons thus large mutuals appear to be vulnerable to competition from stock insurers in spain overall the results are consistent with the efficient structure hypothesis but are generally not consistent with the expense preference hypothesis

cost efficiency and scale economies in the turkish insurance industry this article examines the cost efficiency and scale economies of insurance firms in the turkish insurance industry over a 15 year period 1990 2004 using the stochastic cost frontier model cost efficiency scores and scale economies were estimated for each firm in the sample the results show that mean cost inefficiencies range between 18 3 and 36 9 of total costs and they do not tend to decrease over time on average small firms are more cost efficient than large firms economies of scale appear present and significant for any class size the results suggest that there is a substantial difference in scale economies between small and large insurance firms

identification of key sectors in the bangladesh economy a linkage analysis approach this paper purports to identify key sectors in the bangladesh economy employing the concepts of forward and backward linkages an attempt is made to rank sectors according to their employment and output potentials the paper draws a distinction between gross and net linkages defined respectively on the inverses of the leontief technology matrix and the domestic matrix using data for bangladesh it is shown that the transition from gross to net linkages implies significant divergence in sectoral rankings this appears to be true for ranking of sectors in terms of output and employment suggesting a potential conflict between employment and output generation potentials particularly in the industrial sectors when net linkages are considered agricultural sectors appear to rank high on both counts

the specification of partial static equilibrium models in conducting an investigation into the specification of partial static equilibrium factor demand models this paper isolates 1 the endogeneity of output and quasi fixed factor levels 2 the choice of omitted share equation and 3 the presence of serial correlation when using time series data as the specification issues that most affect the existing empirical literature the impact of specification changes are studied via a series of experiments conducted on an illustrative data set and are found to have significant effects on parameter estimates and model diagnostics departures between observed and full equilibrium levels of quasi fixed factors and price elasticities as a consequence caveats must be attached to several previous studies and care must be taken by future researchers in addressing using such models copyright 1987 by mit press

the measurement of efficiency in life insurance estimates of a mixed normal gamma error model abstract this paper make three contributions to the literature on efficiency in financial services first it presents estimates of a mixed error cost frontier in which the variances of both the normal and gamma distributions can vary with firm size second it extends the literature on life insurance scale and product mix economies by incorporating and measuring x inefficiency estimates of x inefficiency range from 35 to 50 ray scale economies exist up to 15 billion in assets third comparisons of normal gamma estimates with other methods 3 thick frontier weighted least squares half normal distributions 3 demonstrate some of their pitfalls

exchange rate volatility and international trading strategy abstract it is usually argued that an increase in exchange rate volatility reduces the volume of international trade as trading firms are risk averse this paper shows that exporting firms benefit under fairly general conditions from an increase in exchange rate volatility firms optimally adjust their export volumes to the level of the exchange rate exporting is an option which is exercised if profitable in addition the paper presents conditions under which the volume of international trade grows with exchange rate volatility

organization and efficiency in the international insurance industry a cross frontier analysis abstract this paper employs cross frontier analysis an innovative tool based on data envelopment analysis to provide new insight into the relationship between organization and efficiency in international insurance markets we are the first to empirically test the expense preference hypothesis and the efficient structure hypothesis in a large cross country study for this purpose we consider 23 807 firm years for 21 countries from northern america and the european union a dataset not previously analyzed in this context we find evidence for the efficient structure hypothesis in selected market segments but we find no evidence for the expense preference hypothesis our results provide insight into the competitiveness of stock and mutual insurers from different countries at the country level the results can be used to compare different insurance markets our findings are especially interesting for the strategic management of insurance companies as well as for regulators and boards of national insurance associations

the trade off between gnp and unemployment in a dual economy many developing nations frequently are reluctant to liberalize their domestic markets and or their trade regimes the effect on the distribution of income is a common rationale for avoiding the politically dangerous step of liberalization the costs to the policymaker of getting the prices right are usually associated with a depreciated capital stock specific human and physical capital and transitional unemployment the notion that urban unemployment may rise in the face of policies that one would normally judge helpful is well understood in the dual economy literature corden 6 uses the harristodaro 11 two sector dual economy model to show how an urban wage subsidy may perversely raise urban unemployment khan and chaudhuri 12 generalize this result to n rural sectors ethnic groups finally gang and gangopadhyay 10 show that under certain sets of realistic assumptions choosing a more labor intensive technique of production may aggravate urban unemployment a separate strand of the dual economy literature explores the issue of optimal policies in a dual economy harris and todaro 11 argue that a manufacturing sector wage subsidy combined with restrictions on labor migration are needed to achieve the first best competitive equilibrium in a dual economy characterized by an urban minimum wage bhagwati and srinivasan 4 elegantly demonstrate that a uniform wage subsidy would do the same job bhagwati 3 has also shown that reductions of an only distortion the urban minimum wage here are successively welfare increasing until the distortion is fully eliminated and for the harris todaro model basu 2 shows that the value of aggregate output gnp is a monotonically increasing function of the uniform wage subsidy secondary distortions related to financing the subsidy remain the primary argument against full implementation of the first best optimal wage subsidy 6 152 in this paper i use the harris todaro dual economy model to demonstrate two connected propositions although a large enough application of any first best policy a uniform wage subsidy or devaluation are but two examples must decrease urban unemployment a small one may raise unemployment 2 thus uncertainty about the appropriate sized policy can lead to

the poverty trap the dual externality model and its policy implications abstract this paper analyzes poverty traps in a monopolistic competition general equilibrium model with aggregate demand externality in our model the central hypothesis is represented by the introduction of externalities in fixed costs that firms have to incur in order to industrialize as a spillover across sectors by this we mean that the fixed cost incurred by a firm in order to start production can reduce the fixed cost that firms in other sectors of the economy must incur with such an assumption we can show the possibility for an economy to be locked in at different stages of development we then proceed to discuss the policy implications and the possible role for government intervention to this end we provide a potential framework of reference that if properly developed may be useful in policy design

technical efficiency and farm size a conditional analysis the relationship between technical efficiency and size might be affected by farm heterogeneity we analyse this relationship conditional on a set of control variables these control variables are chosen using a production model where technical efficiency is introduced as a parameter as a result technical efficiency affects both the input demand and the output supply of a profit maximising producer the empirical application explores these issues using panel data of dairy farms in spain

the search for consistency in economic search previous experimental work has discovered several high performing heuristic strategies in the search for the most economic price of a good in situations where the purchaser has partial prior knowledge of the price distribution it appeared previously however that individuals do not use a given search rule consistently this paper describes a modified experimental framework that investigates this apparent inconsistency in search behaviour results are analysed at the individual level rather than in aggregate the paper concludes that individuals do adopt consistent strategies subject to certain identified caveats it is suggested that inconsistent behaviour is associated with decision difficulty very low search costs and subjects intellectual ability moreover it concludes that the strategy most frequently adopted is fairly crude and is not the best performing one

investment under uncertainty irreversibility and the arrival of information over time in this paper we consider a risk neutral competitive firm which is uncertain about the true state of demand we build upon arrow by demonstrating that the irreversibility of investment in physical capital together with the anticipation of receiving information and of learning the state of demand lead to 1 cautious investment behaviour and hence to lower investment levels than otherwise since the firm cannot disinvest if market conditions turn out to be less favourable than currently anticipated 2 a time varying risk premium or marginal adjustment cost which is shown to arise endogenously and to be positively related to the investment level and to the anticipation of greater information in the sense of blackwell 1951 1953 3 a gradual adjustment of the capital stock to the desired level defined as the optimal capital stock corresponding to the true state of demand

the demise of the mutual organizational form an investigation of the life insurance industry we investigate the role of organizational structure in financial services markets by examining the u s life insurance industry traditionally stock and mutual life insurers were equally represented but now the industry is mainly composed of stock firms we find operational efficiency access to capital and tax savings are important determinants for this shift the incentive to demutualize differs by the type of conversion full demutualization is chosen for efficiency and access to capital reasons and partial conversion using a mutual holding company is chosen for tax savings firm operational efficiency improves after conversion we also find the efficiency of the stock organizational form dominates that of the mutual structure during our sample period 1995 to 2004

divergency between average and frontier production technologies an empirical investigation for bangladesh applied economic analysis and policy formation often relies on esttimated porduction technologies primal representations of production technologies can be specified as the average production function or as the stochastic frontier this paper uses nested and non nested specification tests and assessment of economic variables including elasticities and marginal products to evaluate systematic differences between the average production function and three different specifications of the stochastic frontier bangladesh serves as an illustrative example the importance emerges of first beginning any analysis of production technologies with nested hypothesis testing of inefficiency and non nested hypothesis testing for systematic but unknown differrences between the average and stochastic frontier functions followed by nested testing of the final form of the production technology

frontier estimation and firm specific inefficiency measures in the presence of heteroscedasticity the purpose of this article is to illustrate a straightforward and useful method for addressing the problem of heteroscedasticity in the estimation of frontiers a heteroscedastic cost frontier model is developed and estimated using bank cost data similar to that used by ferrier and lovell our results show dramatic changes in the estimated cost frontier and in the inefficiency measures when accounting for heteroscedasticity in the estimation process we find that the rankings of firms by their inefficiency measures is affected markedly by the correction for heteroscedasticity but not by alternative distributional assumptions about the one sided error term

an east asian model of economic development japan taiwan and south korea the east asian model of economic development focuses on 5 shared characteristics that seem significant in the contemporary economic development of japan taiwan and korea they are economic characteristics and include 1 high investment ratios 2 small public sectors 3 competitive labor markets 4 export expansion and 5 government intervention in the economy large and efficient investments in human capital and well developed capacities to absorb new technology are 2 other economic features shared by the three one could add overcrowding high man land ratios and scarcity of natural resources though these are handicaps rather than sources of economic strength it is possible however that virtue springs from necessity and that ample arable land or abundant natural resources mainly permit governments to postpone the difficult decisions needed to promote development rather than provide the wherewithal needed to finance development other noneconomic characteristics of the three such as ethnic and linguistic homogeneity relatively compact geography manageable population size and the confucian tradition have not been considered in the model even though they have undoubtedly influenced labor productivity savings behavior and other aspects of economic performance whether the east asian model ought to be followed depends on whether current and foreseeable circumstances are sufficiently like those faced by the three to justify using the same policies that they used applicability of the east asian model should also depend on whether the strategy employed by the three has been responsible for their economic success 2 aspects of the east asian models policy features are noteworthy 1 the policies typically work by influencing rather than replacing private market decisions and 2 the public expects government to intervene to influence economic growth

the use of input output analysis to determine the appropriateness of technology and industries evidence from bangladesh since the proportion of available capital to labor is low in ldcs compared to the developed countries the most appropriate techniques for ldcs from an economic point of view are likely to be the laborintensive ones if we suppose that there is a single most efficient technique for each industry and if it technologically requires labor and capital in fixed proportions the most appropriate industries for ldcs are likely to be the labor intensive ones this is because of the close correspondence between industries and their technological requirements on an international scale this appropriateness is given some support by the heckscher ohlin theorem of international specialization in production as is well known this theorem indicates subject to various assusmptions that countries should specialize in the production of goods that make use of their relatively abundant factors of production the aim of this paper is to identify appropriate industries for bangladesh in view of the relative availability of labor and capital and taking into account the amount of labor and capital needed both directly and indirectly to produce output for each industry unfortunately as specified below a number of previous studies of appropriate techniques and industries have ignored the indirect requirements for labor and capital needed to produce the various intermediate products used in these industries interindustry analysis based on the assumption that the adopted techniques require inputs to be combined in fixed

nominal and real volatility as determinants of fdi this article examines the role of country specific sources of output and interest rate or exchange rate volatility in driving foreign direct investment fdi activities building on a dataset with bilateral fdi flows among 24 organization for economic co operation and development oecd economies over the period 1985 2007 we find that nominal and real volatility strongly deter foreign investments output and exchange rate volatility matter in particular for the decision whether to invest in a foreign country in the first place interest rate volatility mainly influences the amount of foreign investments

production technology elasticity of substitution and technical efficiency of the handloom textile industry of bangladesh a number of translog and cobb douglas frontier production models were estimated for the bangladesh handloom textile industry to investigate its production technology and technical efficiency in production it was found that the technical efficiency of the industry in producing cloth was only 41 it was concluded that the industry might improve its technical efficiency by increasing its male female labour ratio and yarn capital ratio and decreasing its hired family labour ratio and labour capital ratio the production technology of the industry was found to be characterized by a linearly homogeneous cobb douglas function the elasticity of substitution between labour and capital for the industry was found to be unity

sectoral balance in development a survey abstract this paper surveys the literature on sectoral balance to see how sectoral imbalances can retard economic development it examines definitions of sectors and balance provides background facts theories and planning tools reviews the debate on balanced growth and surveys two sector models of agriculture industry consumption investment and luxury basics interaction the open economy and the role of service nonmarket and unproductive sectors it argues that the examination of important development issues requires multisectoral analysis incorporating the insights of several of these models and that alternative models with different structural characteristics deserve attention

the impact of yuan internationalization on the stability of the international monetary system we study the implication of yuan internationalization on the stability of the international monetary system more specifically we use a three country three currency portfolio model to analyze the impact of yuan internationalization on exchange rates in the event of trade shocks with stock flow adjustment of the net foreign asset positions we show that the internationalization of the yuan would lessen the response of floating exchange rates to asymmetric trade shocks as well as attenuate the distortionary impact of china keeping its currency pegged to the dollar conversely yuan internationalization would amplify the impact of trade shocks on net foreign asset positions albeit to a limited extent

x efficiency in the us life insurance industry abstract using six years of data 1985 1990 we estimate hybrid translog cost functions for 561 life insurers we examine the resulting residuals to determine the relative efficiency of insurers in the sample we then test the residuals to see if they are related to so called x efficiencies because of internal and external monitoring or to other factors related to rent seeking results show a large degree of persistent inefficiency seems to exist among sample firms the inefficiencies relate to some internal or external monitoring and rent seeking may be occurring

increasing returns and the foundations of unemployment theory current approaches to macroeconomic theory divide roughly into two basic schools of thought one approach typically associated with rational expectations views the economy as basically at or near walrasian market clearing equilibrium in which case it becomes very difficult to explain away convincingly the undeniable persistence at times of involuntary unemployment another approach views the underemployed economy as being in a state of temporary fixed price disequilibrium in which case aside from having to repress suspicions that the essence of effective demand failure might not have to do with prices fixed at wrong values there is a lot of rationalising to be done about why profitable adjustments are so slow this paper argues that something like an internally consistent theory of steady state involuntary unemployment is possible and even plausible the cornerstone of this third approach is increasing returns to scale which blocks unemployed agents from breaking out of a low level equilibrium trap unless there is overall coordination or stimulation a simple model is presented which contains the basic ideas

the coexistence of distribution systems under price search theory and some evidence from insurance abstract this paper analyzes a pure price search model of an insurance market in which two different search technologies are simultaneously available sequential search and nonsequential search sequential search characterizes firms that sell directly to consumers and nonsequential search characterizes firms who use independent agents that sell the products of a number of different firms the separation of firms and consumers into the two market sectors is endogenously determined and the conditions for equilibrium coexistence are derived the characteristics of price distributions in the two sectors are then compared in a coexistence equilibrium price distributions observed in automobile insurance markets are found to be consistent with the predictions of the theoretical model

the effects of exchange rate variability on international trade a meta regression analysis the trade effects of exchange rate variability have been an issue in international economics for the past 30 years the contribution of this article is to apply meta regression analysis mra to the empirical literature on average exchange rate variability exerts a negative effect on international trade yet mra confirms the view that this result is highly conditional by identifying factors that help to explain why estimated trade effects vary from significantly negative to significantly positive mra evidence on the pronounced heterogeneity of the empirical findings may be instructive for policy first by establishing that average trade effects are not sufficiently robust to generalize across countries and second by suggesting the importance of hedging opportunities hence of financial development for trade promotion for the practice of mra we make a case for checking the robustness of results with respect to estimation technique model specification and sample

economics of development and the development of economics the purpose of this paper is to restore some historical perspective by highlighting the many contributions of development economics to the rest of economics we will point out to the younger generations how some of the glittering ideas they currently play with originally came from that now neglected field and how in some cases they have rediscovered with great fanfare insights that were well known in the development literature familiarity with which would have enriched their own work
