The behaviour of the US consumer price index 1913–2003: a study of seasonality in the monthly US CPI

This article analyses the seasonality in the monthly consumer price index (CPI) over the period January 1913 to December 2003. We examine three types of month effects: if the mean of monthly CPI changes of the entire data set, and of a given month were significantly different from zero; if the mean of monthly CPI changes of a given month was different from the mean of the other months; and if the variance of the monthly CPI changes for a given month was different from the variance of the other months. The mean of monthly CPI changes for the entire data set (0.27%) was found to be significantly greater than zero. The means of monthly changes show a downward trend from September to December. When the data are sliced into three sub-periods, we find an increasing trend in the means and medians of monthly changes but a decreasing trend in the SDs of the monthly changes. The mean of monthly CPI changes during the republican presidencies (0.15%) was significantly lower than during the democratic presidencies (0.38%).     

Effects of packers’ inventory and market power on price adjustments in the U.S. beef industry

This study examines effects of packers’ inventory and market power on their price adjustment behaviour in the U.S. beef industry. Econometric model used in the study allows inventory and market power variables to influence the speed-of-adjustment parameters in a three-regime threshold error-correction model. Results show that the two variables have a statistically significant impact on packers’ price adjustment behaviour when price decreases but not when price increases. When price decreases, inventory tends to accelerate the adjustment process whereas packers’ market power slows down the adjustment process. The hypothesis of symmetric adjustment towards long-run equilibrium during increasing and decreasing phases of price is not rejected when the effects of inventory and market power are considered in explaining packers’ price adjustment behaviour. However, when these two effects are ignored in the model specification, the hypothesis of symmetry is rejected such that the speed of adjustment in the increasing phase of price is faster than the adjustment speed in the decreasing phase of price, i.e. ‘rockets and feathers’ effect.     

What explains the performance of students in a heterogeneous environment? Conditional efficiency estimation with continuous and discrete environmental variables

Efficiency estimations which do not account for the operational environment where production units are operating in may have only a limited value. This article presents a fully nonparametric framework to estimate relative performance of production units when accounting for continuous and discrete background variables. Using insights from recent developments in nonparametric econometrics, we show how conditional efficiency scores can be estimated using a tailored mixed kernel function with a data-driven bandwidth selection. The methodology is applied to the sample of Dutch pupils from the Organization for Economic Co-operation and Development's Programme for International Student Assessment (OECD PISA) data set. We estimate students' performance and the influence of its background characteristics. The results of our application show that several family- and student-specific characteristics have a statistically significant effect on the educational efficiency, while school-level variables do not have impact on performance.     

Does the law of one price hold in a high-inflation environment? A tale of two cities in Turkey

This study addresses the price convergence in two cities in Turkey (Istanbul and Ankara) using annual data over the three-quarters of the twentieth century (1922–1998), characterized by prevailing high inflation rates for most of the period. In contrast to the rest of the literature addressing convergence in price levels with a typical result of extremely slow convergence rates at best, we argue that convergence is much easier detected in growth rates rather than levels of prices. We suggest using the bounds testing procedure of Pesaran et al. (2001) for this purpose. We find a clear-cut evidence on the existence of a common driving force behind inflation dynamics in Istanbul and Ankara – a finding that is in contrast with the results typically reported in related literature.     

On the development strategy of countries of intermediate size—An analysis of heterogeneous firms in a multi-region framework

This paper compares two policies: trade cost reduction and firm relocation cost reduction using a three-country version of a heterogeneous-firms geography and trade model, where the three countries have different market (population) sizes. We show how the effects of the two policies differ, in particular for the country of intermediate size. Unless the intermediate country is very small, in a relative sense, it will gain industry when relocation costs are reduced, but lose industry when trade costs are reduced. The smallest country loses industry in both cases, but only experiences lower welfare in the case of lower relocation costs. Thus, the ranking of the policies from the point of view of the two small and intermediate countries tends to be the opposite.     

The effect of rural labor migration on poverty alleviation： a viilage-level study in China

The construction of the new socialist countryside is being carried out in China nowadays. Although lots of successful experience has been gotten, different problems occur in various regions yet. To analyze the relationships among rural labor migration, poverty alleviation and characteristics of migrants is important in considering the effect of rural labor migration on the construction of the new. socialist countryside, Available sampling and typical case study are adopted and 236 questionnaires are collected from four villages in northwest GuangxL China, Daxin, Lixin, Longhe and Yongehang, We analyze the rural labor migration status, characteristics of migrants, remittance situation and income, household income and the ratio of remittance income to total household income. About 2/3 of the households have migrants in surveyed villages. And nearly half of the migration households have only one family member as migrants in the four villages. The migrants mainly comprise male and the younger, with the education level of junior middle school and higher More than half of the migrants are employed in Guangdong Province. But the characteristics of migrants in Yongchang are more diverse. The rural labor migration in the village is extremely active and extensive. And over 60% of the household with family members as migrants have remittance income. The rate in Yongchang is extremely high （80%）, And the income of households with migrants getting remittance income is significantly higher than their counterparts. More than half of their income comes from remittance as far as the former kind of household is concerned And in Yongchang, the rate is nearly 80%. The conclusion is that rural labor migration is popular and extensive in lots of villages. And the migration and remittance play an important role in rural household income, especially in some poor villages. For this kind of village, the rural labor migration may be some ＂compulsory course＂ in rural development. And the rural labor emigration is an essential way in     

The burden of blood transfusion: a utilization and economic analysis – a pilot study in patients with chemotherapy-induced anemia (CIA)

Abstract

Objective:

The objective is to measure the burden of blood transfusion of Packed Red Blood Cells (PRBCs) in patients with chemotherapy-induced anemia (CIA) on the institutional outpatient transfusion center.

Methods:

This is a retrospective chart review (starting July 1, 2010, working backwards until 120 evaluable patients are accrued) at a single institutional transfusion center in the US. The mean and standard deviation (SD) were calculated for patient’s age, pre-transfusion Hgb level, and other transfusion-related activities.

Results:

One hundred and twenty records were reviewed. The majority included patients who were female (71%), African American (61%), and had either Medicare (48%) or private insurance (39%). The mean patient age was 59 years and the average pre-transfusion Hgb was 7.9?g/dL. The average patient visit to facility ranged from 213?min for one PRBC unit to 411 minutes for three PRBC units. The mean staff time for patient evaluation was 66 minutes. Actual time for transfusion was ～100?min for each PRBC unit; 90% of patients received two PRBC units. Staff was engaged in direct patient care for an average of 322?min for two PRBC units. The labor cost of transfusion (in 2011 $US) ranged from $46.13–$49.33 per PRBC unit. The estimated fully loaded bundled cost was $596.49 for transfusion of one unit of PRBC. Limitations of the study include: the site included in this study may not be applicable to all sites in practice and the evaluated patient population was varied, with the exception that all patients were treated for some type of malignancy; and the review of blood bank records for 120 patients was not 120 independent events and, as such, may not have adequately captured actual variability.

Conclusions:

This analysis quantifies expense in terms of time for administration of the transfusion, as well as costs associated with outpatient blood transfusions.     

Simulation Analysis of Public Debt and Fiscal Deficit in Austria – Optimal Economic Policies for the Past and the Future

The macroeconometric simulation model AMOD1 and the optimization algorithm OPTCON are used to evaluate fiscal policies for Austria since the late seventies. In particular, the question of optimal (debt stabilizing) fiscal policies for the past and for the future is analyzed within the framework of a medium-scaled simulation model. The first set of optimization experiments aims to assess optimal fiscal policies for debt stabilization for the historical period 1978–2000 while trying to maintain reasonable growth rates of approximately 2 percent of real GDP. Optimal values of the instruments and the targets are compared to empirical data for Austria. A second set of simulations calculates optimal paths for the fiscal instruments for the period 2001-2010, particularly with respect to the criteria of the Stability and Growth Pact, which is mandatory for member states of the Euro zone.     

Strategic intent and the strategic position of smallholders: a case study of a smallholders’ organization in the Ghanaian cocoa industry

Abstract

Despite their clear relevance in western business society, many strategic management literature insights are neglected in the development debate regarding smallholders in third world countries. This article explores if strategic intent may be a useful tool in the smallholder debate, by conducting a case study of a smallholders’ organization in the Ghanaian cocoa industry. The case study shows that the strategic intent of the smallholders’ organization and the commitment of its members are inadequate. Group goals are lacking, farmers are participating in side-selling, and do not actively engage in the cooperative. These problems may be resolved by propositions provided by the strategic management literature, such as the introduction of an entrance fee to participate in the cooperative.

Development pattern of the industry form in mountains area： a case study of the Three Gorges Reservoir area

The mountainous areas （mountain, plateau and hilly area ） cover than 85% of total land territory of China.Nature and humanity in very mountainous ares has its own geographic characteristics.In the process of industrialization and urbanization in China, realizing the sustainable development of the mouniainous areas, optimizing man-land system, and adopting and continuously developing corresponding economic modes of the mountainous areas with multi-functions of economy, ecalogy, culture and society to chararacterize production content, mode of production. mode of operation is not only helpful to econonty, society and ecological value and is of great aesthetic value,but also solve the technological problems of the subject of starting undertaking to finally transform the regional resource advantage of the mountainous area into the advantage of capital and technology for economic development and to get rid of the contradiction between underdeveloped economy and abundant resources. This paper takes the Three Gorges Reservoir（TGR） area for example to show that it＇s of great practical and theoretical significance ,regional distribution,variety structure and quality structure.     

Strategic planning of optimal resource allocation in response to global financial crisis – a study of international tourist hotels

This study is principally designed to examine the changes in the efficiency, effective resource allocation and future operation strategies of Taiwan's international tourist hotel in global economic downturn. At first, we set up critical input and output factors and construct an assessment model using Data Envelopment Analysis (DEA) for analysis of relative efficiency. Further, we apply an allocative efficiency model for additional considerations of each input cost and analyse proper and effective resource allocation. Finally, there are significant changes in overall efficiency of international tourist hotels under global financial crisis. We can also reach an effective allocation of the overall resources. In such cases, lowering cost has become a key issue for sustainable operation of international tourist hotel. Finally, the greatest contribution of this study is to further classify the competitiveness and optimal cost allocation of Taiwan's international tourist hotels into seven categories based on the study results and propose strategic planning of future operations for hotel administrators’ reference in making improvements in the future.     

Assessment of the immigration effect and choice of development pattern for scenic areas： a case study of Wuyi Mountain, China

Mountainous regions face a series of Conflicts betWeen the natural resources conservation and the economic development, especially in protected areas, where are the home to some of the poorest people in＇the world In China, the Protected Areas Authorities （such as Protected Areas Authorities of Wuyi Mountain） transferred the mountainous people out of the protected areas. We found that it is not a good approach of immigration project, as fal economic and ecological effect is concerned. Although remote and majestic, beauty attracted many tourists, mass tourism is not a good approach to soh,e the development problem in mountainous areas because it can not provide enough opportunites to make local people live a comfortable life, and the high volume of tourists indicates that the resources, face significant threats. Because many fandscapes,are run by Private enterprises, local residents and government only get limited benefits. Alihough ecotourism principles expatiate on economic development and resource, onservation, local people income and tourists feelings, it has discordance between the theory and the praciice Therefore. the term of ＂integrated ecotourism ＂ was coined in the paper.based on the ecotourism theory, Integrated ecotourism means a broadly tourism resources and pendulum spatial pattern which will come into being with the movement of local,people and tourists from protected areas io the nearby town or city： and it also tries to solve the property right conflict of mountain land between the local people and the private enterprises according to property right theory.     

Industrial structure and preferences for a common currency – the case of the EURO referendum in Sweden

Attitudes for a common currency differ from nation to nation, or from region to region. We analyse regionally differing voting results of a referendum held in Sweden in lieu of joining the European Monetary Union. We put a special focus on the role of the industrial mix – being a potential factor influencing heterogeneous transmission – and find a significant, but subordinated, impact on voting behaviour.     

Estimation of the value of the marginal product of emission in a country where emissions output is regulated — an empirical study

Emissions resulting from the production process can be characterized as use of the elimination and disposal services of the ecological system. Hence, they are use of natural resources and thus an input to production. The present paper discusses an approach to evaluate the returns of these kind of services as a production factor.First, four main types of industrial emission are chosen —SO ₂,CO ₂,NO _xandparticulate matter — and integrated in a Cobb-Douglas production function. With this approach, the production elasticities and the marginal product of these types of emission can be estimated.Based on these results and assuming that marginal product equals price, the demand curve for emission is estimated. With this demand curve the consequences of different kinds of environmental policy are considered. Under further assumptions of optimal behaviour it can be shown that the demand curve for emission is equal to the curve of marginal costs of avoidance (MCA). Thus, the estimates of the demand curves can be considered as estimates of the MCA-curves. Furthermore the price elasticities of these four types of emission are estimated with this approach. The method used in the paper is suggested for calibration of CGE models.     

Non-uniformity of job-matching in a transition economy – A nonparametric analysis for the Czech Republic

This study explores the properties and development of the matching technology in the Czech Republic during the transition to a market economy. Nonparametric additive modelling allows us to assess flexible functional forms, which comprise for instance CES and trans-log specifications. This enables us to evaluate the matching process locally for each combination of unemployment and vacancies rather than being restricted to global coefficients. Special interest is devoted to analysis and economic determinants of regional variation in the returns to scale of the matching function. Non-linearities are found in the partial adjustment process of unemployment outflows, and a negative coefficient on vacancies in some years. Moreover, increasing returns to scale in job-matching are found locally. Returns to scale are found to be negatively correlated to the share in employment in services and to outmigration, positively correlated to the employment share in industry, the unemployment rate and various measures of active labour market policies.
