In an inventory model with exogenous sales, FIFO and LIFO criteria are formalized and compared with national account estimates for intermediate and finished good products. The model is simulated by utilizing manufacturing input and output prices for Italy (1970–88). LIFO and national account estimates of inventory are usually close and also imply reliable measures of output level and changes which can be shown by solving the quantity model. Conversely, FIFO exhibits larger profits and leads in real terms to unsatisfactory estimates of output changes.  相似文献

In questo lavoro si introducono cinque nuove classi di funzioni concave generalizzate; di esse si studiano le proprietà e le interrelazioni con le classi più note in letteratura. Più precisamente, dopo aver evidenziato che le nuove classi sono distinte tra loro e da quelle già note in letteratura, se ne analizzano organicamente le differenze e si studia il loro comportamento dapprima in ipotesi di semicontinuità superiore e poi in ipotesi di continuità. Nel lavoro si dimostra inoltre il mantenimento di alcune proprietà strutturali come pure la conservazione delle principali proprietà relative all'ottimizzazione.
Summary In this paper five new classes of generalized-concave functions are introduced and studied. In particular, it is firstly pointed out that the new classes are different from the known ones, then their relationships are stressed both in general and under hypothesis of upper semicontinuity and continuity.Also some properties about optimization and functions transformation are provided.

The expression “the bell curve” designs both a kind of statistical distribution and the title of a famous and controversial book by Herrnstein and Murray. The first is so attractive that the second refers to it to give more credibility to its questionable theories on intelligence. The point is that, during the 20th century, the bell curve has assumed a more and more important role in psychological research and practice and have become both a reality and a myth. In the first case (reality) we can assist to appropriate applications of a real useful statistical concept. In the second (myth) we can have two kinds of attitudes: one attitude is typical of those researchers who search for normality in all their data and variables, just as Parsifal used to search for the Holy Graal (we call this “the Parsifal attitude”); the other is typical of those researchers who give normality for granted and act as if it were a Platonic Idea (we call this “the Plato attitude”). The article discusses the role of the normal distribution in psychological research and practice and shows how it can be dangerous to treat the bell curve as a God or an Idol.  相似文献

Contingent valuation studies are often characterized by a considerable number of protest responses, which may cause selectivity bias on the final estimates for WTP. Sample selection models can detect and – if necessary – correct selectivity bias. In economic applications where the relevant dependent variable is continuous, sample selection models are generally estimated using Heckman's 2-step method rather than the FIML estimator. Either method has its own drawback: computational complexity for the FIML method, susceptibility to collinearity problems for the 2-step method. Using data on valuation of forest resources for recreational use, we analyse the performance of the two estimators. In this application, given the presence of some collinearity, the FIML is preferred to the 2-step method. A procedure is outlined to deal with selectivity problems in similar settings.  相似文献

This study investigates the usefulness of an Australian accounting work‐readiness program as perceived by international accounting graduates. Using logistic regression, the study reports the results of a survey of 186 graduates who completed the program in the period 2010–2013 and are now employed in either accounting or non‐accounting roles. The results show that graduates who were employed in an accounting role perceived internships and critical thinking skills to be the most useful curriculum components of the work‐readiness program in obtaining their employment. The findings have implications for various stakeholders, in particular educators and professional bodies involved in the curriculum design of the work‐readiness program. The government also has an interest in the value of this program as they grant visas for international students to study in Australia and fill a skills shortage in the profession. The results also provide insights for other Western economies that attract large numbers of international graduates as skilled migrants.  相似文献

The BRICS countries in general, and China and India in particular, are now widely regarded as the areas of the world likely to challenge the economic leadership of the United States (US) and the European Union (EU). A large part of this challenge will come from rapid technological catch‐up by China and India. Yet, despite a recent rise in interest, there is limited knowledge about how and where innovation takes place in these two leading emerging countries and to what extent the Chinese and Indian territorial systems of innovation differ from those in the EU or the US. In this article we explore the geography of innovation in China and India, concentrating on understanding key territorial‐level innovation trends by country, region and technology field, using the US and the EU as benchmarks. We find significant contrasts between the geography of innovation in China and India and that of the US and the EU. First, the degree of concentration of innovative activities in both countries is extremely high. Levels of agglomeration of innovation in the coastal provinces of China, as well as in Delhi and the South of India, significantly exceed the levels of agglomeration found in the USA and the EU. Secondly, China has witnessed a more rapid increase in the degree of concentration of innovation than India. We posit that the differences in the geography of innovation between, on the one hand, China and India and, on the other hand, between these countries and the developed world are rooted in different institutional settings, different systems of innovation and different national innovation strategies.  相似文献
