Abstract

Since its introduction by Chari, Kehoe, and McGrattan (2007), Business Cycle Accounting (BCA) exercises have become widespread. Much attention has been devoted to the results of such exercises and to methodological departures from the baseline methodology. Little attention has been paid to identification issues within these classes of models. In this chapter, the authors investigate whether such issues are of concern in the original methodology and in an extension proposed by Šustek (2011) called Monetary Business Cycle Accounting. The authors resort to two types of identification tests in population. One concerns strict identification as theorized by Komunjer and Ng (2011) while the other deals both with strict and weak identification as in Iskrev (2010). Most importantly, the authors explore the extent to which these weak identification problems affect the main economic takeaways and find that the identification deficiencies are not relevant for the standard BCA model. Finally, the authors compute some statistics of interest to practitioners of the BCA methodology.

Abstract

Purpose

The purpose of this paper is to measure TFP growth and job reallocation in the Vietnamese manufacturing industry after the Doimoi period.

Design/methodology/approach

The study uses firm-level panel data from Vietnam’s annual enterprise survey data for 2000–2016 period in the Vietnamese manufacturing industry using Olley–Pakes static and dynamic productivity decomposition methods.

Findings

The aggregate productivity estimated from the WRDG method increased 2.323 percent, of which over 40 percent is due to the reallocation toward more productive firms. Olley–Pakes dynamic decomposition according to ownership, scale and industry shows that the contribution of private and state-owned firms and the contribution of small and medium firms and large firms to the TFP growth are 133, −33 percent, 58.56 and 41.44 percent, respectively. The within-firm productivity and net entry components are the main reasons for TFP growth rather than reallocation. The results show that the composition of the aggregate TFPs, estimated from WRDG, OP, LP and ACF, is correlated very high (over 80 percent) except for net entry components.

Research limitations/implications

The major limitation of this study is that the authors compute an aggregate productivity index using actual employment-based shares (still misallocation in labor), rather than optimal employment-based shares (no misallocation in labor).

Originality/value

Job reallocation between industries is attracting attention in developing countries, especially transition economies. However, knowledge about job reallocation among industries is limited. This paper assesses the level of job reallocation among private and state-owned firms, small and medium firms and large firms in Vietnam.

Abstract

Purpose

This article focuses on the assessment of entrepreneurship competence by selected vocational teachers in Italy. The exploratory research question addresses the extent to which entrepreneurship assessments are competence based, and the research seeks to identify fully fledged assessment programmes with both a formative and summative component, and the use of assessment rubrics. It also explores the extent to which entrepreneurship competence is referred to in school documentation and later assessed, and the tools and strategies used for such assessment.

Design/methodology/approach

This case study is part of a larger European research project promoted by Cedefop; in Italy it focused on six selected vocational IVET and CVET programmes and apprenticeship schemes. It used a wide range of instruments to ensure triangulation and multiple perspectives: analysed policy documents and undertook online interviews with experts and policy makers. At VET providers' premises it deployed: analysis of school documents; observations of learning environments; interviews and focus groups with (in schools) teachers, directors and vice directors, learners and alumni (in companies) instructors, company tutors and employers, apprentices and alumni.

Findings

Assessment tasks were rarely embedded within fully fledged assessment programmes involving both formative and summative tasks, and assessment rubric for grading. Most of the time, entrepreneurship programmes lacked self-assessment, peer assessment and structured feedback and did not involve learners in the assessment process. Some instructors coached the students, but undertook no clear formative assessment. These findings suggest institutions have a testing culture with regard to assessment, at the level of both policy and practice. In most cases, entrepreneurship competence was not directly assessed, and learning outcomes were only loosely related to entrepreneurship.

Research limitations/implications

One limitation concerned the selection of the VET providers: these were chosen not on a casual basis, but because they ran programmes that were relevant to the development of entrepreneurship competence.

Practical implications

At the policy level, there is a need for new guidelines on competence development and assessment in VET, guidelines that are more aligned with educational research on competence development. To ensure the development of entrepreneurship competence, educators need in-service training and a community of practice.

Originality/value

So far, the literature has concentrated on entrepreneurship education at the tertiary level. Little is known about how VET instructors assess entrepreneurship competence. This study updates the picture of policy and practice in Italy, illustrating how entrepreneurship competence is developed in selected IVET and CVET programmes and apprenticeships.

This paper seeks to analyze consumer preferences toward fresh rabbit meat and obstacles and interest in consuming the product.

Abstract

Purpose

This paper seeks to analyze consumer preferences toward fresh rabbit meat and obstacles and interest in consuming the product.

Design/methodology/approach

The paper uses the dual response choice experiment (DRCE) design which allows for analyzing forced and unforced options in choice experiments using the same sample. The heteroscedastic extreme‐value (HEV) model is used due to its relaxation of the restrictive assumption made in the multinomial logit model regarding the identically distributed error term across alternatives. The empirical analysis uses consumer‐level questionnaires to elicit information regarding consumer attitudes toward rabbit meat in Catalonia (Spain).

Findings

The results demonstrate a higher preference for rabbit meat from “Catalan” origin followed by higher quality certification information. Convenience and “ready‐to‐eat” products made from rabbit meat may help bolster increased consumption. An effective communication campaign is needed to educate individuals regarding the health characteristics of rabbit compared to other types of meat. Furthermore, results demonstrate that the ordering of attributes is not significantly different from forced and non‐forced choices obtained from the DRCE design. However, significant differences on the magnitude of the preferences for some attributes' levels are found.

Research limitations/implications

From a methodological point‐of‐view, the study follows a similar design to the dual response choice experiments. However, the study is differentiated by asking consumers whether they are willing to buy the product. More emphasis is made on the purchasing context of the task leading consumers to focus more on their budget constraints by considering the price. The study uses the DRCE design as an alternative of the traditional single stage choice experiments. Owing to budgets constraint, the study could be improved by comparing results from both designs. At the empirical level, it would be interesting to extend the study to other geographical parts in Spain.

Social implications

The study can help policy makers in stimulating demand for rabbit meat. Rabbit meat farmers in Catalonia were forced to abandon their farms due to the lack of demand. Consumption has decreased dramatically. As recommended in the paper, high quality labelling of the meat, improving the carcass format and its presentation and the healthiest characteristic of the meat could be a good way to promote and stimulate demand.

Originality/value

From the empirical point‐of‐view, this study, to the authors' knowledge, is the first application of CE and CV to analyze consumers' preferences towards rabbit meat. Furthermore, it is the first paper that applies the HEV model in agro‐food economics and specifically towards rabbit meat.

Abstract

Purpose

Important socioeconomic changes have been undergone due to the international economic crisis. In Catalonia (Spain), political changes towards independentism also occurred within the same period. The purpose of this paper is to explore the consumers’ wine preferences in Catalonia in two different scenarios. In particular, the authors have focussed the interest in those preferences regarding the regional origin of the wine.

Design/methodology/approach

Data were elicited from two identical discrete choice experiments performed in two times: before (2008) and during the economic crisis (2010) in Catalonia, Spain.

Findings

The results imply that the external common circumstances may have had a homogenising influence in consumer choices by decreasing the level of randomness of consumers’ selection. Consumers’ preferences for a Catalan origin were enhanced during the crisis, while price became the most important attribute.

Research limitations/implications

Ideally, the participants involved in both experiments would have been the same. Unfortunately, this was not possible to maintain and it is one of the limitations of this study. The authors are also aware that other non-controlled variables may have also played a role and the conclusions that are driven should be taken carefully.

Originality/value

This paper contributes to the literature of the discrete choice modelling using the recently developed Generalized Multinomial Logit Model. To the knowledge this is the first application in the literature of wine preferences to measure the impact of the contextual changes (economic and political) in Catalonia (Spain).

Abstract

The global slack hypothesis is central to the discussion of the trade-offs that monetary policy faces in an increasingly more integrated world. The workhorse New Open Economy Macro (NOEM) model of Martínez-García and Wynne (2010), which fleshes out this hypothesis, shows how expected future local inflation and global slack affect current local inflation. In this chapter, I propose the use of the orthogonalization method of Aoki (1981) and Fukuda (1993) on the workhorse NOEM model to further decompose local inflation into a global component and an inflation differential component. I find that the log-linearized rational expectations model of Martínez-García and Wynne (2010) can be solved with two separate subsystems to describe each of these two components of inflation.

I estimate the full NOEM model with Bayesian techniques using data for the United States and an aggregate of its 38 largest trading partners from 1980Q1 until 2011Q4. The Bayesian estimation recognizes the parameter uncertainty surrounding the model and calls on the data (inflation and output) to discipline the parameterization. My findings show that the strength of the international spillovers through trade – even in the absence of common shocks – is reflected in the response of global inflation and is incorporated into local inflation dynamics. Furthermore, I find that key features of the economy can have different impacts on global and local inflation – in particular, I show that the parameters that determine the import share and the price-elasticity of trade matter in explaining the inflation differential component but not the global component of inflation.

Abstract

Purpose

This paper aims to present a novel approach on investigating critical current densities in the solder joints of chip-size surface-mounted components or device (SMD) components and ball grid array (BGA) lead-free solder joints with the focus of via-in-pad geometries. The investigation involves a numerical approach and a physical validation with selected geometry configurations and high current loads to reveal possible failure sources. The work is a continuation of a previous study.

Design/methodology/approach

Current density was investigated using finite element modeling on BGA joints. Dummy BGA components, 0402 and 0603 zero ohm jumper resistors, were used, both in daisy chain setups on standard FR4 printed circuit boards (PCBs). Respective physical loading experiments were set to find effects of elevated current density at hot zones of the joints. Cross-section analysis, scanning electron microscopy and shear force tests were used to analyze the joints.

Findings

The findings reveal alterations in the joints, while the current loading is not directly affecting the structure. The modeling reveals the current density map in the selected formations with increased current crowding zones. Overall, the degradation does not reach the level of electromigration (EM)-induced voiding due to the limiting factor of the FR4 substrate.

Practical implications

The heavy current load affects joint reliability, but there are limitations of EM-induced failures on PCB-based assemblies due to the thermomechanical weakness of the FR4 material.

Originality/value

The experiments investigate current density from a novel aspect on frequently used BGA surface mounted components with modeling configurations focusing on possible effects of via-in-pad structure.

Abstract

Purpose

The purpose of this paper is to present a holistic intra‐individual perspective on leaders, which focuses on four components of the inner person of the leader; Being, Cognition, Spirituality, and Emotion, and on the observable components of Behavior and Relationships.

Design/methodology/approach

Existing leadership literature is appraised within the context of the model. Previously‐proposed interrelationships among the components are enumerated. The paper suggests implications of the model regarding research content and methodology as well as leader development.

Findings

The model implies that all components should be included in research and that interrelationships among components should be explored. Also implied is the use of methodological pluralism.

Practical implications

Leaders should attend to all components in the model in their self‐development efforts.

Originality/value

The paper takes an unusual approach to understanding leadership: an individual‐level holistic perspective.

Abstract

Purpose

This study is based on the development of predictive classification for the success of a venture capital (VC) deal derived from both qualitative and quantitative indicators.

Design/methodology/approach

Decision tree analysis has used for devising the success model of VC deal. Various deal characteristics are considered in this study as the observable component of success.

Findings

The finding of this analysis indicates that the success of the deal does not only depend on the final outcome like post company valuation (POST_COMP), realised revenue (RREV) but also depends on various observable contractual characteristics like syndication, use of convertible security and ownership percentage with some noticeable deal features.

Practical implications

This study increases the further scope of study on a contractual mechanisms such as allocation of cash flow right and control right in the deal contract between venture investor and entrepreneur firm. This could give a better understanding of success path of a venture deal.

Originality/value

This study has attempted to derive a performance model based on observable attributes of a VC deal.
