In the practice of venture capital investment, the venture capital will not only claim the share of the enterprise’s future output, but also a certain amount of fixed income. The purpose of this paper is to examine the optimal contract which blends the variable ownership income and the fixed income theoretically so as to provide a keen insight into the venture capital practice.

This paper establishes an extended principal-agent model and researches on the design of optimal contract dominated by venture capital with double-sided moral hazard and information screening.

By establishing theoretical models, the main findings are: first, high-quality enterprise tends to relinquish less ownership but give more fixed return to the venture capital as compensation in order to obtain the venture capital financing; second, low-quality enterprise is willing to relinquish more ownership but give less fixed return to the venture capital for financing; third, due to the existence of double-sided moral hazard, neither of the venture capital and the enterprise will exert their best effort.

This paper furthers the application of principal-agent model in the field of venture capital investment and researches on the optimal contract, considering double-sided moral hazard and adverse selection at the same time originally.

The service industry has become an important sector for the economic growth, particularly in developing countries. In this context, the aim of this article is to compare the productivity determinants across firms operating in low and high knowledge intensity service sectors (low knowledge intensive sectors (LKIS) and high knowledge intensive sectors (HKIS)) in Ecuador.

The authors use a two-step estimation method. The firm productivity is estimated in the first step and the productivity determinants in the second step. To achieve the objective, the authors use an unbalanced panel database on the financial statements from formal Ecuadorian firms for the period 2007–2018.

The authors’ results show that LKIS firms are slightly more labor-intensive compared to HKIS firms. Productivity determinants are similar across HKIS and LKIS firms, except for exports and market concentration. HKIS firms are more productive when the competition level is low, indicating that higher market power is associated with higher productivity. The influence of taxes on productivity depends on firm size. Small and medium-sized firms are more negatively affected than large firms.

Taxes should be designed considering the size of the companies, since these could affect their productivity. Thus, lower taxes to small and medium firms may reduce firm size inequality. In addition, the acquired knowledge of HKIS should be spread to other firms becoming a positive externality instead of an entry barrier.

Despite the productivity determinants of the service sector has been recently explored, in contrast to the manufacturing sector, individual and contextual determinants are less identified. In this paper the authors use a large set of firm characteristics that might affect productivity in service firms.

La industria de servicios se ha convertido en un sector importante para el crecimiento económico, particularmente en los países en desarrollo. En este contexto, el objetivo de este artículo es comparar los determinantes de la productividad entre empresas que operan en sectores de servicios de baja y alta intensidad de conocimiento (LKIS y HKIS) en Ecuador.

Utilizamos un método de estimación de dos pasos. En primer lugar, estimamos la productividad de las empresas y, en segundo lugar, los determinantes de la productividad. Para esto, utilizamos una base de datos de panel no balanceado sobre los estados financieros de las empresas formales ecuatorianas de los años 2007 a 2018.

Nuestros resultados muestran que las empresas LKIS son ligeramente más intensivas en mano de obra en comparación con las empresas HKIS. Los determinantes de la productividad son similares entre las empresas HKIS y LKIS, excepto por las exportaciones y la concentración del mercado. Las empresas HKIS son más productivas cuando el nivel de competencia es bajo, lo que indica que un mayor poder de mercado está asociado con una mayor productividad. La influencia de los impuestos sobre la productividad depende del tamaño de la empresa. Las pequeñas y medianas empresas se ven más negativamente afectadas que las grandes empresas.

Los impuestos deben diseñarse considerando el tamaño de las empresas, ya que podrían afectar su productividad. Por lo tanto, impuestos más bajos para las pequeñas y medianas empresas pueden reducir la desigualdad entre el tamaño de las empresas. Además, el conocimiento que tienen las HKIS debe extenderse a otras empresas convirtiéndose en una externalidad positiva en lugar de una barrera de entrada.

A pesar de que los determinantes de la productividad del sector servicios se han explorado recientemente, en contraste con el sector manufacturero, los determinantes individuales y contextuales están menos identificados. En este artículo utilizamos un amplio conjunto de características de las empresas que podrían afectar la productividad en las empresas de servicios.

This paper analyzes the age pay gap in Italy (22%), particularly as it is of interest in an aging society and as it may affect social cohesion. Instead of the traditional approach for model selection, we use a machine-learning approach (post double robust Least Absolute Shrinkage Operator [LASSO]). This approach allows us to reduce Omitted Variable Bias (OVB), given data restrictions, and to obtain a robust estimate of the conditional age pay gap. We then decompose the conditional gap and analyze the impact of four further potential sources of heterogeneity (workers', sectors', and occupations' permanent heterogeneity as well as sample selection bias). The results suggest that age discrimination in pay is only perceived but not real in Italy for both men and women.

The aim of this paper is to analyse the effects of overeducation on wages in the Italian graduate labour market.

The relationship between overeducation and wages is analysed using a double selection approach. Two basic individuals' decisions are explicitly considered in the analysis: the decision to work and the choice of occupation. The first one could create a problem of sample selection bias, whereas the second one could generate an endogeneity bias.

Although in line with previous studies it was found that overeducated workers earn less than their appropriately educated peers, the results suggest also that this pay gap is significantly higher when a double selectivity approach is used than when an OLS approach is employed. The main reason why OLS techniques significantly underestimate the wage penalty associated with overeducation appears to be the bias introduced by the endogeneity of overeducation.

Recent studies have examined the impact of overeducation on earnings using a single selection framework. This paper extends previous work by analysing the relationship between overeducation and wages using a double selection approach. Additionally, little research has focused on overeducation in Italy.

Purpose – This essay attempts to answer the question, “What distinguishes inter-human influence from other forms of influence?”

Design/methodology/approach – Specifying the micro-foundations of social structures in terms of communicative inferences necessitates a revision of the concept of social structures (and institutions) as distributed, and hence, uncertain, structures of expectation. Institutional realities are generated in linguistic interaction through the indirect communication of generic references. The generalizing function of language – in particular, abstraction and memory – coupled with its reflexive function, to turn references into things, are sufficient to generate both social structures and institutions as collective inferences.

Findings – Social relations are fundamentally communicative relations. The communicative relation is triadic, implying an enunciator, an audience, and some referential content. Through linguistic communication, humans are capable of communicating locally with others about others nonlocally. Institutions exist only as expectations concerning the expectations of others. These expectations, however, are not only in the mind, and they are not exclusively psychological entities. Linguistically, these expectations appear as the reported statement within the reporting statement, that is, they are constituted through indirect discourse.

Research limitations/implications – An important implication for current sociological theory is that, from the point of view of a sociology defined as communication about communication from within communication, institutional realities should not be reified as existing naturalistically or objectively above or behind the communications through which they are instantiated.

Originality value – This approach, then, is decidedly anti-“realist.” The goal of such research is to examine the inadequacy of nonreflexive models of social order. Accounts of how sets of social relationships emerge will remain inadequate if they do not reflect upon the cognitive and communicative processes which make possible the consideration of such structures.

The purpose of this paper is to present the optimal double sampling attribute plan using the weighted Poisson distribution.

For the given AQL and LQL, sum of producer’s and consumer’s risks have been attained. Based on the weighted Poisson distribution, the sum of these risks has been optimized.

In the final inspection, the producer and the consumer represent the same party. So, the sum these two risks should be minimized. In this paper, the sum of risks has been tabulated using the weighted Poisson distribution for different operating ratios. These tabulated values are comparatively less than the sum of risks derived using Poisson distribution.

The sampling plan presented in this paper is particularly useful for testing the quality of finished products in shop floor situations.

The aim of this paper is to identify the factors that influence rice farmers' decisions to adopt crop insurance and premium payments (willingness to pay [WTP] amounts). The paper also demonstrates the usefulness of the complementary log-log (cloglog) truncated Poisson double-hurdle model as an alternative hurdle model.

The study first investigated the nature of the dependent variable, which had non-normal residuals and was overdispersed. The probit truncated normal regression double-hurdle model was tried but it failed the normality and homoscedasticity tests; hence, the cloglog truncated Poisson double-hurdle model was employed in the study.

An estimated 61% of respondents would purchase crop insurance, despite farmers not having prior experience with this product. Amongst others, the factors that influence insurance adoption amongst rice farmers are the share of rice in total income, reliability perception of crop insurance schemes and the probability of failure to achieve target yields. The latter helps the authors to address adverse selection, a central issue to the viability of such an insurance programme. The determinants of farmers' WTP are also identified.

Sampling was limited to farmers using irrigation and living in one region of Ghana, which may limit the study’s wider applicability.

As far as the authors are aware, this study is the first to select the appropriate hurdle model based on established properties of the dependent variable on this topic – crop insurance decisions.

For a predetermined form of business entry, the international market research process for selecting country markets requires the research questions and research process to be tailored to the entry mode. Retail business franchisors researching potential international markets must not only research market and demand conditions but also explicit issues related to partner selection, the business system's need for adaptation and contract development, often in different cultural and legal contexts. The paper aims to propose a framework that identifies the research issues and a process for implementing a retail business franchise system into international markets.

The need for a tailored approach is established by drawing from the business franchising and international market research literature. Critical issues that may face franchisors and potential partners are ordered into a framework that can be used to guide decision‐making of the parties involved.

The research framework seeks to qualify potential partners, adjustments that may be required to the business system for a specific market and parameters for the contract that will bear on the investment return. The three‐step market research process offers a prescriptive approach that integrates market selection with the entry mode.

The proposed framework encompasses all potential parties. It offers a checklist of potential problems as well as a process for negotiating through to an outcome that strengthens the likelihood of a successful transfer.

The authors consider how the mode of data collection (Internet vs. paper) alters individuals’ responses to different types of survey questions, including subjective, recall, and factual questions. The authors isolate the measurement effect of the mode from the sample selection effect by exploiting predata in a convenience consumer panel. The authors propose using panelists’ reward point balance as exclusion restriction to correct for differing response probabilities by mode, because the reward point balance depends on the timing of the survey invitations and is a source of random variation in response incentive. The authors evaluate average and quantile measurement effects in a mixed-mode Web/paper survey and find statistically significant evidence of mode effects in subjective and recall questions.

The data from the Swiss Labour Force Survey (SAKE) have been widely used to estimate wage functions, which in turn have been applied for the determination of wage discrimination between genders. One serious problem with the SAKE data is that about 17 per cent of employed individuals did not report wages. Those studies which use the SAKE data to estimate wage functions simply ignore these non‐respondents. Such an approach could lead to a serious selectivity bias if the response decision is not purely random. In this study this issue is analysed in a double‐selectivity framework, in which both this response decision and the usual market‐participation decision are modelled. Although the response decision can be partially explained by certain socio‐economic variables, a large degree of randomness/unexplained variation exists. The authors therefore conclude that, in the absence of a better model, the standard approach at estimating wage functions (i.e. only correcting for the selectivity bias arising from women’s participation decision) is the most appropriate one.
