Could lean practices and process innovation enhance supply chain sustainability of small and medium‐sized enterprises?

Small and medium‐sized enterprises (SMEs) adopt lean practices (LP) to reduce waste across their organisational value chain, which helps achieve sustainability. Process innovation (PI) has also been applied through cleaner production, environmental management system, ecodesign, and so on to address both customers' needs and legislations by policymakers. Although prior studies reveal the effect of sustainable practices, LP, and PI on sustainable performance separately, less is known on the integrated effect of them on sustainability performance. Moreover, studies on mediating effect of LP and PI on sustainability performance are scant. This is significant as LP and PI are considered to be the enablers for achieving sustainability performance. This research addresses this knowledge gap. The research first theorises a model integrating these four major constructs (sustainability practices, LP, PI, and sustainability performance) through hypotheses development. Subsequently, using structural equation modelling, it is tested whether each of sustainability practices, LP, and PI effect sustainability performances. Additionally, mediating effect of LP and PI between sustainability practices and performances is derived. The study uses data from 119 SMEs within manufacturing industries in the Midlands, United Kingdom. Further, a few case studies have been undertaken to validate the findings from quantitative analysis. The overall results show that although sustainability practices, LP, and PI help achieve sustainability performance of SMEs supply chain through efficiency and responsiveness respectively, the mediating effect LP is more compared with PI. Moreover, SMEs adopt LP when they are economy focused and implement PI when they are pressurised by customers and/or policymakers.     

Identifying bank outputs and inputs with a directional technology distance function

The bank efficiency literature lacks an agreed definition of bank outputs and inputs. This is problematic given the long-standing controversy concerning the status of deposits, but also because bank efficiency estimates are known to be affected by the inclusion of additional outputs such as non-traditional (fee-based) activities or risk measures. This paper proposes a data-driven identification of bank outputs and inputs using the directional technology distance function. While previous applications of this tool used symmetric expansion or contraction directions, we focus on a set of orthogonal directions, each corresponding to an assumption on the input/output status of an individual variable. These directions correspond to a set of different specifications, whose estimated coefficients can be used to determine the input or output status of all variables except the regressand. Our empirical analysis revealed a very consistent pattern across the alternative specifications estimated. There is strong evidence that customer deposits are an input, and that non-performing loans are an important undesirable output. Finally, the orthogonal expansions/contractions we consider avoid the simultaneity problem raised by the “convenient normalization” commonly used to impose linear homogeneity in stochastic frontier estimation.     

Exchange Rates and Stock Prices in the MENA Countries: What Role for Oil?

This paper considers the linkage between stock prices and exchange rates in four MENA (Middle East and North Africa) emerging markets. In contrast to the existing evidence that uses a global market index to uncover such a relationship it is found that for the sample countries oil prices emerge as the dominant factor in the above relationship. The paper considers the presence of regime shifts and evidence is found of cointegration only for the period following the 1999 oil price shock. Readjustment towards equilibrium in each stock market occurs via oil price changes. Finally, a number of robustness checks are performed and persistence profiles produced.     

Corporate dividend policy in practice: Evidence from an emerging market with a tax-free environment

Several theories have been proposed to explain why companies pay dividends. However, as of today, the dividend policy remains a puzzle as no convincing explanation has been given as to why firms pay cash dividends to their shareholders. This paper contributes to this debate by examining the dividend policy in an emerging market that has a tax-free environment. Specifically, we follow Brav et al. (2005) and examine this issue using survey and field interviews, in the particular context of the United Arab Emirates. Our results provide support for the proposition that dividend policy is conservative. We also find that dividends in the UAE are considered by managers as a residual cash flow, and are determined after investment decisions are made. When examining the determinants of dividend policy, we find that taxes are not important, that institutional investors are expected to play a role in disciplining managers, and that dividends may play a disciplinary role as well in controlling agency conflicts.     

Measuring Nonprofit Incubator Performance: Toward an Adapted Balanced Scorecard Approach

The number of business incubators in the world has risen dramatically, with many regions promoting nonprofit incubators. Yet declines in public funding have brought to the fore a key question about how well they perform. Both policymakers and incubator managers therefore stand to benefit from reliable tools to monitor performance. In this paper, we present a scale to measure incubator performance based on the research literature on incubator performance and management control. We used the balanced scorecard as a basis for thought about how best to develop a model of nonprofit incubator performance. Data collected from 121 incubator managers show that performance can be assessed along four constructs: local development performance, incubatee satisfaction, incubation processes, and learning. This tool comprises a broad range of performance indicators and, perhaps more importantly, may help incubator managers to better run their organizations and regional policymakers to better evaluate their entrepreneurship policies.     

Technology transactions,announcement effect,and reversal: Dissecting an anomaly

We examine the short term stock price performance of firms that acquire or sell technology rights. We find significant positive announcement-period abnormal returns to the acquirers and sellers. However, the price increases reverse during the subsequent twenty trading days. These quick fortune reversals cannot be attributed to methodology; they prevail in the late 1970s through the 2000s, in bear and bull stock markets, and in both high and low technology industries. Upon splitting the sample into two subsamples comprised each of stocks with either pre-announcement price run-up or decline; we find that the abnormal return reversal is confined to the latter subsample. Stocks that witness price run-up prior to the announcement do not reverse to original prices but lose the momentum right after the announcement-period. We believe this is caused by the combination effect of the momentum prior to-and the impact of the announcement.     

Threshold effects in the patent-growth relationship: a PSTR approach for 60 developed and developing countries

ABSTRACT

This study analyzes whether there is a threshold effect in the innovation-growth relationship. Using data from the period 2008–2017, we perform an analysis using 60 countries in the whole sample and a split-sample analysis in which we separate developed countries (36) from developing countries (24). The results for the panel smooth transition regression (PSTR) model indicate that there is a threshold effect in the innovation-growth relationship. We find that below the threshold, the effect of innovation measured by the number of patents is not significant for developed and developing countries. However, surpassing the optimal threshold, the effect becomes positive only for the whole sample and developed countries. Furthermore, findings also indicate that research and development expenditure, domestic and foreign investments stimulate economic growth.
