Domestic Food

PurposeEmpirical studies have documented the linkage between exchange rate movement and food prices. However, the purpose of this study is to investigate the degree and direction of returns and volatility spillover transmission between exchange rate and domestic food prices in Nigeria.Design/methodology/approachThe study uses weekly data from January 2010 to January 2019. Also, the study adopts the improved Diebold and Yilmaz (2012) approach to evaluate the return and volatility spillover between food price and naira to dollar exchange rate. The study also account for 2016 exchange rate crash in the interconnectedness between food prices and naira to dollar exchange rate.FindingsThe paper finds evidence of directional interdependence among the considered food prices and exchange rate based on the obtained spillover indexes. In addition, exchange rate returns and volatility transmission to food prices is more than it receives, particularly after the exchange rate crash.Research limitations/implicationsThe high consumption of staple foods requires policies on price stabilisation such as massive investment in local production and reduction in import dependence, in order to cushion the effects of exchange rate depreciation on domestic prices of food.Originality/valueThis study is the first empirical study to investigate the interconnectedness between exchange rate and domestic food prices for a food import–dependent developing country using the Diebold and Yilmaz approach.

Significance From late October to late November 2019, beef prices in Brazil increased, on average, by 35%, with the price of fattened cattle reaching over 230 reais (approximately 55 dollars) per 15 kilograms at the peak. Much of the sharp increase was due to rising Chinese demand for Brazilian beef after an African swine fever epidemic reduced Chinese pork production by over 30%. Exchange rate depreciation, domestic consumption and supply constraints have also contributed to lift domestic prices. Impacts Chinese efforts to reduce prices may hit beef exporters who have invested in infrastructure to meet Chinese demand. There is no risk of a beef shortage in Brazil, but prices are likely to remain high at least temporarily. Consumer shifts to alternative meats could also boost a range of food prices, hitting purchasing power.

The Impact

Purpose – This paper aims to examine the relationship between Indian rupee-US dollar exchange rate and the macroeconomic fundamentals for the post-economic reform period. Design/methodology/approach – The authors have used an empirical model which includes a range of important macroeconomic variables based on the basic monetary theories of exchange rate determination. At the first stage of the analysis, they have tested structural break in the data. Subsequently, they have employed the fully modified ordinary least square, Wald’s coefficient restriction and impulse response functions (IRF) to estimate the monetary model in the long- and short-run horizons. Findings – Results of analyses indicate that the macroeconomic fundamentals determine exchange rate in a significant way, but their effect varies sizably across the periods. The IRF illustrate the importance of interest rate in controlling exchange rate volatility. Practical implications – The analysis of the behavior of inter-relationship among macroeconomic variables will help policymakers in a deep-rooted understanding of this complex and time-varying relationship. Originality/value – Most of the existing studies have tested the impact of a single or a few macroeconomic fundamentals on exchange rate. But in the present study, we have tested the impact of a range of important variables, i.e. money supply, real income or output, price level and trade balance. Further, considering the importance of structural breaks in data, they authors have employed standard tests of structural break and incorporated the issue in the cointegration analysis.

Purpose The purpose of this study is to examine and understand the experiences of tourists in the Turkish coffee houses in Istanbul, Turkey. Design/methodology/approach In this study, a qualitative case study method was used to analyze tourists’ comments with user-generated content technique by analyzing tourists’ comments. The data used in the study was collected through TripAdvisor, which is considered one of the most famous websites with tourist reviews and comments, between 20 May and 10 June 2020 from tourists’ reviews (n:219). Findings The findings show that Turkish coffee house experiences are heterogeneous based on the dimensions of coffee characteristics, place, satisfaction, recommendation and revisit intention, value/price and value-added experience. Moreover, value-added experience includes some sub-themes such as a memorable experience, authentic experience and culture learning experience. Originality/value There are some studies on Turkish coffee and Turkish coffee culture in the literature, but there have been no empirical studies investigating the Turkish coffee house experiences of tourists. For this reason, this study aims to examine and understand the experiences of tourists in Turkish coffee houses. Therefore, it is believed that this study will fill the current gap in the literature on tourists’ experiences of Turkish coffee houses.

Purpose This paper aims to investigate the roles of corruption and tax allocation inefficiency in moderating the effect of tax aggressiveness on sustainable welfare. Design/methodology/approach This research uses a fixed-effect multiple regression analysis for 55,438 firm-year observations covering 22 countries from 2007 to 2017. Findings For less (more) tax-aggressive observations, corruption and tax allocation inefficiency strengthen the negative (positive) effect of tax aggressiveness on sustainable welfare. The results are in line with public choice and functionalism theories that suggest that private investments can increase welfare when governments are dysfunctional. Practical implications This paper shows that the effect of tax aggressiveness on sustainable welfare depends on tax aggressiveness, corruption and tax allocation inefficiency. Social implications This paper implies that governments should reduce their corruption levels and increase tax allocation efficiency because private investments are ineffective in the long run. Originality/value Because of increasing awareness of sustainability issue, sustainable welfare is considered more relevant than traditional welfare. Hence, empirical studies on the effect of tax aggressiveness on sustainable welfare are crucial. This paper adds the literature by combining public choice and functionalism theories to investigate the moderating roles of corruption and tax allocation inefficiency in this issue.

Significance Last year brought yet another large grain harvest and other farming sectors including meat and dairy performed well. However, a second year of export restrictions on wheat reflects political worries about managing domestic prices, not actual food availability. Impacts As expected, Russia has renewed its food embargo against Western nations to the end of 2021. A Russian ban on certain produce from Uzbekistan, later reversed, may reflect political friction more than safety concerns. To offset the loss of Uzbek tomatoes, Russia has increased its import quota for Turkey by 25%.

PurposeAs information systems (IS) phenomena continue to emerge and evolve in our ever-changing economic and social contexts, researchers need to increase their focus on time in order to enrich our theories. The purpose of this paper is to present broad suggestions for IS researchers about how they can direct some of their research efforts to consider, conceptualize and incorporate time into research endeavors and how they might be mindful about considering and specifying time-related scope conditions of their research efforts.Design/methodology/approachThe authors synthesize empirical studies and discuss three distinct yet related frameworks of time and the benefits they can provide. The authors choose two research streams that reflect dynamic economic and social contexts – namely, enterprise systems and social networks – to illustrate how time and frameworks of time can be leveraged in our theory development and research design.FindingsThe authors demonstrate that limited research in IS has incorporated a rich conceptualization and/or discussion of time. The authors build on this gap to highlight guidelines that researchers can adopt to enrich their view of time.Originality/valueGiven the dynamic nature of IS phenomena and the increased availability of longitudinal data, the authors’ suggestions aim to urge and guide IS researchers about ways in which they can incorporate time into their theory and study designs.

The Cost

Purpose Empirical studies have found that cost-based pricing remains dominant in pricing practice and suggest that practice conflicts with marketing theory, which recommends value-based prices. However, empirical studies have yet to examine whether cost-plus formulas represent the pricing approach or essence. Design/methodology/approach This study aims to address the factors that explain price setting whereby the cost-plus formula is not just the pricing approach but also the pricing essence. This examination is grounded in a survey conducted on 380 Brazilian industrial companies. Findings The results show that, for price-makers, the cost-based pricing essence is positively associated with four factors (two obstacles to deploying value-based pricing, company size and differentiation), but it is negatively related to one factor (premium pricing strategy). For price-takers, the cost-based pricing essence is positively associated with four factors (two obstacles to deploying value-based pricing, coercive isomorphism and use of full costs), but it is negatively related to five factors (one obstacle to deploying value-based pricing, company size, competitors’ ability to copy, normative isomorphism and experience). Originality/value The key contribution of this paper is demonstrating that cost-plus formulas do not go against the incorporation of competitors and value information. This study reveals that it is possible to set prices based on either value or competitors’ prices while simultaneously preserving the simplicity of the cost-plus formulas. Via the margin, firms may connect costs to information about competition and value. The authors also demonstrate the drawbacks of not segregating companies into price-makers and price-takers and an excessive focus on the pricing approach at the expense of pricing essence.

PurposeThis paper examines the return and volatility spillovers among major cryptocurrency using daily data from 10/08/2015 to 15/04/2018.Design/methodology/approachThe authors employ the Dielbold and Yilmaz (2012) spillover approach and rolling sample analysis to capture the inherent secular and cyclical movements in the cryptocurrency market.FindingsThe authors show that there is substantial difference between the behaviour of the cryptocurrency portfolios return and volatility spillover indices over time. The authors find evidence of interdependence among cryptocurrency portfolios given the spillover indices. While the return spillover index reveals increased integration among the currency portfolios, the volatility spillover index experiences significant bursts during major market crises. Interestingly, return and volatility spillovers exhibit both trends and bursts respectively.Originality/valueThis study makes a methodological contribution by adopting Dielbold and Yilmaz (2012) approach to quantify the returns and volatility transmissions among cryptocurrencies. To the best of our knowledge, little or no study has adopted the Dielbold and Yilmaz (2012) methodology to investigate this dynamic relationship in the cryptocurrencies market. The Dielbold and Yilmaz (2012) approach provides a simple and intuitive measure of interdependence of asset returns and volatilities by exploiting the generalized vector autoregressive framework, which produces variance decompositions that are unaffected by ordering.

Valley Of Death

Purpose The knowledge generated by academics in the field of management is often criticized because of its reduced relevance for professionals. In the review of the literature, the authors distinguish between three streams of thought. The review of the literature and the understanding of the research streams that have been addressed by the academic–practitioner gap in management has allowed to clarify that what truly underlies each of these approaches is a different assumption or paradigm from which the management science focusses. Design/methodology/approach This paper reviews the main approaches that have analysed this topic, drawing a number of conclusions. Findings The knowledge generated by academics in the field of management is often criticized because of its reduced relevance for professionals. In the review of the literature, the authors distinguish between three main perspectives. The review of the literature and the understanding of the research streams that have been addressed by the academic–practitioner gap in management has allowed us to clarify that what truly underlies each of these approaches is a different assumption or paradigm from which the management science focusses. To represent the findings of the literature review in this sense, the authors will present, first, a model that serves as a framework to interpret the different solutions proposed in the literature to close the gap from a positivist paradigm. Subsequently, they question this view through a reflection that brings us closer to a more pragmatic and interpretive paradigm of management science to bridge the research–practice gap. Originality/value In recent studies, researchers agree that there is an important gap between management research and practice, which may bear little resemblance to each other. However, the literature on this topic does not seem to be guided by a rigorously structured discourse and, for the most part, is not based on empirical studies. Moreover, a sizeable body of literature has been developed with the objective of analysing and contributing solutions that reconcile management researchers and professionals. To offer a more systematic view of the literature on this topic, the paper classifies previous approaches into three different perspectives based on the ideas on which they are supported. Finally, the paper concludes with some reflections that could help to reorient the paradigm from which the management research is carried out.
