This paper investigates the economic growth response to public infrastructure expenditure shocks in Nigeria. Quarterly time-series data spanning 1981:Q1 to 2019:Q4, sourced from the Central Bank of Nigeria Statistical Bulletin are used in the study. The structural vector auto-regressive method following Blanchard and Perrotti’s (2002) with Augmented Dickey-Fuller, Phillips and Perron, and Kwiatkowski-Phillips-Schmidt-Shin stationarity tests are employed in the paper. The results of the stationarity tests showed that all the model’s variables namely; real gross domestic product, public infrastructure expenditure, and government revenue became stationary after their first difference. However, the study extracted and classified the variance decomposition and impulse response functions into three regimes namely; short, medium, and long-term respectively. The findings reveal that in the short term, 10.5% variations in economic growth were associated with public infrastructure expenditure shocks while in the medium term, 29.7% variations in economic growth were associated with public infrastructure expenditure shocks, and in the long term, 42.6% variations in economic growth were associated with public infrastructure expenditure shocks in Nigeria. Economic growth responses to public infrastructure expenditure shocks were positive and statistically significant in the three regimes of short, medium, and long-term respectively. The study recommends that the federal government should concentrate more on reforms and spending policies that will result in the best possible policy and ultimately high and sustainable growth in Nigeria.
本文研究了尼日利亚经济增长对公共基础设施支出冲击的响应。本研究使用了1981年第一季度至2019年第四季度的季度时间序列数据,这些数据来自尼日利亚中央银行统计公报。本文采用了继Blanchard和Perrotti(2002)之后的结构向量自回归方法与增广Dickey-Fuller, Phillips和Perron,以及Kwiatkowski-Phillips-Schmidt-Shin平稳性检验。平稳性检验结果表明,模型的所有变量分别为;实际国内生产总值(gdp)、公共基础设施支出和政府收入在出现第一次差异后趋于稳定。然而,该研究提取并将方差分解和脉冲响应函数分为三种类型:分别是短期、中期和长期。研究结果显示,在短期内,10.5%的经济增长变化与公共基础设施支出冲击有关,而在中期,29.7%的经济增长变化与公共基础设施支出冲击有关,从长期来看,尼日利亚42.6%的经济增长变化与公共基础设施支出冲击有关。经济增长对公共基础设施支出冲击的响应在短期、中期和长期三种机制下分别是积极的和统计显著的。该研究建议,联邦政府应该更多地关注改革和支出政策,这将导致尼日利亚的最佳政策和最终的高和可持续增长。

Entrepreneurship is becoming increasingly popular in educational institutions worldwide. The aim is to familiarize students with the topic and potentially strengthen their desire to become entrepreneurs. Research has shown that a person’s behavior is influenced by their intention, which makes it essential for researchers to examine the factors that contribute to the development of intention. This research is focusing on how certain demographic factors can affect the desire of Nepali business students to become entrepreneurs. The study involved 343 MBA students from 13 business schools in Kathmandu City who were given a self-administered questionnaire. The data collected was analyzed using Independent Sample T-test and One-way ANOVA. The demographic factors that were considered in the study include gender, age, marital status, working experience, and prior exposure to entrepreneurship courses. The findings suggest that male students have a slightly greater inclination toward entrepreneurship. Age, marital status, and prior work experience show practically no impact. We also found no relationship between entrepreneurial intention and prior exposure to entrepreneurship courses. The findings clearly contradict the currently available literature demonstrating the significance of all these influencing factors. The study provides possibilities for future studies and practical applications for policymakers and professionals in the field.
创业在世界各地的教育机构中越来越受欢迎。其目的是让学生熟悉这个话题,并有可能增强他们成为企业家的愿望。研究表明,一个人的行为受到他们的意图的影响,这使得研究人员有必要研究促进意图发展的因素。这项研究的重点是某些人口因素如何影响尼泊尔商科学生成为企业家的愿望。这项研究涉及来自加德满都市13所商学院的343名MBA学生,他们被要求填写一份自我填写的问卷。收集的数据采用独立样本t检验和单因素方差分析。研究中考虑的人口因素包括性别、年龄、婚姻状况、工作经验和之前参加过创业课程。研究结果表明,男生的创业倾向略高。年龄、婚姻状况和以前的工作经验几乎没有影响。我们还发现,创业意向与之前接触过的创业课程之间没有关系。这一发现明显与现有文献所显示的所有这些影响因素的重要性相矛盾。该研究为该领域的政策制定者和专业人士提供了未来研究和实际应用的可能性。

This study thesis analyses the Starbucks business model in Prague and Richmond from the location perspective, focusing on the company’s consumers and their decision-making towards commuting to the stores. Using modified Salop’s circle model, the transportation costs of the average Starbucks consumer in both cities are calculated, explained, and compared. It is revealed that the average Starbucks consumer in Richmond bears, on average, 1.255x higher transportation costs than the one in Prague and is willing to travel 2.54x higher distances to purchase the average Starbucks product. In addition, after analyzing transportation costs, the study offers a real-life applicable business proposal for where to place a new Starbucks store in both cities, based on several techniques often used in business consulting for solving case studies. The suggested most suitable location for the new store in Prague is the Prague main railway station. In contrast, the best location in Richmond is the intersection of West Broad Street E and North Lombardy Street, close to Virginia Commonwealth University. The study’s main contribution is the inverting of Salop’s circle model and emphasizing transportation costs as an endogenous variable. In general terms, this study may guide spatial optimization in business strategies, from circular economy applications to strategic managerial decisions in locations with different consumer sensitivity to transportation costs.
本文从地理位置的角度分析了星巴克在布拉格和里士满的商业模式,重点关注公司的消费者及其通勤决策。使用修正的Salop圈模型,计算、解释和比较了两个城市星巴克普通消费者的交通成本。据透露,里士满的星巴克消费者平均承担的交通成本是布拉格消费者的1.255倍,并且愿意走2.54倍的路程购买星巴克的普通产品。此外,在分析了交通成本后,该研究基于商业咨询中常用的解决案例研究的几种技术,为在这两个城市新建星巴克门店提供了一个现实可行的商业建议。建议在布拉格开设新店最合适的地点是布拉格火车总站。相比之下,里士满最好的位置是西布罗德街E和北伦巴第街的交叉口,靠近弗吉尼亚联邦大学。该研究的主要贡献是推翻了Salop的圆模型,并强调运输成本是一个内生变量。总的来说,这项研究可以指导商业战略的空间优化,从循环经济应用到消费者对运输成本敏感度不同的地区的战略管理决策。

This study examined the impact of fiscal federalism on economic development in Nigeria over the period 1981 to 2020 using annual time series. Both revenue and expenditure decentralization were used as measures of fiscal federalism. Analytically, the study employed the autoregressive distributed lag approach. The result reveals that in the long run, revenue and expenditure decentralization have a positive and significant impact on economic development in Nigeria, and many scholars have validated this finding. This finding shows that true fiscal federalism is better captured by both subnational revenue and expenditure decentralization. Given the finding, the study suggests that more fiscal power should be devolved to state and local governments in Nigeria through appropriate legislation.
本研究利用年度时间序列考察了1981年至2020年期间尼日利亚财政联邦制对经济发展的影响。收入和支出分权都被用作财政联邦制的衡量标准。分析上,本研究采用自回归分布滞后方法。结果表明,从长期来看,收入和支出分权对尼日利亚的经济发展具有积极而显著的影响,许多学者已经验证了这一发现。这一发现表明,地方财政收入和支出的分权更能体现真正的财政联邦制。鉴于这一发现,该研究建议,应该通过适当的立法将更多的财政权力下放给尼日利亚的州和地方政府。

The aim of the study is to find patterns in an exact complete data set containing the annual budget of all municipal subjects in the Czech Republic over the past 20 years. The focus of the analysis is on which resources could enable the development of and investment in municipal assets, especially estate property. The financial and real estate analysis (FAMA) method was chosen, which provides comparable indicators to calculate the debt service and other related features of subject performance on a municipal level. These indicators demonstrate whether municipal subjects follow responsible budgeting principles and/or how they utilize their own resources. Comparing similar studies using mentioned data and methodology there is a gap between context of data in time a relation chosen indicators. The reason of obstacle is to put data in time-series and properly analyze them. This appropriate items of indicators are aggregated so all the connections between them and other items are lost. In enormous amount of data study uses classification tools to unfold hidden patterns how does municipal budgeting develop in time without knowing details about each case in context of debt and assets. Study convert time dimension to static indicator of its dynamics a using pure K-Means classification conclude having 6 different clusters which differ each other in some of indicators. Within broader context of those clusters we propose an overview of municipal budgeting strategies. In big cities dominates financing of investment by debt and the rest of clusters differs usually significantly with small impact of their population size that is one of determinants budget income therefore essential budget part.
这项研究的目的是在一个准确完整的数据集中找到模式,该数据集包含捷克共和国过去20年所有市政科目的年度预算。分析的重点是哪些资源可以促进市政资产的开发和投资,尤其是房地产。选择了金融和房地产分析(FAMA)方法,该方法提供了可比指标,用于计算市一级的偿债情况和主体绩效的其他相关特征。这些指标表明市政主体是否遵循负责任的预算编制原则和/或如何利用自己的资源。比较使用上述数据和方法的类似研究,数据上下文与时间关系选择的指标之间存在差距。障碍的原因是将数据放在时间序列中并对其进行适当的分析。这些适当的指标项目被聚合,因此它们与其他项目之间的所有连接都会丢失。在大量的数据中,研究使用分类工具来揭示隐藏的模式,即在不了解债务和资产背景下每个案例的细节的情况下,市政预算是如何及时发展的。研究将时间维度转换为其动态的静态指标,使用纯K-Means分类得出结论,有6个不同的聚类,在某些指标上彼此不同。在这些集群的更广泛背景下,我们建议对市政预算战略进行概述。在大城市,债务投资融资占主导地位,而其他集群通常差异很大,其人口规模的影响很小,这是预算收入的决定因素之一,因此是必不可少的预算部分。

Within a broad discussion on property price formation and property market specifics this paper aims to investigate the relationship between property price trends and number of transactions occurred on housing market. Specifically, we test if housing transaction volumes and rents are good predictors of housing prices and discuss causalities and differences in this relationship on the sales and rental property markets. We bring evidence from selected European property markets about the relationship between property price trend and number of transactions occurring on this market. We argue that increased number of transactions is predictive of increase in property price, but prices tend to be rigid in the opposite (downward) direction. Thus, cooling down of demand for properties may rather decrease number of transactions than push down property prices. This appealing result may bring light into understanding why property prices appreciate across time and countries.
在对房地产价格形成和房地产市场具体情况的广泛讨论中,本文旨在调查房地产价格趋势与住房市场交易数量之间的关系。具体来说,我们测试了住房交易量和租金是否是房价的良好预测因素,并讨论了这种关系在房地产销售和租赁市场上的因果关系和差异。我们从选定的欧洲房地产市场获得了房地产价格趋势与该市场交易数量之间关系的证据。我们认为,交易数量的增加预示着房地产价格的上涨,但价格往往是刚性的(向下)方向。因此,房地产需求的降温可能会减少交易数量,而不是压低房地产价格。这一吸引人的结果可能会让我们理解为什么房地产价格会随着时间和国家的推移而上涨。

This paper analyses an employment support programme – the Antivirus A Programme – implemented in the Czech Republic during the COVID-19 pandemic aimed at maintaining a constant level of employment. We present this government programme in detail, including individual data related to its effectiveness and examine similar employment support programmes in other EU countries during the pandemic. We also analyse the economic development of sectors that received employment support. The main contribution of the paper is the creation of a counterfactual scenario of unemployment and inflation rate in the Czech Republic in the absence of the Antivirus A Programme using a short-run Phillips curve concept. According to Bajgar et al. (2021), one third of Czech workers could work from home during the pandemic. We find that if these workers had not been supported by the Antivirus A Programme, Czech taxpayers could have saved EUR 0.15 billion and inflation rate could have been reduced (based on our short-run Phillips curve model) by 0.66–0.99 p.p. for the entire duration of the Antivirus A Programme depending on the choice of assumptions related to the possibility of working from home.
本文分析了在新冠肺炎大流行期间在捷克共和国实施的一项就业支持计划——抗病毒A计划,旨在保持恒定的就业水平。我们详细介绍了这项政府计划,包括与其有效性相关的个人数据,并研究了疫情期间其他欧盟国家的类似就业支持计划。我们还分析了获得就业支持的部门的经济发展情况。该论文的主要贡献是使用短期菲利普斯曲线概念,在没有抗病毒a计划的情况下,创建了捷克共和国失业率和通货膨胀率的反事实情景。根据Bajgar等人(2021)的数据,在疫情期间,三分之一的捷克工人可以在家工作。我们发现,如果这些工人没有得到抗病毒A计划的支持,捷克纳税人本可以节省1亿欧元,并且在抗病毒A计划期间,通货膨胀率(根据我们的短期菲利普斯曲线模型)可能会降低0.66–0.99 p.p.,这取决于与在家工作的可能性相关的假设的选择。

A Tool for Evaluating Public Procurement in the Context of Life Cycle Costs 从生命周期成本角度评估公共采购的工具
IF 2.4 Q1 ECONOMICS Pub Date : 2023-05-01 DOI: 10.52950/es.2023.12.1.006
D. Macek
The paper deals with the issue of selection procedures. The goal is to show how it is possible to incorporate a view of life cycle costs into the tender process, and not only deal with the aspect of investment costs. The paper is proposed by the Life Cycle Cost Inspector (LCCI). LCCI divides investment opportunities into individual components with their own operating characteristics and costs, allowing for a clear comparison of different investment alternatives. The tool considers acquisition costs, operating costs, and disposal costs over a specific period. LCCI also allows for reverse evaluation, where investment costs are modified based on efficiency. The tool's universality enables its use across various sectors, not just the construction industry. The author aims to shift public practice from tendering "on price" to "tendering on quality" by providing a simple methodology for comparing investment options based on the entire life cycle costs. The application is based on the Building Cost Information Service (BCIS) standard issued by the Royal Institution of Chartered Surveyors (RICS).
该文件涉及甄选程序问题。目标是展示如何将生命周期成本的观点纳入招标过程,而不仅仅是处理投资成本方面。本文由生命周期成本检查员(LCCI)提出。LCCI将投资机会划分为具有各自运营特征和成本的各个组成部分,以便对不同的投资选择进行明确的比较。该工具考虑了特定时期内的收购成本、运营成本和处置成本。LCCI还允许反向评估,即根据效率修改投资成本。该工具的通用性使其能够在各个部门使用,而不仅仅是在建筑行业。作者旨在通过提供一种基于整个生命周期成本比较投资选择的简单方法,将公共实践从“基于价格”的投标转变为“基于质量的投标”。该申请基于英国皇家特许测量师学会(RICS)发布的建筑成本信息服务(BCIS)标准。

The goal is to show how it is possible to incorporate a view of life cycle costs into the tender process, and not only deal with the aspect of investment costs. The paper is proposed by the Life Cycle Cost Inspector (LCCI). LCCI divides investment opportunities into individual components with their own operating characteristics and costs, allowing for a clear comparison of different investment alternatives. The tool considers acquisition costs, operating costs, and disposal costs over a specific period. LCCI also allows for reverse evaluation, where investment costs are modified based on efficiency. The tool's universality enables its use across various sectors, not just the construction industry.

This paper aims to analyse the crypto market in India from the viewpoint of consumers who could potentially trade in these markets and extend the extent of their behaviour to the importance of a regulatory body within the economy. The central idea of this paper is to estimate the importance of a central bank in the minds of people and how it affects their trust on a currency which is unregulated. This forms the first tier of the paperIn order to get insight into the more technical dynamics of cryptocurrencies, the paper then studies cryptocurrency from the point of view of experts who explain the different dimensions of the crypto markets. This forms the second tier of the paper.The paper aims to analyse from the surveys conducted and the available literature, the nature of the crypto market in India with a more reporting approach than a problem-solving model.The research is based on primary data collected by means of surveys and structured interviews. These are termed as the two tiers in the paper. Using quantitative statistical analysis to find the common trend of the sample and a descriptive approach for the analysis of the interviews, the paper examines how the two tiers behave single-handedly and their dynamic when they interact.
本文旨在从可能在这些市场进行交易的消费者的角度分析印度的加密货币市场,并将他们的行为范围扩展到经济中监管机构的重要性。本文的核心思想是评估央行在人们心目中的重要性,以及它如何影响他们对不受监管货币的信任。这构成了论文的第一层。为了深入了解加密货币的更多技术动态,论文从解释加密货币市场不同维度的专家的角度研究加密货币。这构成了论文的第二层。本文旨在通过调查和现有文献分析印度加密货币市场的性质,采用更多的报告方法,而不是解决问题的模型。这项研究基于通过调查和结构化访谈收集的初步数据。这在论文中被称为两个层次。使用定量统计分析来发现样本的共同趋势,并使用描述性方法来分析访谈,本文考察了两个层次在互动时的单独行为及其动态。

This research aims to estimate the determinants of firm performance during the COVID-19 pandemic. For this purpose, the sample of Slovenian non-financial listed firms operating in the period 2017 – 2021 is used. Firm performance is expressed with market-based as well as accounting-based performance measures, including Tobin's Q, ROA, and ROE, while potential determinants encompass several firm-oriented variables. These are the firm size, liquidity expressed with the current ratio, leverage, tangibility, sales growth, age of the firm as well as COVID-19 dummy variable. The results of dynamic panel analysis disclose that liquidity, leverage, sales growth, and COVID-19 dummy are statistically significant in explaining firm performance. Specifically, liquidity and leverage are found to be significant in explaining Tobin's q, sales growth is a statistically significant determinant of both ROA and ROE while the latter is also negatively impacted by leverage and the COVID-19 dummy.
本研究旨在估计新冠肺炎大流行期间企业绩效的决定因素。为此,使用了2017-2021年期间运营的斯洛文尼亚非金融上市公司的样本。企业绩效用基于市场和会计的绩效指标来表示,包括托宾Q、ROA和ROE,而潜在的决定因素包括几个面向企业的变量。这些是公司规模、以流动比率表示的流动性、杠杆、有形资产、销售增长、公司年龄以及新冠肺炎虚拟变量。动态面板分析的结果显示,流动性、杠杆率、销售增长和新冠肺炎模型在解释公司业绩方面具有统计学意义。具体而言,流动性和杠杆率被发现在解释Tobin的q时具有重要意义,销售增长是ROA和ROE的统计显著决定因素,而ROE也受到杠杆率和新冠肺炎模型的负面影响。
