Adjustment of Input–Output Tables from Two Initial Matrices

The compilation of the information required to construct survey-based input–output (I–O) tables consumes resources and time to statistical agencies. Consequently, a number of non-survey techniques have been developed in the last decades to estimate I–O tables. These techniques usually depart from observable information on the row and column margins, and then the cells of the matrix are adjusted using as a priori information a matrix from a past period (updating) or an I–O table from the same time period (regionalization). This paper proposes the use of a composite cross-entropy approach that allows for introducing both types of a priori information. The suggested methodology is suitable to be applied only to matrices with semi-positive interior cells and margins. Numerical simulations and an empirical application are carried out, where an I–O table for the Euro Area is estimated with this method and the result is compared with the traditional projection techniques.     

Environmental Accounting of Eco-innovations through Environmental Input–Output Analysis: The Case of Hydrogen and Fuel Cells Buses

The introduction of environmentally friendly innovations in both transport and energy sectors are included in the list of priorities of the European Union political agenda. This paper investigates the environmental consequences of the introduction of hydrogen and fuel cells technology in the European economic system by applying environmental input–output analysis and life cycle assessment tools. Hydrogen is produced through the reforming of natural gas and it is employed in fuel cells buses that offer transport services to final consumers. We have built three scenarios based on different assumptions on the final demand. We have shown the results for three impact categories: global warming, photochemical oxidation and acidification. The results suggest that the use of hydrogen in fuel cells buses is only environmentally desirable if accompanied either by the employment of renewable sources or by carbon dioxide capture, or both.     

Qualitative Input–Output Analysis of the Indian Economic Structure

Qualitative input–output (IO) analysis can be considered mostly in terms of a graph-theoretic formulation, which involves the construction and use of an adjacency matrix, derived from a binary transformation of the IO coefficient matrix. Classical attempts at qualitative IO analysis have derived the structure from the direct IO coefficient table. In more recent attempts, greater sophistication has been achieved by incorporating a degree of quantification into the qualitative analysis. Also, the concept of important coefficients (IC) has been used for the construction of the adjacency matrix. The present study is carried out along these lines for the Indian economy.     

Some Relationships between T-Accounts,Input–Output Tables and Social Accounting Matrices

Some relationships between the T-accounting format for presenting commodity balances; input–output (IO) tables; and social accounting matrices are discussed in this paper. The starting point is to recognize that IO tables do not contain all the information that is needed to complete a social accounting matrix (SAM), or, therefore, for the modelling of phenomena that depend on having a fully articulated SAM, such as the interdependence of the distribution of income and the structure of production. There is a need, therefore, to establish the character of the extra information that is required and this can be achieved by imposing the requirement that a SAM should be consistent with the basic cash identity that is fundamental to all social accounting. A second agendum is to develop the argument that, while T-accounts can, in principle, provide a database equivalent to that of a SAM, in practice, they are typically found to be an imperfect substitute. It is important, therefore, in designing a database, to go beyond the confines of an (extended) IO system and T-accounts. SAMs provide an appropriate framework for doing so.     

An Aggregated Regional Economic Input–Output Analysis within a Fuzzy Environment

Abstract

Imprecision within economic input–output frameworks can be a problem, particularly when investigating the characteristics of defined industry sectors. This study undertakes an aggregated regional economic input–output analysis, within a fuzzy environment. The dearth of studies encompassing a fuzzy approach within input–output analysis largely concerns the problematic representation of imprecision. Results pertaining to the fuzzy output multipliers associated with each sector group are described, including possibilistic mean and variance; also identified is a specific ranking of the sector groups. Where appropriate, results are compared with those from a Monte Carlo simulation based stochastic analysis.     

Beyond Intermediates: The Role of Consumption and Commuting in the Construction of Local Input–Output Tables

Estimating intermediate trade using conventional non-survey methods produces biased results. This problem has led to a methodological recommendation that emphasizes the accurate estimation of intermediate trade flows. This paper argues for a qualification of the consensus view: when simulating input–output (IO) tables, analysts need also to consider spillover effects driven by wage and consumption flows. In particular, for metropolitan economies, capturing wage and consumption flows is essential to obtain accurate Type II multipliers. This is demonstrated by constructing an interregional IO table that captures the interdependence between a city and its commuter belt, nested within the wider regional economy.     

The First Two Eigenvalues of Large Random Matrices and Brody's Hypothesis on the Stability of Large Input–Output Systems

Bródy (1997) notices that for large random Leontief matrices, namely non-negative square matrices with all entries i.i.d., the ratio between the subdominant eigenvalue (in modulus) and the dominant eigenvalue declines generically to zero at a speed of the square root of the size of the matrix as the matrix size goes to infinity. Since then, several studies have been published in this journal in attempting to rigorously verify Bródy's conjecture. This short article, drawing upon some theorems obtained in recent years in the literature on empirical spectral distribution of random matrices, offers a short proof of Bródy's conjecture, and discusses briefly some related issues.     

Updating an Input–Output Matrix with Sign-preservation: Some Improved Objective Functions and their Solutions

This paper presents an easy-to-use method for updating input–output (IO) matrices with sign-preservation by combining Lagrangian multipliers and penalty functions. Biproportional methods such as the representative RAS are very simple and popular because a target matrix can be obtained simply by iterative computation. However, they cannot reasonably deal with matrices that include negative entries. Although a generalized version, GRAS, can do so, its objective function is questionable. In contrast, some non-biproportional methods such as those that take weighted or unweighted squared differences between the target and original matrix as objective functions can deal with negative entries, but it is difficult to guarantee the signs of entries. In this study, GRAS and some conventional objective functions were improved and their solutions for preserving the signs of entries are presented. Comparisons of applying these objective functions to a simple example show that both the Improved Normalized Squared Differences (INSD) function and the Improved GRAS (IGRAS) function yield a good target matrix and are close to each other; we suggest that INSD or IGRAS be used for updating IO transaction matrices in practice.     

Additivity of Deflated Input–Output Tables in National Accounts

Input–output tables deflated by chained prices indices are not additive over product rows. This paper discusses the reasons and suggests a remedy. The new method proposed is based on a distinction, in concept, between ‘real value’, on the one hand, and variation in ‘volume’, on the other. The first corrects for the monetary variation of the unit of account resulting from inflation, while the latter isolates the variation of one product price relative to the other products, caused by the forces of supply and demand on each individual commodity market. An example of the resulting growth analysis is compiled for the Dutch economy between years 1990 and 2000.     

Structural Change in Chile: 1960–90

This paper attempts to analyze compositional structural change in Chile, especially during the period around 1974–90, when the most overt ‘neo-liberal’ experiment was forced on the country's economy and society. The main conclusion is that, while the service sector has moved in the correct direction, setting up important industries for the dynamic development of the country, the manufacturing sector has not performed equally well. The manufacturing sector has significantly shrunk its most sophisticated base, and relies mostly on traditional manufacturing that grows sluggishly. Export expansion is in manufacturing still a small proportion of exports. The primary sector is still the main export earner, but has significantly diversified. It appears that the economy has not moved fast enough towards, and does not appear to be geared by, the type of exports that may sustain a dynamic industrial development, based on external markets.     

The monetary policy strategy of the Bank of England in 2020–21: An assessment

Excessive money creation during the Covid pandemic has resulted in Britain's worst episode of inflation since 1990–91. The backdrop to this failure of monetary policy is the Bank of England's aggregate demand/aggregate supply framework together with the Monetary Policy Committee's neglect of broad money. An alternative way to operate monetary policy is urgently needed. A significantly improved monetary policy outcome could be achieved by shifting from trying to steer the economy using interest rates and quantitative easing or quantitative tightening to reliance on the relative stability of income velocity (the ratio of nominal GDP to broad money) as a means of managing aggregate demand.     

Analysis of organizational commitment and work–family conflict in view of doctors and nurses

The present study investigates the relationship between organizational commitment and work–family conflict for medical doctors and nurses. Using canonical analysis on questionnaire, this relation has been tested distinctively through three sub-dimensions of organizational commitment listed: affective commitment, continuance commitment and normative commitment. Data collected from 766 (411 doctors and 355 nurses) individuals employed at seven state hospitals and three medical faculties of universities in Ankara. Analysis revealed that the relationship between organizational commitment scale and work–family conflict scale is weak and positive. Results suggest that the more committed the doctors and nurses are to the hospital they work for, the more work–family conflict they experience. On the basis of the sample information obtained in this study, it is possible to claim that if the employees are supported to establish a fair balance between their work and family lives in the guidance of these principles, a strong commitment to the organization will develop.     

Person–Organization Fit and Public Service Motivation in the Context of Change

This study examines public sector change, motivation and person–organization (P–O) fit in a stress context. The results provide empirical evidence that change initiatives produce change-induced stressors. However, change processes, including participation in change decision-making and the provision of change information, increase public service motivation, reduce change-induced stressors and ultimately improve P–O fit and job satisfaction. The results also depict that, in the context of change, public service motivation positively influences job satisfaction, with this relationship partially mediated by P–O fit. Implications for New Public Management and the importance of change processes for reducing workplace stress are discussed.     

The Productivity of Government Spending in Asia: 1983–2000

Leightner [The Changing Effectiveness of Key Policy Tools in Thailand. Institute of Southeast Asian Studies for East Asian Development Network, EAON Working Paper 19(2002)x0219-6417] develops a new analytical technique, named Reiterative Truncated Projected Least Squares (RTPLS), which produces 1/2 the error of OLS when omitted variables interact with the included independent variable. In this paper, RTPLS is applied to annual panel data on government spending and GDP from 1983 to 2000 for 23 developing Asian and Pacific countries. RTPLS produces estimates for the government spending multiplier for these countries and shows how omitted variables have affected these multipliers across countries and over time.JEL Classification: C13, E62, O23     

The impact of cultural differences on buyer–supplier negotiations: An experimental study

In today's global economy, an ever-increasing number of companies are dealing with international partners, instigating a need to understand the impact of cultural differences on business interactions. Using Hall's distinction of high- and low-context culture, this study investigates the direct and moderating effects of cultural differences in dyadic buyer–supplier negotiations. Theory is developed regarding the impact of culture on joint profits, juxtaposing Transaction Cost Economics and the Relational View. The theory is tested with a negotiation experiment. Participants, classified by their country of origin, negotiate prices and quality levels for three products. This study finds that cultural differences within the negotiation dyad reduce joint profits when compared to dyads of participants with similar cultural backgrounds. Cultural differences also moderate the impact of trust and bargaining strategy on joint profits. Overall, this study concludes that cultural differences, as encountered in day-to-day business interactions in global supply chains, significantly impact negotiation outcomes.     

Paid Parental Leave: An Employee Right or Still An Ideal? An Analysis of the Situation in Québec in Comparison with North America

Over recent years, parental leave policy in Canada has evolved quite considerably. Since 2001, Canadian employees have a right to a 1 year paid parental leave; those in the province of Québec have a better paid, more flexible regime. This paper first shows that Québec is somewhat of an exception in the North American context, with its inclusive mode of governance which contributes to positive policies in terms of family and childcare. This is due to a few elements: the recognition of a declining birthrate, but more importantly the significant involvement and actions of women’s advocacy organizations, in the context of an inclusive governance of family policy. We will defend the hypothesis that Québec has adopted a cumulative (or work–family balance) model in the field of work–family relation, while the US and English Canada tend to still resort mainly to a laissez-faire attitude, which to this day has limited employee rights in terms of parental leave, but also in terms of child care.
