Measuring progress towards sustainable development requires appropriate frameworks and databases. The System of Environmental-Economic Accounts (SEEA) is undergoing continuous refinement with these objectives in mind. In SEEA, there is a need for databases to encompass the global dimension of societal metabolism. In this paper, we focus on the latest effort to construct a global multi-regional input-output database (EXIOBASE) with a focus on environmentally relevant activities. The database and its broader analytical framework allows for the as yet most detailed insight into the production-related impacts and "footprints" of our consumption. We explore the methods used to arrive at the database, and some key relationships extracted from the database.

This paper is divided into four distinct sections. 1. An explanation of the meaning of input/output analysis, especially the derivation and significance of the table of direct and indirect requirements. 2. An outline of the decisions taken in constructing the West Malaysian 1960 transactions table from a set of National Accounts - especially the treatment and valuation of imports and exports; producer versus purchaser price valuation of transactions; and problems of inconsistent and incomplete double entry records. 3. An explanation of the method of forecasting from input/ output tables. This includes discussion of: a. A method of estimating aggregate demand for Malaya for 1970. b. A method of projection of value added for each sector, 1970. c. The likely stability of the input coefficients over time. 4. Results; a. Differences between the 1960 and 1965 table projections due to changes in Leontief inverses and value added coefficients over time, as the economy undergoes change. b. Comparison of the table projections with the First Malaysia Plan projections: i. Are the Plan projections likely to be reached in 1970? ii. Why are some of the table projections so inaccurate? The paper concludes that 1. The projections from the 1965 input/ output table are generally superior to those from the 1960 table. 2. Under conditions of structural change, even 5 years is too far ahead to expect input/output analysis to yield accurate projections for most sectors. / Arts, Faculty of / Vancouver School of Economics / Graduate

Yes / This article examines the potential benefits of solving a stochastic DEA model over solving a deterministic DEA model. It demonstrates that wrong decisions could be made whenever a possible stochastic DEA problem is solved when the stochastic information is either unobserved or limited to a measure of central tendency. We propose two linear models: a semi-stochastic model where the inputs of the DMU of interest are treated as random while the inputs of the other DMUs are frozen at their expected values, and a stochastic model where the inputs of all of the DMUs are treated as random. These two models can be used with any empirical distribution in a Monte Carlo sampling approach. We also define the value of the stochastic efficiency (or semi-stochastic efficiency) and the expected value of the efficiency.

A model is developed to identify the optimal capital expansion decisions for producers of s consumable products. The model features an optional selection of corporate level in a product tree hierarchy and a choice of several optimizing objective functions. The model assumes that intermediate product demand is directly dependent on demand for consumable products. Intermediate product demands are derived from demand for consumable products using a product tree similar to a bill of materials. Restrictions exist on the productive capacity of all products in the product tree, and interdependences exist between producers of the various products. Likewise, the availability of labor limits production capacities for all products in the product tree. The capital available for the capacity expansions can either be capital equity or corporate debt. The model identities the expansion strategy which optimizes the chosen economic objective function. A case study is analyzed with linear programming software to determine the optimal expansion strategy for a tire manufacturer given a hypothetical market demand for automobiles. / Master of Science

The increasing demand for mineral-based resources that face supply risks calls for managing the supply chains for these resources at the regional level. Cobalt is a widely used cathode material in lithium-ion batteries, which form the major portion of batteries used for renewable energy storage - a necessary technology for electrifying mobility and overcoming the challenge of intermittency, thus making renewable energy more reliable and energy generation more sustainable. This necessitates understanding cobalt's supply risks and for the Untied States, identifying sources of cobalt available for future use via recycling or mining. These needs are addressed in this work using single and multiregional input-output (MRIO) analysis in combination with graph theory. An MRIO-based approach is developed to obtain the trade network of cobalt and offer a more expedient way to identify potential critical material sources embodied in commodities made domestically. Commodities containing cobalt were disaggregated from two input-output (IO) models and the trade structure of cobalt at the national and state level was observed and compared. The significance of identified key sectors is measured according to several criteria and differences in sectors highlighted in the national versus subnational networks suggests that analysis at the two regional aggregation levels provides alternative insights. Results from mining the IO networks for cobalt highlight the geographical distribution of its use and industries to further investigate as potential sources for secondary feedstock.
