THE CANADIAN AGRICULTURAL PRODUCTION FUNCTION

Fitting production junctions has become little more than a quantitative exercise for economists. They have been computed for virtually every phase of the real economy with a considerable degree of accuracy. One of the areas that has continued to present some difficulties in this regard is agriculture. The difficulties have been of such magnitude in the United States that an accepted technique has been to proceed directly to the supply function. The authors suggest that the above procedure need not be followed in the Canadian case. They fit a five variable linear multiple regression relation to Canadian agriculture which fits the industry quite Well in terms of explained variation and adherence to the assumption of the analysis. This is substantially in contrast with the U.S. experience indicating a substantial difference in either data, the agricultural industries, or both. An aggregate production function of use for policy formulation purposes has been made available for the Canadian case. ?adjustage des fonctions de production ne devient guére que de ?eiercice quantatif pour les économistes. Elles ont été calculées avec un degré de précision notable pour presque toute phase de ?économie réelle. Vn des domaines qui continuent à présenter des difficultés à ce sujet est ?agriculture. Les difficultés ont été?une telle ampleur aui Etats-Unis qu'une technique accreditée est de se rendre directement à la fonction ?offre. Les auteurs suggérent qu'au Canada on n'est pas obligé de suivre le procédé ci-dessus mentioné. Ils ajustent une relation linéaire de régression multiple à cinq variables à?agriculture canadienne. Elle s'ajuste à?industrie assez bien quant à la variation expliquée et à?appui des présomptions de ?analyse. Le contraste entre ces faits et ?expérience américaine indique qu'il y a une différence considérable ou des donnees ou des industries agricoles ou les deux. On met à la disposition de ?investigateur canadien une fonction de production globale qui est utile à formuler des politiques.     

GROWTH AND INCOME POVERTY IN LATIN AMERICA AND THE CARIBBEAN: EVIDENCE FROM HOUSEHOLD SURVEYS

This paper provides evidence on growth and income poverty in Latin America and the Caribbean (LAC). Results are obtained by processing microdata from household surveys of 18 LAC countries covering the 1990s and early 2000s. Over this period the LAC economies experienced heterogeneous patterns of growth and poverty changes. Most countries in the region had a rather meager performance in terms of poverty reduction. Episodes of positive, significant and unambiguously pro-poor income growth have been rare in Latin America.     

COMMON STOCHASTIC TRENDS AMONG THE CYPRUS STOCK EXCHANGE AND THE ASE,LSE AND NYSE

Common stochastic trends among major international stock price indices have been an intensively analysed issue mainly as a result of the 1987 stock market crash and the need for policy coordination in financial markets. This paper investigates the existence of common stochastic trends among an emerging equity market, the Cyprus Stock Exchange, and three mature equity markets, namely the Athens Stock Exchange (ASE), the London Stock Exchange (LSE) and the New York Stock Exchange (NYSE).     

Biased procurement auctions

In a complex procurement a buyer may consider biasing the auction rules in order to account for differences in product characteristics offered by the sellers. This paper studies the gathering, disclosure and use of information about this bias. While we also describe the optimal procurement auction in our setting, the main focus of the paper is on the case where the buyer does not have commitment power. We find that without commitment full disclosure of the buyer’s preferences is optimal. Furthermore, lack of commitment distorts the buyer’s incentives to learn about its preferences: unlike the commitment case, without commitment the value of this information can be negative.

On the monetary-macro dynamics of Colombia and Mexico

This paper investigates the dynamic interrelationship among money growth, inflation, and output growth for Colombia and Mexico on the basis of implementation of a vector autoregression methodology. The evidence for Colombia generally shows autonomous output growth and money growth behavior, and an important role for money shocks in accounting for variations in inflations. A different pattern of results emerged for Mexico: there are strong two-way feedbacks among money growth and inflation, and a less autonomous output growth behavior than in Colombia.

This note reviews some results on aggregating discrete‐time long memory processes, providing a formula for the spectrum of the aggregates that considers the aliasing effect.     

Adaptive-regressive expectations and the price level: A reformulation

In a recent paper, Frenkel (1975) presents an adaptive-regressive scheme of expectations as applied to the inflation rate. While the rationale for the scheme is the presence of expectations concerning the price level, Frenkel's construction does not specify such an expected price level, but only a short-run (instantaneous) and a long-run expected inflation rate. It is shown here that, even though such a specification yields reasonable results for certain important kind of policy changes, it is not robust enough so as to yield equally reasonable outcomes for other type of changes. This paper presents a specification of the expected price level (and, consequently, of all future expected inflation rates) which is not subject to those shortcomings and which seems to reflect in a better manner the basic economic idea behind the scheme.
