Book Description
1.1. Scope of the Book This book is a contribution to the area of "dynamic models of the firm". The motivation for this kind of research is the following: Empirical studies (e.g. Albach (1976)) have shown that the development of the firm over time can be divided into different stages. such as growth. stationarity and contraction. In order to understand and evaluate these stages in a proper way. it is important to develop a suitable theoretical framework. To that end. economists have applied dynamic mathematical techniques. such as optimal control theory. calculus of variations and dynamic programming to design and analyse dynamic models of the firm. In this way. the economic theory of the firm is extended to a dynamic context. Within the field of the dynamics of the firm this book - develops a general investment decision rule. based on the concept "net present value of marginal investment". which is applicable in deterministic dynamic models of the firm; - studies the influence of adjustment costs of investment on optimal dynamic firm behavior; - extends the stochastic dynamic theory of the firm by connecting it with a dynamic version of the Capital Asset Pricing Model. Before elaborating on "the dynamics of the firm". we first review the subject of net present value in the classical analysis.

The Core of Economies with Asymmetric Information

Book Description
and should therefore constitute a part of every area of economic 3 theory. The spectrum covered by information economics today ranges from Stigler's search theory4 to industrial economics, including oligopoly theory, innovation, as well as research and develop 5 ment. However, the area information economics is most closely connected with is the theory of optimal contracts, mainly ana 6 lyzed in principal-agent models. Contract theory deals primar ily with the question of how optimal arrangements (contracts) for the purchase and sale of commodities and services between two or more agents should be structured. In these models, it is often assumed that the parties to the contract are informed differently or asymmetrically about relevant variables (e. g. the health of one party in the case of insurance contracts, or the effort in relation to employment contracts). As a result of this asymmetric in formation, phenomena such as moral hazard, adverse selection, signaling, and screening may arise. Frequently, results from con tract theory are referred to when making statements about the effects of asymmetric information on an economy. Models of this kind are often used to explain phenomena such as fixed wages or unemployment, among others. 7 However, such conclusions must be treated with caution for two reasons. In the first place, in these models, a contract (explicit or implicit) is determined by the solution of an optimization prob lem.

The Visible Hand

ISBN: 3642467539
Category : Business & Economics
Languages : en
Pages : 141
Book Description
In the last decade highly innovatory developments have taken place in theoretical economics. The new focus of interest seems to be twofold: Firstly, nonlinear models for dynamic processes of the economy are constructed to extend the scope of linear models for tlle stationary euqilibrium state; and secondly a new approach is made to solve the everlasting problem of the relation between micro-and macro-economics. The interdisciplinary field of synergetics is deeply involved in this evolution. The author has made a remarkable contribution to both foci: His application of synergetic concepts to the theory of business cycles combines a partial solution of the micro-macro-problem, namely the modelling of the macro-economic effect of the decisions of investors, producers and consumers, with the natural introduction of nonlinearities. The arising new business cycle theory can on the one side be validated by empirical evidence and on the other hand the typical behavior of nonlinear dynamic systems including the transition to deterministic chaos can be clearly demonstrated. The hope is justified that the model presented in this book is a fw·ther important step in reaching a new level of the quantitative comprehension of dynamic phenomena in the economy. Stuttgart, June 1991 Prof. Dr. Wolfgang Weidlich Foreword It is the author's objective to explain macroeconomic processes on the basis of micro economic decision-making behaviour. In order to achieve this goal, the concept of synergetics is presented as a method of describing dynamic phenomena in multi-com ponent systems with cooperative interactions between their elements.

Inventory, Business Cycles and Monetary Transmission
Author: Riccardo Fiorito
Publisher: Springer Science & Business Media
ISBN: 3642468063
Category : Business & Economics
Languages : en
Pages : 288
Book Description
Inventory changes constitute in all countries a small fraction of the Gross National Product but also a major source or an indicator of cyclical fluctuations. In this volume both possible ways of propagation are investigated by examining in the first part what macroeconomists have learned and still have to learn about inventories in the light of statistical definitions and problems. In the second part, the role of monetary shocks in propagating business cycles is considered through liquidity effects and in relation to inventory adjustment. A possible linkage between inventory and labor market is shown. Finally, new evidence and theoretical insights are provided on the linear-quadratic inventory model and its ability to discriminate econometrically among competing firm behavior.

Price Stabilization on World Agricultural Markets
Author: Bernd Lucke
Publisher: Springer Science & Business Media
ISBN: 3642467822
Category : Business & Economics
Languages : en
Pages : 280
Book Description
International commodity markets have traditionally attracted the attention of economists, econometricians, and policy makers especially in and following politically tumultuous times. For instance, the primary commodity price boom of 1973/74 and the subsequent period of highly volatile world market prices initiated increased research on commodity markets which quickly focused on possible price stabilization schemes, particularly on buffer stocks. Simultaneously, the issue clearly advanced in priority on the political agenda, such that the United Nations Conference on Trade and Development (UNCTAD) proposed an "Integrated Program for Commodities" (IPC) intended to stabilize the world market prices of ten so-called "core commodities"l (UNCTAD (1974, 1976a), Behrman (1979)). Many developing nations welcomed the IPC almost enthusiastically, but it did not receive more than lukewarm support by major industrialized countries, apparently due to the experience with some thirty international commodity agreements past World War II2. Critical evaluations have, among others, been presented by McNicol (1978), Gordon-Ashworth (1984), and Macbean & Nguyen (1987). The most detailed of these studies is Gordon-Ashworth's, who concludes that "on balance ... the performance of international commodity agreements has been too unreliable and their distributive effects too uneven to secure the development goals that have been set" (1984, p. 284)3. Consequently, the IPC turned out to be quite controversial a topic on the UNCTAD's 1976 meeting in Nairobi and has not been able to gain any impetus since. lThese were cocoa, coffee, copper, cotton, jute, rubber, sisal, sugar, tea, and tin.

Resource-Constrained Project Scheduling
Author: Arno Sprecher
Publisher: Springer Science & Business Media
ISBN: 3642483976
Category : Technology & Engineering
Languages : en
Pages : 157
Book Description
Within a project human and non-human resources are pulled together in a tempo raray organization in order to achieve a predefined goal (d. [20], p. 187). That is, in contrast to manufacturing management, project management is directed to an end. One major function of project management is the scheduling of the project. Project scheduling is the time-based arrangement of the activities comprising the project subject to precedence-, time-and resource-constraints (d. [4], p. 170). In the 1950's the standard methods MPM (Metra Potential Method) and CPM (Cri tical Path Method) were developed. Given deterministic durations and precedence constraints the minimum project length, time windows for the start times and critical paths can be calculated. At the same time another group of researchers developed the Program Evaluation and Review Technique (PERT) (d. [19], [73] and [90]). In contrast to MPM and CPM, random variables describe the activity durations. Based on the optimistic, most likely and pessimistic estimations of the activity durations an assumed Beta distribution is derived in order to calculate the distribution of the project duration, the critical events, the distribution of earliest and latest occurence of an event, the distribution of the slack of the events and the probability of exceeding a date. By the time the estimates of the distributions have been improved (d. e.g. [52] and [56]). Nevertheless, there are some points of critique concerning the estimation of the resulting distributions and probabilities (d. e.g. [48], [49] and [50]).
