this article analyses the effects of foreign exchange commitment and exchange rate unification policies on iran’s non-oil exports during the last three decades. in addition, the effects of these policies on non-oil exports have empirically been estimated. for this purpose, an export supply model was estimated using the econometrics technique of auto regressive distributed lag (ardl) and reliabl...

This study aims to examine the effect of investment and consumption spending on Indonesia’s economic growth. The data used is the quarterly time series data from the first quarter of year 2003 to the fourth quarter of year 2013, comprising consumption spending, investment and economic growth. For the purpose of analysis, the autoregressive distributed lag (ARDL) model is used. The result of the...

Langenberg and Srinivasan (1981) proposed two procedures for the choice between two medical treatments. They assumed that there is a time lag between the administration of the treatments and the availability of the responses. The two procedures are suggested for dealing with patients who arrive during the waiting period, caused by the lag, between the trial and treatment stages of the model . T...

Rubber is one of the major plantation crops cultivated in Sri Lanka. It gives an environmental service apart from its economic potential. To have a continuous supply of rubber, it is vital that the balance between mature and immature rubber stands be maintained in the long run. In order to do this, at least 3% of the total area under rubber needs to be re-planted annually. However, in the recen...

This paper wnsiders the use of the polynomial distributed lag (PDL) Cechnique when the lag length is estimated rather than tixed. We focus on the case where the degree of the polynomial is fixed_ the polynomial is mnstrained to be zero at a Certain lag length q. and q is estimated along with the other parameters. We extend the traditional PDL setup by allowing q to he real-valued rather than in...

I study a problem of repeated moral hazard in which the effect of effort is persistent over time: each period’s outcome distribution is a function of a geometrically distributed lag of past efforts. I show that when the utility of the agent is linear in effort, a simple rearrangement of terms in his lifetime utility translates this problem into a related standard repeated moral hazard. The solu...

This paper is concerned with the problem of measuring market response to a "communications mix" -the various means which a firm employs to transmit sales messages to potential buyers. Distributed lag models are applied to time series data for an ethical drug to estimate the short-run and long-run effects on market share of expenditures made for journal advertising, direct mail advertising and s...

This paper assesses the relationship among energy consumption, financial development, economic growth, industrialization and urbanization in Tunisia from 1971 to 2008. The autoregressive distributed lag bounds testing approach to cointegration and Granger causality tests is employed for the analysis. The result confirms the existence of long-run relationship among energy consumption, economic g...
