The study objectives include examining the prevailing economic situations; comparing the producer and consumer prices during the two eras; and evaluate the effect of the two marketing board eras on cocoa production. Time series data for the period 1966 to 2009, were sourced from Cocoa Research Institute, Ibadan, FAOSTAT and Annual Bulletin of Statistics of the National Bureau of Statistics. Descriptive statistics, Trend analysis and Co-integration Analysis were used to analyse the data. The result revealed that that there is trend in the cocoa production during the marketing board era as compared to the post-marketing board era. This is attributed to the increase in the prices experienced in post marketing board era. The study also established that during the marketing board era, prices and marketing margins affected the production of cocoa. The marketing board era had positive impact on the cocoa production although the trend analysis revealed the post marketing era has higher production. Thus the study recommends that Government and cocoa farmers should learn from the price stabilization mechanism of marketing board era. In order to have a sustainable economic development, the government should move away from direct involvement in running the economy such as the marketing of cocoa. INTRODUCTION Nigeria though depends largely on the oil industry for its budgetary revenue, is still predominantly an agrarian society. The agricultural sector in periods immediately after the independence performed outstandingly these roles, to such an extent that the regional development witnessed during that period was attributed directly to the sector. During the early nineteen-seventies, Nigeria experienced growth rates of 8% -10% per annum, while the increase in agricultural production declined to around 4% per annum towards the end of the 1

decade. The slow growth continued into the nineteen-eighties, with output rising by only 3.4% in 1981 and by 2.7% in 1982. The effects of drought and the government's austerity program resulted in severe 9.4% fall in agricultural output in 1983. However, a succession of good harvests, higher producer prices, reductions in cereal imports and a resurgence of public and private investment in crop production resulted in a sharp recovery in production (FAO, 2001). Prior to the oil boom of the mid- 70s, Cocoa was the highest foreign exchange earner in Nigeria and according to Olatunbosun and Olayide (1972) and has remained a valuable crop among agricultural commodity of the country (ogunleye and Oladeji, 2007). In recent years, more and more of the raw beans are utilized within Nigeria for the manufacture of various chocolate and confectionery products, thus boosting industrial growth and generating employment and income (Awopetu, 2001). Cocoa exports have also been a significant contributor to economic growth of Nigeria and as at 1993, according to Titilola (1997), Nigeria was the fourth largest producer of Cocoa in the world, ranking after Ivory Coast, Brazil and Ghana. Cocoa accounted for over 90 percent of non-oil exports in 1985. Producers price tripled between the 1985 and 1986 harvest and the 1986 main harvest after the Cocoa Board had previously set prices close to world prices at the official exchange rate. The reorganization of the marketing boards in 1976 gave rise to the creation of seven different commodity boards. They are cotton, grain, palm produce, groundnut, rubber, root and tuber crops boards (Idachaba and Ayoola, 1992). Until June 1986, when the commodity boards were scrapped, the marketing and exporting of agricultural produce Nigeria was mainly monopolized by the commodity boards. One of these boards is the Nigeria cocoa board for the cocoa produce in Nigeria. Prior to introduction of Structural Adjustment Programme (SAP) in 1986, Joshua (2001) specified that Nigerian cocoa beans were exported exclusively by Nigerian Cocoa Board (NCB). In terms of mode of operation, the board had the statutory responsibility to procure cocoa beans locally and export. In doing so, it created 2

and maintained a structure of local buying agents (LBA) for the sole aim of aggregating cocoa beans from farmers in the producing areas.the boards appointed License Buying Agents (LBA) who could either be companies, individuals or cooperative societies to purchase, bag, store, grade and transport to the boards port stores. According to Kolawole (1971), the operations of the marketing board era were criticized on the grounds that the system had failed to provide incentives to farmers to increase production. The first progress report on the current 1970/1974 development plan indicates that the system (marketing board era) as presently operated discourage increase efforts and production by the farmers. The stagnation in the output and export of some cash crops is attributed to the marketing board system. As a result of the inefficiencies in the commodity boards system and following structural changes in the Nigeria economy in the mid-eighties, the marketing board structure was abolished by the Federal Government of Nigeria in 1986 and this gave rise to free market operations. Under the new marketing system, Farmers sell to private entrepreneurs who performed various marketing functions in the Nigeria cocoa economy. Consequently, the prices at which cocoa and other cash crops farmers in Nigeria are able to sell their produce to a large extent now depend on how they respond to both local and global demand in the cocoa industry (Olubanjo et al, 2009). The principal objective of the new policy (post marketing board era) which started form 1988 is to increase the production of agricultural exports.the purpose instrument for achieving this objective is an increase in the proportion of world price paid to producers. According to the federal government, the reasons for these changes is primarily to offer relatively high producer prices to our farmers and encourage them to increase their production of cocoa (Kolawole, 1971). Yet the production and export of cocoa is still stagnant and producer income is still relatively low affecting the sustainability of the county economic development, hence there is a need for the assessment 3

of cocoa marketing. Considering the above, there is need to compare the marketing board era and the post marketing board era. This study therefore examine the economic and the prevailing situations of both marketing board and post marketing board era, compare the producer price and the consumer price of marketing board era with the post-marketing board era and evaluate the effect of the marketing board eras on cocoa production. METHODOLOGY The study was conducted in the Federal Republic of Nigeria. The set of data for this study was time series data from secondary sources. The data collected were for the period of 1966 to 2009. This data were obtained from Cocoa Research Institute; Ibadan, FAOSTAT, annual bulletin of statistics on cocoa and relevant published materials such as journals, books e.t.c. Three major tools of analysis were employed in this study. They are descriptive statistics, trend analysis and co-integration analysis. Trend analysis was used to compare the producer price and the consumer price of marketing board era with the post-marketing board era. Estimation of the trend line used in this study involves the use of least square method used to decide whether there is a statistically significant trend in price over time in the two eras. The Ordinary Least Square (OLS) equation is; Yt = α + βt + et, t = 1,2,,44 Where: t = time, Yt = trend values with respect to time (t), Et =error term, which is assumed to be identically and independently distributed with mean zero and constant variance, that is et ~ NIID (0.σ²). The test statistic is used as a measure of significance of trend. In fact, this test statistic is used to test the null hypothesis, : There is no monotonic trend. P-value is the probability which determines the appropriateness of rejecting the null hypothesis in a hypothesis test. P-values range from 0 to 1. The commonly used significance level is 4

. If the P-value is less than the, the null hypothesis is rejected. In this case, the null hypothesis is that there is no trend in the data. Hence, a P-value less than 0.05 shows that the trend is significant. So the smaller the P, the more significant the trend. Co-integration process evaluates the effect of marketing board eras on cocoa production. This process integrates short-run dynamic with long run equilibria (Maddala, 2001). Co-integration analysis as it was developed by Granger (1981), elaborated in Engle and Granger (1987), adapted and used by Obasi (2007) and Olubusoye and Oyeromade (2008) firstly involves the test for unit root or stationary test. The augmented Dickey-fuller (ADF) test was used for the test. The ADF F-ratio critical value was used to make decision on the stationary of the variables. The Johansen technique was used to test for co-integration in the model. Johansen technique was used not only because it is vector auto regressive based but because it performs better in multivariate model. The model is shown as follows: LY t = β 0 + β 1 LX 1t + β 2 LX 2t + β3 +LX 3t + e t Where; Y 1 = output (cocoa production), X 1 = price, X 2 = export rate, X 3 = market margin, t = Time e t = error term.the error term was tested for unit root for reconfirmation of co-integration. RESULTS AND DISCUSSION DESCRIPTIVE STATISTICS The table below describes the producer price, the consumer price, export rate, output and market margin with their corresponding minimum, maximum, mean and the standard deviation values for the overall data. It shows the various levels of marketing board era and post marketing board era base on the producer and the consumer prices. 5

It is also stabilized for the years 1977, 1978, 1980, 1981and 1982 at N1300. From 1982 to 1987, the stability begins to reduce and the prices increases drastically. The price peaked around 1973 to 1985. 1990 1995 2000 2005 2010 Year3 Figure 2: Price of cocoa during Post-marketing board era 7

Prices here are not stable in between years but the price reached the peak in 2006 at the rate of N2, 431,785. This may be due to political changes because the government as at that time introduced SAP and the exchange rate changed which led to the high value of dollar and thus has a nominal high increase in the price of cocoa.

Comparing the two trends; Marketing and post marketing board era, it was discovered that there is no trend in the post marketing board era and there exist trend in the marketing board era. This is due to increase in the price of post marketing era over the years. 10

But at first differencing, they all became stationary at 1%. The differencing is needed in order to avoid having a spurious regression. Since the differenced variables are stationary, there is cointegration between the variables; this means that there is a long run relationship between the output, era and export rate. The other two variables that does not exhibit unit root at the level that it that are stationary are therefore lagged to also avoid spurious regression. After lagging the lagged values of price and market margin positively affect the output of cocoa over the marketing board eras.

Only one of the CI equations was chosen. The CI equation chosen was based on the conformity of the coefficients with the 11

economic theory and its statistical significance. From the equation all the independent variables are significant in determining output (cocoa production) in Nigeria during the period studied. X 1 is significant at 1%, X 2 is significant at 10%, X 3 is significant at 1% and X 4 is significant at 5%. Therefore, the variables are positively co-integrated because the independent variables determine the output of cocoa production at different percentages as mentioned above respectively. The marketing board eras therefore have positive effect on cocoa production.

That is the previous rate has positive impact on the present rate. The lagged change in export rate has negative effect on the output rate. The era of the marketing board, price and market margin are all significant also1%. The implication of this is that the marketing board era has positive impact on the output of cocoa than the post marketing board era. Although from the descriptive statistics the maximum output of the marketing board era is lower than that of the post marketing board era, it still does not mean that post marketing board era is better than the 12

marketing board era. The standard deviation of the marketing board era is more than that of the post marketing board era. This shows that the marketing board era determines cocoa output positively. CONCLUSION AND RECOMMENDATIONS. The study also establishes that marketing board era, prices and marketing margins affect the production of cocoa production. It was also discovered that though not significant, export rate affects the output of cocoa negatively. The marketing board era has positive impact on the cocoa production although the trend analysis revealed the post marketing era has higher production. Based on the analysis of this study, there are opportunities to be developed as a nation if the cocoa farmer focuses on maintaining a relatively increasing cocoa production as cocoa is one of the non-oil export commodity in Nigeria. Cocoa production (output) can be increased if there is stability of prices. Cocoa production can also be affected by the export rate and market margin. Thus the study recommends that Government and cocoa farmers should learn from the price stabilization mechanism of marketing board era but that the exploitative factors of its should not be emulated to allow the farmers to experience and reap the benefit of higher output. The government should move away from direct involvement in running the economy such as the marketing of cocoa. To this end, programs and policies that will help to increase cocoa production should be incorporated, well organized and monitored. Likewise, programs and policies that will help to check and stabilize the price of cocoa output should be employed. 13
