Central bank decisions will be in focus next week, particularly in the wake of the central bankers' economic symposium in Jackson Hole.Indeed, so busy is European Central Bank (ECB) President Mario Draghi preparing for next week's meeting that he has been unable to attend the jolly-up in the Wyoming skiing resort."We regard it as very unlikely that the ECB will announce a yield cap or a very detailed strategy for bond buying. After the recent improvement in market sentiment, we thus see the risk of some investors being disappointed, potentially triggering a bit of risk-off," said Luca Cazzulani of UniCredit.The Bank of England's meeting offers the remote possibility of some drama. While the bank is odds-on to retain its key lending rate, minutes from the previous meeting of the Monetary Policy Committee indicated that there was some support for topping up the asset purchase (quantitative easing) pot, although the consensus was that the Bank should allow a bit more time to see how the recently introduced Funding for Lending Scheme pans out.Meanwhile, the Reserve Bank of Australia and the Bank of Canada are also expected to stand pat with their policies.On the corporate front, supermarket chain Morrisons reports interim figures on Thursday, which broker Jefferies thinks "are likely to bear the scars of weather challenges".Nevertheless, "self-help and ROCE [return on capital employed] discipline remain powerful attractions (the latter likely to lead to even greater capex [capital expenditure] scrutiny)," the broker suggests. "We anticipate self-help to have allowed for broadly unchanged underlying EBIT [earnings before interest and tax] margin (or a slight decline including the dilution from petrol sales). Crucially, we still forecast 8% H1 EPS [first half earnings per share] growth as buyback activity starts to reward shareholders," Jefferies added. "We expect Morrisons to outline good progress in its M-local trials and the preparation of a wider non-food online roll-out. Performance in the new fresh format is also likely to be reassuring in more affluent catchments. Despite this, we expect Morrisons' focus on maintaining industry-leading ROCE to likely result in reducing capital intensity (at this stage we estimate a £1.05bn peak in 2012/13), as the group balances a challenged trading backdrop with new growth opportunities, extending vertical integration and a stepped-up Southern expansion," Jefferies said.Tuesday has a bit of an agricultural feel to it, with animal genetics company Genus and veterinary healthcare company Dechra Pharmaceuticals set to update the market.Peel Hunt says emerging markets growth should be offsetting higher feed prices at Genus. It is forecasting a 15% improvement in profits, with strong growth across a number of emerging markets.The key issue currently is the rise in feed prices, Peel Hunt believes. "This will have a direct impact on Genus's feed costs of around £1m, but it will also affect its customers. Some customers may well struggle in the short term, but generally higher feed prices are good news for Genus as it accelerates the trend to industrialisation of the industry and reinforces the benefits of genetics in improving feed conversion," the broker predicts."We expect to hear more about plans in China, particularly with the announcement of the major JV [joint venture] with Besun, which will deliver genetics to 10m slaughter pigs when in full operation," the broker added.As for Dechra, the market is expecting profit before tax of £31.1m on revenue of £420.2m. Earnings per share are tipped to rise 19% to 37.03p, paving the way for the full-year dividend to be upped to around 12.16p from 10.97p last year.
