Based on preliminary estimates released Tuesday by the European office of statistics to Eurostat, the euro area recorded no growth (0.0%) during the first three months of the year, after a decline in GDP of 0.3 % last quarter. This figure, better than expected by analysts (-0.2%), allows the euro area narrowly escaped the recession, which is recognized when GDP shrinks for two consecutive quarters. But mostly he hides significant disparities between countries in the euro area: while Germany saw its GDP grow by 0.5%, exceeding all expectations, thanks to exports and consumption, France experienced no growth (0%) and Italy sank into recession (-0.8%).

The Netherlands has also experienced poor performance (-0.2%). As for Greece, she recorded a fall in GDP of 6.2% in the first quarter, according to preliminary official estimate.

These differences show that "the region remains highly dependent on Germany," said Jennifer McKeown of Capital Economics. "A big thank you to progress better than expected German GDP," added Martin Van Vliet of Ing.  

Figures released Tuesday should at least contribute to the debate on growth in Europe, a topic that has emerged slowly while facing austerity, especially under the leadership of French President Francois Hollande.

The latter reiterated its position on the issue during his inauguration speech Tuesday morning at the Elysee Palace. "To our partners, I will propose a new pact that will combine the necessary reduction of public debt with the necessary stimulus," he said. "To overcome the crisis that afflicts it," he said, "Europe needs projects, it needs solidarity, it needs for growth."

The subject should be central to its discussions on Tuesday afternoon in Berlin with Chancellor Angela Merkel, the main advocate of fiscal discipline in Europe, who reluctantly welcomed his proposal to add a growth component in the European budgetary treaty. How to revive European growth will also constitute the main theme of the dinner which will bring together European leaders in Brussels on May 23

The Italian leader, Mario Monti, proposed last week to "unite people of good will" to ensure that it is "compatible" with fiscal consolidation. He is scheduled to meet Tuesday in Brussels with European Commission President Jose Manuel Barroso, whose proposals for growth (increased resources for the European Investment Bank, finance major European projects, tax on financial transactions , better use of EU funds) are widely shared by Mr. Holland.

European leaders will anyway have to be proactive to defy predictions of analysts. To Martin Van Vliet, there is "no evidence of strong and sustained economic rebound on the horizon for the euro area".

As for Howard Archer, IHS Global Insight, thinks that "a contraction of GDP will likely be on the menu in the second quarter." Although a gradual return to growth is expected later this year, "a further escalation of the debt crisis, not counting an output of Greece (the euro area), could derail the expected recovery," puts cautioned Mr. Van Vliet.

GSK's offer, to 13 dollars per share, represents a premium of 81% over the closing price of 7.17 dollars for action Human Genome Wednesday night, but the U.S. group believes it does not reflect its intrinsic value.

In pre-market Human Genome soared over 100% to trade at just over $ 15, a sign that the market is betting on a bidding war in this new battle that promises to within a pharmaceutical industry recently marked by a wave of consolidation. 

Human Genome, American laboratory that specializes in gene isolation and identification of their function in the development of new drugs, said banks have mandated Goldman Sachs and Cre Swiss said the counselor.

First British pharmaceutical company, GSK said he was disappointed in a statement of rejection of his offer without discussion. The group confirmed its offer, stating that the proposed price of $ 13 would be paid in cash.

He also said to expect the transaction provides for the realization by 2015 at least $ 200 million of cost synergies, and that it will be accretive to from 2013.

If GSK has been a tendency in the past not to buy out partners with whom he works, the rumor of an offer to GSK on its U.S. partner ran long, the two companies already collaborate ; over several treatments, including Benlysta, the first new drug against lupus in more than half a century.

Navid Malik, analyst at Cenkos Securities, indicates that GSK extremely knowledgeable Human Genome and must point to a potential value in excess of one Benlysta. 

Both groups are also working on a project called darapladib treatment of heart, now in the third and final phase of experimental tests.

If product development is going to an end, analysts see it as a "blockbuster" possible multi-billion dollar per year, although the molecule is also accompanied by a high level of risks.

A banker in the health sector considers the offer of generous and GSK believes that certain shareholders of Human Genome could accept it.

Others, however, prefer to wait an increase of the price. They know the appetite of big pharmaceutical companies for biotech in their search for new growth after the expiration of patents on several of their blockbuster drugs.

After the delirium, appeasement. The Paris property prices are going down, all professionals are unanimous, including notaries. The period October 2011 to January 2012, the price per m2 of housing in Paris and has declined slightly, to 8340 euros/m2, instead of 8370 euros previously. This represents a 0.3% decrease. The capital rappoche so the trend throughout the Paris region (-0.6% over the same period). Certainly, the decline is limited, but it denotes with previous years of sharp increase. The notice of Sébastien de Lafond is President of MeilleursAgents.com.

What do we see on the Paris market?

The Paris market has long been an exception to the French property market. If you look at the figures for previous years, between the third quarter 2009 and third quarter 2010, prices rose by 13.8% in Paris. And in 2011, the increase was 15% for old apartments. Result, the price per m2 in Paris reached 8,344 euros. The left bank has skyrocketed. First explanation: the exploding demand, strong excess relative to supply, fueled by several factors: historically low interest rates, a preference for stone instead of the stock market, investors have never been as many ( 26% of buyers, against 16% in all of France). All in a context of shortage of housing. In Ile-de-France, we need 70,000 homes a year to meet demand, then we do not built for that half hour. Another factor increase: foreign demand, which influences prices in many districts, the first in the eighth arrondissement, the 16th-but also and especially on certain types of property high-end or central ashore. This is a customer with high purchasing power, thus likely to distort the market structure high-end. Still, foreigners account for barely 5% of buyers.

The price on the Paris market have they peaked?

Today, no doubt, this market is cooling and has been since last July. The last six months, prices in Paris intra muros lost 3.5%, even lower in the inner suburbs and it is around 5% in the outer suburbs. Similarly, the transaction time is 50 days in Paris twice a year ago and 40 to 80 days in the Ile-de-France. In nine out of 10 districts, prices declined in the fourth quarter of 2011 versus the third quarter of that year. The volume of property transactions fell 15% in Paris and 20% in small and large crown.

How can we explain this decline?

On the one hand, we lost 30% of buyers from last year. First reason: the prices in Paris and the Ile de France have reached very high levels. For proof, from June 2009 to June 2011, they increased by 29%. Given this rise, many buyers say "stop". Another reason to be bullish: the banks are much more restrictive in terms of access to mortgages since the Greek crisis. Now, exit the small arrangements if you are on probation or if you have a low intake. Have a permanent and present a contribution of 5 to 10% is the rule in any bank. Moreover, the monthly credit shall not exceed 1/3 of disposable income of the borrower. Finally, we lost about 10% of buyers due to the suppression of PTZ + in the former, which was included last year in 40% of real estate transactions in the former.

On the other hand, the decline was due to the 20% of sellers and less. The sale is generally followed by a purchase. But in an economic context is not conducive to going into debt over twenty years, coupled with a fear of the future and an uncertain economy, people are more cautious. Finally, the election deadline pushes the real estate project.

The decline in the market Ile can it continue?

We announce a drop of about 5% to 10% of Paris and the Ile-de-France at least until June But this drop will not be sustainable if rates continue to decline as is currently the case in most banks. Because if interest rates fall, prices rise. However, if they increase, prices are revised downwards. This hypothesis is highly possible with the economic crisis in Spain today. The rate of OAT, (the rate at which borrows France over 10 years) may increase. However, if lending rates rise by 1%, prices could fall by 15%.

Beyond these predictions, the basic problem remains, we have a deficit of housing particularly marked in the Paris region market. Given migration, birth rates, etc.., Demand for the stone is too large to attend a substantial fall in prices in Paris, in small and large crown. The new housing shortage keeps prices. It is for this reason that the drop is, and will only be on if the new housing construction remains at this level. Buyers should not expect a substantial fall in prices. Today the market is experiencing a slight decline. This is a good time to buy in Ile-de-France.

But who can still buy in Paris?

In the capital, buyers under 30 have almost disappeared but the secondo-time buyers drive the market. Those buy for resale and are immunized against rising prices. We defined three categories of buyers. High-income couples, 30 to 40 years, may in turn seek apartments from 60 to 100 m2 through debt of 20 to 25 years. The secondly-time buyers who bought there over five years and can make a nice capital gain are now the most dynamic part of the application. But they are experiencing shortages of goods. Finally come the investors with a medium-to long term.

The number of job seekers decreased by 18,000 over the past month, its fifth straight decline, returning to 2.841 million according to figures adjusted for seasonal variation (CV) published ; s Thursday by the Federal Labour Office.

This decrease is more pronounced than expected since the 35 economists polled by Reuters had expected a decline of 10,000. 

"The resilience of the German labor market bodes well for private consumption in the first half," commented Carsten Brzeski, economist at ING.

"The mild weather in March and almost unwavering optimism of entrepreneurs seem the main drivers of the improvement of the fall in unemployment announced today."

These figures are good news for the German finance minister, Wolfgang Schaeuble, whose estimates are based largely on increased tax revenues.

They also enhance the contrast between Germany and France, where the numbers of unemployment in February hit their highest level since October 1999. 

While the German population is nearly 30% higher than the French, the number of jobseekers CVS is now lower than that of unemployed Class A in the Hexagon.

SALARY INCREASES OF POSSIBLE

4%

If the German economy, driven by exports, has recovered quickly from the 2008-2009 financial crisis, it has not escaped the relapse caused the end of 2011, contracting by 0.2% in the fourth quarter due to the debt crisis in the euro area and its impact on global demand. 

It seems to be resurged since the beginning of this year, which led several economic research institutes to raise their growth projections and e ; housing with near certainty the hypothesis of a new recession (two consecutive quarters of declining GDP).

Buoyant labor market in this climate generally heckled favored improving consumer confidence, rising in six of seven months as the barometer of the GfK. 

The decline in unemployment has led parallel to the German unions claim higher wages after several years of rigor in this area: the central Verdi and IG Metall and ask one the other increases of 6.5% for the approximately five million workers they represent.

For Christian Schulz, an economist at Berenberg Bank, wage growth is "inevitable" because of tensions on the labor market.

"While it is unlikely that requests for increases of 6% are accepted, agreements with increases of 4% are possible," said he. "With inflation back to 2.1% in March, wage increases may provide important new welcome boost to consumer spending."

Many economists note, however, that the downward trend in unemployment slows as lessens the impact of reforms implemented in recent years to increase the flexibility of the labor market .

At 4:16 p.m., the action of the oil giant posted the largest decline in the CAC 40, yielding 6.57% to 38.31 euros, its lowest level in three months. The title acknowledges its biggest drop since December 2008 and saw its market capitalization and nearly melted almost six billion euros.

At this stage, investors are more concerned about the impact of leakage on the group's production and its consequences on the environment and the prudent play while waiting to get an idea pre Cise of the magnitude of the disaster.

"Investors apply the precautionary principle in a situation still uncertain, in memory with the recent accident that affected BP," said Romain Burnand, co-director of Moneta Asset Management. 

The explosion and sinking and the Deepwater Horizon, in the Gulf of Mexico, eleven had died in April 2010. Some 4.9 million barrels of crude oil had escaped from the Macondo well, drilled on behalf of the "major" British Petroleum. After the disaster, BP had lost more than 52% of its stock value in less than two months.

"With the memory of Macondo, the market remains very nervous about this kind of news until the problem is not quantified," says one trader.

"This event will impact Total's production and creates a risk of pollution, limited at this stage, but not yet identified," he says, noting that the group is still undecided in his faç ; we deal with the incident.

TWO OPTIONS

Total has indeed explained explore all possible options to deal with the gas leak on the platform Elgin-Franklin, including drilling a relief well, an operation that could take six months.

"There are two options for intervention. One is to drill a relief well, which could take about six months. The other is an intervention on the platform to seal the well (…) what would be a faster option, "he told Reuters David Hainsworth, safety manager, health and environment at Total Exploration & Production UK

. "We plan to decide on a course in the coming days," he In addition to mobilizing added

. 10 to 20 engineers, the group has engaged the services of Wild Well Control, society that occurred during the oil spill in the Gulf of Mexico in 2010

. Total said Monday it has stopped production and have evacuated its staff on site (238 people), after the leak occurred Sunday. 

The platform was producing nine million cubic meters of gas per day, equivalent to 3% of UK production of natural gas and 60,000 barrels per day of light crude.

The gas cloud that formed around the platform, located off Scotland to 240 kilometers east of Aberdeen, has forced Shell to evacuate employees of two neighboring platforms for safety reasons.

The leak has formed a cloud dense enough to be visible to other platforms in the North Sea. Shell has decided to suspend, as a precaution, to drill on one of them.

The environmental consequences of leakage of natural gas condensates are much less serious than those of oil spills, has informed the British Minister of Energy.

An exclusion zone of sea and air, however, was declared around the platform, said Total.

The remuneration of top managers in the U.S. rose 1.4% in 2011 against an increase of 11% in 2010, according to partial results of a study released Monday by the Wall Street Journal. "Despite a sizeable increase in earnings and business income, earnings of 65 bosses in office for at least two years rose by only 1.4%" in 2011, says the U.S. daily.

The Wall Street Journal explains the stagnation in the bond of increasingly close relationship between compensation and employers' business performance, because of the "monitoring" of shareholders and the "pressure" the Securities and Exchange Commission (SEC ). The SEC, the U.S. federal agency to regulate financial markets, calls for "more details" on how companies pay their executives, which complicates the payment of bonuses by adjusting in-year objectives, explains daily.

The partial study, conducted by management consulting firm Hay Group, based at the moment of 75 U.S. companies, whose net income grew 17% in 2011. The full study, which involves 300 companies, will be published "later this spring," announces the Wall Street Journal. According to preliminary results, the median earnings of bosses is 9.4 million in 2011, against $ 9.3 million according to comprehensive study of 2010.

The remuneration of the boss of Apple, Tim Cook, is estimated at $ 378 million in 2011. That of the boss of media group Viacom, Philippe Dauman, who dominated the rankings in 2010 with a salary estimated at $ 84.3 million, is 42 million in 2011.
